My girlfriend was trying to look up some info on vitamin and herbal remedies for Mood balancing and stress relief, as well as helping with quality of sleep. She is looking to stay mainly in the Vitamin/Herbal remedies any help or suggestions would be appreciated. She is 21, 5'3 and 135lbs. works out around 3 times a week.
There are several options that might interest her. Can you be a bit more specific about the problem(s)?
In the meantime, here are a few compounds you might look into:
GABA (amino acid, good for anxiety, increases alpha brain wave production - great for relaxation)
Kava kava (herb, helps some people with anxiety-type symptoms - I've heard tinctures work best)
L-Theanine (amino acid, has a calming effect, possibly a slight mood lift)
5-HTP (amino acid, used as a mood enhancer, has a relaxing effect on some people)
If you're looking for a good herbal blend for general stress then I highly recommend "Stress Advantage" by New Chapter (it combines a select group of adaptogenic herbs). I would also suggest a good multi to make sure she's not deficient in something.
Cheers! (literally)
