Received promptly. Great customer service. I love that.

NBI Osteo-k

The capsules are easier to swallow than most calcium pills. I’m looking forward to the results in taking this particular supplement (which includes mk4 ) on my next dexascan results.

NBI Osteo-K

Seems to be gentle on the stomach, unlike other high strength Calcium blends.
Also, love the ingredients.

Louella B.
Wonderful product.

I have had back issues for awhile now. I started taking Osteo-K a couple years ago. It has been helping my back problems and my knee pain from Arthritis. I will always take this instead of taking prescribed meds! Thank you NBI.

Irene S.

My doctor recommended osteo-k for my bones. I won't know until a year from now when I have my next Dexa-scan if it has helped, so I cant really say if it's working. The only thing I dont like is I have to swallow 6 capsules a day.
