AHCC® - Kinoko® Platinum


AHCC® works as a biological response modifier, which means it turns up the dial on your natural immune response and strengthens your resistance.* It works by increasing the numbers and activity of white blood cells in the body. AHCC® increases the activity of natural killer cells, the body’s first line of defense, by as much as 300-800%.* It boosts populations of macrophages, which engulf and destroy foreign material.* It increases numbers of dendritic cells, which identify immune threats and lead T cells to them.* And it boosts numbers and activity of T cells, which recognize previously encountered immune threats and eliminate them on the spot.*

Oligonol® is a low-molecular-weight, highly absorbable polyphenol made from lychee fruit and green tea. Clinical research has shown that its low molecular weight makes Oligonol® easy to absorb, giving it unparalleled bioavailability.

The effect of Oligonol® on blood circulation was demonstrated in a study showing it effectively raised volunteers’ skin temperature.* It is this ability to improve circulation that underlies its many clinically demonstrated health benefits, such as helping maintain blood lipids already within normal limits, reducing the appearance of eye wrinkles and brown spots, increasing perceived energy during exercise, and decreasing abdominal fat when used in conjunction with a healthy diet and exercise.* No wonder Oligonol® won the prestigious NutraCon “Top Evidence-backed Products of the Year” NutrAward the year it debuted in 2008.

Serotonin (PureBalance™)


5-HTP is an amino acid the body uses to make serotonin, a neurotransmitter that regulates mood, appetite, sleep, and immunity. When levels of 5-HTP rise, so do levels of serotonin. 5-HTP is a better choice for raising serotonin levels than L-tryptophan, because it is converted into serotonin more efficiently and it crosses the blood-brain barrier more effectively.

Rhodiola rosea

Native to Siberia and other cold regions, Rhodiola rosea is an adaptogen, an herb that helps the body adapt to stress.* Rhodiola increases levels of chemicals the brain needs for positive mood, calmness, and motivation, such as serotonin, norepinephrine, and dopamine.* The rhodiola in PureBalance™ Serotonin is standardized to 5% rosavins, the active constituent.

Vitamin D3

Vitamin D is often called the “sunshine vitamin” because the body can synthesize it when sunlight exposure is adequate. However, researchers have discovered that vitamin D insufficiency is surprisingly common, affecting as much as 70 percent of the population. Vitamin D boosts brain chemicals needed for positive mood and modulates immune function.* The D3 form of vitamin D is better absorbed than the D2 form.


Relora is a proprietary blend of two standardized herbal extracts: magnolia and phellodendron bark. It may reduce occasional stress and stress-related overeating by lowering levels of cortisol — a hormone that increases both appetite and fat formation.* A double-blind, placebo-controlled human clinical trial found Relora® helped women prone to stress eating control their weight.*


L-theanine is an amino acid found in green and black tea. It has been shown in human clinical research to create a state of relaxed alertness by increasing the production of alpha brain waves.* One of the best things about L-theanine is that it works fast, reducing stress within one hour.*
