Effects of a Supplement Derived From Palm Oil on Cholesterol Levels and Chinese Red Yeast Rice in the Blood

Withdrawn before enrolling · Phase 2/Phase 3 · Has a placebo group

Conditions studied: Cholesterol Lowering

In brief

The purpose of this study is to determine the effects of a palm-oil derived tocotrienol (TRF) supplement or Chinese red yeast rice (CRYR) individually and in combination on blood cholesterol, and particularly LDL cholesterol, in individuals who have either elevated or normal cholesterol levels. Tocotrienols are members of the vitamin E family, and are found in barley, oats, rye, coconut oil and rice bran oil, but the richest source of tocotrienols is palm oil. Certain of these tocotrienols have been shown to be effective in lowering LDL (or 'bad') cholesterol, with no adverse effects on the HDL (or 'good') cholesterol.
