## Questions & Answers

**Q: Can I take vitamin D3 and iodine together?**
A: Yes! Because many people struggle to get enough of these two essential nutrients to support bone, brain and thyroid health, we’ve combined them into a single, convenient vitamin D and iodine supplement.

**Q: What should you avoid when taking vitamin D3?**
A: Avoid uncontrolled supplementation. Your skin manufactures vitamin D when exposed to sunlight, and this supplement delivers 5,000 IU of vitamin D3 daily, so take a 25-hydroxy vitamin D blood test after three months to assess and adjust your dosage.

**Q: What is vitamin D3 best absorbed with?**
A: Vitamin D is a fat-soluble vitamin, so it is absorbed best by the body when it is taken with fats. This means you should take your vitamin D supplement with foods prepared with healthy fats for optimal results.

**Q: Is it best to take vitamin D3 in the morning or at night?**
A: Your vitamin D supplement is best taken with food, so whether you take your vitamin D in the morning or at night depends on your eating habits. If you skip breakfast, take vitamin D3 with your evening meal.

**Q: How to take vitamin D3?**
A: Healthy fats are the best way to get vitamin D3 absorbed by your body for the best health benefits. Take your vitamin D3 with healthy fats like avocados, nuts, seeds, eggs and whole milk dairy products.

First time trying this brand, but with thyroid issues, I was thrilled to find a D3 option with iodine! Very easy to swallow, flavorless and a great price point! Efficacy equally pleasing.
