Question 236 of 433
Has any supplement been proven to extend human life?

The short answer
No. Not one.
A few correct deficiencies. A few improve specific things, such as muscle strength or triglycerides. Several move aging “markers” slightly in the right direction. None has been shown in a human trial to make healthy people live longer. A claim of longer life needs a trial measuring longer life.
