Oral Magnesium Again Reported to Help Asthma Sufferers in a Randomized Trial

However, previous Mg trials studying therapeutic effects in asthmatics have produced only mixed results. The primary factor separating the current trial from previous negative reports is duration.

Calcium for Strong Bones: Do Benefits Outweigh Risks?

by Douglas MacKay, ND  There are several limitations to this study that render the conclusions dramatically overstated. Meta-analysis can be a useful tool, but it is important to note that this meta-analysis is based on a collection of past studies that have different designs, end points, doses and study populations.Patient level and trial level meta-analysis of previously completed randomized control trials (RCTs) involving calcium supplementation. The researchers objective was to investigate the effect of calcium supplementation on the risk of cardiovascular events based on the combined data from previous RCTs. Eligible studies included RCTs using calcium supplements (elemental calcium > 500 mg/day), with more than 100 participants of mean age 40 years and study duration of more than one year. Trials involving co-administration of calcium and vitamin D were excluded from the analysis.
