180 capsules (30-day supply)


An all-inclusive bone-building formula

Osteo-Key contains:

  • The most absorbable form of calcium available
  • Complete vitamin K complex + added vitamin D3
  • Bone-building minerals magnesium, silica, boron, manganese & zinc

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.

I subscribed for Osteo-Key due to significant osteoporosis in my family. Now I have Osteopenia. I’m hoping my next DEXA will reveal improved bone. I’ve had great success with UNI KEY products Thank You

this gives you constepation

This made me constipated.

UNI KEY Health

Hi Alison, Thank you for your review. Osteo-Key does contain vitamin D which can cause constipation at high levels. Taking the recommended dose of 6 capsules per day would only give you 1200 IU of vitamin D and is not considered a high dose. We're sorry this is an issue for you. We're happy to uphold our 90 day money back guarantee. Please call our office at 800-888-4353 for more information. In good health, UNI KEY Staff

Afraid to stop

I performed a test for myself. I have osteopenia and when I started taking Osteo Key I stayed on it for a full year and when I had my bone density test, I returned to my doctor she said keep doing what you’ve been doing. My condition did not deteriorate in that year. So I DON’t want to go off of that supplement.

Best mineral supplement

This supplement is very easy to use—gel caps, not some giant horse pill that I cannot swallow and might not be able to digest. This is easy on my nervous digestive system and seems more calming and sleep inducing than magnesium alone. It has all the important co-factors to calcium that make it ideal for older women with osteoporosis like me.

Wonderful product

I was diagnosed with osteopenia several years ago. I started using Osteo-key about 3 years ago. I went for my Dexa-scan last month and still maintaining a good reading for osteopenia. I believe it is the K vitamins added to the calcium. My GYN never knew K was an important addition in helping prevent osteoporosis! We need to educate our physicians.
