Buying Guide

Choose the right dose for your needs

Vitamin D3 doses in this roundup range from daily 5,000 IU formulations to weekly 50,000 IU options—match dose and frequency to your blood levels and provider recommendations

Look for vitamin K2 when prioritizing bone health

Several options combine D3 with K2 MK‑7 to support calcium utilization for bone health; consider a D3+K2 formula if recommended by your clinician

Pick a convenient dosing format

Formats include gummies, softgels, capsules and weekly high‑dose capsules—choose what you’ll reliably take, whether daily softgels or a weekly high‑dose capsule

Consider delivery oil and bioavailability

Oil-based softgels (for example coconut oil) and MK‑7 forms may improve absorption of fat‑soluble vitamin D3 compared with dry tablets

Match product to dietary preferences

If you follow plant-based diets, select vegan-certified or plant-based softgels and avoid animal-derived ingredients like gelatin
