Natural marine collagenic bone powder may increase serum calcium better than calcium carbonate, says recent study

A recent study1 compared the serum calcium levels following consumption of calcium carbonate and natural marine collagenic bone powder made from bone meal derived from Atlantic salmon, called CalGo, which is manufactured by Hofseth BioCare (Ålesund, Norway). In the randomized, double-blind, placebo-controlled study, 12 post-menopausal women between the ages of 55 and 75 were divided into two groups. Group A received four tablets containing 500 mg of CalGo the first day, and the blood was sampled the second day. After a seven-day washout period, the subjects in group A were then given four tablets of 250 mg of calcium carbonate, each, and have their blood samples collected the next day. Group B underwent a similar protocol but in reverse, first receiving calcium carbonate, then switching to CalGo after the seven day washout period.

Results showed that significant increases in serum calcium were experienced when subjects took CalGo, compared to baseline values and calcium carbonate consumption. The day after supplementation with calcium carbonate, subjects saw no significant increases in serum calcium, while 24 hours after consumption of CalGo, subjects saw a significant increase in serum calcium levels by 1.28%.

“At Hofseth BioCare, we understand fresh thinking is crucial to progression and we remain steadfast in our mission to forge a new era in nutrition – one that is sustainable, traceable and most importantly, evidenced and effective,” said Crawford Currie, MBBS, head of medical R&D at Hofseth BioCare, in a press release. “These findings strengthen a growing body of evidence that CalGo is a promising ingredient in sustaining bone health, with both preventative and remedial benefits. Further clinical research studies are ongoing and we are excited to discover the full potential of our naturally-inspired nutritional innovations.”
