How these numbers are read
- Bioavailability is the share of the dose that reaches your bloodstream — the single most useful number when choosing a form.
- Safety rating reflects tolerance at normal doses, not toxicity risk.
- Cost is per month at the typical daily dose, so a cheaper form taken at double the dose is not cheaper.
- Evidence level A means the form itself was studied, not just the parent compound.

Common questions
Which is better, DHA or Fish Oil (EPA/DHA)?
DHA absorbs better — 85% against 85%. Absorption decides how much of the dose actually reaches you, so it usually matters more than the milligrams printed on the label.
What is the difference between DHA and Fish Oil (EPA/DHA)?
Both deliver the same active compound. They differ in how well the body takes them up, how they are tolerated and what a month costs: $50 against $25.
Can you take DHA and Fish Oil (EPA/DHA) together?
You can, but there is rarely a reason to. Two forms of the same compound stack the same active dose, so the usual approach is to pick the better absorbed one and dose it properly.
