Notice the many people claiming to be ‘health experts’ these days, all with varying advice? It’s exhausting knowing who and what to believe, as they seem to present equally compelling evidence for their case. So in the rare moment they agree on one thing, I take note because I think it may be an example of that elusive thing we call ‘The Truth’.

Vegetables: The One Thing All the Experts Agree On

Have you ever heard any diet plan, or person recommending that you stop, or even moderate your consumption of broccoli, kale or collard greens? 

No, but the merit of steak, rice, bread, cheese, fish and more, is always being debated, with even the advocates advising to limit your amounts.(1) 

That vegetables are just good for you is unanimous even amongst the most opinionated nutritional authorities.

And there are many brands and types of calcium supplements that are constantly debated by the experts. Of the hundreds available, 90% are made from limestone rock because it’s cheap. And in lesser amounts are calcium products made from coral, animal bone, egg and oyster shell.

Limestone calciums (labelled as ‘calcium carbonate’, for greater appeal) are popular for their cheap price, but in the last couple years published studies revealed they lead to increased risk of heart attack.(2)

Then coral calciums were in vogue as they contain many trace minerals that we need. But the massive ecological devastation of coral harvesting came to light, so people turned away.

Oyster, eggshell and cattle bone calciums

 also had their time in the sun, until critics pointed out various problems with these animal based products such as absorption. But a bigger downfall is that (just like with coral and limestone calciums) they are only able to slow down your bone loss.(3)

Is There A Calcium Supplement Experts Agree on?

Thankfully there is agreement between the authorities on something, and that it’s calcium from vegetables, not rock (or bone or shell) that works best. No big surprise really, because it’s known we absorb and digest the minerals and vitamins from vegetables much better than anything else.

And AlgaeCal

 is the only available calcium supplement that is made from USDA certified organic vegetables. That’s right – it starts with tennis ball sized ‘macro’ algaes that are hand harvested from the shores of South America for their super high calcium content (triple the amount of common vegetables, like broccoli) as well as for the many trace minerals they contain. The algaes are then dried and milled into powder.

The next step is vitamin D3 and vitamin K2 are added, as both are crucial for the calcium to fully absorb and reach the bones where it’s needed. Both vitamins are absolutely necessary to keep calcium out of the arteries and soft tissues, where you definitely don’t need it!

The Best Bang For Your Buck?

Sure, you can easily find much cheaper calciums. But they at best will only slow down your bone loss – and at worst increase your chance of heart attack!

AlgaeCal costs more than other calcium products because these rare algaes are traditionally harvested one by one, only in small batches, to ensure sustainability. But it’s a case of getting what you pay for, as only AlgaeCal is clinically supported to increase your bone density.(4)
