Vitamin pills put to the test: do they really boost skin and energy?

This study looks at whether taking vitamin and mineral supplements for 12 weeks can improve skin health and how healthy people feel overall. About 120 healthy Chinese adults with low fruit and vegetable intake will take either the supplements or a placebo. Researchers will measure skin changes with special cameras and probes, and ask participants about their energy, mood, and digestion. The goal is to learn more about how nutrients affect skin and well-being, not to prove any medical claims.
