Tag: Vitamin d3 vs d2

According to the National Institutes of Health, almost one out of four Americans has blood levels of vitamin D that are too low for bone and overall health, highlighting the need for alternative sources. Many people rely on sunlight, but factors like climate, skin tone, and sun-protective clothing mean that other methods are necessary to answer the question, "Can you get vitamin D from anywhere else?"

While the efficiency varies considerably among individuals, studies suggest that vitamin D absorption from supplements in healthy people can range from 55% to 99%. The amount of a vitamin D supplement that is actually absorbed is influenced by a number of factors, including the supplement's formulation, dietary habits, and individual health status.

According to a 2014 study of 50 older adults, consuming vitamin D alongside a high-fat meal increased blood levels by 32% compared to a fat-free meal. To understand what's the most effective way to take vitamin D, it's crucial to look beyond just the dosage and consider factors like meal timing, companion nutrients, and supplement type to maximize absorption.

According to national surveys, vitamin D deficiency is a surprisingly common condition, affecting millions of people worldwide. The best treatment for vitamin D deficiency is often a combination of supervised oral supplementation, dietary adjustments, and safe sun exposure to restore healthy levels and prevent complications.
