Does Sunscreen Affect Your Vitamin D Levels?

Many people worry that daily sunscreen use might cause vitamin D deficiency. This resource explains that sunscreen does not completely block UV rays, and even with regular use, enough light penetrates the skin to allow vitamin D production. Research shows sunscreen does not lead to deficiency in real-world conditions, and most people get sufficient vitamin D from everyday sun exposure, diet, or supplements. The benefits of sunscreen in preventing skin cancer, sunburn, and premature aging far outweigh any risks. For those still concerned, vitamin D levels can be checked and supported safely with food or supplements.
