Some readers have asked about whether it’s safe to use L-Glutamine with children, based on an article that appeared on Dr. Joseph Mercola’s website. But again, read through it carefully and you’ll see that this is only an issue when intake exceeds need. Otherwise, there is no excess and the body utilizes it fully.
Also, in this article he completely warns against any L-Glutamine intake by pregnant women as it can cause retardation. However, I drank 1-2 Absorb Plus shakes per day (containing 1000 mg L-Glutamine in each shake) during both my pregnancies and breastfeeding. Both my children’s teachers are amazed at their quickness and intelligence and they consistently outperform many of their peers in both physical and mental function.
And one of my readers used The IBD Remission Diet for seven weeks during her pregnancy (to avoid having to use Prednisone), which meant she was drinking 4-5 Absorb Plus shakes per day (4,000 – 5,000 mg L-Glutamine per day) and her baby was perfectly healthy with normal brain development. The last time I heard from her, the baby was three years old and doing very well in all aspects.
Remember too that this article is just one professional’s opinion – and while it is worth reading, the majority of professional opinion and clinical trials in children show no adverse effect for appropriate L-Glutamine supplementation.
Here’s the result of my research and my personal opinion on the topic:
Kids with sickle cell anemia need higher amounts of L-glutamine. So this study assessed response/effects with a massive dosage of 600 mg of L-Glutamine per 1 kg of body weight. Which means, for example, that a child weighing 44 pounds would ingest 12,000 mg of L-Glutamine per day. Even at that very high dose, this study (below) on children as young as 5 years old showed no negative effects of supplementation.
