Are Calcium Supplements from Algae Better?

Q: Are calcium dietary supplements derived from algae higher than different sorts of calcium, as marketed?

A: We’ve seen no good analysis to assist the claims. A number of expensive calcium dietary supplements get the mineral from marine algae— that’s, seaweed. Many questionable claims are made in regards to the superior absorption and efficacy of those dietary supplements for bone well being. Their primary message is that “plant calcium” is healthier (“extra physique pleasant”) than normal calcium that comes from “rocks,” though all calcium may be traced again to the earth’s crust (that’s, rocks).

These dietary supplements additionally comprise different minerals naturally within the seaweed (akin to magnesium) and infrequently different added bone-health vitamins (akin to nutritional vitamins D and Okay, boron, strontium, and numerous hint minerals).

The research cited by the producers, most funded by them or involving researchers employed by them, show little or no since they don’t embody a comparability group (utilizing both a placebo or different calcium complement), and the modest enhancements in bone mineral density might have been as a consequence of different vitamins within the complement, as an example, or to the additional train the themes undertook. Different analysis cited was executed in labs on remoted bone cells or in mice and should don’t have any relation to what occurs in folks.

We will’t suggest algae-based dietary supplements over normal types of calcium, since there are not any well-designed research evaluating them when it comes to efficacy and security. It’s unimaginable to know what impact, if any, the extra vitamins within the dietary supplements have. There are numerous different “bone well being” formulation on the market, containing all the pieces however the kitchen sink and making related claims—with no convincing medical assist.

Get as a lot calcium out of your food regimen as potential, and in case you fall quick, keep on with calcium carbonate or calcium citrate dietary supplements. And think about taking a separate vitamin D complement.
