Vitamin D protects telomeres: a randomized, controlled trial
Telomerase activity was measured before and after 37 people were given either placebo or about 2000IU of oral vitamin D supplements per day for 16 weeks. Serum vitamin D levels for those taking the supplement increased almost 200%. The telomerase activity increased over 19% as well, while the telomerase activity of those on placebo did not change.

Vitamin C helps antidepressant drug work better
In this randomized, double-blind, placebo controlled trial, a group of patients with major depressive disorder (n=12) were given fluoxetine plus 1000mg of vitamin C daily and compared to a group (n=12) that were given fluoxetine plus placebo. After six months, those receiving vitamin C in conjunction with fluoxetine showed a significant decrease in symptoms when evaluated using three different standardized depression rating systems compared to the placebo group.

Serine improves ADHD symptoms
In this randomized, double-blind trial, 36 children diagnosed with ADHD received either 200mg of phosphatidylserine or placebo daily for two months. Those receiving phosphatidylserine showed improved memory, attention and control of impulses compared to placebo. Serine’s key role in psychiatric and neurological health has been gaining attention from studies such as this. The authors concluded that phosphatidylserine “may be a safe and natural nutritional strategy for improving mental performance.”

Are micronutrients underrated when it comes to pregnancy chances in assisted reproduction?
Several recent studies are suggesting that micronutrient status prior to and during pregnancy should get more attention. One study showed that low blood values of B vitamins and high homocysteine in mid pregnancy reduced fetal growth rates. Another study showed that low homocysteine, determined by B vitamin status, was linked to a better chance of pregnancy in women undergoing assisted reproduction. Yet another study showed that subfertile women undergoing ovulation induction who were taking a multi-micronutrient vitamin were more likely to get pregnant than women who took only a folic acid supplement. Finally, a recently published review demonstrates how increasing a woman’s ability to fight oxidative stress increases her chances of successful pregnancy via assisted reproduction.

Study sheds light on CoQ10’s role in healthy sperm
Sixty infertile men were given 200mg of CoQ10 or placebo for 3 months. CoQ10 lowered oxidative stress in semen (measured by isoprostanes and superoxide dismutase activity) and improved sperm function significantly. (Andrologia, January 2013)
