The Complexity of Calcium

Algae from the Sea

Amazon Elements Calcium Complex contains calcified red marine algae harvested off the coast of Iceland. Calcium is often derived from hard minerals, but our formulation uses marine algae from the Lithothamnion subspecies genus. Because our Calcium Complex is plant-based, the magnesium in our formulation is naturally occurring. Once the calcium is fully cleaned, screened, and milled it is delivered to our manufacturer and used as the active ingredient in our product.

4Seemingly Good Quality Calcium Supplement-But Uses Vitamin D2 & Unsure How Calcium From Marine Algae Compares To Other Calcium
By Robin
This Amazon Elements calcium supplement is a plant based supplement. One serving is three capsules daily and provides 750 mg of calcium as Lithothamnion from marine algae, 600 IU of Vitamin D2 as ergocalciferol from cultured yeast and 50 mg of magnesium as Lithothamnion from marine algae. I've read calcium should be taken in doses under 500 mg at a time with 4 hours between (per Livestrong) so I split mine into two doses. Like many supplements, I can't really evaluate how well this calcium is absorbed and any benefits to my body in the short run. I can say the capsules are easy for me to swallow and digest. I don't have any side effects, such as an upset stomach or any burping up. This seems like a good quality supplement that's vegan, gluten free and free of artificial junk, plus it's been tested thoroughly for metals and impurities that are fully disclosed.

I wish I knew with confidence how calcium from marine algae stacks up against other calcium types. I've read it's basically the same as calcium carbonate, except it has additional minerals that may enhance bone absorption and have other benefits. It sounds good, though it sounds like not enough testing has been done in humans. A 2016 BerkleyWellness article concludes, in short, that there isn't yet enough unbiased evidence about the efficacy and safety of supplementing with marine algae over other types of calcium. This supplement includes 600 IU of Vitamin D2- which I assume is included because Vitamin D aids calcium absorption. Notably, the label says that's 150% of the RDA, but it seems mistaken as Mayo Clinic and other sources say the RDA for D has been raised to 600 IU (so I believe 600 IU is 100% not 150%). Also, one shouldn't assume this calcium supplement with 600 IU of D2 is also an optimal Vitamin D supplement because it's not- it's a calcium supplement with some Vitamin D.

Dr. Weil and others recommend 2000 IUs of Vitamin D3 as cholecalciferol daily (even for vegans) as Vitamin D deficiency is common and Vitamin D3 has many benefits and is superior to D2. I have a strong preference for taking D3 over D2 and take an extra 1000-1500 IUs of D3 as cholecalciferol daily while taking Amazon Elements calcium. I'd prefer this supplement had D3, but also understand vegans and others may not take D3 as cholecalciferol because it's derived from lanolin from sheep's wool. For vegans and those who can't take D3 as cholecalcifero, an additional D2 supplement of about 1400 IUs (unless a doctor says differently) should be taken while taking this calcium supplement. I rate this supplement 3.5 stars (rounded to 4 stars) as it seems like a good quality supplement, though I'd prefer a D3 version. Also, while I think calcium from marine algae sourced from Iceland sounds potentially excellent, I'd like to see more studies confirming benefits by comparing this form of calcium to other types or placebos in humans.
