Why Should Vitamin D3 Be Taken with K2?
Vitamin D3 and Vitamin K2 work synergistically together. The combination is particularly important after bariatric surgery.
The Role of Vitamin D3
Vitamin D3 regulates calcium absorption in the intestines and is essential for healthy bones, a strong immune system, and muscle health. After bariatric surgery, vitamin D deficiency is common.
The Role of Vitamin K2
Vitamin K2 (as MK-7) activates proteins (osteocalcin, matrix GLA-protein) that direct calcium into the bones and keep it out of the arteries.
The Problem Without K2
When vitamin D3 is taken alone, the increased calcium absorption can lead to deposits in the arteries — a risk factor for heart disease. Vitamin K2 prevents this.
Recommended Dosages After Bariatric Surgery
- Vitamin D3: 3000–5000 IU daily (based on blood values)
- Vitamin K2 (MK-7): 100–200 µg daily
- Calcium: 1200–1500 mg daily (in divided doses)
Important: Regular Blood Tests
After a bariatric operation, vitamin D levels should be monitored every 3–6 months.
