Why You Should Take Calcium Twice, Daily

Treatment / December 2, 2014

Lara Pizzorno is the author of “Your Bones: How You Can Prevent Osteoporosis and Have Strong Bones for Life – Naturally” and a member of the American Medical Writers Association with 29 years of experience specializing in bone health.

Recently we asked Lara if she would help us provide a series of short, ongoing videos to help you (our customers and readers) stay up to date on the latest facts and science related to bone health and overcoming osteoporosis naturally.

In this latest video, Lara explains why you should take your calcium twice, daily, instead of taking it all at one time.  Watch the video below (or read the transcript provided) and let us know what you think in the comments

 

 

Hello, I’m Lara Pizzorno. Here to try to share information with you that I hope will help you get the most out of the calcium supplements you take.

Some very interesting research has discovered that we absorb more calcium when our need is greatest and the amount consumed at one time is lower.

So the takeaway from this research which I’ll explain in a minute is that you want to take your calcium supplement in a dose of about 350 mg twice daily.

The reasons for this was dramatically shown in a study that compared the bioavailability and the absorption of calcium from calcium carbonate or calcium citrate supplements in 37 healthy men and women. Once again, as I’ve discussed in other studies, the absorption of calcium carbonate and calcium citrate was identical when these supplements were taken with a meal. As discussed, calcium carbonate requires the presence of some stomach acid so the calcium can be solubilized and best absorbed, while calcium citrate does not require this. But even a snack will provide you with enough hydrochloric acid for you to absorb as much calcium from calcium carbonate as calcium citrate. The really interesting fact revealed by this latest study is that more calcium was absorbed when a lower dose was taken at one time.

What they did with these 37 healthy men and women was they gave either a 1000 mg dose of calcium at one time or they gave 300 mg doses, twice daily. And they found that when 1000 mg was taken all at once, the subjects only absorbed 28.4% of elemental calcium from the dose. But when a 300 mg dose was given, they absorbed 36% of the calcium from that dose. And the researchers then determined that the maximum dose of elemental calcium that should be taken at one time, for the best absorption result, was 500 mg, no more than 500 mg. And that a dose of about 350 mg taken twice daily, is likely to provide the best absorption of elemental calcium from a supplement via calcium citrate or calcium carbonate.

I hope this helps you get the most out of your supplements, whichever form of calcium you choose to use. Thanks for tuning in!

So which one is in the algaeCal? Calcium Carbonate or calcium Citrate? Which one is better for you? She does not tell us!

Hi Zeegee,

Great question! AlgaeCal is not just calcium, but a complete multi-mineral. We have had a lab analyze the calcium types with 4 different calcium forms identified (calcium hydroxide, calcium sulphate, calcium phosphate and calcium carbonate). Besides the calcium forms, there are 13 other bone supporting minerals naturally occurring in AlgaeCal which are more likely the cause of the extraordinary clinical results.

We have just posted a new video where Lara reveals which calcium form is best. You can watch it here: https://www.algaecal.com/blog/calcium-proven-increase-bone-density/

Hi.
I am a 64 year old female who just found out last week that I have Osteoporosis. Actually, I found out from the woman doing the DEXA scan. I see the doctor today for the scoring. My doctor wants me to take 1200 IU of Calcium per day, and 800 IU of vitamin D 3 a day. I ordered the AlgaeCal Plus and the Strontium Boost and should be getting them soon. How many of the AlgaeCal Plus and Strontium Boost do I take a day to get the required dose that my doctor wants me to take?
After doing a lot of reading on the pros and cons of Osteoporosis medicines, I have decided that I am going to do this naturally if possible, which I know is going to irritate my doctor. We all have to do what we feel is in our best interest for our own bodies and well being. I haven’t taken Calcium for about 10 years, and the last time was Coral Calcium. Within a few months after taking it, I developed kidney stones and so did my sister. We both feel that it was from taking “the rocks” as they are called on here. I hope the AlgaeCal doesn’t do that! Thanks.

Hi Karla,

It’s great that you have done your own research and have decided to go as natural as possible!

For bone growth, we recommend taking four capsules of AlgaeCal Plus per day (two at breakfast or lunch and two at dinner). This will provide you with 720 mg of elemental calcium. In addition, The Standard American Diet also provides you with an average of 500 mg of dietary calcium per day. In total, you will reach your 1200 mg of calcium per day just as your doctor wants. As for vitamin D3, four AlgaeCal Plus capsules will provide you with 1600 IU per day.

With regards to AlgaeCal and kidney stones – studies suggest that calcium from food sources do not cause kidney stones because they contain other minerals to help the body transfer the calcium to the right place, your bones, instead of soft tissues like arteries, kidneys etc.

If you have any more questions, please do not hesitate.

I am interested in this product. My doctor wants me to take 1800 iu of calcium a day along with 5000 iu of D3 a day. I am on Synthroid, so can’t take anything with calcium within 4 hours of taking it. ( I take it first thing in the morning) How do you suggest using your product?
Thank you

Monica

Hi Kay,

It is recommended to take 4 capsules per day, unless you don’t eat any dairy, then 5 capsules per day (2 or 3 at lunch and 2 at dinner). Taking 4 capsules will provide you with 1600 IU of vitamin D3 and 720 mg of calcium per day. You can supplement with extra vitamin D3 to meet your recommended 5000 IU per day.
