Buying Guide

Match nutrients to your goals

Choose formulations aligned with specific needs like vitamin D+K for bone and vascular support, K2 for bone health, or collagen for skin and joint support

Check active doses and forms

Look for effective forms and doses—MK-7 or MK-4 for K2, D3 for vitamin D, and clinically used collagen peptides or targeted botanicals for hormone support

Prioritize third-party testing

Prefer brands that disclose independent testing or purity practices to reduce risk of contaminants and ensure ingredient accuracy

Consider synergistic combos

Blends like D3+K2 or collagen with magnesium can improve absorption or support complementary pathways for bone, cardiovascular, or skin health

Watch allergen and dietary labels

Check for soy-free, vegan, or other labels if you have dietary restrictions; some K2 and kids' formulas target those needs
