Choosing a Safer Calcium Supplement

Does it really matter which calcium supplement you take? They’re all the same, right? Well, it turns out that calcium supplements have been linked to increased risks of heart attacks and kidney stones.

Watch the video below to find out which forms of calcium are better, and which ingredients can help.

Here’s What It Takes To Get Calcium From The Bottle To Your Bones (Without Clogging Your Arteries Along The Way)

1. A safer, better absorbed form of calcium. Most major supplement companies use either dangerous carbonate or citrate forms of calcium. Despite the fact that every single study showing an increased heart risk was conducted using these forms of calcium. Yet by going one step further and adding a simple chemical compound to calcium citrate (malic acid), the resulting Calcium Citramate becomes 30% more absorbable than citrate alone.

Calcium Citramate has been shown to decrease fracture risk, increase bone density, and even reduce the risk of kidney stones. And it has never been implicated in an increased heart risk.

2. Vitamin D3. Calcium has no chance of absorption without the presence of this vitamin in significant amounts. Never settle for less than 600 IU in a serving and absolutely never accept the lesser form known as D2. (If the bottle doesn’t say, it’s probably D2 – which is much cheaper.)

3. Magnesium in the correct ratio. Magnesium is critical to over 200 bodily functions, including many involving bone metabolism. Some researchers think it may be even more important to bone health than calcium. Unfortunately, it will compete with calcium for absorption unless taken in the correct ratio. Make sure you have 2 parts calcium to 1 part magnesium in any supplement you take.

4. Vitamin C. The presence of Vitamin C significantly increases the amount of calcium absorbed by your body. It’s also been shown to reduce the rate of bone loss and help maintain healthy bone mass. 

5. Vitamin K. No other vitamin is more crucial to bone metabolism than Vitamin K. It’s the substance your body uses to grab calcium and move it to your bones where it’s needed. In fact it’s so effective that it has even been shown to reduce existing buildup of calcium from arteries by as much as 37% in six weeks. Pretty good news if you’ve been taking a major calcium supplement up till now.

6. Lysine. Another problem with unabsorbed calcium is kidney stones. Lysine has been found to increase the amount and speed of calcium absorption, reduce the amount excreted in urine, and stimulate cells responsible for bone formation.

    I’m currently taking a calcium product put out by Nature City that boasts that it is safer because it is a plant based calcium. Is there any truth to this claim? Is it safer and more absorbable? I just found this site today and am wondering if I should be switching products. I’d love to get your opinions on the Nature City product.

      Hi Scribbler! I did some digging on algae based calcium, the calcium used in Nature City’s calcium supplement “TrueOsteo”, and do you know what I found? Nothing. There is not a single thing I could find in regards to true, scientific studies about this calcium form. The only information you will find on it is coming from companies trying to sell it. That, my friend, is no good to me. Whether it is even good for you, or simply even safe, is up in the air. There were some comments about algae based calcium being similar, or the same as, calcium carbonate which has plenty of studies behind it showing it to be a very inferior form of calcium and hardly absorbable in the human body. Not to mention that most of the marine based calciums may contain toxic contaminants from the Ocean creatures it came from. I can’t imagine an algae based calcium being much different from that.

      Now, calcium citramate does have scientific studies to back it up. It is more bio-available because it is water soluble, and it releases calcium ions and a calcium citrate complex. The calcium ions are absorbed directly into the cells of the intestines, and the citrate complex passes into the bloodstream through passive paracellular absorption. This is a better method of absorption as it doesn’t require energy from the body.

      Conclusion? Due to the lack of research, or at least available research and scientific studies, I couldn’t consciously recommend an algae based calcium.

      I hope this was helpful!
