Winter in Alberta often results in widespread vitamin D3 deficiency, making Ortho Molecular’s D3-K2 supplement an invaluable solution. Vitamin D3 is vital for calcium absorption, strengthening bones, and fortifying the immune system. This supports cardiovascular health, bone density and enhances immune function for infection defense. Importantly, research suggests combining D3 with an oil like coconut oil improves absorption and bioavailability. Tablets are not recommended as they prove ineffective in altering D3 blood levels, unrelated to their fat source.
