While some supplements can be helpful, you need to see if your body is lacking in them to avoid over loading your system.
I am a believer of good nutrition, promoting good health, mentally and physical.
But caution should be taken, some health foods stores try to push many of their products on the public, which some people will take an abundance of vitamins,herbals, and supplements, possibly doing more harm than good.
I know a few people that have gone to nutritionists and had counseling where they designed a "custom" type regimen which really helped them.
I'm wishing you luck with your questions on these supplements. Also, feel free to come here and share with us what you were able to find out about these supplements.
Take care now,
