The hidden cost of trying to get all your vitamin D from pills

Free product guide - https://canva.link/vqycebyg1ulkohf Sarah, a certified nutritionist and applied quantum biology practitioner, reviews a 2025 study in vitamin D–deficient post-menopausal women with early bone loss comparing vitamin D3 supplements alone versus supplements plus UVB lamp exposure three times weekly. Both groups started around 16 ng/mL; after six months the pill-only group rose to ~20 ng/mL while the UVB-plus-pill group rose to ~27 ng/mL. The pill-only group showed virtually no change in knee/muscle strength and no meaningful bone density improvement, while the UVB group improved strength and increased bone density at the spine and hip. She suggests UVB benefits may extend beyond vitamin D because sunlight creates a “solar metabolome” (e.g., lumisterol, tachysterol) and discusses additional sunlight effects from separate research, including UVA-driven nitric oxide release affecting blood pressure, red/infrared mitochondrial effects via cytochrome c oxidase, and UVB-triggered beta-endorphin and alpha-MSH.
