Calcium is essential to the healthy functioning of the blood, heart, brain, and bones. It is very important for children to get plenty of calcium in order to grow properly. People over 40 may benefit from calcium by avoiding age related weakening of the bones.
Research suggests that we need 1,000-1,300 mg of calcium per day. Liquid calcium is a highly bioavailable form of the supplement which may be easier for kids and the elderly to swallow. As a liquid supplement, calcium citrate or calcium carbonate is 95-96% absorbable, so it helps take the guess work out of measuring the amount of the supplement that actually makes it into the body. And because it is better to take many doses throughout the day, liquid calcium is more convenient than large pills.
The absorption of calcium in the body requires magnesium and vitamin D to be present in the body so finding a good supplement that contains both calcium and magnesium is a good idea. You may decide to buy one that contains vitamin D as well.
If you are not able to eat when taking calcium, liquid calcium citrate does not need to be taken with food.
A word of caution: When purchasing liquid calcium with magnesium supplements look for brands that have the USP (United States Pharmacopeia) symbol or have the word “purified” on the label. Brands that are not purified may contain lead or other toxic metals.
