Whey ProteinProtein Source
Common dairy-derived protein that sometimes appears in the other ingredients list due to label parsing
How to Take It
Best taken in the evening
Take at night. Other amino acids compete for brain uptake, so a protein-heavy meal blunts it. Take it between meals, away from food.
On an empty stomach
Keep it away from protein-heavy meals
Space it a couple of hours from SAMe
