Supports respiratory function, glutathione production and detoxification*

N-Acetyl-L-Cysteine (NAC) is a derivative of the dietary amino acid L-cysteine. NAC has a high affinity for lung tissue, which it supports through mucolytic and antioxidant action. Due to its sulfur content, NAC is able to disrupt disulfide bonds within mucus, thinning and easing its expulsion. NAC is a free radical scavenger and thus supports epithelial cell health and healthy cilia activity in the respiratory tract. NAC is also a precursor to the antioxidant glutathione, and supplemental NAC increases tissue levels of glutathione. As fundamental components of the immune system, lymphocytes rely on glutathione to function properly. Tissues enhanced with glutathione support overall antioxidant protection and help to maintain a healthy immune response. A multicenter, randomized, double-blind trial with 262 participants indicated that NAC supplementation for six months supported upper respiratory tract and immune system health. A recent meta-analysis of eight double-blind, placebo-controlled trials provided additional support for NAC's ability to support respiratory tract health.*

Support for bone, breast, prostate, cardiovascular, colon and immune health‡

Vitamin D promotes intestinal calcium and phosphorous absorption, and reduces urinary calcium loss, essential mechanisms for maintaining proper calcium levels in the body and healthy bone composition. Research indicates that it also supports immune cell activity, maintains healthy cell metabolism, and promotes cellular health—including support for breast and prostate tissue, in part by helping to maintain healthy angiogenesis balance. A role for vitamin D in supporting colon health by promoting healthy cellular function has also been suggested. Vitamin D's role in immune health has long been established; vitamin D receptors are found on a number of immune cells, including lymphocytes and macrophages, supporting healthy immune cell activation. Vitamin D also supports cardiovascular function in some individuals.‡

Vitamin D3 naturally supports calcium absorption and retention within bones to promote optimal bone health. Vitamin D3 also supports colon health by promoting healthy cellular function.‡

Zinc plays an important role in supporting the body's natural defense system, as well as nutrient utilization. It is a constituent of over two dozen enzymes involved in digestion and metabolism, including carbonic anhydrase, which is vital to tissue respiration. Zinc is essential for the healthy storage and metabolism of carbohydrates, as well as the absorption and function of B vitamins. Zinc plays a fundamental role in collagen formation and healthy tissue development. This mineral contributes to healthy prostatic function, and is essential for normal fetal and reproductive development.*

Highly absorbable zinc; essential to a wide range of physiological functions, including immune health*

Magnesium (glycinate) is a highly bioavailable magnesium chelate, which supports the metabolism and utilization of carbohydrates, amino acids and fats for energy. Magnesium (glycinate) helps activate enzymes for physiological functions including cardiac health.*

Magnesium activates the enzymes necessary for a number of physiological functions, including neuromuscular contractions, cardiac function, and the regulation of the acid-alkaline balance in the body. In a cross-sectional study involving 210 elderly individuals, optimal magnesium intake was associated with positive mood, lipid metabolism, and lean body mass. Magnesium is necessary for the metabolism of carbohydrates, amino acids and fats, as well as energy production and the utilization of calcium, phosphorus, sodium, and potassium. In a 15-year study involving almost 5,000 young adults, higher intakes of magnesium were associated with healthy cardiovascular function and glucose utilization. Another large cross-sectional study found that magnesium intake was positively associated with bone mineral density in certain subgroups. This vital mineral also helps utilize some vitamins, including vitamin B6, vitamin C, and vitamin E. Magnesium (glycinate) is less likely to cause loose stools than other forms of magnesium.*

Buffered ascorbic acid combines calcium ascorbate, magnesium ascorbate, and potassium ascorbate to create a neutral pH vitamin C. This special form of ascorbic acid lessens possible gastric irritation in sensitive individuals. Vitamin C is an antioxidant and free radical scavenger with a wide range of functions.  It supports the body's defense system by promoting white blood cell function and activity, interferon levels, antibody responses, and secretion of thymic hormones. It is also essential for the formation and maintenance of intercellular ground substance and collagen. Vitamin C aids in the absorption of iron, the formation of red blood cells and conversion of folic acid to active folinic acid. It also maintains healthy mast cell function and supports lymphocyte formation. Vitamin C is also required for the synthesis of carnitine and steroids.*
