Ask a Kolkata founder what they want to put on the front of their new supplement and the answer is often the same: “immunity booster.” It is the phrase customers search for, and it is also the phrase regulators watch most closely. So if you are looking for an immunity supplement third party manufacturer Kolkata brands can trust, the first decision is not the format or the flavour. It is what you are actually allowed to say.
This guide explains how contract manufacturing for immunity products works, what the claims rules mean in practice, which licence route applies to herbal and non-herbal products, and what to ask D10 Enterprises if you build your brand in Kolkata and manufacture elsewhere.
Why Kolkata Brands Manufacture Outside the City
Kolkata has a long habit of trusting herbal and traditional wellness products, and a customer base that still reads labels closely. What it lacks is affordable industrial space for clean production halls, extraction and blending rooms and storage. So most brands here run marketing and sales locally and use a licensed factory in another state.
D10 Enterprises works from Ajit Nagar, Ambala Cantt, Haryana, and has no Kolkata unit. For a brand owner, what matters is honest communication, good samples and dispatch that arrives on time.
The Claims Problem
“Immunity” sounds like a harmless word, but it carries real risk. FSSAI’s Advertising and Claims Regulations, 2018 allow nutritional, health and disease risk reduction claims that are listed in the regulation, and anything else needs prior approval from the Food Authority. Claims must also be scientifically substantiated.
Enforcement is not theoretical. In a 2026 action against a nutraceutical brand, FSSAI treated claims such as “Boost your immune system” as lacking scientific support, and also objected to wording like “healthy” in a brand name. The Advertising Standards Council of India has likewise asked brands to prove or withdraw immunity claims in advertising.
What does this mean for you? Decide your claims with your manufacturer before you design packaging. A product can describe what it contains, for example the vitamins and minerals in it, without promising an outcome the evidence cannot support. A manufacturer who reviews your wording before printing is protecting you from a real risk. D10 lists regulatory operations and support and a quality, safety and compliance programme, so ask exactly what they review.
Two Routes: Supplement or Herbal Medicine
Many immunity products in Kolkata are herbal, and the licence route depends on how the product is positioned. A general health supplement falls under FSSAI’s 2022 nutraceutical regulations. These need the words “HEALTH SUPPLEMENT” in capital, bold letters near the product name, and ingredients must come from the permitted lists. Health supplement manufacturing also sits in FSSAI’s mandatory Central License category.
A product sold as an Ayurvedic medicine falls under AYUSH rules instead, where the manufacturer holds an AYUSH licence, or a brand holds a loan licence while using a licensed factory. The two routes carry different labels and different claim rules, so settle which one you are on at the start, not after samples arrive.
D10 lists a herbal medicines range covering syrup, tonics, tablets and powder, which you can see on its herbal medicines page, and a nutraceuticals range on its nutraceuticals manufacturing page listing syrup, softgel capsules, protein powders and mouth spray. The nutraceutical catalogue shared by the company also covers tablets and capsules, sachets and oral spray, and gummies are part of what D10 makes as well. The product catalog shows the wider range. Ask them which licence applies to the exact product you have in mind.
Choosing a Format
A tonic or syrup suits the whole family and fits herbal tradition, though liquids need careful preservation and stability testing. Tablets and capsules are stable, cheap and easy to carry. Powders and sachets suit blends that go into water or milk. Gummies suit people who dislike swallowing pills, though each piece carries a small dose. Pick the format your customer already uses, not the one that looks trendy.
White Label Immune Support Versus Custom Formulation
White label immune support means choosing a formula the manufacturer already makes and putting your brand on it. It is quicker, with lower minimum orders and no development time.
Custom formulation means a blend built around your brief, such as a particular mix of vitamins, minerals or herbs. It takes longer and needs more sample rounds, but the product is yours alone. D10 lists custom formulation solutions and private branding and labeling as separate services. If you later want to hold your own licence, it also lists loan licensing services.
How the Process Usually Runs
You send a brief: format, ingredients, target customer, pack style, first order size and the claims you hope to make. The manufacturer checks ingredients against the relevant lists, proposes a recipe and sends samples. After approval, packaging and label artwork are finalised and your claims are reviewed. Production runs in batches, each is tested, and finished stock is dispatched.
For a Kolkata brand, ask how bottles are packed for freight and for humid weather. Tonics in glass need protection, and powders and tablets need moisture control.
Questions to Ask a Contract Wellness Producer
- Which licence do you hold for the product type I want, FSSAI Central, AYUSH or both?
- Have you made a product with similar ingredients before?
- Will you review my label wording and claims before printing?
- How do you check dose accuracy and stability?
- What is the minimum order quantity for a first batch?
- What packaging do you suggest for Kolkata’s climate?
- How long does dispatch take?
What Shapes the Price
Cost depends on the ingredients and their quality, the format, batch size, packaging, label printing, testing and freight. Herbal raw materials can vary in price with season and source. Ask for a written breakdown by stage so you can compare quotes properly.
Common Mistakes
The first is printing “immunity booster” on a pack without checking what is allowed. The second is choosing the wrong licence route for how the product is positioned. The third is skipping stability testing. The fourth is launching a big range at once. The fifth is picking a factory on price without seeing its licence.
Getting Started
Before contacting any manufacturer, write a short brief: format, key ingredients, target customer, whether the product is a supplement or a herbal medicine, pack style, first order size and launch date.
