Brought my moody teenager back!!!

Posted by 5386981317895263463 on Dec 13, 2016

My 14 year old daughter has been having issues with feelings of sadness, and lack of joy since she started her period. The feelings began to not only be once a month, but started to last longer stretches of time. I spent quite a bit of time researching supplements for her (I also work in functional medicine so I have a doctor to ask advice) as I DO NOT want a mental health diagnosis on her record, and I don't want her to struggle either. I think she just needed a bit of support with all the changes going on in her body, and she's a teenager, and doesn't eat as well as I would like! I found this combo to work REALLY fantastically: TMG, 5-HTP (Now Foods), & L-Tyrosine (Now Foods) and she is smiling, she is not locked in her room all the time, she is out and engaged in the family and I feel like I've gotten my baby back! She really did need some support. I do also have her on a whole food vitamin from Standard Process, a good probiotic from Xymogen, and she takes Maca (now foods) to help with her cycles.

the tablets are no longer coated and now become puffy and crumble when exposed to air. Too bad because I loved this brand. This happens when I put them in my weekly pill organiser even when I use one of the little packets of moisture remover

great for methylation

Posted by kanaca on Mar 02, 2014

I'm testing to see if my body will make SAM-e from this and Methionine. What I can tell in two weeks is that it's boosted methylation. In a week or so, I intend to cycle off SAM-e and see for sure. Then will update my review. So far, it feels like I've eaten powerful greens after taking a dose.
