12 Best Vitamin D Supplements of 2023, According to Experts



3. Life Extension Bone Restore with Vitamin K2


Bone Restore with Vitamin K2


  • Contains vitamins D3 and K2
  • Magnesium and boron for maintaining healthy bones


  • Four capsules per serving

This complex from Life Extension contains vitamin D3, vitamin K2, calcium, magnesium and boron. Vitamin D3 aids with the absorption of calcium from the digestive tract to the bloodstream while vitamin K2 helps transport calcium from the bloodstream to the bones. Minerals magnesium and boron also work to maintain healthy bones.

Online customer reviews appreciate that the product contains both vitamin D plus vitamins and minerals specifically for bone health, so you can get the best of both worlds in a single supplement (if advised by your doctor, of course). One downside, however, is that the manufacturer recommends four capsules to get a full serving of everything including 1,000 IU of vitamin D.

Directions specify taking two capsules in the morning and two at night, each time with food. Dividing up the dosage makes taking these capsules more manageable, but four capsules per serving increases the cost per serving and can be tough to keep up with.

4. Vitafusion Vitamin D3 Gummy Vitamins


Vitafusion Vitamin D3 Gummy Vitamins for Bone and Immune System Support, Peach, Blackberry and Strawberry Flavored, 50 mcg Vitamin D, 75 Day Supply, 150 Count


  • Affordable
  • No high-fructose corn syrup


  • Two gummies per serving

Gummy vitamins appeal to many, especially those who hate to swallow large pills. These chewy gummies from Vitafusion deliver a sweet balance of natural peach and berry flavors without any high-fructose corn syrup. Two gummies contain 2,000 IU of vitamin D3, so you’ll essentially get 1,000 IU per gummy and can use that to meet your recommended supplementation needs.

These gummies are also highly rated by Amazon reviewers with over 47,000 reviews and an overall 4.8-star rating. One Amazon reviewer said that in addition to being tasty, the supplement never gave them an upset stomach like they used to get with supplements in pill form. Just remember that gummy vitamins are not candy, and eating too many can lead to serious side effects and health problems related to vitamin toxicity, so it’s always good to make sure you keep them away from children.
