Best Calcium Citrate Supplements

Best Calcium Supplements

In this post, we’ll be tuning in on some of the best calcium citrate supplements. The reason we will be focusing on calcium citrate instead of calcium carbonate is because of its high bioavailability and its easily absorbable nature.

Calcium citrate isn’t only twice as bioavailable as calcium carbonate, but is also easily absorbed even when taken on an empty stomach. The fact calcium citrate can be taken at any time of day also makes it a more viable option for people like the elderly. Used for the prevention and treatment of calcium deficiency, calcium citrate is often taken with vitamin D.

The results are a number of health benefits, including – the prevention of bone disorders, reduced blood pressure, excess phosphate removal, reduced cancer risk, and improved absorption. Calcium itself has many uses to the body such as in the formation of blood clotting, contraction and relaxation of blood vessels, formation of bones, and neuronal message transmission.

This is why taking a calcium citrate supplement can be so important to general health. This is also true since we don’t always get the calcium we need through out diet. Studies have shown that more than a third of individuals don’t get enough calcium, an essential mineral for the building and maintenance of stronger bones.

Whether or not you need a calcium citrate supplement will depend on your daily diet. As a general guideline, adults need 1,000 mg of calcium everyday. This number goes up more with age. Men over 70 years of age and women over 50 years of age should aim for 1,200 mg of calcium everyday. Splitting the amount of calcium you take per day is also more beneficial than taking it all at once.

You also want to make sure your calcium intake is not too high, as this could be associated with a risk of heart disease. That is why it is always recommended starting with a small dose and building up gradually. But always make sure to confer with your health professional or physician first. With calcium citrate, you will find that there is less constipation, gas, and bloating, than with calcium carbonate. For this reason, we’ve listed ten excellent calcium citrate supplements you can take.
