CoQ10 (coenzyme Q10) is a compound your mitochondria use to generate ATP — the energy currency every cell runs on. The heart has the highest concentration of mitochondria in the body and relies on CoQ10 more than almost any other organ. Omega-3s support the cardiovascular system structurally (triglyceride levels, blood vessel flexibility, inflammation management), while CoQ10 supports it energetically at the cellular level. Combining them addresses heart health from two complementary angles in one serving.

CoQ10 production peaks in your twenties and declines steadily from there. By age 40, most people have meaningfully lower CoQ10 than they did a decade earlier. Statin medications — among the most widely prescribed drugs in the world — also significantly suppress CoQ10 synthesis as a side effect. Athletes under heavy training load deplete it faster than sedentary individuals. This formula is specifically recommended for people over 40, those on statins, and performance athletes.

Ubiquinone. This is the oxidized, "energizer" form of CoQ10 — the form your mitochondria use as the primary electron carrier in the energy production process. (Ubiquinol is the reduced, antioxidant form.) If you're looking for the antioxidant-focused CoQ10 form, Nordic Naturals also makes CoQ10 Ubiquinol Sport separately.

CoQ10 has a strong, bitter taste on its own. The soft gel encapsulates it with the fish oil to make it palatable — biting in bypasses that. Swallow both soft gels whole with food for the best experience.

Yes — Nordic Naturals explicitly recommends this formula for performance athletes in addition to those with cardiovascular concerns. Heavy aerobic training places significant demands on cardiac output and mitochondrial energy systems, both of which benefit from the combined omega-3 and CoQ10 support this formula provides.
