AdvaCAL is the only line of calcium supplements with AAACa calcium, the #1 boneābuilding calcium. AAACa, a patented ionic calcium, has shown statistically significant improvement in bone density in four published human studies. Participants in that research included women and men in their 60s and women in their 80s. In those studies bone density improvement started as early as 4 months, up to 3 years. The average increase over placebo ranged from 2.6% to 3.3% per year in long term studies.*
