Mega 3/6/9 blends fish, flax, and borage oils for broad EFA support, while Mega-DHA Premium Fish Oil concentrates DHA for brain and eye health. Here's how to choose.

Quick answer

Choose Mega 3/6/9 if you want a broad blend of fish, flax, and borage oils to support skin, joints, and cardiovascular function. Choose Mega-DHA Premium Fish Oil if your priority is a concentrated DHA source for eye and brain health.

What separates these two omega supplements

The core difference is scope versus focus. Mega 3/6/9 combines three oil sources—fish, flax, and borage—to deliver a wider spread of essential fatty acids, including 645 mg of omega-9 from flax seed oil and borage oil. Mega-DHA Premium Fish Oil is a single-source fish oil built around DHA, an essential fatty acid the catalog ties to eye and brain support and mental and visual function.

That means the decision is not about which product is stronger. It is about whether you want a multi-oil blend for general EFA coverage or a DHA-centered fish oil for a specific health goal.

The trade-off: breadth versus DHA concentration

Mega 3/6/9 gives you omega-3, omega-6, and omega-9 in one softgel, which suits people who prefer a single daily supplement over stacking separate oils. The trade-off is that its DHA content is not stated in the supplied catalog facts, so you cannot compare it head-to-head with Mega-DHA on DHA milligrams.

Mega-DHA Premium Fish Oil is positioned as a premier fish oil source of DHA, but it does not include the flax and borage oils that make Mega 3/6/9 a broader blend. If you specifically want omega-9 or plant-based omega-3 sources alongside fish oil, Mega 3/6/9 covers that; Mega-DHA does not.

Quality testing and daily use

Both products come from a brand that tests its oils for impurities. Mega 3/6/9 is tested for PCBs, heavy metals including mercury, and other impurities, and it has a lime flavor that the catalog describes as pleasant to take. Mega-DHA Premium Fish Oil is also a fish oil, so the same category-level purity expectations apply, though the catalog does not list its exact testing panel.

Daily use differs slightly: adults take 3 softgels of Mega 3/6/9 per day and should not chew them. The catalog instructions for Mega-DHA Premium Fish Oil are not fully listed, so check the label for its specific daily amount before starting.

Key trade-offs to weigh

Omega spectrum: Mega 3/6/9 covers omega-3, omega-6, and omega-9 from three oil sources; Mega-DHA Premium Fish Oil focuses on DHA from fish oil. Pick the broader blend if you want general EFA support; pick the DHA product if brain and eye health is the goal.
DHA amount: Mega-DHA Premium Fish Oil is positioned as a premier DHA source, but the catalog does not state its DHA milligrams. Mega 3/6/9 also does not list DHA milligrams in the supplied facts. Compare actual DHA amounts on the Supplement Facts labels if DHA dosage matters to you.
Daily routine: Mega 3/6/9 requires 3 softgels daily for adults and should not be chewed. Mega-DHA Premium Fish Oil dosing is not fully listed in the catalog. Check the Mega-DHA label for its daily softgel count before switching.

Mega 3/6/9
