Buying Guide: D3 + K2 For Weight and Wellness
- What to look for in D3 + K2 supplements: D3 dose (IU), K2 form (MK-7 is common and highly bioavailable), carrier oil (coconut/MCT improves fat-soluble vitamin absorption), and any extras such as magnesium or zinc.
- Choosing the right dose: Lower-dose options (5000 IU D3) suit daily maintenance; higher-dose formulas (10,000 IU D3) may support those with limited sun exposure but should be used under guidance if required by health conditions.
- Plant-based vs. non-plant-based: Vegan D3 sources are available; MK-7 is commonly sourced from MK-7 in chickpeas or fermentation. Decide based on dietary preferences.
- Allergen and ingredient considerations: Check for gluten-free, non-GMO, soy-free, or other allergens relevant to your diet.
- Delivery form and portability: Softgels vs. capsules, and packaging size may influence daily use and storage.
