Testa is for the buyer who wants maximum DHA without sacrificing EPA entirely. It carries 325 mg DHA — the highest here among picks that still include EPA — plus 150 mg EPA, in absorbable re-esterified triglyceride (rTG) form, and a 60-count bottle is a genuine two-month supply at one softgel a day. It's stated free of mercury, heavy metals, PCBs and microplastics, and it's Kosher and non-GMO. The honest caveats keep it at #4 rather than higher. It's a lighter-presence import brand without the US shelf recognition of Nordic Naturals, and — importantly — some Testa variants list carrageenan in the shell, so carrageenan-avoiders should confirm the exact SKU before buying. Neither undercuts the formula: a DHA-forward, EPA-included, rTG-form, low-contaminant oil is a strong combination. For the most DHA you can get while still keeping a complete omega-3, it's the pick.

Read the complete Algae Oil Omega-3 guide →325 mg DHA — the highest in this ranking among picks that still carry EPA — plus 150 mg EPA, in one softgel. A DHA-forward but genuinely complete omega-3, the niche it owns: more DHA than the balanced picks above it, without dropping EPA to zero like the DHA-only products below.
Re-esterified triglyceride (rTG) form — the most bioavailable family per Dyerberg 2010 — which is a genuine absorption strength and stated explicitly. Held below the top because some Testa variants list carrageenan in the shell, so it can't claim the reliably additive-light, carrageenan-free delivery that #2 and #3 do.
Stated free of mercury, heavy metals, PCBs and microplastics — the marine-contaminant freedom that's a core reason to choose algae over fish — plus Kosher and non-GMO. Strong on contaminants; a touch below the per-batch-potency picks because the listing doesn't publish a specific oxidation/TOTOX or per-batch potency figure.
Fair value: a single-softgel serving means the 60-count bottle is a true two-month supply, better per day than a two-softgel 60-count. Mid-pack on price overall — Calgee's 120-count (#3) wins raw cost-per-day — but reasonable for the highest-DHA-with-EPA, rTG-form profile.
Fish-free algae sourcing and a published 325/150 DHA:EPA split are both in its favor on this axis. Marked slightly down because the carrageenan content varies by SKU rather than being clearly resolved on one consistent label — a small label-clarity issue for carrageenan-sensitive buyers.
“Highest-DHA vegan algae oil that still includes EPA.”
Accurate within our ranking: at 325 mg DHA it's the highest of the picks that still carry meaningful EPA (150 mg). The DHA-only products (Minami #8 at 500 mg) go higher on DHA but drop EPA, so Testa's specific claim — highest DHA while keeping EPA — holds.
“Re-esterified triglyceride (rTG) form for absorption.”
Stated on the listing, and supported by Dyerberg 2010 (PMID 20638827), which found rTG the most bioavailable marine omega-3 form, well above ethyl ester. The better-absorbed-form claim is sound.
“Free of mercury, heavy metals, PCBs and microplastics.”
Stated on the listing and credible by source — algae grown in controlled conditions avoids the marine-contaminant load of caught fish. Note this is a contaminant-freedom claim, not a published oxidation/TOTOX number, which the listing doesn't provide.
Testa's 325 mg DHA is the highest in this ranking among products that still carry EPA. That's a real position: the balanced picks above it (300-390 mg DHA) carry more EPA, while the DHA-only picks below it (Minami #8 at 500 mg) carry none. If your priority is DHA — the omega-3 best studied for cognition and vision — but you still want EPA on the label, Testa is the bottle that threads that needle.
Testa is one of the few here to state re-esterified triglyceride (rTG) form, the most bioavailable marine omega-3 family in Dyerberg 2010. Combined with a low-contaminant profile (free of mercury, heavy metals, PCBs and microplastics), the oil quality itself is excellent — the DHA and EPA on the label are well-absorbed and clean.
The one practical catch: some Testa variants list carrageenan in the softgel shell, so unlike Sports Research (#2) or Calgee (#3), it can't be assumed carrageenan-free. If you avoid carrageenan, confirm the exact variant before ordering. It's purely a shell-additive issue — it doesn't touch the oil — but it's the reason carrageenan-sensitive buyers should look at the specific product page, and part of why Testa sits at #4 rather than higher.
Testa fills a specific and useful slot: the most DHA in this ranking — 325 mg — among picks that still carry real EPA (150 mg), in absorbable re-esterified triglyceride form, stated free of mercury, heavy metals, PCBs and microplastics, Kosher and non-GMO, with a 60-count bottle lasting a genuine two months. The oil itself is excellent: DHA-forward, EPA-included, well-absorbed and clean. It lands at #4 on honest caveats rather than formula. It's a lighter-presence import brand without Nordic Naturals' shelf recognition, and some Testa variants list carrageenan in the shell, so carrageenan-avoiders must confirm the exact SKU. If you want the highest balanced dose from the most trusted brand, #1 is the call; if you want a guaranteed carrageenan-free one-a-day, #2 or #3 deliver it. But for the buyer who wants to push DHA as high as possible while still keeping a complete omega-3 in a well-absorbed rTG form, Testa is the pick.

See it on the list →Best verified value — 300/150 per softgel, a 120-count bottle, and per-batch Eurofins testing, with a reliably carrageenan-free shell. Pick this if cost-per-day and a guaranteed additive-light shell matter.
See it on the list →The DHA maximizer if you don't need EPA — 500 mg pure DHA with verified-low oxidation, but DHA-only. Choose this only if DHA alone is the goal.
See it on the list →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.
600 mg/day DHA from algal-oil capsules raised plasma and erythrocyte DHA as much as DHA from cooked salmon — the basis for algal-oil DHA being nutritionally equivalent to the DHA in fish.
