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

Common complaints: - Some users report gas (5-10% of reviews) - Usually from drinking too fast - Mix with more liquid helps

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)
