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.

Helps me sleep

I take 2 Osteo Key every night before going to bed. I notice what a difference it has made in my sleep. I used to get bad cramps in my legs while sleeping. They have stopped since taking Osteo Key. From the very first night. Thank you so much for your wonderful products.

Bones cracking less and finger nails are strong again!

Bone density scans and tests for osteoporosis don't reveal the whole truth about your skeletal system's health. The bones of my extremities have been cracking for years, and my fingernails more recently have been thin and breaking more frequently. I was on Osteo-Key for more than a month before noticing less bone cracking and all of a sudden, my fingernails are thicker and strong again! The vitamin K2 complex is a must for older people and UniKey's formula is the one I trust to keep my bones and nails healthy!
