HK$ 60.00
iHerb
Immune Support & Synergistic Antioxidants Dietary Supplement Non-GMODihydroquercetin-3-rhamnoside (D-3-R) is a flavonoid and potent water soluble antioxidant that is synergistic with Vitamin C. Unlike many flavonoids, D-3-R is very bioavailable. Professor Szent-Gyorgyi, the recipient of the Nobel Prize for Vitamin C, categorized flavonoids such as D-3-R as "vitamin P," making Vitamin C more biologically active and available.

Life Extension Buffered Vitamin C Powder 16 oz (454 g)
HK$ 186.00
iHerb
Foundation for Longer Life Vitamin C for Sensitive Stomachs Dietary Supplement Vitamin C, or ascorbic acid, is a white, crystalline, water-soluble substance found in citrus fruits. As an antioxidant, vitamin C scavenges free radicals in the body and protects tissues from oxidative stress. Vitamin C also promotes the absorption of iron, while preventing its oxidation. Vitamin C is a vital cofactor to the formation of collagen, the connective tissue that supports arterial walls, skin, bones, and teeth. A major immune-supporting activity of vitamin C is boosting glutathione levels in human lymphocytes, cells that make up about 25% of all white cells in the blood. More vitamin C is contained in the adrenal glands than any other organ in the body and is required at higher levels during times of stress. Physical stresses on the body such as ingestion of heavy metals, cigarette smoking, immune impairment, extreme temperatures, and chronic use of certain medications such as aspirin also signal the need for increased intake of vitamin C. Vitamin C Powder contains four buffering minerals, in addition to ascorbic acid. When mixed with water, this product produces a reduced-acid solution that is non-irritating to the stomach and intestinal lining. The minerals also make it a more pleasant-tasting and healthful drink. The substances used in this product make it effervesce for a short while when it is mixed with water.

Life Extension Standardized Cistanche 30 Veggie Caps
HK$ 119.00
iHerb
Immune Senescence Protection Dietary Supplement Standardized Cistanche provides powerful support against immune senescence. Scientists have discovered that the echinacoside compound found in Cistanche plant extract stimulates the development of naive T cells and leads to a lower amount of memory T cells, thereby creating a more balanced immune response. Cistanche also increases natural killer (NK) cell activity—resulting in a 15% life span increase in animal research. A 12-week human study of a dietary supplement containing standardized Cistanche resulted in impressive gains in immune factors after supplementation. Subjects had significant improvements, including an 11.7% increase in natural killer (NK) cell activity and a 20.2% improvement in the ratio of CD4 to CD8 cells. An increased CD4/CD8 ratio is indicative of healthy, youthful immune function. For those seeking the effects of Cistanche only, Life Extension has created a standalone Standardized Cistanche that contains the same echinacosides as in the Immune Senescence Protection Formula.

Life Extension Super Alpha-Lipoic Acid With Biotin 250 mg 60 Capsules
HK$ 219.00
iHerb
For Longer Life The Universal Antioxidant Dietary Supplement Alpha-lipoic acid is an antioxidant used in Europe to promote liver and nerve health, and confer protective benefits against oxidative processes. Alpha-lipoic acid has been called the “universal” antioxidant because it boosts glutathione levels in cells already within a normal range and has potent antioxidant actions. Research has strongly implicated cellular oxidative damage caused by free radicals as a cause of many degenerative problems. What makes alpha-lipoic acid so effective as an antioxidant is its ability to quench free radicals in both aqueous and lipid environments. This means that the antioxidant activity of alpha-lipoic acid is working in the extra-cellular fluid and also within the cell. It also has metal chelating ability, helping the body rid itself of accumulated ingested toxins. Alpha-lipoic acid also is a cofactor for some of the key enzymes (alpha keto acid dehydrogenases) involved in generating energy from food and oxygen in mitochondria and thus plays a critical role in energy production within the cell’s mitochondria. One of the most beneficial effects of alpha-lipoic acid is its ability to regenerate other essential antioxidants such as vitamins C and E, coenzyme Q10, and glutathione, and the activities of superoxide dismutase (SOD) and glutathione peroxidase (GPx). The evidence is especially strong for the ability of DHLA (dihydrolipoic acid, a reduced form of alpha-lipoic acid) to recycle vitamin E. This is apparently achieved directly by quenching tocopherol radicals or indirectly by reducing vitamin C or increasing the levels of ubiquinol (a derivative of CoQ10) and glutathione, that, in turn, helps regenerate tissue levels of vitamin E. In clinical studies to date with alpha-lipoic acid, there have been no reported serious adverse side effects, even at high doses. Among the mild, reversible side effects found in some patients have been allergic skin reactions and possible hypoglycemia in diabetics. Please note that the R-lipoic acid provides a more biologically active form of lipoic acid than alpha-lipoic acid at only a slightly higher cost.
