FAQs
Does glutamine improve performance?
Evidence is weak. The NIH Office of Dietary Supplements says research to date does not support taking glutamine alone to improve exercise and athletic performance. Some people still use it as part of a training routine, but it is not a substitute for enough total protein.
How many serves are in each tub?
The 75 serve tub gives 75 scoops of 5 g L-glutamine and the 130 serve tub gives 130 scoops. At one scoop a day, that is about two and a half months or just over four months of use.
Can I mix it into my protein shake?
Yes. It is unflavoured with nothing else added, so Rule 1 suggests stirring it into a protein shake, workout drink or juice. The fine powder is micronised to help it mix and stay suspended.
When should I take it?
Rule 1 suggests taking it during or after workouts, mixed into a cold drink or protein shake. Because it has no stimulants or flavour, it can be added to whatever you already drink around training without changing the taste much.
