Superior absorption in a vegetarian form!

Bone constituents are constantly recycled in the body while new bone is made. In fact, every bone cell in our body is replaced once every three months. The formation of healthy bone requires the presence of more than 18 different essential nutrients and probably many more as yet unidentified as essential. That's why it is important to think of bone health as requiring a whole lot more than just calcium.

Suggested Usage: Take 2 tablets twice daily.

• Calcium carbonate is the form of calcium found in chalk, Tums, and many inexpensive supplements.  Its advantages?  It's cheap, and you can fit a lot of it in a pill.  It's disadvantages?  As an antacid, it may compromise digestion, potentially leading to a number of problems, not the least of which is constipation.  Also we need adequete stomach acid to absorb it.  If taken on an empty stomach, or by someone using acid-blocking medications, it will absorb poorly.
• Calcium citrate is considered a more "premium" form of calcium.  You can fit less of it in a single pill than you can calcium carbonate, but it absorbs better and does not impair digestion.  Although less well known, calcium lactate, gluconate, aspartate, malate, and chelate are all probably as good.
• Calcium hydroxyappatite (MCHA) is very absorbable and fairly economical.  It is highly recommended, but it is derived from cow bones, so not suitable for vegetarians.
