Solius activates your body's natural vitamin D production through light, unlike pills that depend on digestion and can fail for those with malabsorption challenges. Rather than relying on the liver and kidneys to process supplements, the hormone production begins with UVB exposure on the skin, where vitamin D is meant to be produced. Vitamin D produced through Solius is self-regulating and balanced, helping your body create exactly what it needs. In a published clinical study (Shirvani & Holick, Anticancer Research 2025), Solius produced an average individual increase of 76% (10.2 ng/mL) in serum vitamin D. Vitamin D created naturally through light exposure lasts longer in the body and supports broader biological processes tied to mood, immunity, and metabolic balance. Beyond vitamin D, UVB light also helps activate other light-related biological pathways that supplements cannot reach, supporting whole-body health, vitality, and overall well-being. It’s a more complete and naturally aligned way to support your health from the inside out, and unlike supplements, Solius is FDA-cleared. Many sunlight-associated health benefits do not appear with oral supplementation alone. This suggests that UVB light therapy is more than vitamin D. While vitamin D is the most studied biomarker of sun exposure, it is likely not the primary mechanism of UVB light therapy. Scientific research shows that UVB light therapy activates hormone production, stimulates favorable metabolites, releases nitric oxide, and fosters a diverse microbiome.
