Can whey protein concetrate cause abdominal pain ?
I tried protein powder for first time and digestion of whey was very hard and long .
After 1 or 2 hour my stomach started to ache .
You can try a few things:
1-mix the protein powder with more water before drinking
2-take enzyme supplements when drinking the protein powder
3-use the protein powder with a regular meal
4-use a better protein supplement, like Low-Carb Grow!
Good luck.
