Nutraceuticals: Still An Oasis Amidst Well-Regulated Pharmaceuticals

Posted on by

On November 24, 2016, the food-safety watchdog of India announced that health supplements or Nutraceuticals cannot be sold as ‘medicines’ anymore. This new regulatory standard has been set for the manufacturers of Nutraceuticals and food supplements, and is aimed at controlling mislabeling of such brands. The fine prints of the notification are yet to be assessed.

On the face of it, this new announcement seems to be a good step, and would largely address a long-standing issue on the such products. Prevailing undesirable practices of labeling some pharma brands as food supplements or Nutraceuticals, with some tweaking in the formulations, mainly to avoid the risk of price control, is also expected to be taken care of by the food-safety authority of India, while granting marketing approval.

Nevertheless, it is often construed that off-label therapeutic claims, while promoting these products to the doctors, help achieving brand positioning objective as medicines, though indirectly. Appropriate authorities in India should probably resolve this issue, expeditiously.

In this article, I shall focus on the rationale behind different concerns over the general quality standards, claimed efficacy and safety profile of Nutraceuticals and food supplements, in general, and how the regulatory authorities are responding to all these, slowly, albeit in piecemeal, but surely.

The ‘gray space’ is the issue:

The close association between nutrition and health has assumed a historical relevance. Growing pieces of evidence, even today, suggests that nutritional intervention with natural substances could play an important role, especially in preventive health care. The World Health Organization (WHO) has also highlighted that mortality rate due to nutrition related factors in the developing countries, like India, is nearly 40 percent.

However, as one of the global consulting firm of repute has aptly pointed out, “At one end of this natural nutrition spectrum, are functional foods and beverages as well as dietary supplements, aimed primarily at maintaining health. On the other, more medical end of the spectrum, are products aimed at people with special nutritional needs. In the middle, is an emerging gray area of products that have a physiological effect to reduce known risk factors, such as high cholesterol, or appear to slow or prevent the progression of common diseases such as diabetes, dementia or age related muscle loss.”

This gray space between Pharmaceutical and Nutraceuticals, therefore, holds a significant business relevance, from various perspectives.

An Oasis amidst highly-regulated pharmaceuticals:

Mostly because of this gray space, several pharma companies and analysts seem to perceive the Nutraceutical segment virtually an oasis, lacking any transparent regulatory guidelines, amidst well-regulated pharma business. This perception is likely to continue, at least, for some more time.

Such pattern can be witnessed both within the local and global pharma companies, with some differences in approach, that I shall deliberate later in this article.

However, regulators in many countries, including India, have started expressing concerns on such unfettered manufacturing, marketing and other claims of Nutraceuticals. Many of them even ask, do all these Nutraceuticals deliver high product quality, claimed effectiveness and safety profile to their consumers, especially when, these are promoted by several pharma companies, though mostly off-label, to generate physicians’ prescriptions for various disease treatments?

Not just domestic pharma companies:

This concern is not restricted to the domestic companies in India.

Global pharma players, who generally believe in scientific evidence based medicines, have been reflecting an iffiness towards Nutraceuticals. For example, whereas both Pfizer and Novartis reportedly hived off their nutrition businesses, later Pfizer invested to acquire Danish vitamins company Ferrosan and the U.S. dietary supplements maker Alacer. Similarly, both Sanofi and GlaxoSmithKline also reportedly invested in mineral supplements businesses that could probably pave the way of the company’s entry into medical foods.

However, it is worth underscoring that generally the consumer arms of global pharma companies focus on OTC, and Nutraceuticals do not become an integral part of the pharma business, as is common in India.

Interestingly, not very long ago, Indian pharma industry witnessed a global pharma major virtually replicating the local marketing model involving Nutraceuticals. It also became an international news. On August 24, 2011, ‘Wall Street Journal (WSJ)’ reported that ‘Aventis Pharma Ltd. (now Sanofi India) agreed to buy the branded nutrition pharmaceuticals business of privately held Universal Medicare Pvt. Ltd for an undisclosed amount, as its French parent Sanofi looks to expand in the fast-growing Indian market.’

