Let you hang around. In fact, this is a sales tool. Sell more products and earn more.
I have done this work and know it very well.
But protein powder is really a good nutritional supplement, and it is also used by white-collar workers to lose weight.
The effect still needs to be taken for a long time to have an effect.
Personally, I think the B family is very scarce for office workers, but the purpose is not to lose weight better, but to recuperate the body.
My opinion is that if you are healthy, there is no need to take B family to help protein lose weight.
Hope helped you.
