Omega-3 and Fish Oil Supplement Manufacturing in India
Fish oil oxidises, and an oxidised omega-3 supplement smells and tastes of it long before anything else fails. EPA and DHA content, peroxide and anisidine values, and heavy metals are the four parameters that matter.
What Determines Quality Here
This guide is for brand owners developing omega-3 supplements in India.
Four things determine whether an omega-3 product is good. The first is actual EPA and DHA content, which is not the same as the oil weight. A one-gram fish oil capsule may contain anywhere from a small to a large proportion of EPA and DHA depending on the oil’s concentration, and the declaration should state the EPA and DHA amounts rather than only the oil weight.
The second is oxidation state. Marine oils oxidise readily, and oxidation produces the fishy smell and taste consumers complain about, as well as degrading the product. Peroxide value and anisidine value are the measures, and both should be specified with maximums and required per batch.
The third is heavy metals, since the oil comes from marine sources. The fourth is the source and its documentation, which bears on both the non-vegetarian declaration and any sustainability positioning.
Obtain professional regulatory advice on the applicable declarations and framework before proceeding.
Specification Points
What belongs in your purchase specification.
| Element | What to Specify | Why |
|---|---|---|
| Source | Species or source type, documented | Declaration and positioning |
| Oil form | Triglyceride, ethyl ester or other | Affects concentration and handling |
| EPA content | Milligrams per gram, with method | The actual active |
| DHA content | Milligrams per gram, with method | The actual active |
| Total omega-3 | Where declared | Label accuracy |
| Peroxide value | Maximum | Oxidation measure |
| Anisidine value | Maximum | Secondary oxidation measure |
| Free fatty acid value | Maximum | Quality indicator |
| Heavy metals | Each with a maximum, per batch | Marine source |
| Dioxins and PCBs | As advised for marine oils | Source-dependent contaminants |
| Antioxidant system | Named, with level | Protects the oil |
| Odour and taste | Approved against a sample | Consumer acceptance |
| Certificate of analysis | Per batch, methods named | Non-negotiable |
Dioxins and PCBs are relevant to marine oils and should be discussed with your professional adviser and laboratory. They are not part of a standard supplement panel and need requesting specifically.
The Softgel Decision
The usual format, with its own requirements.
Shell Material
Usually gelatin, which is animal-derived. Plant-based softgel shells exist and must be specified if required. Either way the non-vegetarian declaration follows the fill as well.
Shell Integrity
A leaking softgel is the most common complaint in this category. Specify seal integrity testing per batch.
Shell and Oil Interaction
The fill can affect the shell over time, causing softening or brittleness. Require stability assessment of the shell, not just the oil.
Enteric or Coated Options
Available to reduce reflux and aftertaste. More expensive, and dissolution behaviour must be confirmed.
Softgel shell behaviour in Indian conditions deserves specific attention. Heat and humidity can soften shells and cause them to stick together or deform, which looks like a product failure regardless of the oil’s condition inside.
Stability and the Smell Problem
This is the category’s main field failure.
- Specify peroxide, anisidine and free fatty acid maximums at release.
- Require those parameters across the full stability study, not only at release.
- Require real-time stability in the actual final pack at Indian ambient conditions.
- Require temperature cycling, given warehouse and transit conditions.
- Require sensory assessment at each time point, including opening a capsule.
- Assess the softgel shell condition at each time point.
- Specify the antioxidant system and verify it is effective in your product.
- Choose packaging with oxygen and light barrier.
- Consider blister packaging, since it limits oxygen exposure per unit.
- Run an in-use study for bottles, simulating repeated opening.
- Set shelf life from the oxidation data, not from convention.
Claim Limits
Food framework, and this category is frequently over-claimed.
A supplement cannot claim to treat, cure or prevent any condition. That excludes heart disease claims, cholesterol claims framed as treatment, joint condition claims, and brain or cognitive disease claims.
Heart, brain and eye health claims are the category’s main marketing themes and are physiological claims requiring substantiation and professional advice on permitted wording. Published research on EPA and DHA generally does not substantiate a claim about your product at your dose.
EPA and DHA content claims must be accurate and should state the amounts rather than the oil weight, since consumers and professionals compare on actual EPA and DHA.
The non-vegetarian declaration is mandatory and should not be obscured. Marketing that avoids mentioning the fish source while using neutral or plant-suggestive imagery is misleading.
Sustainability or source claims require documentation from the supply chain if made, and should not be stated on the basis of a supplier’s general assurance.
Pre-Launch Checklist
Confirm before committing.
- Document the source and obtain professional advice on declarations.
- Specify the oil form and the EPA and DHA content per gram with methods.
- Declare EPA and DHA amounts, not only oil weight.
- Specify peroxide, anisidine and free fatty acid maximums.
- Require those values per batch and across stability.
- Specify heavy metal limits per batch.
- Discuss dioxin and PCB testing with your adviser and laboratory.
- Specify the antioxidant system and verify its effectiveness.
- Decide softgel shell material and state vegetarian status accurately.
- Require shell seal integrity testing per batch.
- Require shell condition assessment across stability.
- Require sensory assessment including opening a capsule at each time point.
- Choose packaging with oxygen and light barrier; consider blisters.
- Run an in-use study for bottle formats.
- Set shelf life from the oxidation data.
- Write a claim set excluding heart, cholesterol, joint and cognitive disease claims.
- Obtain substantiation and advice before any health claim.
- Do not obscure the fish source in marketing or imagery.

Frequently Asked Questions
What should the label declare for omega-3?
The EPA and DHA amounts, not only the oil weight. A one-gram fish oil capsule may contain a small or a large proportion of EPA and DHA depending on the oil’s concentration, and consumers and professionals compare on the actual amounts.
Why specify both peroxide and anisidine value?
Because peroxide alone does not describe the oxidation state fully. Anisidine value measures secondary oxidation, and both should be specified with maximums and required per batch and across stability.
What is the main field failure in this category?
Oxidation, which produces the fishy smell and taste consumers complain about. It shows up in sensory terms long before anything else fails, which is why sensory assessment including opening a capsule should be part of every stability time point.
What should I check about softgel shells?
Shell material and vegetarian status, seal integrity testing per batch since leaking is the commonest complaint, and shell condition across stability, since heat and humidity can soften shells and cause sticking or deformation.
Can I make heart or brain health claims?
Not as treatment claims, and other health claims need substantiation at your dose with professional advice on wording. Published research on EPA and DHA generally does not substantiate a claim about your specific product.
