Calcium is the most popular mineral supplement on the market, yet certain calcium compound in tablet form are often poorly absorbed by the digestive systems of older people. The Life Extension Foundation Buyers Club supplies calcium supplements and almost all other mineral only in the form of finely divided mineral powders within capsules that easily disintegrate in the stomach for optimal absorption. Studies have also shown that certain compounds of some minerals are absorbed better than others.

Calcium is the most abundant mineral in the body where it is primarily found in bones and teeth. In bone formation, calcium forms crystals that provide strength to maturing bone. Peak bone mass is usually achieved when people are in their twenties.

Benefits of calcium supplements

Calcium is needed for more than just healthy bones. It is also important for muscle contraction, blood vessel contraction and expansion, the secretion of hormones and enzymes, and sending messages through the nervous system. A meta-analysis of 56 clinical trials demonstrated a significant impact on heart health resulting from increasing calcium intake by 1000 to 2000 mg/day. In addition, recent evidence suggests that increased intake of calcium may help in weight control as well.

Calcium and other minerals are best not taken with fiber, because fiber can interfere with their absorption. There is evidence that calcium supplements and dairy foods may inhibit iron absorption, although it has been very difficult to distinguish between the effects of calcium on iron absorption versus other inhibitory factors such as phytate.

Therefore, if you are iron deficient, it may be best to avoid taking calcium with meals. Calcium supplements are best administered at dinner and/or bedtime. They should always be taken with a full glass of water, juice, or other liquid to enhance solubility. If calcium supplements are taken only once daily they may be best taken in the evening.

Calcium supplements and your bones

Calcium is an essential mineral that is often inadequately supplied, inefficiently absorbed, or excreted faster than it is being assimilated. The citrate salt of calcium has been documented to be well absorbed and utilized by the body. This is the form many doctors and nutritionists recommend. Calcium citrate dissolves easily even if one doesn’t have much stomach acid. Many people naturally produce less acid as they age, so calcium citrate is a good choice for older adults. Also critically important is the addition of vitamin D3 which stimulates calcium absorption and promotes healthy bone density.
