L-glutamine capsule review

Very easy to get down and no stomach troubles like there can be with certain supplement capsules, major decrease in DOMS even after hitting legs so it's easier to go as hard as I can every day. Other than that not too much of a difference but it's noticeable despite having only been taking it for about a month

Better gut

I use this to help with the symptoms of IBS. I take it when I have bloating, gas and constipation. I use it for 4 or 5 weeks at 4500 mg a day and my symptoms clear up for 8 or 9 months. I take it under a doctor's advice.

Muscle Recovery

I've been using this product both before and after working out for several years now and it definitely seems to help with muscle recovery after strenuous exercise. <br />Would definitely recommend giving it a try if your muscles seem to take a long time to recover after exercise!

Good Supplement

I take this with my morning and afternoon multivitamin (GNC Mega Men) and it seems to give me a slight energy boost. I also like that it may benefit GI and liver health.

Good Product I recommend it.

I work out twice a day morning is weights and run afternoon is boxing classes. I’m real sore doing 2 a day burning up to 1,600 calories. I take these after my workout before dinner to help with my sore muscles. I don’t feel as sore the next day.

Jonathan RVerified Buyer

Absolutely love the recovery effect from this.

COURTNEY HVerified Buyer

Better more consistent customer support please.

I imagine it would be good if I ever did get it. But since contacting support gives you different answers by the day, I guess I won't know. In the meantime , I will prepare to contact my credit card about my missing order.

Glutamine expedites muscle repair!

I'm an older adult attempting to gain muscle size through heavy weight training. GNC L-Glutamine is crucial in the immediate repair of all muscles stressed during intense weight lifting.

Mark RVerified Buyer

Been using L-glutamine for 8 months now. I run 6 days a week and it has definitely helped with muscle repair and soreness. As well as boots my workouts. I take 2 before my workout and 2 after and it has definitely been a game changer to be able to wotk out every day and stay on shape.

L-Glutamine

Higher dosage in one tablet.

Michael CVerified Buyer

Off label use of L-glutamine reduces diarrhea.

It helps to extend my chronic diarrhea cycle from three or four days to six or seven days so far. I take about 4.5 g per day, sometimes less.
