Product Description
Indoor training, winter months, and high-latitude living all reduce the sun exposure your body needs to produce vitamin D on its own, and low vitamin D status has been linked to increased stress fracture risk and immune dysfunction in athletes specifically. Most people don't find out they're low until a blood test tells them.
Pure Encapsulations Vitamin D3 supports bone density, immune function, and cardiovascular health, with dosing options to match your specific needs.
Supports Bone Density – Vitamin D governs how well your body absorbs and retains calcium, directly relevant to the bone density athletes need to withstand repetitive impact training.
Backs Up Immune Function During Heavy Training – Vitamin D receptors sit on immune cells throughout the body, and low vitamin D status has been linked to immune dysfunction, relevant during the higher-volume periods when illness risk already climbs.
Available Across a Range of Strengths – Pure Encapsulations offers this in 400 IU up to 10,000 IU capsules and a liquid option, so dosing can match anything from general daily maintenance to addressing a confirmed deficiency under practitioner guidance.
Vitamin D promotes intestinal calcium and phosphorus absorption and reduces urinary calcium loss, both essential for maintaining healthy bone composition, an established concern for athletes with high training volumes and stress fracture risk. Vitamin D receptors are found on immune cells including lymphocytes and macrophages, supporting healthy immune cell activation, and vitamin D also supports cardiovascular function and cellular health, including support for breast, prostate, and colon tissue, in some individuals.
How to Use Pure Encapsulations Vitamin D3
Dose: Suggested use varies by strength — follow the directions on your specific product, or as directed by a health professional. Take with food.
