Milk allergy is different from lactose intolerance

Whey is milk protein. A lactose-free label does not make a milk-protein product suitable for milk allergy; reactions can be severe. 1

Lactose intolerance concerns milk sugar instead. Concentrate can be problematic, while isolate generally contains less lactose; the individual product still matters. 2

Does more always mean better?

The US Food and Nutrition Board has not established a protein upper limit. NIH nevertheless notes limited evidence on adverse effects of very high intakes; an athlete’s intake range is not an unlimited safety guarantee. 3

Kidney disease changes the question

DGE warns that higher protein intake can worsen existing impaired kidney function. General sports targets therefore cannot be applied to that situation without individual assessment. 4

For information, not individual medical advice. Ingredient studies do not establish the effectiveness of these products.
