Bioavailability is the rate at which a drug or supplement gets absorbed by the bloodstream and is made available to be used by the body. Bioavailable calcium sources are calcium carbonate, calcium citrate, calcium acetate, calcium lactate and calcium phosphate.
Out of these calcium carbonate provides the highest concentration of elementary calcium when consumed. Bioavailability of this compound is over 95%. Other compounds like calcium citrate and calcium acetate are more easily absorbed and their bioavailability is over 96%.
Bioavailable calcium sources are used to make good-quality calcium supplements. Doctors suggest eating calcium carbonate tablets after meals. This compound is capable of reducing acidity and gets absorbed in the presence of vitamin D and phosphorus. A variant on calcium carbonate known as coral calcium is another natural source of calcium and has a higher rate of absorption than normal calcium.
All the above-mentioned bioavailable calcium sources have shown high absorptability in different patients. Rate of absorption also depends on a person's internal structure, overall health and amount of vitamin D present in the blood. In normal conditions, any of the above-mentioned calcium sources can be consumed to exceed calcium deficiency in the blood.
Elderly people and those who have a sensitive stomach are recommended to try coral calcium supplements. This natural source of calcium not only provides up to 40% of elementary calcium but also reduces acidity in the stomach and makes digestion easy. Coral calcium is obtained from fossil coral reefs and is entirely pure and safe to be used by people of all ages.
Eggshell and oyster shell are also counted as bioavailable calcium sources. A normal, healthy person should consume up to 1200 mg of calcium everyday. To fulfill this requirement add good-quality calcium tablets to your diet. Women above the age of 40 are strongly advised to watch their daily intake of calcium and other nutrients. They require at least 1500 mg of calcium on a daily basis.
Deficiency of calcium can be easily controlled with the help of calcium supplements. A wide range of these supplements are available on the market now. You do not require a doctor's prescription to buy these supplements because the ingredients used in making the tablets are totally natural and clinically approved.
Try to find coral calcium supplements made with Okinawan coral calcium. This special kind of coral calcium is obtained from waters around Okinawa island of Japan and is gaining widespread popularity due to its many benefits.
