More than a third of kids are using dietary supplements. Due to the many preventable, adverse drug reactions they cause – such as arrhythmias and cardiovascular events – researchers set out to quantify pediatric and adolescent intake.
For the general population and its $6-to-8 billion supplement habit, we're learning that Vitamin D and Calcium supplements do not prevent hip fractures.
A new study in the Journal of the American Medical Association finds that there was no significant reduction of the incidence of all-type cancer in older women receiving Vitamin D and calcium supplements.
A growing number of parents choose to opt out of giving children their daily dose of milk, and switching to alternatives like almond milk or cashew milk. Perhaps they may think the alternatives offer a bit more calcium than real milk — but this is misleading: Real milk contains both calcium and vitamin D (added in the 1930s due to Rickets — a vitamin D deficiency among children), and the presence of vitamin D helps absorb the calcium.

Two new studies, which deal with the extra information a calcium scan can contribute to risk calculation for predicting coronary heart disease events over a 10-year course, found that coronary artery calcium scores of very low or zero reduced the likelihood of CHD events by about half. This can eliminate the need for statins.
Two recent studies on the health benefits associated with two commonly-used dietary supplements further add to our message here at ACSH that complementary products do very little to protect us from any types of disease, and supply further