Universal Medicare, which posted about US$ 24.1 million revenue in the year ended March 31, 2011, will manufacture these branded Nutraceutical products and Aventis will source them from Universal Medicare on mutually agreed terms. Around 750 of the Universal Medicare’s employees also moved to the French Company along with its around 40 Nutraceutical brands, the report said.

If all these acquired brands, do not fall under the new FSSAI guidelines related to the required composition of food supplements and Nutraceuticals in India, it would be worth watching what follows and how.

Nutraceuticals are also promoted to doctors:

Let me reemphasize, India seems to be slightly different in the way most of the pharma companies promote Nutraceuticals in the country. Here, one can find very few standalone ‘Over the Counter (OTC)’ pharma or Nutraceutical product company. For this reason, Nutraceutical brands owned by the pharma companies, usually become an integral part of their prescription product-portfolio. Mostly, through off-label promotion Nutraceuticals are often marketed for the treatment or prevention of many serious diseases, and promoted to the doctors just as any other generic pharma brand.

Need to generate more scientific data based evidences:

A 2014 study of the well-known global consulting firms A.T. Kearney titled, “Nutraceuticals: The Front Line of the Battle for Consumer Health”, also recommended that ‘a solid regulatory framework is crucial for medical credibility, as it ensures high-quality products that can be relied on to do what they say they do.’

This is mainly because, Nutraceuticals are not generally regarded by the scientific community as evidence based medicinal products, going through the rigors of stringent clinical trials, including pharmacokinetics and pharmacodynamics studies, and is largely based on anecdotal evidence. Besides inadequacy in well-documented efficacy studies, even in the areas of overall safety in different age groups, other side-effects, drug interactions and contraindications, there aren’t adequate scientific evidence based data available to Nutraceutical manufacturers, marketers, prescribers and consumers.

There does not seem to be any structured Pharmacovigilance study is in place, either, to record adverse events. In this scenario, even the ardent consumers may neither realize, nor accept that Nutraceuticals can cause any serious adverse effects, whatsoever.

From this angle, the research study titled, “Emergency Department Visits for Adverse Events Related to Dietary Supplements”, published in the  New England Journal of Medicine (NEJM) on October 15, 2015, becomes very relevant. The paper concluded as follows:

“More than 23,000 emergency department visits annually in the United States from 2004 through 2013 were for adverse events associated with dietary supplements. Such visits commonly involved cardiovascular adverse effects from weight-loss or energy herbal products among young adults, unsupervised ingestion of micronutrients by children, and swallowing problems associated with micronutrients among older adults. These findings can help target interventions to reduce the risk of adverse events associated with the use of dietary supplements.”

Fast growing Nutraceutical industry continues to remain largely unregulated. It persists, even after several previous studies had revealed dangerous levels of harmful ingredients, including amphetamine, in some Nutraceuticals.

Indian regulatory scenario:

In India, the ‘Food Safety and Standards Authority of India (FSSAI)’, established under the Food Safety and Standard Act of 2006, is the designated Government body responsible for the regulation and approval of Nutraceuticals in the country.

In July 2015, FSSAI proposed draft regulations for Nutraceuticals, Functional Foods, Novel Foods and Health Supplements for comments from all stakeholders within the stipulated time limit. This draft regulation defines Nutraceuticals as follows:

“Nutraceuticals means a naturally occurring chemical compound having a physiological benefit or provide protection against chronic disease, isolated and purified from food or non-food source and may be prepared and marketed in the food-format of granules, powder, tablet, capsule, liquid or gel and may be packed in sachet, ampoule, bottle, etc. and to be taken as measured unit quantities.”

In this draft FSSAI also proposed that therapeutic claims of Nutraceuticals and all such foods are required to be based on sound medical and nutritional evidence, backed by scientific as well as clinical evidence.

