N-Acetyl-L-Cysteine
600 mg, 60 vegetarian capsules Item Catalog Number: 01534

L-cysteine is a conditionally essential amino acid, one of only three sulfur-containing amino acids, the others being taurine (which can be produced from L-cysteine) and L-methionine (from which L-cysteine can be produced in the body by a multi-step process). Cysteine plays a role in the sulfation cycle, acting as a sulfur donor in phase II detoxification and as a methyl donor in the conversion of homocysteine to methionine.136-138 Cysteine also helps synthesize glutathione, the body’s most important intracellular antioxidant and a vital detoxifier.139-142

N-acetyl-L-cysteine (NAC) is the acetylated form of L-cysteine that has been used to break up pulmonary and bronchial mucous.143-146 It is very efficiently absorbed and has been shown to protect cells directly and support the immune system.146-155 NAC is an antioxidant and a free radical-scavenging agent that increases intracellular glutathione at the cellular level. NAC can act as a precursor for glutathione synthesis as well as a stimulator of the cytosolic enzymes involved in glutathione regeneration.146 NAC has been shown to protect against oxidative stress-induced neuronal death in cultured granule neurons.156

Buffered Vitamin C Powder 454 gram

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.1-8 Vitamin C also promotes the absorption of iron, while preventing its oxidation.9,10 Vitamin C is a vital cofactor to the formation of collagen, the connective tissue that supports arterial walls, skin, bones, and teeth.4-6 A major immune-supporting activity of vitamin C is boosting glutathione levels in human lymphocytes,38 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.11-14 Physical stresses on the body such as ingestion of heavy metals,15-20 cigarette smoking,21-24 immune impairment,25-31 extreme temperatures,31-36 and chronic use of certain medications such as aspirin also signal the need for increased intake of vitamin C.37

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.

Food Supplement 454 g
Serving Size: 1 rounded teaspoon (approximately 5 g)
Amount per Serving
Vitamin C (as ascorbic acid) 4000 mg
Calcium (as calcium carbonate) 145 mg
Magnesium (as magnesium carbonate) 55 mg
Zinc (as zinc gluconate) 2 mg
Potassium (as potassium carbonate) 365 mg

RI = EU Reference Intake, * no RI available.

Ingredients: Ascorbic acid, calcium carbonate, magnesium carbonate, zinc gluconate, potassium carbonate.

Dosage and use
Mix one (1) teaspoon of Buffered Vitamin C Powder into a glass of water. Wait for the fizz to stop before consuming. The minerals buffer out normally acidic vitamin C to make a pleasant tasting drink. To ensure product consistency store tightly closed in a cool, dry place.

Caution
This product may cause diarrhoea, if taken in high doses, especially on an empty stomach. For optimal benefits, begin with low doses during meals and gradually increase it.

Cran-Max® Cranberry Whole Fruit Concentrate

Cran - Max contains concentrated cranberry made from the complete cranberry using a unique process, with no added sugar. Each capsule of this product contains powerful polyphenols, organic acids and antioxidants that provide the same benefits as drinking cranberry juice cocktail minus calories. An advantage of Life Extension’s Cran-Max® is that it only requires once a day dosing.

The anatomy of the female urinary tract differs greatly from men, resulting in the need for additional nutritional support for women. A wealth of published studies indicates that cranberry polyphenols may help to support a healthy urinary tract.63-67

Cranberries have been known for decades to promote a healthy urinary tract. Clinical research demonstrates that cranberries’ proanthocyanidins are powerful antioxidants that can reduce oxidative stress.72 A double-blind comparison study confirms that Cran-Max® helps support a healthy urinary tract.73 Each Life Extension Cran-Max® capsule contains 500 mg of cranberry concentrate to promote urinary tract health.66,74-84 Each Cran-Max® capsule also contains:

The synergistic, complete spectrum activity of the entire cranberry whole fruit
A unique delivery system that protects its cranberry constituents from degradation

Antioxidants
Cran-Max® contains concentrated cranberry made from the complete cranberry using a unique, patent-pending process. No sugar is added. Each capsule of Cran-Max® contains powerful polyphenols, organic acids, and antioxidants, providing the same benefits as drinking cranberry juice cocktail, but without the calories. An advantage of Life Extension’s Cran-Max® is that it only requires once a day dosing!

Beta-Carotene
25,000 IU 100 softgels Item Catalog Number: 00664
Vitamin A (retinol) is a yellow, fat-soluble, generic term for a large number of related compounds obtained from some carotenoids by conversion in the liver, its storage organ. Retinol (an alcohol) and retinal (an aldehyde) are often referred to as preformed vitamin A. While carotenoids are widely distributed in such foods as green and yellow vegetables, retinol is not found in any vegetable sources, but is concentrated in egg yolks and the livers of many animals. Vitamin A, either from animal sources or synthesized in our own liver, is essential for growth and reproduction, maintaining healthy vision, and supporting protein synthesis and cell differentiation.

Vitamin A and its analogs have shown the ability to help maintain proper DNA function.1-3 One study, however, has shown that for certain lifestyles (e.g., smokers) supplemental intake of too much beta-carotene in the absence of other carotenoids and antioxidants (such as at least 400 IU/day of vitamin E) may be harmful.4

Beta-carotene is the most potent precursor to vitamin A, but its conversion to vitamin A in the body is limited by a feedback system. It is an important antioxidant in its own right and one that can only build up to toxic levels in rare circumstances. Beta-carotene helps support immune health by enhancing the function of the thymus gland.5,6
