Vitamin D3 – Support for Bones, Muscles and Immune System

Our Vitamin D3 capsules contain 55 µg (2200 IU) cholecalciferol per capsule, providing 1100% of the daily reference intake. Vitamin D3 helps maintain strong bones and teeth, supports muscle function, and contributes to normal immune system function.

Why choose Vitamin D3 from POWDR.?

  • Calcium and phosphorus absorption*: supports bone and tooth mineralization
  • Strong bones and teeth*: helps maintain a healthy skeleton
  • Muscle function*: contributes to normal muscle performance
  • Immune system*: supports the body's defense mechanisms
  • High dosage: 55 µg (2200 IU) vitamin D3 per capsule, ideal with limited sun exposure

What's in our Vitamin D3 capsules?

Each capsule contains Vitamin D3 in the form of cholecalciferol, the same form your body produces under sunlight. This fat-soluble vitamin is often better absorbed when taken with a meal containing fat.

  • Supports absorption and utilization of calcium and phosphorus
  • Contributes to the maintenance of normal bones and teeth
  • Helps the immune system function normally
  • Supports normal muscle function
  • Plays a role in the cell division process

Who is Vitamin D3 suitable for?

Vitamin D3 is important for everyone, but extra attention may be needed for:

  • People with limited sun exposure (winter months, indoor work)
  • Elderly, whose natural production in the skin decreases
  • People with darker skin tones
  • Athletes and active individuals who want extra support for bones and muscles

Our high dosage of 55 µg per capsule helps maintain optimal vitamin D levels, especially during periods of limited sun exposure.

Vitamin D3 vs D2, and combination with K2

Vitamin D3 (cholecalciferol) is the same form produced naturally in the skin. This form is better utilized than Vitamin D2 (ergocalciferol), which is mainly found in plant sources.

Combined with Vitamin K2, D3 can further help transport calcium to the bones and prevent its buildup in blood vessels.
