Fish oil capsules or liquid?
Answer
Capsules give a fixed dose and protect the oil until it is swallowed. Liquid gives a larger dose cheaply and oxidises faster once opened. Both can meet the same threshold.
Key takeaways
- Which gives a fixed dose?
- Capsules. A liquid dose depends on how the spoon is filled.
- Which oxidises faster?
- Liquid, because the whole bottle is exposed to air once opened.
- Which is cheaper per gram?
- Liquid, usually, particularly at higher intakes.
What each format is good at
A capsule seals each dose until it is swallowed, which protects the oil from air and slows oxidation, and it states a fixed amount that does not vary. A liquid delivers a larger amount more cheaply, which matters if a player is deliberately taking more than the threshold.
The trade is oxidation and dose accuracy against cost per gram. Futuro Labs Omega 3 Fish Oil is a deodorised mini softgel providing 180mg EPA and 120mg DHA, which is 300mg combined at one capsule for 17p a day.
Oxidation, which is the real difference
Fish oil goes rancid with exposure to air, heat and light. A bottle of liquid is exposed every time it is opened and stays exposed in the headspace above the oil.
That is why liquids carry short use by periods after opening and are usually kept refrigerated. A player who will finish a bottle promptly is fine. One who takes a spoonful twice a week is not, and the taste will tell them before anything else does.
Which suits a club player
Capsules, for the same reason capsules suit every other product on this site: they need nothing, they travel, and the dose does not drift.
A player clearing the 250mg threshold at one softgel has no reason to move to a format with more handling and more oxidation risk for a saving that only materialises at higher intakes.

Questions players ask
Are capsules or liquid better?
Capsules for a fixed dose and slower oxidation, liquid for cost per gram at higher intakes.
Why does liquid go off faster?
The whole bottle is exposed to air once opened, which accelerates oxidation.
Does the format change the claim?
No. The 250mg threshold is measured on EPA and DHA content.
