Someone recommended Well Man tablets last year when I had terrible trouble sleeping (such as Im having thesedays again). I keep fit. I eat healthy I dont drink alcohol, I drink only 3-4 cups or tea a day (weekends otherwise 1-2 weekdays), the odd cup of coffee.
I'd be interested to know if they help 'pick you up'.....for sure.
TBH any sportsperson needs more than the RDA of Vits etc etc so taking on additional supplements might not be very noticeable physically but Im sure there are subtle benefits unnoticed within your body.
