D3 plus MK-7, the bone and arterial calcium routing pair.
K2 activates osteocalcin, the protein that binds calcium into bone matrix. Without K2, calcium absorbed via D3 has no targeting signal.
K2 activates matrix Gla protein, which keeps supplemental calcium out of arteries and soft tissue, addressing the cardiovascular concern around isolated D3 use.
D3 is essential for immune cell function. Adequate serum D3 supports the response to viral and bacterial challenges, particularly through winter.
From April to September in South Africa, UVB exposure drops and indoor lifestyles take over. Daily D3 closes the gap most adults hit.

Natra Heal SA
South African adults wanting daily bone, immune, and cardiovascular support, particularly through winter when UVB exposure drops. Particularly useful for those over 40.
D3 alone raises calcium absorption but does not tell it where to go. Adding K2 (MK-7 specifically, with its longer half-life) directs the calcium to bone rather than arteries. Always take the pair, not just D3.
Take in the morning with a fatty meal. Both D3 and K2 are fat-soluble, and breakfast typically contains the day's first fat intake.
Take 1 tablet daily with water and a fat-containing meal. Use consistently year-round, especially through the South African winter.
Strategic Cross-Sell
Magnesium is required to activate vitamin D3 into its hormone form (calcitriol). Pairing D3+K2 with magnesium completes the bone and cardiovascular trio that all work together.
