Your Good Health Demands The Guaranteed Advantage and Benefits Coenzyme and Stabilized B-Vitamins

Research has shown that homocysteine, a toxic amino acid, is associated with depression. About one-third of all depressed patients have low levels of Vitamin B-12 or folic acid.

Vitamin deficiencies are also associated with dementia. For example, about 16% of dementia patients have Vitamin B-12 deficiency. Not surprisingly, a Harvard study linked Alzheimer's disease to elevated homocysteine blood levels (hyperhomocysteinemia).

Dementia and heart disease are also more common in depressed people.

Stroke is a condition that occurs more often in people with elevated homocysteine blood levels. Supplementation with folate and methylcobalamin (coenzyme Vitamin B-12) has improved hyperhomocysteinemia.

Stroke is also associated with between a two- and fourfold increase in risk of subsequent hip fractures. In a controlled study by Sato et al., the risk of fractures were also reduced by 80% using methylcobalamin and folate supplementation.

Studies show folic acid supplementation reduces the risk of spina bifida and other neural tube defects. As a result, it has been used to fortify foods.

Folic acid supplementation, however, can mask Vitamin B-12 deficiency, thereby causing this common vitamin deficiency to go undetected.

Everyone should take supplemental Vitamin B-12 to avoid the damage to the brain, heart, bones, and immune system associated with Vitamin B-12 deficiency.

World-wide, one in five pregnant women has folic acid deficiency. In Guatemala, one in three children has deficient or marginal Vitamin B-12 levels. Most of these children also have problems with chronic infections and bacterial overgrowth, interfering with Vitamin B-12 absorption. Imagine if all children developed their full potential by receiving all essential nutrients.

Vegetarians, and people who eat very little meat, run the risk of developing Vitamin B-12 deficiency. Many vegetarians also have elevated homocysteine levels. Vitamin supplementation is essential for anyone in this category.

The body rids itself of homocysteine build-up with the aid of essential nutrients.

Coenzyme Vitamin B-12 (methylcobalamin) and folate (5-methyltetrahydrofolate) work together to change the toxic amino acid, homocysteine, into the beneficial amino acid, methionine.

Coenzyme Vitamin B-6 (pyridoxal-5-phosphate) helps convert it into cysteine.

Coenzymes are small organic molecules that are required by enzymes to power chemical reactions in the body.

Most coenzymes are derived from the vitamins found in food or supplements containing synthetic forms of vitamins. The production of coenzymes require the transformation of food-derived and synthetic vitamins by specific enzyme systems.

Non-coenzyme supplementation does not have the same robust effect on homocysteine nor does it reduce the risk of recurrent stroke. B-complex vitamin supplements have the largest impact on homocysteine levels, even though emphasis has been placed on the impact of single B-vitamins such as folate.

Methylcobalamin is the most common form of Vitamin B-12 found in the blood. Another coenzyme form of Vitamin B-12 (adenosylcobalamin) is found in the mitochondria (the cell's energy factories). It helps eliminate methylmalonic acid within the mitochondria.

Coenzyme and stabilized vitamins are more easily absorbed.

Calcium folinate, folinic acid and 5-methyl-tetrahydrofolate (as in the formulation found in Premium Brain Support™) are examples of stabilized folates. Dietary folates and folic acid found in most supplements will degrade more readily when exposed to light, air and stomach acid.

Supplement optimization, through the incorporation of coenzymes and stabilized vitamins, is an enormous advantage for people who have digestive problems.

Digestive problems are commonplace and can prevent your body from absorbing vitamins from food.

If you drink any alcohol, take certain medications, or have an infection, you may not be able to absorb or metabolize synthetic vitamins or the building blocks of vitamins found in food.

Many women take too much Vitamin B-6 in its non-coenzyme form, pyridoxine. The average daily intake is 120 mg., and above 200 mg. a day, people run a high risk of developing liver and peripheral nerve damage. These problems can slowly develop even at 120 mg a day, especially in smaller women, who are getting more Vitamin B-6 per pound than larger women.

Liver health also varies among people. Hepatitis and other liver diseases, or taking certain medications may cause problems metabolizing Vitamin B-6. Women taking oral contraceptives need supplemental Vitamin B-6.

The coenzyme form of Vitamin B-6 (pyridoxol-5-phosphate) is safer and easier to absorb than pyridoxine.*
