CLINICAL UPDATE - controversy over calcium supplements - helpful or harmful?
New meta-analysis of 15 studies that include over 12,000 people suggests that regularly taking calcium supplements might increase the risk of heart attack. However, industry contends that the meta-analysis, which only looked at calcium supplements without vitamin D, “cherry picked” results.

CLINICAL UPDATE - selenium reduces post-partum depression
Selenium supplements (100mg per day) were given to 83 women during their pregnancy while another 83 women received placebo. Symptoms of postpartum depression were significantly lower in the supplemented group .

CLINICAL UPDATE - Short telomeres predict severity of heart disease
After measuring telomeres and heart disease events in 800 men and women, researchers found that the risk of heart disease for those with the shortest telomeres equated to a chronological increase in age of about 14 years.

CLINICAL UPDATE - Specific Form of vitamin B1 reduces fatigue
Two forms of vitamin B1 were compared – dicethiamine hydrochloride (DCET) and thiamine hydrochloride (VB1HCL) for anti-fatigue properties in animal swim tests. The results indicated that the DCET form was well-absorbed into tissues and resulted in improved clinical outcomes of reduced fatigue, while the VB1HCL form did not reduce fatigue.

CLINICAL UPDATE - supplementation with omega 3 improves depression
In a double blind, controlled trial, 22 women were assessed for depression after receiving 2.5 grams of omega 3 fatty acids (1/3 DHA and 2/3 EPA) daily for 8 weeks. When compared to the same number of women taking placebo, the group taking omega 3 fatty acids had fewer clinical symptoms of depression according to the quantitative Geriatric Depression Scale. This coincided with an increase in erythrocyte omega 3 fatty acid status. In a larger study, similar results were seen after 8 weeks of supplementation on patients with more severe depressive symptoms.

CLINICAL UPDATE - The amino acid carnitine - a super nutrient?
Recent trials on the amino acid carnitine have demonstrated clinical benefits on a variety of seemingly unrelated illnesses. Its primary role in the metabolism of fatty acids may explain its diverse clinical benefits such as reduction in alcoholism cravings, increased insulin sensitivity, improved lung and heart function, and even reduction in the amount of valproate needed to treat hospitalized psychiatric patients.
