🧪 Formulation Notes

Omega 4X SX-7 Black Onyx is an advanced, ultra-pure and high-potency fish oil formula designed specifically for hardcore athletes.

With 1,500mg of fish oil in each serving, Omega 4X SX-7 Black Onyx supplies 1,200mg of omega-3 fatty acids - that’s an 80% concentration, one of the highest potencies available. Each capsule delivers an incredible four times the omega-3 fatty acids of regular fish oil products. This includes high doses of the key omega-3 fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA).

Featuring a Potent Dose of DPA Omega 4X SX-7 Black Onyx also contains 150mg of docosapentaenoic acid (DPA) and other omega-3 fatty acids.

And for a complete formula, 1,000 IU of vitamin D is included to help meet your daily requirements.

Meanwhile, super-critical purification technology refines the precious oil to remove unwanted impurities, such as mercury, cadmium, lead and PCBs – harmful impurities you definitely don’t want in your fish oil product.
