Vitamin C

Vitamin C is the most widely used supplement. Humans cannot manufacture their own vitamin C; therefore it must be taken in through the diet. Vitamin C is a water-soluble antioxidant that is used all over the body. It speeds tissue growth and repair, supports hormone production, increases immune system functioning, protects the body from toxins and supports healthy cell growth. It also regulates cholesterol, blood pressure and blood clotting.

There are several types of vitamin C. Ascorbic acid is the basic form. To buffer the natural acidity of vitamin C manufacturers can bind it to other molecules. Two examples are calcium ascorbate (Ester-C) and ascorbyl palmitate. It also makes vitamin C easier for the body to absorb and decreases the loss of the vitamin through the urine. This increases the cost of the supplement but it is beneficial to those taking high doses of vitamin C and those who cannot tolerate acidic substances.

Vitamin C comes in a variety of dosage forms including conventional pills, time-released tablets, syrups, powders and chewable tablets. A qualified practitioner can even administer it intravenously. Vitamin C is usually derived from corn or dextrose but tapioca-sourced C is also available. Vitamin C is often combined with bioflavinoids like hesperidin and rutin. These substances work synergistically with Vitamin C. Rose hips are a good substitute for straight vitamin C because they are the richest natural source of vitamin C. Rose hips are also a good source of bioflavinoids. Vitamin C is lost in the urine only a few hours after it is taken so frequent dosing is important.

Vitamin C needs are increased if you use oral contraceptives, antidepressants, analgesics, anticoagulants, steroids or alcohol. Cooking, light, oxygen, tobacco smoke and carbon monoxide destroy Vitaminn C. Vitamin C supplements should be taken away from ginseng. Some diabetic medications and sulfa drugs may be less effective when taken with vitamin C. Cancer patients undergoing treatment should seek advice regarding vitamin C supplementation.

Vitamin' B-6

Pyridoxine is a water-soluble B vitamin. There are several forms of B6 including pyridoxine, pyridoxal and pyridoxamine. B6 is involved in more body functions than any other single nutrient. It maintains fluid balance in the body, which can be useful for women who experience PMS bloating or individuals with carpal tunnel syndrome. B6 helps to make hemoglobin, the oxygen- carrying component of red blood cells. It is needed to synthesize genetic material and is essential for normal cellular growth.

B6 is required for the production of neurochemicals in the brain, such as serotonin, which regulates pleasurable experiences and appetite, and GABA, which calms the body. Therefore, B6 is useful for a variety of neurological disorders including autism and hormonally related depression. It plays an important role in the conversion of homocysteine into harmless substances. Homocysteine damages the inner lining of arteries and high levels of homocysteine are correlated to an increased risk of atherosclerosis. B6 can be used to treat anemia, allergies, arthritis, asthma, kidney stones, pregnancy-related nausea and MS.

All of the B vitamins work together and are best used by the body in a B complex, which is why many B complex supplements include a small dose of B6 in them. If additional supplementation of B6 is needed it should be taken in addition to a good B complex. Most B vitamins are water-soluble and any extra from large doses is flushed out of the body easily, therefore it's best to take lower dosages of the B complex several times a day than one larger dose. Spray or sublingual forms of B vitamins are easily absorbed, as are capsules - if your digestion is healthy, then the tablet form is usually suitable for most people.
