Stand in front of the nutrition shelf of any pharmacy in Kochi and you’ll see dozens of tubs and sachets, each promising strength, immunity, energy, recovery. Ask the person beside you what the difference is between a “health supplement”, a “nutraceutical” and a “food for special medical purposes”, and you’ll most likely get a shrug. Many doctors would shrug too.
The distinction matters, especially if you’re buying for an older parent or someone who is ill. So here’s a plain-language guide.
A disclosure first: I’m involved in a company that is developing medical nutrition products. That’s partly why I care that these categories are understood properly. Nothing in this article is about any particular product, and none of it is a recommendation to buy anything.
First, all of these are foods
In India, these products are regulated by the Food Safety and Standards Authority of India (FSSAI), under its nutraceutical regulations (first framed in 2016 and revised since). Not one of them is a medicine. They are not allowed to claim that they prevent, treat or cure a disease. If a label or an advertisement tells you a powder will “cure” diabetes, arthritis or cancer, that is a red flag about the seller, not a feature of the product.
The three you’ll meet most often
| Health supplement | Nutraceutical | Food for Special Medical Purpose (FSMP) | |
|---|---|---|---|
| What it is | Concentrated nutrients (vitamins, minerals, protein and so on) to supplement a normal diet | Naturally occurring substances, extracted or purified, taken in measured amounts for a physiological benefit | Specially formulated nutrition for people whose illness means ordinary food can’t meet their needs, as part of the dietary management of a condition |
| Meant for | Generally healthy people | Generally healthy people | People with a specific disease, disorder or medical condition |
| Medical supervision | Not required | Not required | Required: to be used under medical advice |
| Label you may see | Nutrient content, recommended use, a statement that it is not for medicinal use | Similar to supplements | A statement that it is to be used under medical advice, and the condition it is intended for (“for the dietary management of …”) |
There are other categories too, such as foods for special dietary use, and probiotic and prebiotic foods. These three cause the most confusion.
Why the FSMP category exists
Picture a man recovering from a stroke who can swallow only thickened liquids. Or a woman with severe kidney disease whose diet must be strictly balanced. Or a patient in an ICU fed entirely through a tube. For these people, “eat a balanced diet” isn’t possible advice. Their nutrition has to be designed around the condition.
That’s what FSMPs are for. Because the people using them are ill, and because the product may be their main or only source of nutrition, the rules are stricter. They require a medical professional’s guidance, and the regulator expects a scientific justification for how the product is formulated.
Three questions to ask before you buy
1. Does this person need it at all? A healthy older adult who eats reasonably well usually gets more benefit from food and exercise than from a tub. If appetite is poor, weight is falling, or muscle is wasting, the first step is a proper assessment, not a purchase.
2. Which category is it, really? Read the label, not the advertisement. If it says it’s to be used under medical advice, then please take medical advice, especially for someone with diabetes, kidney disease or swallowing problems.
3. Does it fit with everything else? Some supplements interact with medicines. Extra potassium, vitamin K or certain herbal extracts can matter a lot for someone on blood thinners or with weak kidneys. Bring the tub to your next doctor’s appointment. We don’t mind. We’d much rather know.
A word to my medical colleagues
We often recommend “a protein supplement” in the same tone we’d suggest a walk. For the frail, malnourished or acutely ill patient, the choice of nutrition product is a clinical decision, and deserves the same thought as a prescription: what, how much, for how long, and how will we know it is working?
The bottom line
The shelf is crowded, the language is confusing and the marketing is loud. The categories, though, are simple. Supplements and nutraceuticals add to a normal diet for healthy people. FSMPs are medical nutrition for people who are ill, used with a professional’s guidance. None of them is a medicine, and none can honestly promise a cure.
