Is carnitine the answer for male infertility?
A group of men (n=96) who had been diagnosed as infertile for at least 18 months were given the following nutritional formulation daily for four months: L-carnitine, acetyl-L-carnitine, fructose, citric acid, selenium, coenzyme Q10, zinc, vitamin C, vitamin B12 and folic acid (see abstract for exact dosages). At the end of the study, sperm motility improved and 16 of the patients had achieved pregnancy. The authors concluded that carnitine may be the key component of the supplement cocktail for improving sperm quality. (Italian Archives of Urology and Andrology, September 2012)

Vitamin D helps leg ulcers heal
In this double-blind, placebo controlled trial, 26 patients with leg ulcers were given either placebo or 50,000 IU vitamin D weekly for two months. Leg ulcer size, blood levels of vitamin D and pain was measured before and after the two month trial. In the vitamin D group, leg ulcers were reduced in size by 28% while the placebo group had only a 9% reduction in ulcer size. The authors stated “there was a trend toward better healing in those with vitamin D reposition.” (Journal of Brazilian College of Surgeons, October 2012)

This review emphasizes how methyl donor nutrients such as choline, folic acid and methionine interact and how consumption (via supplement or food) of one can have sparing effect s on another – such as choline’s sparing effect on methionine, for example.
