What changed this quarter
Six brands moved. The methodology did not.
We re-tested 22 fish oil products available in India during January–March 2026. Six brands recorded materially different TOTOX scores compared to our 2024 baseline — four improved, two declined. Sixteen brands held steady within ±3 TOTOX units, which is within normal batch-to-batch variance.
No new brands have been added to the panel this cycle. If you were happy with your brand's previous ranking and it isn't listed in the movers section, its score was stable.
All testing uses the same protocol as our 2024 baseline review: TOTOX = (2 × peroxide value) + anisidine value. Samples were purchased retail in Mumbai, Delhi, and Bengaluru and stored per label instructions before testing. No manufacturer samples accepted. Full protocol: nakedcompound.in/pages/methodology
The brands that moved
The following eight brands recorded a TOTOX delta of ±5 or greater versus their 2024 score. That threshold is our editorial cut-off for a "material" change worth reporting.
Moved up (score improved)
The single biggest mover this cycle. The brand reformulated its nitrogen-flushed packaging in late 2025 — Q1 batches reflect that change. Peroxide value dropped from 7.4 to 3.9 meq/kg.
Peroxide value fell meaningfully; anisidine held flat. Consistent with a cold-chain improvement rather than formula change — the improvement may not hold across summer batches.
Moved from our "marginal" band into "acceptable." Anisidine dropped sharply, suggesting fresher raw material sourcing. Still not a top-tier score, but no longer in the fail band.
Remained in the pass band and improved. Higher concentration products tend to oxidise faster per-capsule, so this result is relatively strong for the 1250mg EPA+DHA category.
Moved down (score worsened)
The most concerning mover this cycle. Anisidine nearly doubled, indicating that rancidity is progressing in the chain — not just at source. We're retesting a second batch before updating the full review score. Recommend avoiding until confirmed.
Moved from our "excellent" band to "acceptable." Peroxide rose significantly; anisidine held. Possibly a storage or transit issue rather than a formula problem. The score is still below our fail threshold — this is a flag, not a disqualification.
Full leaderboard — all 22 brands
Scores below are from Q1 2026 batches. The GOED voluntary standard sets a TOTOX ceiling of 26 meq/kg; we use a stricter internal threshold of 20 for a "pass" rating, reflecting India's ambient storage conditions.

Why India's climate is a structural problem
Fish oil capsules are one of the most oxidation-sensitive supplements on the market. The oxidation rate roughly doubles with every 10°C rise in temperature — which means a bottle sitting in a Mumbai warehouse at 38°C in April will deteriorate at nearly four times the rate of the same batch sitting in a 10°C European distribution centre.
This isn't a reason to avoid fish oil in India — it's a reason to buy from brands that account for it. Nitrogen flushing, amber UV-blocking bottles, and refrigerated warehousing all matter. When a brand does none of these, a "fresh" batch at manufacture can arrive as a marginal product after two months on a shelf in Chennai.
The practical implication: check the manufacture date, not just the expiry. A 24-month-shelf-life product manufactured 18 months ago and stored warm may be worse than a product manufactured 2 months ago with a 12-month shelf life.
Check the manufacture date printed on the bottom or back of your bottle. If it's more than 12 months old and the product wasn't refrigerated in transit, consider switching to a fresh batch — even if the expiry date is distant. Rancidity runs on a clock that doesn't pause at the "best before" stamp.
TOTOX explained — for new readers
If this is your first time reading our fish oil reviews, here's the short version. Fish oil oxidises in two stages. Primary oxidation produces peroxides — measured as the peroxide value (PV). These peroxides then break down further into aldehydes and other secondary oxidation products — measured as the anisidine value (AV).
TOTOX combines both: TOTOX = (2 × PV) + AV. The weighting on PV reflects the fact that primary oxidation is the precursor to all downstream degradation. A product with a low PV but very high AV is one that has already passed through the worst of its oxidation — the damage is done. A product with a high PV but low AV is actively deteriorating and will get worse in your cabinet.
Neither scenario is good. TOTOX catches both.
