Octacosanol is a waxy substance naturally present in some plant oils and is the primary component of the sugar cane extract called policosanol.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Preliminary studies have suggested that octacosanol improves endurance, reaction time, and other measures of exercise capacity.
Wheat germ oil, which contains a waxy substance known as octacosanol, has been investigated as an ergogenic agent. Preliminary studies have suggested that octacosanol improves endurance, reaction time, and other measures of exercise capacity.1 In another preliminary trial, supplementation with 1 mg per day of octacosanol for eight weeks improved grip strength and visual reaction time, but it had no effect on chest strength, auditory reaction time, or endurance.2
When octacosanol is taken as part of policosanol, 5–10 mg of policosanol is taken twice each day with meals. For exercise performance, 1 mg per day of octacosanol has been used.
Octacosanol is a waxy substance found in vegetable oils and sugar cane (Saccharum officinarum). Another compound, called policosanol, contains a large amount of octacosanol, along with several similar compounds.
Because octacosanol is not an essential bodily constituent, deficiencies do not occur.
