Red Yeast Rice Extract
Red yeast rice is an Asian dietary supplement that is made by fermenting red yeast in rice. Red yeast rice has just recently gained recognition in the United States as a cholesterol-lowering agent. Red yeast rice owes its cholesterol-lowering effects to compounds known as statins that are produced as a byproduct of the fermentation process. Red yeast rice extract has a number of heart-healthy benefits. It seems to help reduce total cholesterol levels, lower levels of LDL ("bad") cholesterol, increase levels of HDL ("good") cholesterol, and lower levels of unhealthy fats called triglycerides.

Reference Daily Intakes (RDI)

Reference Daily Intake (RDI) is the daily dietary intake level of a nutrient considered sufficient to meet the requirements of nearly all (97–98%) healthy individuals in each life-stage and gender group. The RDI is used to determine the Recommended Daily Value (RDV) which is printed on food labels in the U.S. and Canada. RDI was formerly called Recommended Dietary Allowance (RDA). RDI is based on the Dietary Reference Intake (DRI).

Retinol is vitamin A. Carotene compounds found in egg yolks, butter and cream, etc. are gradually converted by the body to vitamin A (retinol). A form of vitamin A called retinal is responsible for transmitting light sensation in the retina of the eye. Deficiency of vitamin A leads to night blindness.
Retinol Activity Equivalent (RAE)
The Retinol Activity Equivalent is a relatively new unit for expressing vitamin A activity. One mcg of RAE is equivalent to mcg of all-trans-retinol, 12 mcg of all-trans-beta-carotene, or 24 mcg of other provitamin A carotenoids. These RAE conversion factors are based on recent studies that show that the conversion of provitamin A carotenoids to retinol is only half as great as previously thought.
Rhodiola Rosea
Rhodiola rosea, also known as Roseroot, is a plant in the family Crassulaceae that grows in cold regions of the world. These include much of the Arctic, the mountains of Central Asia, the Rocky Mountains, and mountainous parts of Europe, such as the Alps, Pyrenees, Carpathian Mountains, British Isles, Scandinavia and Iceland. Rhodiola Rosea is known to balance hormonal health, and aid in weight reduction. Rhodiola rosea is very effective for improving mood and alleviating depression. Russian research shows that it improves both physical and mental performance, reduces fatigue, and prevents high altitude sickness.
Riboflavin or Vitamin B2 is a water-soluble vitamin, helps the body release energy from protein, fat, and carbohydrates during metabolism.
