I feel that your boyfriend really cares about his health, and it is also a good thing to continue fitness. Besides, a few hundred dollars a month for fitness is not expensive, and it should be within your tolerance.

However, there is no need to take sports supplements to make up for this and that. The normal physiological mechanism and physiological regulation of human body can completely ensure good health, as long as you eat reasonably and don't overeat. There is absolutely no need to take all kinds of supplements.

I feel that it's not a bad thing to just keep fit. My colleague basically keeps exercising for an hour every day, but never takes any supplements.

Eating more supplements has a negative effect on your body's regulatory mechanism.
