Vitamin D + Calcium
Vitamin D helps your body absorb calcium
How It Works
Vitamin D stimulates production of calcium-binding proteins (calbindin) in the intestinal epithelium, increasing calcium absorption from 10-15% to 30-40%. Without adequate vitamin D, you absorb less than half of dietary calcium.
Pro tip: Salmon + leafy greens covers both synergistically
Best Food Pairings
Pair a vitamin d-rich food with a calcium-rich food.
