 So remember, when you combine my H and B with vitamin D and creatine, it's the triple whammy of fighting muscle loss if it's related to the diet or related to lack of exercise. And remember, this combination also works, you're going to love this, for people that don't even exercise. You hear that, Mark? You can take a combination of creatine, vitamin D, and my H and B without even exercising and it increases muscle synthesis and strength.
