Coenzyme Q10, or ubiquinone, is present in every cell of the body and plays a central role in cellular energy production within the mitochondria. Discovered in 1957 by biochemist Frederick Crane, the body’s natural CoQ10 production declines progressively with age, which is why supplementation draws growing interest, particularly after age 40.

CoQ10 acts as an electron carrier in the mitochondrial respiratory chain, essential for producing ATP, the cell’s energy currency. The heart, brain, liver and kidneys — the body’s most energy-demanding organs — are naturally richest in CoQ10 and most sensitive to declining levels, which is why CoQ10 support is often recommended for these organs, including normal heart muscle function.

Endogenous CoQ10 production peaks around age 20 and declines thereafter — by 40, heart CoQ10 levels are already down roughly 30% from their peak. Statins, widely prescribed for cholesterol, inhibit an enzyme also involved in the body’s CoQ10 production, which is why many healthcare professionals recommend CoQ10 supplementation for people on statins — consult your doctor if this applies to you.

Take 1 capsule a day with a fat-containing meal, since CoQ10 is fat-soluble and absorption improves significantly with dietary fat. A bottle of 60 capsules gives 2 months; a continuous course of at least 8–12 weeks is recommended for optimal tissue levels.

Not a substitute for a varied, balanced diet. Consult a healthcare professional before use, particularly if taking medication. Store in a cool, dry place away from heat and direct light.

What is the difference between ubiquinone and ubiquinol?

Ubiquinone (oxidised) and ubiquinol (reduced) are the two forms of CoQ10 in the body. NOW Foods uses ubiquinone, the most studied and stable form; the body naturally converts it to ubiquinol as needed.

How should I take CoQ10 200mg?

Take 1 capsule a day with a fat-containing meal. A bottle gives a 2-month course; a minimum continuous 8–12 week course is recommended for best results.
