请教：DMG会导致孩子亢奋吗？

crescent666

买了液体的瓶装DMG,刚给儿子吃了一个礼拜，觉得他比以前容易亢奋，脾气暴躁点，然后晚上睡觉需要的时间也更多了。大家遇到过类似状况吗？

另，DMG是只对自闭有效果，还是语言不好的发育迟缓儿吃也会有效果呢？

没有足够证据表明对自闭或语言迟缓发育迟缓有效。

给楼上加个参考文献（from wiki)：

Dimethylglycine (DMG) is a derivative of the amino acid glycine with the structural formula (CH3)2NCH2COOH. It can be found in beans and liver. It can be formed from trimethylglycine upon the loss of one of its methyl groups. It is also a byproduct of the metabolism of choline.

When DMG was first discovered, it was referred to as vitamin B16, but, unlike true B vitamins, deficiency of DMG in the diet does not lead to any ill-effects meaning it does not meet the definition of a vitamin. In legal terms, it has been deemed a food product and, as such, is available without a practitioner or prescription.

Uses

Dimethylglycine has been suggested for use as an athletic performance enhancer, immunostimulant, and a treatment for autism, epilepsy, or mitochondrial disease.[2][3] Published studies on the subject have shown little to no difference between DMG treatment and placebo in autism spectrum disorders.[4][5]

翻译一下关键句：

DMG被认为可以用于自闭症和癫痫的治疗，但相关研究表明，在自闭谱系障碍方面，DMG和安慰剂相比并无区别，或者说区别甚微。

简单说：没有足够证据表明有用。