In 2011, FSSAI constituted a product approval committee, whose members were supposed to use similar parameters as drugs, to assess Nutraceuticals for this purpose. However, FSSAI had to jettison this idea, in compliance with the order dated August 19, 2015 of the Supreme Court questioning the procedure followed for approvals by the food regulator.

In April 2016, FSSAI restricted enforcement activity against Nutraceuticals and health supplement companies to only testing of products till new standards are notified.

The latest regulatory developments:

There are, at least, the following two recent developments reflect that the regulatory authorities, though trying, but are still grappling with the overall product quality, efficacy and safety concerns for Nutraceuticals:

  • Responding to the growing demand for regulatory intervention in this important matter, on November 30, 2015, by a gazette notification, the Government of India included phytopharmaceutical drugs under a separate definition in the Drugs & Cosmetics (Eighth Amendment) Rules, 2015, effective that date.
  • Again, on November 24, 2016, FSSAI reportedly announced that health supplements or Nutraceuticals cannot be sold as ‘medicines’ anymore. This new regulatory standard set for the manufacturers of Nutraceuticals and food supplements is aimed at controlling mislabeling of such brands. On its enforcement, every package of health supplement should carry the words ‘health supplement’ as well as an advisory warning ‘not for medicinal use’ prominently printed on it.

It further added: “The quantity of nutrients added to the articles of food shall not exceed the recommended daily allowance as specified by the Indian Council of Medical Research and in case such standards are not specified, the standards laid down by the international food standards body namely the Codex Alimentarius Commission shall apply.”

However, these regulations will be enforced from January 2018.

Curiously, in September 2016, National Institutes of Health in United States announced plans to put some more scientific eyes on the industry, the NIH reportedly announced plans to spend US$ 35 million to study natural products, ranging from hops to red wine’s resveratrol to grape seed extract. The new grants, reportedly, are expected to fathom the basic science behind many claims that Nutraceuticals can improve health.

The market:

The August 2015 report titled, ‘Indian Nutraceuticals, Herbals, and Functional Foods Industry: Emerging on Global Map,’ jointly conducted by The Associated Chambers of Commerce and Industry of India (ASSOCHAM) and the consulting firm RNCOS, estimates that the global Nutraceuticals market is expected to cross US$ 262.9 billion by 2020 from the current level of US$ 182.6 billion growing at Compound Annual Growth Rate (CAGR) of about 8 percent.

Driven by the rising level of awareness of health, fitness and changing lifestyle pattern, increasing co-prescription with regular drugs, and focus on preventive health care, India’s Nutraceuticals market is likely to cross US$ 6.1 billion by 2020 from the current level of US$ 2.8 billion growing at CAGR of about 17 percent, the report states.

The United States (US) has the largest market for the Nutraceuticals, followed by Asia-Pacific and European Union. Functional food is the fastest growing segment in the US Nutraceutical market, followed by Germany, France, UK and Italy in Europe.

Conclusion:

Today, both manufacturing and marketing of Nutraceuticals keep charting in a very relaxed regulatory space, in India. There are no robust and transparent guidelines, still in place, for product standardization and scientifically evaluate the safety and efficacy of all these products on an ongoing basis. Neither is there any stringent requirement for conformance to the well-crafted cGMP standards.

The reported discussions within the Union Ministry of Ayush for setting up a structured regulatory framework, within the CDSCO, for all Ayush drugs and to allow marketing of any new Ayurvedic medicine only after successful completion of clinical trials to ensure its safety and efficacy, are indeed encouraging. This may be followed for all those Nutraceuticals, which want to be promoted as medicines, claiming direct therapeutic benefits.

Be that as it may, November 24, 2016 announcement of FSSAI, that health supplements or Nutraceuticals cannot be sold as ‘medicines’ anymore to control mislabeling of such brands, is a step in the right direction.

