That goal carries a 2000 mg EPA target — four to eight times the EPA targets of the other goals. Since a standard fish oil capsule holds 180 mg of EPA, the engine needs 12 capsules to reach it, and algae oil (100 mg EPA per capsule) needs 20.

It computes the capsule count for each target separately and takes the larger one — the limiting nutrient sets the dose. That guarantees both targets are met, but it also means you overshoot one fatty acid whenever the capsule's EPA:DHA ratio doesn't match your goal's.

Krill is never the cheapest, but it isn't always the most expensive either. At 50 cents a capsule with the weakest EPA/DHA density of the three types (150/90 mg), it's the priciest way to hit the general wellness, heart health, and brain/mood goals. For the inflammation/joint goal, though, algae oil overtakes it: that goal's 2000 mg EPA target forces 20 algae capsules (EPA-thin at only 100 mg each) against 14 krill capsules, so algae's daily cost of $8.00 edges out krill's $7.00 — fish oil stays cheapest at $1.80 across the board.

Algae capsules are DHA-heavy: 300 mg DHA but only 100 mg EPA. The brain goal's 1000 mg DHA target only needs about 4 capsules, but its smaller 500 mg EPA target is the actual limiting nutrient at algae's low EPA density — 500/100 mg works out to 5 capsules, one more than the DHA side alone would suggest — so the engine lands on 5. The inflammation goal flips the mismatch to an extreme: its 2000 mg EPA target forces 20 algae capsules. The gap between capsule ratio and goal ratio is what the capsule count exposes either way.
