If you’ve read the ads in health magazines, you may have seen claims that large doses of B6 can alleviate depression, premenstrual syndrome (PMS), asthma, muscle fatigue, and even autism. But you shouldn’t take these claims too seriously: scientific evidence does not support most of them. Proponents of B6, for example, claim that doses of 50 to 200 mg can “cure” PMS. According to research studies, a placebo seems to be just as effective. Read the rest of this entry »

Many statements have been made about vitamin B12, most commonly that B12 can boost energy. Scientific evidence does not substantiate most of these claims, although research does show promise in the area of cardiovascular health.
How Much Vitamin B12 Do You Need?
Your body needs little vitamin B12. Consequently, RDAs are low— for example, only 2.0 mcg for adult men and women. Read the rest of this entry »

Keeping up with all of the recent research into the potential health benefits of vitamin E is difficult. The impressive findings of the best of this research, however, are impossible to ignore.
A growing body of research indicates that vitamin E can provide protection against a variety of cancers, including oral, lung, cervical, and breast cancers. For example, an eight-year Finnish study of 36,265 adults concluded that individuals with low blood levels of alpha-tocopherol (vitamin E) were 1.5 times more likely to develop cancer than people with higher amounts.

Before you decide that you need to take vitamin supplements or change the way you eat, you should know where you stand and how much improvement you really need. In fact, most people get all of the vitamin K they need through diet alone.
To help you analyze your current diet, we’ve developed a system you can use to calculate your approximate vitamin K intake. Following is a list of vitamin K food sources, arranged according to the percentage of our Optimal Daily Allowance of vitamin K contained in them. Since 1 cup of raw carrots contains 17.81 mcg of vitamin K and the ODA for vitamin K is 80 mcg, we’ve listed carrots in the 20 Percent category. (We have erred on the conservative side when rounding off percentages.) Read the rest of this entry »

How Much Calcium Do You Need?
Not everyone agrees with the formal RDAs for calcium. A National Institutes of Health consensus panel on osteoporosis has advised that women consume more calcium than recommended in the RDAs-1,500 mg in the years after menopause if they are not taking supplemental estrogen. The National Osteoporosis Foundation recommends 1,000 mg per day for postmenopausal women who are not on estrogen replacement therapy.
Although the RDAs call for only 800 mg of calcium for men and women over the age of 25 (with an increase to 1,200 mg for pregnant and lactating women), we recommend a daily intake of 1,500 mg for everyone. Women clearly need more calcium to help protect them against osteoporosis, even if they are postmenopausal and on hormonal replacement therapy (which can also help protect their bones).

Hypertension Cure
Magnesium may help reduce high blood pressure. Some evidence suggests that too little magnesium in the body causes muscles in the blood vessel walls—the so-called vascular smooth muscles— to constrict. As the channels in these vessels become narrower, blood pressure tends to increase.
In ongoing studies, researchers are examining magnesium as a potential treatment for other health disorders, from osteoporosis to asthma to diabetes. To date, this research has been too limited to produce any conclusions. Read the rest of this entry »
