Vitamin D is essential for bone strength, immune function, and overall health. While sunlight is the best source, many of us don’t get enough—especially in the winter. That’s where supplements come in.
I tested a variety of vitamin D supplements in different forms: capsules, gummies, liquids, sprays, and chewables. Whether you’re looking for a vegan option, a budget-friendly pick, or a high-dose formula, I’ve got you covered. Below are my top picks, plus everything you need to know before choosing a supplement.

How Much Vitamin D Should You Take?
Most adults need 600–800 IU of vitamin D daily, but many experts recommend 1000–2000 IU for optimal health. If you have a deficiency, your doctor may suggest higher doses. The safe upper limit is 4000 IU per day unless directed otherwise by a healthcare provider.
What Form of Vitamin D is Best?
- Capsules & Softgels: Easy to swallow and widely available.
- Gummies: A good option for those who dislike swallowing pills.
- Liquids & Sprays: Ideal for those who need flexible dosing or quick absorption.
- Vitamin D2 vs. D3: D3 (cholecalciferol) is more effective than D2 (ergocalciferol) at raising blood levels.
Final Thoughts
Whether you prefer a capsule, gummy, or liquid, there’s a vitamin D supplement that fits your needs. If you want an affordable, no-fuss option, NatureWise Vitamin D3 is a great choice. If you prefer a liquid, Carlson Labs Vitamin D3 Drops offer flexibility. And for those who want extra K2 for bone health, Sports Research D3+K2 is worth considering.
Make sure to choose a high-quality supplement from a trusted brand and take it consistently to maintain optimal vitamin D levels year-round.
