Acetyl-L-carnitine reverses peripheral nerve damage in clinical trial

Acetyl-L-carnitine (ALC) is a substance involved in the transport of fats to the cellular locations where they can be metabolized and their energy made available. A recent clinical trial tested the effects of ALC supplementation (1500 mg twice daily) on peripheral nerves that had been damaged by HIV-suppressing drugs. After 6 months of ALC treatment the amount of nerve regeneration was dramatic: compared with controls, epidermal, dermal and sweat gland innervation reached 92%, 80% and 69%, respectively.

Vitamin D, multiple sclerosis, osteoporosis, sun exposure

Vitamin D has been much in the news lately, thanks to a battle between dermatologists over whether sun exposure is an unmitigated evil or is beneficial in small amounts. The dermatology industry’s position is that all sun exposure is harmful, since it damages DNA and causes skin cancer, and should therefore be avoided completely.

Theanine supplementation suppresses fat accumulation in obesity study

Green tea has been used in dieting supplements for several years because of its supposed ability to speed up fat metabolism. A recent study in mice has now confirmed this concept and identified the main substances responsible for it: theanine and catechins. Researchers at Shizuoka University showed that a diet containing 0.03% theanine, either by itself or in combination with catechins or caffeine, resulted in significantly less weight gain than control diets. Blood triglyceride levels were also significantly reduced.

Rhodiola recommended for libido enhancement

Rhodiola rosea is a perennial herbaceous plant native to northern Asia and Europe, used for centuries as a stimulant, to eliminate fatigue, and to prevent high-altitude sickness. Its roots and stems contain several unusual substances thought to be responsible for these effects. More recently, Rhodiola extracts have been studied and promoted as cognitive enhancers and stress reducers.

Lutein reverses symptoms of Macular Degeneration in rigorous clinical trial

Evidence has been accumulating for several years that supplementation with lutein can prevent or reverse symptoms of macular degeneration. Now a rigorous clinical trial conducted at a Veterans’ Administration eye clinic in Chicago confirms the effectiveness of this treatment. Ninety patients with Macular Degeneration received either lutein supplements at 10 mg/day or a placebo. Patients receiving lutein showed a significant improvement in retinal pigment density, acuity, and contrast sensitivity.

Folic acid and other supplements may help prevent osteoporosis

Two recent studies have confirmed suspicions that people with elevated blood homocysteine levels have a higher incidence of osteoporosis and hip fractures. The implication is that methods for lowering homocysteine levels should also lower the incidence of osteoporosis and hip fractures. Among the nutritional supplements having homocysteine-lowering effects are folic acid, melatonin, trimethylglycine, vitamin B-6, and methylcobalamin.

Coenzyme Q10 reduces frequency of migraine attacks

A Swiss study of 42 migraine sufferers has shown that Coenzyme Q10 supplementation at 100 mg three times per day reduces the frequency and symptoms of migraine attacks. About half of the patients on Q10 saw the number of migraine attacks they suffered per month reduced to about half.

Tea polyphenols score against prostate cancer, leukemia

Both green and black tea are of great interest to cancer researchers because of their anti-cancer effects. A variety of different cancers have been shown to be sensitive to ‘polyphenol’ compounds found in tea, and epidemiological studies have shown heavy tea-drinking to be correlated with lower cancer incidence.

Why does lycopene kill cancerous prostate cells?

An epidemiological study in 1995 showed that prostate cancer risk is lower in men who consume more lycopene. Lycopene immediately became the focus of many researchers seeking to understand the molecular mechanisms responsible for this action against prostate cancer. The most common speculation has been that lycopene’s antioxidant behavior is somehow responsible. Another explanation, based on lab experiments, is that lycopene may interfere with molecular signalling pathways that cancer cells use to respond to growth factors.
