CLINICAL UPDATE - Zinc deficiency causes dna damage
A cell's ability to repair damaged DNA and resist oxidative stress is decreased by zinc deficiency, according to a recent animal study. Once cells were repleted with zinc, however, antioxidant defenses improved and normalized.

CLINICAL UPDATE - high vitamin k intake reduces heart disease
Vitamin K intake of more than 16,000 women aged 49-70 years was assessed. Researchers found that vitamin K2, which is the form synthesized in the intestine by beneficial bacteria, but not vitamin K1, the form found in plants, showed a significant and inverse association with heart disease.

CLINICAL UPDATE - Coq10 heps liver function
The antioxidant effects of coenzyme Q10 on lipid peroxidation are well known, but researchers found that the supplement also reduces obesity-related inflammation and oxidative stress in the liver.

Link to ABSTRACT: Coenzyme Q10 supplementation lowers hepatic oxidative stress and inflammation associated with diet-induced obesity in mice.
CLINICAL UPDATE - High dose, short term folate may cut blood pressure
Thirty healthy post-menopausal women received either 15mg folate daily or placebo for three weeks. Blood pressure and homocysteine were both reduced in the folate but not placebo group.

CLINICAL UPDATE - Lp(a) linked to arthritis, blindness and heart disease
New studies link the dangerous lipoprotein(a) to rheumatoid arthritis and diabetic retinopathy, while a large-scale meta-analysis of over 126,000 participants confirm the association of Lp(a) with coronary heart disease. Research also found that carnitine enhanced the beneficial effects of a statin on Lp(a) levels while fenofibrates increase it.
