Buying Guide: Key Considerations For Vitamin D3 + K2 Purchases
- Potency and ratio: Higher D3 doses (5,000–10,000 IU) pair with K2 (MK-7 is generally preferred for longer bioavailability). Choose a ratio that aligns with your healthcare guidance.
- Form and source: Plant-based D3 (VegD3) and MK-7 from fermentation are common in vegan formulas. Coconut oil carriers can improve fat-soluble vitamin absorption.
- K2 form: MK-7 is typically favored for better absorption and a longer half-life than MK-4. Consider MK-7 if you need sustained calcium guidance to bones and arteries.
- Allergen and dietary considerations: Check for non-GMO, soy-free, kosher, gluten-free, or vegan certifications if relevant to your diet.
- Bioavailability: Fat-based carriers and oil solubility improve uptake. Look for softgels or capsules that include a lipid source.
- Immune and mood support: Some formulas emphasize immune health or mood balance in addition to bone support. Align with your health goals.
- Medical context: People with certain conditions or those on anticoagulants should consult a healthcare professional before starting vitamin D and K supplements.
