Kirkman offers hypoallergenic calcium with vitamin D in 200 mg strength capsules. This product is part of their Bio-Max series that uses forms of nutrients that have been clinically proven to be among the best absorbed and most highly bio-available.
Kirkman's calcium capsules utilize calcium bisglycinate amino acid chelate, which has been demonstrated to have superior absorption qualities. The following chart published by Albion® Labs, Inc., the manufacturer of this calcium, shows this by comparing the absorption percentages of different calcium sources:
Source - Absorption % Rate
Carbonate - 23%
Citrate - 25%
Milk - 27%
Hydroxiapatite - 17%
Bis-glycinate chelate - 44%

This form of calcium is not used in our powders because it has an unpleasant taste. For this reason, we suggest that the capsule be swallowed whole and not opened to mix with food.