Another major issue of many pharma brands being put under Nutraceuticals with some tweaking in formulations and labelled as food supplements, would also probably be largely addressed, as FSSAI would continue to be the sole authority for marketing approval of Nutraceuticals.

However, it is still not very clear to me, as I am writing this article, what happens to those Nutraceutical brands, which are already in the market, with compositions not conforming to the new FSSAI norms. Fairness demands reformulation and relabeling of all those existing Nutraceuticals, strictly in conformance to the new guidelines, and obtain fresh approval from FSSAI. This will help create a level playing field for all Nutraceutical players in India.

While there is a pressing need to enforce a holistic regulatory discipline for the Nutraceuticals to protect consumers’ health interest, the commercial interest of such product manufacturers shouldn’t be ignored, either. This is primarily because, there exists enough evidence that proper nutritional intervention with the right kind of natural substances in the right dosage form, could play an important role, especially in the preventive health care.

As the comprehensive regulatory guidelines are put in place, Nutraceuticals not being essential medicines, should always be kept outside price control, in any guise or form. In that process, the general pharma perception of Nutraceutical business, as an ‘Oasis’ amidst well-regulated and price-controlled pharmaceuticals, would possibly remain that way, giving a much-needed and well-deserved boost to this business.

Nutraceuticals: An Emerging Opportunity in The Gray Area Between Pharma And Nutrition

Posted on by

Close association between nutrition and health has assumed a historical relevance. Growing pieces of evidence, even today, suggests that nutritional intervention with natural substances could play an important role, especially in the preventive healthcare. The World Health Organization (WHO) too has highlighted that mortality rate due to nutrition related factors in the developing countries, like India, is nearly 40 percent.

The ‘Gray Area’:

In the space between pharmaceutical and nutrition, there is an emerging ‘gray area with 50 shades’ having significant business relevance.

In a related publication, A.T. Kearney – a leading global management consulting firm has elaborated it as under:

“At one end of this natural nutrition spectrum, are functional foods and beverages as well as dietary supplements, aimed primarily at maintaining health. At the other, more medical end of the spectrum, are products aimed at people with special nutritional needs. In the middle, is an emerging gray area of products that have a physiological effect to reduce known risk factors, such as high cholesterol, or appear to slow or prevent the progression of common diseases such as diabetes, dementia or age related muscle loss.”

Evolution of the terminology ‘Nutraceuticals’:

Dr. Stephen DeFelice of the ‘Foundation for Innovation in Medicine’ coined the term ‘Nutraceutical’ from “Nutrition” and “Pharmaceutical” in 1989. The term nutraceutical though is now being commonly used in marketing such products has no regulatory definition, other than dietary or nutritional supplements.

It is interesting to note that the dietary supplement industry defines nutraceuticals as, “any nontoxic food component that has scientifically proven health benefits, including disease treatment and prevention.”

Probably because of this reason, it is often claimed by the manufacturers of nutraceutical products that these are not just dietary supplements, but also help in the prevention and/or treatment of many disease conditions.

In India, nutraceuticals are mostly promoted to the doctors just as any other ethical pharma products. These are also prescribed by the medical profession, not just as nutritional supplements but also for the treatment of disease conditions, ranging from obesity to arthritis, osteoporosis, cardiological conditions, diabetes, anti-lipid, gastroenterological conditions, dementia, age-related muscle loss, pain management and even fertility. All these are generally based on off-label therapeutic claims of the respective manufacturers.

Currently, this particular category of nutraceutical products, despite being out of price control and operating within much relaxed regulatory environment, is showing just a moderate growth trend in India.

The market:

According to a report of Frost & Sullivan, the global nutraceutical market has clocked maximum growth in the last decade.

Nutraceuticals as an industry emerged in the early 1990s. However, from 2002 to 2010 has been the key growth phase for the industry. From 1999 to 2002, the nutraceutical industry grew at an Annual Average Growth Rate (AAGR) of 7.3 percent, while from 2002 to 2010, the AAGR doubled to 14.7 percent, in line with the Indian Pharma Market (IPM).

