HIGH Calcium Content
Great and effective product! I’m really impressed by the calcium content in just two small pills. I’ve heard great things about the effectiveness of nano calcium and my friend who has taken this product for a couple years recommended this to me. The product came in a timely manner and the pills are easy to take. Excited to receive all the benefits this product has to offer!

It works for my joint problem like no other.
I’ve had chronic shoulder scapula problem that I go see pain management doctor for. there is no home-run type surgery available for me and the medicine that doctor prescribe doesn’t really help with the pain. I started taking this nano calcium supplement and my scapula pain is significantly gone. i’ve been taking this for over 6 months and my pain level compared to before I started taking is like night and day. I know this is quite pricey for calcium supplement, but if you are suffering from day to day joint pain and problems, this is so worth getting.

Seems to do the job
I don’t like capsules, they tend to float to the top of my stomach and open causing dyspepsia; however, I’ve learned to eat a little something before AND after taking them which helps. Bought these because my fingernails were getting very thin (and feared the same was true of my bones) as a post-menopausal woman I was concerned. After 2 bottles of Bonstrong there has been a definite difference in my fingernails (stronger and thicker) so hopefully in my bones as well!

No longer recommend
I’ve ordered the Nano Calcium supplements in the past and have been very happy with them. I appreciated the combination of vitamins and minerals that, it’s my understanding, make the calcium more readily available for absorption. My GP Dr. agreed – a good product for my needs. However, this last order upon opening the bottle the odor was repulsive. The pills themselves have changed as well, they are smaller. Something has changed with this product and not in a good way, in my opinion. I can no longer recommend it. I will be looking for another calcium product to purchase. UPDATE: After providing my review (above), this company reached out with apologizes and provided a full refund. Great customer service!!

Wonderful results! Highly recommend!
I have been taking this for 8 months. Today I saw my rheumatologist and had my yearly bone scan. For the past several years I have had a steady decline in bone density even with a prescription for a bone density drug. I’d been told that I was facing another medicine, which would have been an infusion if my bone density declined again. Well, it did not decrease, but I had a 5.8% increase. My doctor said keep this up! I am so excited about these results. Telling my other friends that suffer from osteoporosis.

Easy on the stomach.
So far this stuff is the best that has ever worked for me. I have more energy. My bones feel stronger and I just feel better all the way around. This is the best bone supplement I’ve ever had.

Positive Results After One YearPositive Results After One Year
I’ve been taking BonStrong for about a year after being diagnosed with osteoporosis in my hip and cervical spine. Before starting it, I discussed this supplement with my doctor and showed him the calcium product I planned to use. Although the label recommends two capsules daily, he advised me to take one capsule a day based on my individual needs.Since adding it to my routine, my calcium levels have improved, and my follow-up evaluations have been encouraging. I was also concerned about excessive calcium supplementation, but so far I haven’t experienced any issues related to calcium buildup.Of course, everyone’s situation is different, and this is just my personal experience. For me, this supplement has become an important part of my bone health plan. The capsules are easy to take, and I intend to continue using it. Five stars

Good option for parentsGood option for parents
Picked this up for my parents since they’ve been paying more attention to bone health lately. I heard good things about nano calcium and thought this would be worth trying for them. They’ve been taking it daily and seem really happy with it so far.
