Vitamin D3Updated 2 days ago

Why does Vitals⁺ include Vitamin D3?

Vitamin D3 is crucial for strong bones and muscles, immune health, and calcium absorption—yet it’s one of the most common global deficiencies, particularly in winter months and among those following vegan diets.

Vitals⁺ includes 45μg of Vitamin D3 (that’s 900% of your NRV) in a high-quality, vegan form of cholecalciferol derived from lichen. This dose is purposefully chosen to reflect modern research around optimal—not just minimum—levels for wellbeing.

🤔 What does Vitamin D3 actually do?

Vitamin D3 (cholecalciferol) plays a vital role in:

• Maintaining healthy bones, muscles and teeth by regulating calcium and phosphate

• Supporting the immune system, especially during times of low sun exposure

• Helping with muscle function—linked to physical strength and balance

• Improving calcium absorption, ensuring you get more from your diet and supplements

It also indirectly supports mood, energy levels, and long-term heart and brain health by contributing to calcium balance in tissues.

🤔 Why D3—and why this dose?

We use cholecalciferol (D3) because it’s the most effective form: twice as efficient at raising blood levels of vitamin D compared to D2.

The 45μg dose (1800 IU) is well within the EFSA’s updated safe upper limit of 100μg/day for adults and teens. It’s designed to ensure you reach—and maintain—optimal blood levels, even in months with limited sunlight.

🌱 Why vegan?

Most D3 comes from lanolin (sheep’s wool), but we use a vegan lichen-derived source that’s suitable for all diets. It’s the same highly bioavailable form as standard D3—just sustainably sourced and 100% plant-based.

The EFSA’s 2023 safety review confirms that up to 100μg/day of vitamin D3 is well-tolerated across all adult age groups.