The penetration of nutraceuticals in India was around 15 percent in 2013. In the same year, the turnover of the global nutraceuticals market was around US $168 billion in which India had a demand share of around 2 percent, i.e. around US $2 billion.

Growing at a Compound Annual Growth Rate (CAGR) of 17.1 percent, the Indian market is expected to reach US$ 4 billion by 2018. China, Southeast Asia, and India are the fast-growing markets, with each experiencing growth in double digits.

In the last couple of years functional beverages have emerged as a fastest growing category for the Indian market, with many companies expanding their portfolio in the segment. This category is expected to grow at a CAGR of 21.7 percent by 2018.

However, in terms of ingredients, especially plant extracts and phytochemical, Indian manufacturers have entrenched their place as suppliers, both locally as well as globally.

Some other key findings of this report are as under:

  • India is currently a nascent market for nutraceuticals, without a robust business model in place. Both MNCs as well as domestic companies in the pharmaceutical and food and beverage space have tested the market with a variety of launches, with some degree of success.
  • The existence of alternative medicines in India, and the Indian consumer’s belief in them, could provide a platform for the nutraceutical industry to cash on.
  • The Indian consumers’ awareness about conventional nutraceutical ingredients such as omega-3 fatty acids or lutein is very limited. The nutraceutical manufacturers would require spreading awareness about their products to the Indian masses, much more effectively.
  • As compared with the developed countries such as the USA, Europe, and Japan, the percentage of population consuming nutraceuticals in India is much low. The middle to high income groups are the dominant consumers of functional foods and beverages along with dietary supplements, while the lower income groups consume mainly prescription-based dietary supplements.
  • Health awareness and an increase in the penetration of organized retail stores are expected to play a major role in driving the nutraceuticals’ consumption in India.

Current regulations in India:

The Food Safety and Standards Act (FSSA) of India, 2006 predominantly regulate manufacturing, storage, distribution, sale and import of nutraceuticals in India. Unlike pharma products, no other regulations are still in place, though the government reportedly is in the process of inviting suggestions from the stakeholders on the subject.

Experts feel that FSSAI needs to play a more important role in defining standards to streamline the operations for nutraceuticals business in India, which should include, besides others, the following:

  • Quality of raw materials
  • Safe manufacture of product with cGMP standards
  • Health claims
  • Labeling
  • Distribution & storage

In the absence of comprehensive regulations many companies are unable to decide on necessary investments that will be required for this business in the longer term.

Currently, nutraceuticals are much less expensive to develop, manufacture, market and distribute, offering a rainbow of business opportunities in the healthcare space.

A brand ‘New Ministry’ in place:

In all likelihood, renewed measures would now be taken to bring nutraceuticals under the mainstream healthcare.

It appears more feasible today than ever before, as the Prime Minister Modi, with an eye on reviving indigenous and traditional medicine has recently created a brand new ministry with a Minister of State (Independent Charge) at the helm to look after Department of Ayurveda, Yoga and Naturopathy, Unani, Siddha and Homeopathy (AYUSH).

Need to generate robust clinical data:

In this context, a relatively new development is worth noting. It has been reported that all new traditional medicines will need to undergo clinical trials before their regulatory marketing approval in India. However, it has also been amply clarified that “such products will include only the new patented drugs and not the classical formulations that find mention in India’s ancient texts, some of which are 5,000 years old.”

I reckon, for all nutraceutical formulations with specific therapeutic efficacy and safety claims, there is a need to generate supportive robust clinical data for the patients’ long term health interest.

Therapeutic efficacy of a drug in the treatment of a disease condition is established with pharmacokinetic, pharmacodynamics, other pre-clinical and clinical studies. Some experts believe that these studies are very important for nutraceutical products too, particularly when therapeutic claims are made on them, as these substances undergo a series of reactions within the body.

