Where does Coral Calcium come from?
It's not likely that its use will lead to destruction of coral reefs since much of the coral calcium supplements come from fossilized coral (mostly from Okinawa, Japan) and coral calcium sale is carefully controlled by the Japanese government.

Benefit of Coral Calcium Supplement
Much has been said about this dietary supplement, but in reality little is known about the benefits or risks of coral calcium. I am not aware of any published studies regarding the long term (or even short term) use of coral calcium supplements. If anyone is aware of such studies, I would be glad to review them. I plan to keep an open mind about coral calcium, and will provide an informed opinion as soon as I come across reliable research.

Blood pressure testimonial
Ever since I started taking coral calcium my blood pressure has been normal. Instead of 140/90 now it's more like 120/70. Some times diastolic is 65. Is it OK to have a 60 point spread between systolic and diastolic? I've been lifting weights for 10 years and am 48 yrs. old. I don't know if the weight lifting has anything to do with it? The infamous coral calcium infomercial by Bob Barefoot claims we can avoid many diseases by keeping our blood ph alkalinic through use of calcium and magnesium. This seems to be true in my case because I am rarely sick and now my blood pressure is down.
   In order to better determine whether coral calcium what the factor in the blood pressure drop, it would be a good option to stop taking the coral calcium for a month to see if the blood pressure rises again. If it does, then coral calcium can be reintroduced to see if the blood pressure drops. Another option is to take calcium/magnesium supplements to see whether they alone, without coral calcium, would lead to a similar drop. At this point I don't know if coral calcium is much better than plain calcium and magnesium supplements.

Restless legs syndrome testimonial
I am 38 and have suffered with restless legs syndrome for many years. I wanted to let your readers know that I have found that taking coral calcium before going to bed helps my legs to relax and I sleep great. Also, mangosteen seems to have helped keep the twitches and creepy crawly sensations to a minimum.
   Thanks for letting us know. We will wait to see if others with restless legs syndrome give us feedback with similar benefits in regards to coral calcium or mangosteen.

Coral reefs in danger
The escalating level of carbon dioxide in the atmosphere is making the world's oceans more acidic. By the end of the century, the trend could decimate coral reefs and creatures that underpin the sea's food web. Ocean acidification is one of the most pressing environmental threats facing Earth

Emails
I purchased the calcium supplement sold by Physician Formulas. However, I have long been confused about which form of calcium is 'best'. I am a 40 yr old female, and mother of 2. I have heard of the buzz about coral calcium, but dont think you sell this formula on your website. Is it less effective than the formula you sell? And, what advice / recommendations can you offer me about coral calcium, calcium supplements, and which to choose. I've even spoken to pharmacists to try and unravel the calcium mystery and make the best choice for me. Please feel free to email me personally and to post my question on your website. I bet there are others who are wondering as well.
   A. There is a lot of controversy regarding which form of the mineral calcium is best. Different experts have different opinions. In my judgment, and for practical purposes, I don't think we need to worry about the form of calcium ingested. Overall it probably does not make too much difference. One good option is to purchase a different form of calcium each time you buy a calcium supplement, and this way you could expose your body to the different variations. As to coral calcium, the jury is still out whether if offers benefits to any significant extent than calcium and magnesium supplements. However it is difficult to say since we have not seen any human trials comparing calcium versus coral calcium.

How do you know the Okinawa coral calcium is free of radiation since there was so many nuclear testing going on and near these islands?
   This is not an easy question to answer since different batches of coral calcium come from different areas of the seas each with its own micro-environment that may be quite different than another growth a few miles away. If the basic question pertains to purity of products from the sea, do keep in mind that in this day and age there is nowhere on the planet that is 100 pure. Plus, we need to keep things in perspective. Some people worry about potential low level pollutants or toxins in their foods or supplements not realizing that even taking a quick drive on the road or highway exposes a person to a much higher level of pollutants than potential ingestion of extremely low amounts from certain supplements. Yet, most people don't even think twice about getting in the car for a drive yet worry about other potential exposures that are not as serious. One can live life with less stress when not worrying about being exposed to minute levels of pollutants, otherwise we would be worried on a daily basis and this reduce longevity and quality of life.

Allergy
What about those who are allergic to shellfish?
   As of 2016 I have not seen reports in the medical literature regarding allergic reactions in those who have shellfish allergy but I will look into this more closely. Different companies have different ways of making the final product.
