Per Capsule: What Actually Enters Your Mouth

EPA DHA per capsule explained

The only figure the daily maths runs on — with the reading order that makes every conversion automatic.

At a glance

One unit to rule the shelf — why per-capsule wins

Every comparison this cluster runs resolves to a single unit, and this page explains why it must: EPA+DHA per capsule is the only figure that describes what actually enters your mouth — the alternatives each hide something: per-serving figures can sit atop two-or-three-capsule servings, quietly doubling the real cost of any stated payload (the shelf's oldest instrument — the habit's home); per-bottle totals are marketing arithmetic nobody swallows in a sitting; and per-100g panels describe a hundred grams of oil no one will ever scoop, existing mostly to make small numbers look scientific. The benchmark the unit serves: 250mg of the pair daily conditions the everyday heart-maintenance claim (the sentence, the ladder above it) — so the shopping question is always the same: does one capsule state 250mg+ of EPA and DHA combined?

The conversions — turning any layout into the unit

The two translations that decode every label format: per-serving to per-capsule — find the serving size line (often in small print beneath the panel), divide every figure by the capsule count it declares: a '600mg EPA+DHA per serving' label over a two-capsule serving is a 300mg-per-capsule product wearing a doubled headline, and a three-capsule serving makes it 200mg wearing a tripled one (where this trick lives); per-100g to per-capsule — multiply by the capsule's oil weight as a fraction: a 1000mg capsule takes one-tenth of any per-100g figure, a 500mg capsule one-twentieth — the layout most likely to appear when the honest per-capsule number would underwhelm. The reading-order rule that makes both automatic: panel first, serving size second, division third, front-of-pack never (what the two acids each do once counted).

The worked example, and the close

The house rule applied at home as always: Futuro Labs Omega 3's panel in this page's unit — EPA 180mg + DHA 120mg = 300mg of the pair per capsule, serving size one softgel genuinely (division by one — no asterisk), which clears the 250mg everyday condition with 50mg of headroom at ~17p per day across the 90-count bottle (the record, the pence-per-day sum this feeds); and the same read run anywhere else sorts the whole shelf in seconds — concentrates justify their premiums or don't (the percentage behind the milligrams), blends fail by omission, doubled servings surface instantly. Constants: the total-omega line is not the pair (350mg total here includes minor acids; 300mg is the claims number — the gap where marketing lives); gates as ever — pregnancy, nursing or any medication → doctor first per the label (the conversation). EPA and DHA per capsule, closed as the cluster's unit: one number, two conversions, and every bottle on the shelf suddenly speaking the same language.

Frequently asked questions

How much EPA and DHA per capsule do I need?

The everyday benchmark: 250mg of EPA+DHA combined daily holds the heart-maintenance claim — so a capsule stating 250mg+ of the pair meets it at one, which is the whole point of per-capsule arithmetic: Futuro Labs Omega 3 states 300mg (EPA 180 + DHA 120) per single softgel, condition cleared with headroom, no multi-capsule asterisk to divide through.

Why per capsule rather than per serving or per bottle?

Because the other units hide things: per-serving figures can sit atop two-or-three-capsule servings (divide before believing), per-bottle totals are marketing arithmetic nobody swallows at once, and per-100g panels describe oil you'll never scoop. Per capsule is what enters your mouth — the only unit the daily maths runs on.

What if the label only shows per-100g or per-serving figures?

Convert before comparing: per-serving ÷ capsules-per-serving = per capsule; per-100g needs the capsule's oil weight (a 1000mg capsule takes a tenth of the per-100g figure). Any label making you do both conversions to find the pair's sum has chosen its layout for a reason.
