Common Questions

Before You Take It

How Do I Take It?

Take one capsule daily with food, following your current bottle directions.

Is This An Everyday Dose For Everyone?

5,000 IU is a high-potency dose, above the general adult daily upper limit of 4,000 IU. Use an individualized plan informed by your vitamin D status, and account for vitamin D in other supplements.

Can I Take It With Heart 1 Or D3 + K2?

Both already supply 5,000 IU D3 per full serving. Account for that overlap before adding another D3 product.

What Is The Difference From D3 + K2?

This is the standalone D3 formula. D3 + K2 also provides 180 mcg MenaQ7 MK-7.

How Long Does One Bottle Last?

120 one-capsule servings. Actual use should follow the individualized dose appropriate for you.
