Vitamin D — the “sunshine vitamin” — does more than just support your bones. It acts like a hormone in your body, vital for immune strength, muscle performance, mood balance, and long-term health. Yet, studies show around half of the world’s population doesn’t get enough.
Why Vitamin D Matters
-
Powers your immune system to fight infections
-
Supports strong bones and muscle recovery
-
Helps regulate mood and energy levels
-
May reduce risk of some autoimmune conditions
Backed by Science
-
A 2017 BMJ meta-analysis of 25 trials involving 11,000+ people found vitamin D supplementation reduced risk of respiratory infections, especially in those who were deficient.
-
The 2022 VITAL Trial published in BMJ tracked 25,871 participants over ~5 years and showed that 2000 IU of vitamin D daily lowered autoimmune disease risk by 22%.
Where Vitamin D Comes From
-
Sunlight (UVB rays): Your body’s primary source, but many of us don’t get enough due to indoor lifestyles, sunscreen, seasons, and pollution.
-
Food: Fatty fish, eggs, and fortified products help — but rarely meet daily needs.
How Much Do You Need?
Recent trials, including VITAL, suggest 2000 IU daily for optimal health. Here's how to reach it:
-
Sun exposure: 15–30 minutes of midday sun, a few times per week
-
Supplementation: ProGood Immunity Plus delivers 1000 IU Vitamin D3 per scoop — so 1–2 scoops daily hits that 2000 IU mark and also supports your immune system with Vitamin C, Zinc, Elderberry, and Echinacea.
