Can vitamins really boost your immune system, or is it all expensive hope? We looked at what the big studies actually found, and the answer is not what the supplement aisle wants you to believe.
You’ll see what a huge Cochrane review found about vitamin C and colds, why a major 2017 analysis of vitamin D trials points to a surprising twist for people who start out deficient, and why zinc is a short-term gamble rather than a daily habit. We also break down the daily amounts that matter and the upper limits worth respecting. This video is educational and not medical advice, so talk to a doctor or pharmacist before starting or changing any supplement.
