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.

Zinc Deficiency Affects DNA Damage, Oxidative Stress, Antioxidant
Defenses, and DNA Repair in Rats.
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.

to ABSTRACT:
A high menaquinone intake reduces the incidence of coronary heart
disease.
CLINICAL
UPDATE - CoQ10 helps 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.
(Biochemical Pharmacology, July 2009)
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.
