The vitamin B-complex refers to all of the known essential water-soluble vitamins except
for vitamin C. These include thiamine (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3), pantothenic acid (vitamin
B5), pyridoxine (vitamin B6), biotin, folic acid and the cobalamins (vitamin B12).
"Vitamin B" was once
thought to be a single nutrient that existed in extracts of rice, liver, or yeast. Researchers later discovered these extracts
contained several vitamins, which were given distinguishing numbers. Unfortunately, this has led to an erroneous belief among
non-scientists that these vitamins have a special relationship to each other. Further adding to confusion has been the "unofficial"
designation of other substances as members of the B-complex, such as choline, inositol, and para-aminobenzoic acid (PABA),
even though they are not essential vitamins.
Each member of the B-complex has a unique structure and performs unique
functions in the human body. Vitamins B1, B2, B3, and biotin participate in different aspects of energy production, vitamin
B6 is essential for amino acid metabolism, and vitamin B12 and folic acid facilitate steps required for cell division. Each
of these vitamins has many additional functions. However, contrary to popular belief, no functions require all B-complex vitamins
simultaneously.
Human requirements for members of the B-complex vary considerably-from 3 mcg per day for vitamin
B12 to 18 mg per day for vitamin B3 in adult males, for example. Therefore, taking equal amounts of each one-as provided in
many B-complex supplements-makes little sense. Furthermore, there is little evidence supporting the use of megadoses of B-complex
vitamins to combat everyday stress, boost energy, or control food cravings, unless a person has a deficiency of one or more
of them.
Heart-healthy
folic acid, B6, and B12 may play a role in the maintenance of normal homocysteine levels. In addition, regular cardiovascular
exercise and optimal levels of nutrients contribute to a healthy heart.
There are a number of other nutritional
ingredients that have shown to support heart health.
Garlic- Provides dietary support for normal
healthy cardiovascular function.
CoEnzyme Q10- An antioxidant that helps to support cardiovascular
health. It exists in all cells of the body and, when combined with L-carnitine, CoQ10 supports healthy hearth and blood vessel
function.
Soy Protein- A plant source of protein. The FDA has determined that 25 grams per day,
as part of a diet low in saturated fat and cholesterol, may help lower cholesterol and reduce the risk of heart disease.
Vitamin E- Helps to support a healthy cardiovascular system. The natural form (d-alpha) is the body's
preferred form of vitamin E.
Omega-3 Fatty Acids- EPA and DHA are naturally found in fish oils
and are vital for healthy heart function.
Here are some tips for your
cardiovascular health
- Avoid foods rich in saturated fats.
- Enjoy a high-fiber diet.
- Consume a diet adequate in Vitamins E, B6, B12, folic acid and the mineral selenium.
- Exercise regularly.
