          1. What do nutrient units mean?

Understanding Nutrient Units

When it comes to nutrition, the amounts of vitamins and minerals we need are incredibly small — much smaller than what we usually measure in grams. That’s why we use different units to describe them:

• Grams (g): Common for powders or larger quantities (a teaspoon is roughly 5g).

• Milligrams (mg): 1,000mg = 1g.

• Micrograms (mcg or µg): 1,000µg = 1mg.

• International Units (IU): Used to measure the biological effect of certain vitamins like D, E, and A (not a weight, but a measure of potency).

Here’s how IU converts for some vitamins:

• Vitamin D: 1 IU = 0.025 µg (D2 or D3)

• Vitamin A: 1 IU = 0.3 µg (retinol)

• Beta-carotene: 1 IU = 0.6 µg

• Vitamin E: 1 IU = 0.67 mg (d-alpha-tocopherol).

  2. What’s the difference between vitamin D2 and D3?
  Both forms need to be activated in the body, but studies show vitamin D3 is more effective than D2. It raises vitamin D levels more efficiently and is stored in your body over 3x longer.*

  3. Where does your vitamin D come from?
  We use high-quality vitamin D3 sourced from lanolin, which is derived from the wool of healthy sheep.

  4. How long does one pack of Bio-Vitamin D3 last?
  It depends on the strength and how many capsules you take each day:

  • 400 IU:
    120 capsules = up to 24 days (if taking 5 daily)

  • 800 IU or 1,000 IU:
    80 capsules = up to 16 days (if taking 5 daily)

  • 5,000 IU:
    40 capsules = 40 days (if taking 1 daily)

  5. Why should people with sarcoidosis check with their doctor before taking vitamin D?
  Vitamin D can raise calcium levels in the blood. If you have sarcoidosis, this may lead to a condition called hypercalcaemia, so it’s important to speak to a healthcare provider before starting a supplement.
