Vitamin and Mineral Supplements
Vitamin and Mineral Supplements are now recommended even by the mainstream
medical profession to help prevent vitamin and mineral deficiencies when the
diet is not adequate to provide all necessary nutrients. Of course, it is just
about impossible to achieve an "adequate diet" with the groceries
you can buy these days. Larger amounts of some nutrients protect against future
disease. The typical SAD (Standard American Diet) supplies inadequate amounts
of several essential vitamins and minerals. Recent nutrition surveys in the
U.S. have found large numbers of people consume too little calcium, magnesium,
iron, zinc, copper and manganese.
Some specialized diets, including weight-loss, vegetarian, or macrobioticcan
create their own deficiencies. Studies have found that elderly people living
in their own homes, often have dietary deficiencies of vitamin A and vitamin
E, calcium, and zinc, and occasionally of vitamin D, vitamin B1, and vitamin
B2. Premenopausal women often consume insufficient amounts of calcium, iron,
vitamin A, and vitamin C.
Vitamin A: Vitamin A is important for the function of the immune system.
Beta-carotene is a precursor to vitamin A, with a separate role in human health.
Studies of smokers have reported that supplements of synthetic beta-carotene
increased the risk of both heart disease and lung cancer. Duh! Take the real
thing.
Vitamin B: B-vitamins, including thiamine (vitamin B1), riboflavin (vitamin
B2), and niacin (vitamin B3), are added to white flour products and other foods
that have been depleted of those vitamins. Unfortunately, your regulators can't
anticipate all your needs, so you'd be better off eating natural foods, because
industrial food producers will not put into their product anything beyond the
regulated amount. Biotin, is usually not a problem. Pantothenic acid (vitamin
B5), on the other hand, appears to be in short supply in the typical diet. Vitamin
B6 (pyridoxine) is important in prevention of heart disease by helping to regulate
blood homocysteine levels. Folic acid deficiency is common in the U.S.,
affecting about 11% of healthy people. While FDA raised the required supplementation
levels, these increases are not enough to prevent heart disease and birth defects.
The requirement for folic acid doubles during pregnancy. Vitamin B12
deficiency occurs in people taking acid-blocking drugs. Folic acid, B12 and
pyridoxine (vitamin B6) are important for the control of homocysteine levels
in the blood. Elevated homocysteine levels are associated with several diseases,
including heart disease, stroke, Alzheimers disease, and osteoporosis.
Daily supplementation with B-vitamins lowers elevated homocysteine levels.
Vitamin C: Deficiency was found in college students and smokers. The
recommended doses are much too low to counteract stressful lifestyles or to
cure a serious disease.
Vitamin D: Obtained from the diet or from sunlight exposure, but in
insufficient quantities by most. Vitamin D insufficiency is associated with
bone loss and fractures.
Vitamin E: 27% of the U.S. population had low blood levels of vitamin
E according to a recent study. Supplementing with 100 IU per day lowered risk
of heart disease, and 400800 IU of vitamin E per day reduced the risk
of nonfatal heart attacks.
Vitamin K deficiency severe enough to cause bleeding problems is rare,
but osteoporosis is common.
Calcium: Good calcium nutrition throughout life is essential for achieving
peak bone mass and preventing deficiency-related bone loss. The protective effect
of calcium on bone is one of very few health claims permitted by the FDA. Aim
for 1,500 mg daily calcium intake.
Phosphorus is a necessary nutrient, but diets are almost always adequate.
Magnesium: Deficiency is very common, and its symptoms are wide ranging.
Effective magnesium supplementation must be transdermal (through your skin).
Potassium: Serious deficiencies are rare, but subclinical problems are
rampant. Raising potassium intake can prevent high blood pressure and stroke.
The maximum amount of supplemental potassium allowed in one pill (99 mg) is
far below the recommended amounts (at least 2,400 mg per day). The best way
to get extra potassium is to eat several servings per day of fruits, vegetables,
or their juices, or Superfoods.
Iron deficiency is common with vegetarians, menstruating girls and women,
pregnant women, and female and adolescent athletes. Excessive iron intake has
been associated in with heart disease, some cancers, diabetes, increased risk
of infection, and exacerbation of rheumatoid arthritis.
Iodine: Iodized salt is supposed to take care of iodine intake, but
there are many other problems associated with refined salt. Consider kelp, dulse,
or superfoods.
Zinc help increase immune function, but too much zinc impairs it. 50
mg of zinc per day is plenty. Regular supplementation with zinc should be complemented
by copper supplements to prevent zinc-induced copper deficiency.
Copper: Supplementation with 3 mg per day of copper may help prevent
bone loss. Copper should be taken with zinc supplements to balance its effect.
Manganese: Low in refined and processed foods, manganese has been associated
with osteoporosis and bone loss in postmenopausal women. Manganese should be
included with iron supplements, since iron can reduce manganese absorption and
cause lower body levels of manganese.
Chromium: deficiency has been associated with blood sugar and cholesterol
abnormalities.
Selenium: RDA of 70 mcg per day of selenium appears to be much too low:
recent double-blind study found that people given a supplement of 200 mcg of
yeast-based selenium per day for 4.5 years, had a 50% drop in the cancer death
rate over seven years compared with the placebo group.
Molybdenum is an essential trace element with low potential for toxicity.
Deficiencies lead to serious amino acids absorption problems.
