Buying Guide

Choose the right IU for your needs

Match supplement strength to your blood level goals and medical advice, from daily 5,000–10,000 IU options to weekly high-dose formulations

Look for vitamin K2 pairing

Products that include K2 (especially MK-7) help direct calcium to bone and are commonly recommended for bone-support regimens

Pick a bioavailable delivery form

Softgels and oil-based formulations can improve absorption of fat‑soluble vitamin D3 compared with dry tablets

Consider dosing frequency

Weekly high-dose capsules offer convenience while daily softgels or gummies support routine dosing and adherence

Check for dietary preferences

Select plant-based or vegan-certified formulas if you avoid animal-derived ingredients, or choose gummies if you prefer chewables
