Frequently Asked Questions

Where is bonstrong nano calcium made?

All of our products are made and packaged in the United States in Los Angeles, California at a certified nutraceutical manufacturing factory.

Our product, especially the technology used to create nano-sized particles, is designed and developed in South Korea.

Does BonStrong Nano Calcium contain any artificial ingredients? 

Outside the ingredients listed in the Supplement Facts, only vegetable gelatin is used to create the capsules themselves.

There are NO artificial colors, flavors, preservatives, chemical solvents, yeast, starch, or gluten.

It is lead free and GMO free.

How many pills are included in one Bottle?

Each bottle contains 120 pills, which is a one month supply.

  • One Month Supply: 120 Pills
  • Two Month Supply: 240 Pills
  • Three Month Supply: 360 Pills

How should I take the pills?

Please take 2 capsules, twice a day, with a meal. That equals 4 capsules a day.

Spreading out the ingredients in smaller dosages in this way allows each nutrient to be the most effective and puts less stress on your body.

For best results, we recommend you take it once during breakfast and once during dinner.

Why is there only 320mcg of calcium?

With calcium, more is definitely not better. All doctors agree that the body cannot consume more than 500mcg of calcium at a time. Therefore, taking more is actually not only wasteful, but harmful to your body. Excess calcium buildup is the main reason some people experience stomach aches and other side effects.

As Nano-Calcium is fully absorbed, we are able to better control exactly how much calcium you should take. Therefore, we prescribe 320mcg per serving. Taken twice a day, as recommended, would result in 640mcg per day. We assume most people will consume at least some calcium through their normal diet, and this will result in the full recommended amount of 1,000mcg to 1,200mcg per day.
