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.

A beautiful vegan product that works quickly

Posted by 5069493488113249759 on Dec 02, 2016

I have never been diagnosed with depression, but I have suffered from some acute episodes of depressed feelings, so my naturopath recommended that I take this. Along with myriad other lifestyle improvements (creating a community, being active and busy, meditating), 5-HTP boosts my feelings of happiness, self-worth, and satisfaction. I have, on two or three occasions, forgotten to take the pill before bed and I noticed myself, truly, feeling a bit sad the next day. It may be a coincidence, but 5-HTP really helps me. Thank you, NOW!
