Targeted Antioxidant System™ (TAS-a™) is a 3rd-generation combination of efficient sources of intracellular cysteine-rate limiting components used for intracellular reassembly of the tripeptide glutathione (GSH). TAS-a™ includes staged antioxidant resources that are designed to simultaneously maintain: GSH's antioxidant activity (refurbish GSSG to GSH) and GSH levels via reductions in the extracellular escape of GSSG. Intracellular GSH promotes erythrocyte (~10µ) flexibility which is required both for their flow though typically smaller diameter capillaries (~5-8µ) and consequent oxygen and nutritional servicing of deeper and peripheral tissues.

TAS-a™ is a dietary supplement targeted at both maintaining intracellular glutathione (GSH) antioxidant levels and activity. Intracellular GSH levels - poorly transported through cell walls due to its tripeptide structure - are largely established intracellularly from its constituent amino acids glutamate, glycine, and cysteine - the latter being "rate-limiting" and consequently a target for efficient supplementation by TAS-a™. Subsequently, serving as an electron donor (as part of its intracellular roles) GSH is transformed into GSSG which can readily pass through cell walls and may be lost into the extracellular media unless quickly refurbished by other antioxidant resources - the latter consequently also is a target of TAS-a™. GSH functions in several systems within the body that assist with:

  1. Detoxification of fat-soluble compounds.
  2. Supporting amino-acid transport.
  3. DNA synthesis and immune system augmentation.
  4. Quenching of free radical and other reactive oxygen species (ROS). This quenching activity is particularly important to physical and mental performance, resistance to stress and overall health.

Excessive reactive oxygen species (ROS) production as part of the normal metabolism of the body - and lower levels of GSH - have been associated with a variety of physical problems. Antioxidants have been identified as a means for intervention to enhance mental and physical performance, stress resistance and health/wellbeing.

Glutathione is the major antioxidant for reducing free radicals in the body. TAS-a™ is called a 3rd-generation targeted antioxidant system because the formula for TAS-a™ (or TAS-alpha™)was designed by taking into consideration the exact details of the way the body processes work at the cellular level. It is a precursor that stimulates the body to make glutathione.

Free radicals are created in the body under a number of different stressful conditions. A lot of oxidative stress comes from the toxins in the food we eat and the pollution in the air we breathe. Sunlight and smoking cause free radicals to form. But free radicals are also created with emotional and physical stress including the stress having infectious and degenerative diseases.

A simple way to think of oxidative stress is to think of what happens when you eat part of an apple and lay the rest down to eat later. It will turn browner and browner over time. This is oxidative stress (free radicals) at work. If you were to dip the apple in fruit juice before you laid it down it would not turn brown. That is because the fruit juice contains an antioxidant, Vitamin C, and it would neutralize the free radicals.

Since glutathione is the major antioxidant for reducing free radicals in the body, and it serves to regulate some of the other antioxidants, you can boost your immune system plus protect your body from lack of energy, sluggish thinking and premature aging by supplementing it with TAS-a™ (or TAS-alpha™).

Dietary Applications:

  1. Efficient source for the development of intracellular glutathione (GSH) antioxidant levels.
  2. Support in maintaining GSH antioxidant activity (refurbishing GSSG to GSH).
  3. Support for capillary micro-circulation.
