Well known as a venerated culinary herb, garlic (Allium sativum) has been used for centuries to support health and longevity.
It has been found in Egyptian pyramids, ancient Greek temples, medical texts from a variety of cultures, and even on
Hippocrates’ list of health-promoting compounds. Garlic is used widely today to support cardiovascular health, antioxidant
activity, and immune function.*[2,3]
Organosulfur Compounds and Antioxidant Activity Many of the health-promoting benefits of garlic are attributed
to its array of sulfur-containing compounds. Organosulfur compounds from whole garlic fall into two classes: gammaglutamylcysteines
and cysteine sulfoxides. Crushing, chopping, and processing garlic results in production of organosulfur
compounds that fall into one of four main chemical classes—alliin, allicin, allyl cysteine, and allyl disulfide. Several of these
compounds have been studied for their compelling effect on antioxidant activity. Alliin (allylcysteine sulfoxide) was found
to scavenge superoxide, while allicin (a thiosulfinate) suppressed its formation. Hydroxyl radicals were scavenged by alliin,
allyl cysteine, and allyl disulfide; allyl disulfide was found to be a lipid peroxidation terminator as well. Best Garlic contains
standardized amounts of gamma-glutamylcysteines, alliin, allicin, thiosulfinates, and sulfur.*
Glutathione (gamma-glutamyl-cysteinyl-glycine) is a well-researched component of vital antioxidant systems in the body.
Glutathione is also recognized for its role in regulation of cellular events such as DNA and protein synthesis, gene expression,
cell-life cycle regulation, signal transduction, cytokine production, and immune response. Gamma-glutamylcysteine
(GGC), an endogenously produced precursor to glutathione, has been found to efficiently detoxify hydrogen peroxide and
superoxide anion in the mitochondria. Research suggests that GGC may assume the neuroprotective and antioxidant
functions of glutathione as needed.*
Cardiovascular Health Numerous studies suggest that garlic has a positive effect on plasma lipids, normal fibrinolytic
and platelet activity, and the maintenance of blood pressure and blood glucose already within the normal range. A metaanalysis
of 26 studies showed that garlic supported total cholesterol and triglyceride metabolism with a significance of p
= 0.001 and p < 0.001 respectively. Studies suggest that garlic may play a cardioprotective role in maintaining normal
levels of oxidized low-density lipoprotein (LDL), nitric oxide production, healthy cytokine balance, and normal endothelial
function as well.[10,11] Garlic-derived organosulfur compounds are converted by erythrocytes into hydrogen sulfide, which in
turn supports vasodilation, vascular smooth muscle relaxation, and overall cardiovascular health. Garlic supplementation
had a significant impact on cardiovascular health parameters in select subjects during a 12-week, randomized, single-blind
Immune Support In the mid-1900s, Louis Pasteur noted garlic’s ability to support immune function, and it is known to
have been used for immune support during World War I. Ongoing research reveals a broad range of immune-supportive
properties associated with garlic, especially its allicin component.[4,14] Allicin appears to react with the thiol groups of a variety
of enzymes (including alcohol dehydrogenase, thioredoxin reductase, and RNA polymerase), which, in turn, supports normal
microbial balance in the body. A double-blind placebo-controlled study of 146 volunteers suggests that stabilized allicin
compound is significantly effective in supporting and maintaining healthy immune function.*
Modern-day research appears to confirm the health-promoting properties of garlic that ancient Egyptians, Greeks, Chinese,
and Indian cultures embraced for so long. Best Garlic is an ultra-concentrated garlic formula with standardized levels of
several organosulfur compounds designed to support antioxidant, cardiovascular, and immune systems.*
