The Science of Supplements


The scientific studies described on this website were conducted by independent researchers, and presented for educational purpose only. The views expressed in the studies do not reflect those of the owner of this website. The subject products of the studies may be classified as dietary supplements in the United States. Those dietary supplements are not intended to diagnose, treat, cure or prevent any disease.

Committed to Science

Since its inception in 1972, Wakunaga of America has embraced the belief that only high-quality, scientifically-backed products should be presented to the marketplace. Our Aged Garlic Extract has been the subject of more than 900 scientific papers. Many of these are peer-reviewed double-blind, randomized, placebo-controlled clinical trials, considered to be the “gold standard” among the scientific community.

A double-blind, randomized, placebo-controlled clinical trial is a medical study involving human participants. The participants are randomly assigned to either one or more treatment groups or to a placebo group. A placebo is an inactive substance (often a sugar pill) given to a patient in place of the active treatment. During a double-blind trial, neither the participants nor the researchers know who’s getting treatment or who is getting a placebo. In that way, researchers can compare how effective the active treatment is against the placebo; without any bias.

Proven Benefits Backed by Science

Through the years, Aged Garlic Extract has been found to provide key cardiovascular benefits in numerous double-blind, randomized, placebo-controlled clinical trials. These findings include:  lowering blood pressure and cholesterol, slowing the progression of atherosclerosis by reducing the buildup of plaque and calcium deposits, and enhancing circulation. Other studies show that Aged Garlic Extract may play a role in immunity, blood sugar control, and liver support, either alone or when combined with other targeted nutrients.

Wakunaga carries this commitment to research and the use of scientific evidence through to all of our products. For instance, double-blind, randomized, placebo-controlled clinical trials show that the three probiotic strains used in Wakunaga’s probiotic line—Lactobacillus gasseri KS-13, Bifidobacterium bifidum G9-1, and Bifidobacterium longum MM-2—favorably impact the microbial balance in the intestines, promote good digestion, enhance immune function, and may help ease the symptoms of some chronic digestive disorders. Other trials report that the plant sterols and sterolins found in some of our other supplements can strengthen the body’s immune system and lower cholesterol.

As a result of Wakunaga’s dedication to science and commitment to quality, consumers can be assured that the supplements we make are thoroughly vetted for safety and efficacy. It’s this unwavering commitment that forms a key cornerstone of Wakunaga’s pledge to excellence.
