Scientist-formulated dietary supplement designed to boost Vitamin D levels while supporting strong bones and a healthy immune system.
Vitamin D3 is essential for maintaining overall health. It helps the body absorb calcium and phosphorus, which are critical for building and preserving strong bones and teeth. Beyond bone health, D3 supports immune function, muscle strength, and mood regulation.
Deficiency in vitamin D3 can lead to weak bones (osteoporosis, rickets), higher risk of infections, fatigue, and even cardiovascular or metabolic issues.
Vitamin K2 plays a crucial role in calcium regulation. It activates proteins (like osteocalcin and matrix Gla-protein) that direct calcium into bones and teeth while preventing it from depositing in arteries and soft tissues. This dual action strengthens the skeletal system and protects cardiovascular health.
Vitamin D3 and K2 work synergistically to optimize calcium use in the body. D3 enhances calcium absorption, while K2 directs calcium into bones and teeth, preventing it from depositing in arteries and soft tissues.
Together, they:
- Strengthen bones and reduce fracture risk
- Protect cardiovascular health by preventing arterial calcification
- Support immune and metabolic function
- Promote overall longevity and vitality
D3 + K2 improve bone strength, heart health, and immune balance more effectively when taken together than individually.

Dr. She built his career studying how cells age and decline.
His research revealed a troubling pattern. Most people live 80 years but stay healthy for only 60.
That 20-year health gap became his focus when he founded Jinfiniti to bridge this gap with science.
“Aging happens at the cellular level. When we can measure it, we can address it.”
Dr. She’s method is simple. Test your biomarkers. Target what’s declining. Track your progress.
