Testa Omega-3 DHA + EPA Review

That's the whole point of this pick. It carries 300 mg DHA — the highest of any product in our ranking that still includes real EPA — plus 150 mg EPA, in a single softgel. Plenty of high-DHA algae oils drop EPA to zero to push the DHA number up (Garden of Life Minami at #8 is 500 mg DHA but EPA-free). Testa lets you maximize DHA without going DHA-only, so you still get a complete omega-3. If you want the DHA-forward profile but refuse to give up EPA entirely, this is the one.

It's the better-absorbed molecular form of omega-3. Marine oils come as triglyceride, re-esterified triglyceride (rTG), or the cheaper ethyl ester — and Dyerberg 2010 (PMID 20638827) found rTG the most bioavailable, well above ethyl ester. Testa is in rTG form, so the 300 mg DHA and 150 mg EPA on the label are in the form your body takes up most efficiently. Between two otherwise comparable algae oils, the rTG one is the better-absorbed choice, and Testa is one of the few here that states rTG explicitly.

Not necessarily — and this is the one caveat to check. Some Testa SKUs list carrageenan in the shell, so the product is NOT reliably carrageenan-free the way Sports Research (#1) or Calgee (#2) are. If a carrageenan-free softgel is a hard requirement for you, confirm the specific variant you're buying before you order, because it can vary between Testa products. If carrageenan isn't a concern, this doesn't affect the oil quality at all — it's purely a shell-additive preference.

Strong on this front. Testa states the oil is free of mercury, heavy metals, PCBs and microplastics — the marine-contaminant load that's the main reason people leave fish oil — and it's Kosher and non-GMO. Because it's algae grown in controlled conditions rather than caught at sea, that clean-contaminant claim is credible by source. It doesn't publish a specific oxidation/TOTOX number on the listing, so on purity it scores well but a touch below the per-batch-potency picks; on heavy-metal freedom it's exactly what you want.

It's a genuine two-month supply: 60 softgels at one a day. That helps the value math — a 60-count bottle that lasts 60 days (because the serving is a single softgel) is more economical per day than a 60-count bottle whose serving is two softgels and lasts only 30. Testa sits mid-pack on price among our picks: not the cheapest (Calgee's 120-count wins on raw cost-per-day), but fair for the highest-DHA-with-EPA profile in rTG form. You're paying a small premium for the DHA-forward, well-absorbed formula.

In 72 volunteers, re-esterified triglyceride (rTG) form gave the highest omega-3 bioavailability (124% vs fish-oil triglyceride) while ethyl ester was lowest (~73%) — direct support for Testa's rTG-form absorption advantage.

In 176 healthy young adults, 1.16 g/day DHA for 6 months improved episodic memory and reaction time versus placebo — the cognitive evidence that makes a DHA-forward oil like Testa worthwhile.
