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.

Osteo - Key

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!

more flexibility

I've been dealing with stiff tight ligaments behind my knew for 18 months since my right total knee replacement in June 2019. I'm still seeing a PT who practices dry needling, deep massage work, cupping etc, and I' also see a therapist for Myofascial release, among other alternative treatments. I started taking Osteo-Key on a Tuesday and realized after a few days climbing stairs was easier and my lower back pain was minimized. I only take 1 or two capsules a day but I've noticed a definitive improvement in my movements.

I have had problems in the past with calcium supplements making me constipated. This formula is great. I had no issues and have been taking it for a month now. Great product!

Osteokey prevented a surgery!

My grandson broke his tibia, fibula, and ankle, last September. The front of his shin wasn’t closing all the way, so the doctor wanted to do a bone grafting. She said she would wait a month so we could try supplements. I gave him Osteokey and today he had an X-ray, and he is 90% healed. The doctor canceled the surgery. I gave her the website, because she has another patient who isn’t healing properly, and she wants the child’s parents to buy it for her. The doctor was floored at the results. She is an orthopedic surgeon at the Children’s Hospital of Philadelphia.