Similarly, to rule out any long-term toxicity problem with such products, generation of credible clinical data is again critical. At present, these are not usually followed for nutraceutical products in India, even when therapeutic claims are made.

The experts, therefore, quite often say, “A lack of reported toxicity problems with any nutraceutical should not be interpreted as evidence of safety.”

Regulatory requirements for nutraceuticals in the USA:

In America, the Congress had passed the ‘Dietary Supplement Health and Education Act’ in 1994. This act allows ‘functional claims’ to dietary supplements, like “Vitamin A promotes good vision” or “St. Johns Wort maintains emotional well-being”, as long as the product label contains a specific disclaimer that the FDA has not evaluated the said claim and that the product concerned is not intended to diagnose, treat, cure or prevent disease.

The above Act bestows some important responsibility on to the doctors, who are required to provide specific and accurate scientific information for nutraceutical products to their patients. This process assumes critical importance, as the patients would expect the doctors to describe to them about the usefulness of nutraceutical products as alternatives to approved drugs. In such cases, if any doctor recommends a dietary supplement instead of pharmaceutical products, the doctor concerned must be aware of the risk that the patient’s health may suffer, for which the affected patient could sue the doctor for malpractice.

Indian Health Ministry should take note of these points for ethical promotion of nutraceuticals in India.

Sanofi considered nutraceuticals as a business opportunity in India:

So far in India, Sanofi is the only Pharma MNC that has entered into nutraceuticals business in a big way. Sniffing the market opportunity in this segment, the French major acquired the nutraceuticals business of Universal Medicare Private Ltd of worth Rs.110 Crore, in August 2011. The nutraceuticals product portfolio of Universal Medicare included more than 40 brands from cod liver oil capsules, vitamins/mineral supplements and antioxidants to liver tonics.

Ambivalence of Pharma MNCs:

According to A.T. Kearney report, unlike food industry, the global pharma industry has approached nutraceuticals with a ‘great deal of ambivalence’.

Pfizer and Novartis have sold their nutrition businesses.While the same Pfizer that sold Wyeth Nutrition to Nestle, invested an undisclosed sum to acquire Danish vitamins company Ferrosan and the dietary supplements manufacturer of the United States, Alacer, reinforcing what was already a billion-dollar business enterprise.

On the other hand GlaxoSmithKline (GSK) and Novartis have recently announced a joint venture for consumer products business, which could probably be a stepping-stone to get into nutraceuticals. Who knows?

Food companies leading nutraceuticals business:

The A.T. Kearney report also states that at present the food companies, and not the pharma players, are in the lead, accounting for about 90 percent of nutraceuticals sales with expertise in branding, consumer market expertise and access to mass distribution channels.

A few consumer companies have also inked partnership with pharma companies. For example, Coca-Cola and Sanofi have partnered to sell health drinks in French pharmacies.

Conclusion:

Nutraceuticals business, as many believe, is an emerging opportunity in the ‘Gray Area’ between pharmaceuticals and nutritional product classes. So far, the food companies have been charting this frontier that remained uncharted by a large majority of the pharma players. This is mainly because the success requirements for nutraceutical products, including dietary supplements, are quite different.

That said, a transparent and well-charted regulatory pathway for nutraceuticals, especially for formulations with therapeutic claims, would have a significant impact on its future growth potential in India.

Many nutraceutical products in the country with specific therapeutic claims do not seem to have supporting robust clinical data, leave aside being peer reviewed and published in the reputed international journals on the claims for safety or efficacy.

The entry of one of the global majors, Sanofi, having a clear focus on Evidence Based Medicines (EBM), ushers in a new hope and promise to get the loose knots tightened in this important area, while driving the business growth of the category.

Just as EBM, scientific ‘Evidence Based Nutraceuticals (EBN)’ with therapeutic claims, should be the centerpiece of consumer confidence and interest in this emerging niche of healthcare business in India.
