- A research team from Tufts University reviewed benefits and harmful effects of calcium supplements on cardiovascular diseases.
- New evidence based guidelines for Calcium and Vitamin D supplementation was laid by the National Osteoporosis Foundation and American Society for Preventive Cardiology.
- The guidelines stated that supplementing calcium either with or without Vitamin D was considered to have a safe cardiovascular outcome.
Clinical Guidelines for Calcium and Vitamin D supplementation from the National Osteoporosis Foundation and American Society for Preventive Cardiology was published in Annals of Internal Medicine.
A research team from the Tufts University School of Medicine, reviewed trials and carried out various studies to find out the benefits and harmful effects of calcium supplements on cardiovascular outcomes.
The new guidelines state that supplementation of calcium with or without Vitamin D can be considered safe for the heart. Vitamin D can be taken either through diet or supplements and the safe limit must not exceed more than 2000 -2500mg/d.
The findings of the research study from Tufts University will help in framing the clinical guideline from National Osteoporosis Foundation and American Society for Preventive Cardiology.
Around 31 studies were included in the review. Out of the four trials which were reviewed, there were no significant difference for heart diseases or mortality between groups who received calcium supplements alone or along with vitamin D when compared to placebo. It is impossible to achieve excessive calcium intake through diet, safety or supplementation since none of the 27 cohort studies were totally linked to diet, supplemental calcium intake to cardiovascular and cerebrovascular diseases.
Based on the specific review trials, Calcium intake from food or supplements at recommended levels will be considered safe for healthy adults.
