Use this omega 3 buying guide to compare EPA and DHA amounts, purity testing, and serving size before you pick a fish oil supplement.
Quick answer
Choose an omega 3 supplement by reading the EPA and DHA amounts per serving first, then confirm purity testing and serving size. If you want a high-potency fish oil with disclosed EPA and DHA, Olympian Labs Omega 3+ is a straightforward option to compare against others.
Why total fish oil milligrams can mislead you
A bottle that says 1,000 mg fish oil does not tell you how much EPA and DHA you actually get. Those two omega-3 fatty acids are the ones most people are shopping for, so compare products by their EPA and DHA amounts per serving, not by the total oil weight.
This is also where serving size matters. If a product requires two softgels per serving, the EPA and DHA numbers apply to that pair, not to a single capsule. Check how many servings the bottle actually contains before you compare cost or convenience.
Purity testing: what to look for on the label
Fish oil can carry environmental contaminants, so a credible label should say the oil is purified or tested for things like PCBs and mercury. Molecular distillation is one common purification step; testing claims are only useful if they are stated clearly.
Be cautious with vague phrases such as “pharmaceutical grade” when they appear alone. Treat them as marketing language unless the label also explains the testing or distillation process behind them.
When a high-potency formula is worth it — and when it isn't
Higher EPA and DHA per serving can mean fewer softgels to reach your target, which helps if you dislike taking several capsules a day. The trade-off is that high-potency products often cost more per bottle and may not suit anyone who prefers a lower, food-first approach.
If you already eat oily fish regularly, you may not need a high-potency supplement at all. Match the product to your diet and your willingness to take it consistently, not to the biggest number on the label.
Decision rules for choosing an omega 3 supplement
- Start with EPA and DHA per serving: Find the EPA and DHA amounts on the supplement facts panel and note the serving size they refer to. If a label only lists total fish oil, treat it as incomplete for comparison. Write down the EPA and DHA numbers before you compare prices.
- Check the purity statement: Look for explicit mention of purification or testing for contaminants such as PCBs and mercury. If the label only says “pharmaceutical grade” without explaining testing, ask for details or choose a product that states its process.
- Match serving size to your routine: Count how many softgels make one serving and how many servings the bottle contains. A high-potency product that needs two softgels per serving may still be convenient if it replaces four lower-potency capsules. Compare cost per serving, not cost per bottle.
- Decide whether you need high potency: If you rarely eat oily fish and want a simple daily supplement, a formula with disclosed EPA and DHA like Omega 3+ is reasonable to consider. If you eat oily fish several times a week, a lower-potency product may be enough.
Product facts to compare
- Omega 3+: Omega 3+ provides 530 mg EPA and 340 mg DHA per serving from cold-water anchovies, mackerel, and sardines. The disclosed EPA and DHA amounts let you compare it directly with other fish oils instead of guessing from total oil weight.
Omega 3+ - Omega 3+: The fish oil is molecularly distilled and tested for environmental contaminants such as PCBs and mercury. That gives you a concrete purity checkpoint to look for when comparing labels.
