Vitarx Vitamin D3 Overview: How Does This Supplement Help Your Immune Health and Overall Wellbeing?

Did you know nearly 20% of Americans hover in the danger zone of inadequate vitamin D levels, despite plentiful sunlight and fortified foods?

If you're banking on daily sun exposure alone, you're missing the hidden factors—like skin tone, age, and geographic location—that can greatly impact your body's natural production of the very important vitamin D3.

Add dietary limitations or the inability to consistently eat vitamin D-rich foods, and it's easy to see why supplements become a useful ally.

VitaRx Vitamin D3, formulated to support vitamin D absorption and contribute to bone health, immune function, and overall well-being, can help fill nutritional gaps.

Understanding vitamin D

Vitamin D is an essential nutrient best known for supporting bone health, and emerging research suggests it may also influence immune function, mood and more. Known as the "sunshine vitamin," vitamin D is made by the body in response to sunlight, though it can also be gotten from foods and supplements.

Vitamin D comes in two main forms: D2 and D3. While both are helpful, vitamin D3 is the preferred form for supplementation because it raises blood levels of 25-hydroxyvitamin D—the standard measure of vitamin D status—more effectively than D2.

Here’s a side-by-side comparison:

Vitamin D obtained from sun exposure, diet, or supplements is biologically inactive and must be changed by the liver and kidneys to its active form. Without enough vitamin D, bones can become thin, brittle, or misshapen, and risks of diseases like osteomalacia in adults or rickets in children go up.

But wait—does all sunlight exposure give the same amount of vitamin D? Actually, time of day, skin tone, age, and geographic location, and even sunscreen use all greatly affect how well your body makes vitamin D from sunlight.

Despite its importance, vitamin D deficiency is still common in the United States, with nearly 20% of the population at risk for inadequacy and 5% at risk for deficiency. (This shows why choosing a dependable vitamin D3 supplement, like VitaRx, is so important for many people)

Recommended daily intake

The recommended daily intake of vitamin D varies by age and situation. For most adults up to 70 years old, the recommended amount is 600 IU (15 mcg), and 800 IU (20 mcg) for those over 70. Pregnant or lactating women should aim for 600 IU (15 mcg). For infants and children, 400–600 IU is usually enough.

But what if your blood test shows low vitamin D even when following these guidelines? Your doctor may suggest temporarily higher doses.
