Vitamin B12

New studies show that supplemental vitamin B12 absorbs better through the stomach than was previously thought. These reports, published in mainstream medical journals, show that orally administered vitamin B12 supplements are effectively absorbed by more than 99 percent of humans (B12 is difficult to absorb from the digestive tract only when it is tightly bound to food). Vitamin B12 plays a role in many enzymatic processes required to maintain good health, and works synergistically with folic acid and TMG to enhance DNA methylation and reduce toxic homocysteine in the blood. Also, elderly people can suffer from severe neurological impairment if they are deficient in vitamin B12.

The 1998 Life Extension Mix formula contains five times more vitamin B12 than in the past. In addition to cyanocobalamin, another form of vitamin B12 called hydroxyl cobalamin has been added that works via different enzymatic pathways.

Biotin

Biotin is a B-complex vitamin that provides health benefits ranging from the control of blood sugar levels to the improved appearance of hair and nails. Biotin has been shown to ameliorate abnormal glucose metabolism in diabetics by enhancing the activity of the biotin-dependent enzyme required for the promotion of proper glucose utilization.

The potency of biotin in the 1998 Life Extension Mix formula has been tripled.

Pyridoxal-5-Phosphate

Vitamin B6 readily converts to its enzymatically active form (pyridoxal-5-phosphate) in most people. Some people do not convert vitamin B6 as well as others, so the 1998 formula includes enough biologically available pyridoxal-5-phosphate to ensure that no one taking Life Extension Mix will suffer from a "sub-clinical" (that is, early and not easily detected) vitamin B6 deficiency. The total amount of vitamin B6 in the formula has been reduced to guard against B6-induced peripheral neuropathy. While the amount of B6 in previous versions of Life Extension Mix would not cause toxicity, some people take additional vitamin B6 in other nutrient formulas, and we want to make sure that no one inadvertently takes too much B6 over an extended period of time.

PABA

It is well known that PABA absorbs dangerous ultraviolet B (UVB) radiation. However, PABA also protects against ultraviolet A (UVA) damage via a unique free radical-scavenging ability. Thus, PABA is useful in protecting against photocarcinogenesis by wide-range UV radiation. PABA also inhibits the formation of thrombin-induced thromboxane (a potent inducer of platelet aggregation and a constrictor of arterial smooth muscle) in human platelets, and thus reduces the risk of abnormal blood clot formation, blocking the flow of blood (thrombosis).

Four times more PABA has been added to the 1998 Life Extension Mix formula.

Ginger Extract

The leading cause of disability and death in the Western world is thrombosis. Most heart attacks and strokes are caused by thrombotic events. Many of the nutrients in Life Extension Mix have proven anti-thrombotic properties. Ginger, consumed worldwide as a spice and flavoring agent, possesses antioxidative and anti-inflammatory properties as an extract, and may also be one of the most effective nutrients in preventing thrombosis. In one study, a single dose of 10 grams of powdered ginger produced a significant reduction in platelet aggregation.

Other findings suggest that ginger could be an effective anti-emetic (preventing nausea and vomiting) for patients on cancer chemotherapy. Further, there is evidence that ginger protects against skin tumor promotion. In a mouse study, the topical application of ginger extract protected against the genesis and spread of skin tumors.

We've added a pharmaceutical ginger extract to the new Life Extension Mix to provide additional protection against thrombosis, inflammation and other pathological conditions.

Lysine

Dr. Linus Pauling's last great work was to show that specific components in the blood called apolipoproteins are involved in atherosclerosis and valvular stenosis. Dr. Pauling showed that vitamin C and lysine can protect against apolipoprotein-induced vascular disease. The 1998 Life Extension Mix formula contains the amount of lysine (500 mg) found in most lysine supplements. Those with valvular stenosis (narrowing) or severe atherosclerosis should take additional lysine under the care of a physician.

Magnesium

Magnesium deficiency is a prime culprit in the epidemic of arterial disease that plagues the Western world. Foundation members have obtained high doses of magnesium ever since Life Extension Mix was introduced. Different forms of magnesium have shown other beneficial effects at the cellular level in addition to vascular protection. The new Life Extension Mix contains an advanced magnesium complex consisting of magnesium arginate, magnesium taurinate and magnesium glycinate to provide magnesium to different parts of the cell.

Natural Vitamin E

The 1998 Life Extension Mix contains 400 IU of d-alpha tocopheryl succinate, a natural form of vitamin E that appears to protect against cancer better than other forms of vitamin E. The previous formula only provided 250 IU of d-alpha tocopheryl succinate. The total amount of natural and synthetic vitamin E in the new formula is now 500 IU per daily dose.

In order to make room for all these nutrients, calcium has been removed from the formula, except for the small amount found naturally in compounds such as calcium ascorbate and calcium pyruvate. Life Extension Mix has never been a high source of calcium, which is required in high doses by women over 40. Women seeking to maintain bone density should take Mineral Formula For Women. Men can obtain supplemental calcium and additional magnesium in Mineral Formula For Men.

Also reduced in the new formula is the amount of vitamin B1, because the higher amount of NAC provides similar antioxidant protection. And the amount of vitamin B6 has been reduced because, in addition to protecting against accidental overdosing, the consensus of scientific opinion is that 100 mg a day of B6 is adequate for most people. However, as noted above, the active form of vitamin B6 (pyridoxal-5-phosphate) has been added to ensure that anyone using Life Extension Mix will obtain adequate amounts of this important vitamin.

While the added ingredients in the new Life Extension Mix have caused its price to increase, Foundation members will still be paying the lowest "cost per milligram" price for the pharmaceutical-grade nutrients found in every bottle of this unique formula.
