    About Vitamin D

    Vitamin D supports calcium absorption, bone and teeth health, muscle function and normal immune function. Your skin makes vitamin D from sunlight, but season, latitude, sunscreen and time spent indoors mean many people get less than they need, especially during winter.

    Vitamin D supplements come in several strengths and formats. Here is how to compare them.

    How to Choose a Vitamin D Supplement

    • Vitamin D3 vs D2: Vitamin D3 (cholecalciferol) is the form your skin makes and the form used in most practitioner supplements. Vegan D3 made from lichen is also available.
    • D3 with K2: Vitamin K2 helps direct calcium into bones, so many people prefer a combined product. See our vitamin K collection.
    • Strength: Products range from 1,000 IU to 10,000 IU per serving. Higher strengths are generally intended for use under a practitioner's guidance.
    • Format: Softgels and capsules are convenient, while liquid drops and emulsions make it easy to adjust the dose and work well for children.

    Vitamin D works hand in hand with calcium and magnesium, which your body needs to activate vitamin D. Explore bone health and immune support for complementary products.

    Frequently Asked Questions

    Should I take vitamin D3 or D2?

    Most people choose vitamin D3. D3 is the same form your body makes from sunlight, and it is the form found in most of the products we carry. Lichen-based D3 is an option for those who avoid animal sources.

    How much vitamin D should I take?

    The RDA is 600 IU per day for most adults and 800 IU for adults over 70. The National Institutes of Health sets the adult upper limit at 4,000 IU per day unless a practitioner recommends more. Many practitioners test 25-hydroxy vitamin D levels to personalize the dose, which is why higher-strength products are available.

    Why is vitamin D often combined with K2?

    Vitamin K2 helps direct calcium to bones and teeth. Because vitamin D increases calcium absorption, many practitioners pair it with K2. If you take a blood-thinning medication, talk to your practitioner before adding vitamin K.

    When is the best time to take vitamin D?

    Take it with a meal that contains some fat. Vitamin D is fat soluble, so it absorbs better alongside food. Many people take it with breakfast or lunch to make it part of their routine.

    Is liquid vitamin D better than capsules?

    Both work well. Liquids are easy to dose for kids or for adjusting your intake, while softgels and capsules are convenient for travel. Choose the format you will take consistently.
