Vitamin D supports the immune system and helps prevent issues with autoimmunity. Studies indicate that vitamin D can help improve the innate and adaptive immune responses and help the body maintain homeostasis (1).
Studies show that Vitamin D has been shown to reduce inflammation and possibly prevent the development of chronic inflammatory disease (2). There is substantial evidence that vitamin D specifically helps reduce inflammatory cytokines and reduce inflammation involved in cancer and tumor development (3).
Vitamin D helps support the gut most directly by improving and enhancing the gut microbiome. Vitamin D is thought to improve intestinal barrier function, benefit the microbiome composition, and meditate the gut-immune responses (10). These benefits may help prevent both digestive disorders and autoimmune diseases.
Studies show that vitamin D supplementation reduced BMI in overweight and obese women after six weeks, and may be helpful for reaching weight loss goals (11).
Vitamin D may protect the heart. Deficiency of vitamin D is linked to cardiovascular disease, while studies also suggest that vitamin D helps prevent hypertension and cardiac arrest by down regulating the renin-angiotensin-aldosterone system and improving glycemic control (7).
Vitamin D also supports the heart and liver by managing blood sugar levels and reversing insulin resistance (8). Studies show an improvement in HbA1c levels after using supplementation to reach adequate vitamin D levels (9).
Low levels of vitamin D are correlated with increased fatigue and poor energy. Supplementing with vitamin D has been shown to improve fatigue (12).
Clinical studies show an inverse relationship in serum vitamin D levels and the risk of developing allergic conditions like allergic rhinitis (4).
