Bone loss is not simply a "calcium deficiency disease"...

Bone loss is a rather complicated condition that affects an estimated 34 million at-risk Americans. After age 30, breakdown of bone outpaces production of new bone.

Thanks to the latest research on the roles of vitamin K and vitamin D, we can now be assured that the calcium we consume ends up in our bones, not in our soft tissues or arteries.

Other bone loss factors include:

  • Genetics
  • Menopause and hormonal imbalances
  • Vitamin and mineral deficiency
  • Medications
  • Caffeine
  • Alcohol

Our Osteo-Key Formulation

A formula based on the latest research, Osteo-Key contains a complete vitamin K complex (vitamin K1 and two forms of vitamin K) balanced for maximum bone strengthening support capability and increased vitamin D3.*

The Osteo-Key formula provides a clinically effective combination of other supportive bone-building nutrients at the recommended levels:

  • Microcrystalline Hydroxyapatite (MCHA) - provides the most absorbable form of calcium available*
  • Vitamin D3 and complete vitamin K complex - helps transport calcium into your bones for maximum density.*
  • Magnesium - contributes to bone mineral density, deficiency may lead to osteoporosis*
  • Silica (silica dioxide) - stimulates the activity of osteoblasts-the bone-building cells. A recent study of 2,800 participants found that those who supplemented with silica experienced higher bone density.*
  • Boron - helps improve bone strength and preserve bone mass. It also helps the absorption of calcium, magnesium and vitamin D into the bones.*
  • Manganese - promotes the growth of healthy bone and cartilage. Studies show that low levels of manganese can lead to weaker bones.*
  • Zinc - helps to prevent brittle bones. Studies show that zinc is important for proper bone formation, bone growth and mineral uptake.*


Take three (3) capsules twice daily with meals as a dietary supplement.

Healing magic in a bottle

There are a few Unikey products I can’t live without and now I’ve added Osteo-key to my list of essentials! I broke the metatarsal bone in my foot 6 weeks ago. After 3 weeks the X-rays showed no healing. I needed something other than vitamin D and I remembered the Osteokey I took a ways back and immediately ordered a bottle. After taking for 2 weeks the Dr said my foot has healed 50%. I’m on my second bottle and have an X-ray in 2 days and I’m hoping it is 75% or even higher! I want out of the boot and back to doing the athletics I love to do. This is the BEST bone supplement out there!

Osteo-Key is made from the most absorbable form of calcium available and has bone building minerals like as magnesium, boron, zinc and manganese so this makes perfect sense! We hope you're back to your regular activities soon! Thanks for the great review and your support! In good health, UNI KEY Staff

Excellent bone healer

I broke the metatarsal bone in my foot almost 5 weeks ago. The X-ray after 2 weeks after showed no healing and possible surgery. I was discouraged so I doubled up on vitamin D ( which I purchased the Thorne vitamin D from unikey to get a quality product) and also got the Osteo-key and have been taking it 3 x a day. I had an X-ray again after 2 weeks and the Dr was thrilled because it is 75% healed and I’m ahead of schedule and won’t need surgery. I showed him the osteo-key and he said keep taking it because it’s working. Needless to say I bought another bottle! Unikey products are like no other!

I'm a believer now!

I was in a lot of discomfort with my hips, so much so, that I'd see my chiropractor weekly and eat arnica like it was going out of style! After speaking with Liz and reading the reviews here, I thought I'd take a gamble to see if this produce would provide me with some much needed relief. I was astonished! I started to hike again and I slept better, because my pain would keep me up during the night. My body felt terrific and I felt like I lost years -- young again. I really noticed a difference when I ran out of Osteo-Key. It's been out of stock now, for several months, and I noticed a big difference. I cannot wait to reorder Osteo-Key, especially now that winter is right around the corner. I'm hoping to have a pain free winter.

I have been using Osteo - Key for a number of years. I feel, as with all unikey products, that only the the most natural ingredients provide the best results.

Amazing Osteo-Key

Osteo-key healed my grandson’s tibia, to the point that he no longer needed a bone grafting operation. This happened in only one month’s time!
