Digestion & Side Effects
Digestibility: 8/10
My experience: - No bloating - No gas - No stomach discomfort - Easy to digest within 30 minutes
Lactose sensitivity: - Contains lactose (from whey) - If lactose intolerant: Consider Gold Standard Isolate (99% lactose-free) - Or take lactase enzyme

Artificial Sweeteners
Contains: - Sucralose (Splenda) - Acesulfame potassium
My take: - No side effects noticed - Approved by FDA - Keeps calories/carbs low
If you avoid artificial sweeteners: - Try Optimum Nutrition Natural Whey - Or Legion Whey+ (naturally sweetened)
