This multifaceted vitamin is important for strong bones, healthy cell division and growth, immune function, insulin secretion, blood clotting, and blood pressure control. But wintertime deficiencies of this vitamin are very common in North America. That’s why it’s important to take steps to boost your levels year round by supplementing with the superior vitamin D₃ form. Of course, I’ve included Vitamin D in my Forward Plus Daily Regimen multinutrient, and it is a core ingredient in Omega Defense, a next generation supplement for complete cardiovascular, metabolic, brain and cognitive health.
