Calcium bound to citric acid is a well-absorbed form of calcium. Citric acid is a naturally occurring organic acid that is able to efficiently bind three mineral molecules for every one of its own molecules. Studies have shown significantly more calcium is absorbed in the body from calcium citrate than from calcium carbonate. One study found patients with low hydrochloric acid levels absorbed an average of 10 times more calcium from citrate than from carbonate.

This product is best for calcium absorption my doctor said. He is one of the top medical doctors in the country.

I order these from Amazon monthly. I have a dairy allergy and lack the needed calcium for my body. These pills seem to work well but I do hate how easily they break. I would rather take the pill as a whole so I know I'm getting the right amount over broken pieces and playing the guessing game.

2.03cm x 0.9cm in size: TOO BIG TO SWALLOW. Now I understand why he gave me a vague answer when I emailed the question prior to the purchase. Very bad. These tablets are HUGE. You can only take them if you cut them in two, and if you do they are still big to swallow.

I have been taking this brand of calcium for nearly 2 years. I have a corn allergy and other brands who say they're "corn free" have caused a reaction. I found Best Naturals brand and haven't looked back. I buy all of my required supplements (due to medical issues) as well as my preferred supplements from this store. The convenience of the auto-ship BUT with the getting an email so I can add to or change my order or payment method is so helpful. I don't have to worry about running out of stuff that I take all of the time. I don't have any trouble with this calcium. It works well and has helped improve my low calcium levels so I'm in the normal range. Please keep doing what you're doing... making quality (corn free) products.
I have night leg cramps. Using this calcium and magnesium at night stops them. I discovered this on my own.
I like these calcium tablets, plus they’re made in USA. However when I purchased them the 2nd time I received them in a lightly padded mailer pouch. They were broken from bouncing around
Good supplement but beware they are horse pills. Not easy to take with a smart airway. Had to break in half.
Great calcium. I appreciate the quality, corn free supplements I get from Best Naturals. I have a condition that requires me to take calcium every day. This works well and helps keep my calcium levels stable. This gives me what I need without a bunch of extra stuff that I don't want.
Made in America as far as I can tell. This calcium is supposedly good for the bones.
trying to save money buying in bulk but many in both bottles are crushed. I am having trouble returning for replacement as the pictures im sending they apparently aren't receiving, have never had any issues sending pics before. Sent pictures of the lot number, expiration date, receipt, and damaged pills. this is frustrating because she needs multiple pills daily and is now out. So I'm going to have to drive 20 miles to buy the same thing I was trying to replace. I've never had issues before online but I'm not going this route again. If you're willing to take the chance and it works for you you'll save money but it's going to cost me more than getting these for her through her pharmacy. If issue is resolved I will definitely post results for them
