Hi. I don't know how much she was taking, I know she was using a product called Intestinew though, which contained those two supplements. I think its similar to what you were taking because you can buy it in a powdered form. I also think she tried alot of other things before she tried L-glutamine and glucosamine. If you go back a page a two on this forum you will see all of her messages. Another person on this forum has started taking these supplements as well, and has noticed some improvement. I actually think that I have candida/leaky gut and this is what is causing the odour. I have been trying to find out about side effects of taking L-glutamine, as I have heard that there is some. Some people who have took this who have 'leaky gut' experience shakes, as it goes directly into their bloodstream. I think its worth trying though. People on these forums who have noticed improvements with their body odour keep mentioning these two supplements, so they must help.
