I have started to use a vitamin and mineral supplement containing antioxidant nutrients and antioxidant herbs after consultation with a naturopath. However I am still feeling a little uneasy about it. I was impressed by the paper titled: Prevention of dopamine-induced cell death by thiol antioxidants: possible implications for treatment of Parkinson's disease. Title Abbreviation: Exp Neural Date of Pub: 1996 Sep Author: Offen D; Ziv I; Sternin H; Melamed E; HochmanA; Issue/Part/Supplement; 1 Volume Pagination; 32-9 Issue: 141 I did note Linda Forrest's Mom's warning re N-Acetyl Cysteine and the failure of NAC to reduce low-density lipoprotein oxidiazability in healthy subjects. To cut a long story short, I have done some research of my own, but it sure is a jungle out there if your not a biochemist. So I will note down the ingredients of one tablet and ask any-one on the list serve who have a better understanding of antioxidants would be kind enough to browse through and tell me if there is any substance in these tablets that would be contra-indicated or suspect. One tablet contains: Quercetin 200mg Bromelain 1200 200mg Ascorbyl Palmitate 87mg d-Alpha Tocopherol Succinate 100iu L-Cysteine 50mg Retinyl Palmitate 5mg (equivalent Vit. A. 2500iu) Silyburn Marianum 36mg (equiv. to 25mg Silymarin) Betacarotene 30mg Zinc amino acid chelate 50mg (equiv. to 5mg elemental zinc) Manganese amino acid chelate 20mg (equiv. to 2mg elemental manganese) Ginko Biloba 10mg Copper amino acid chelate 8.33mg (equiv. to 500mcg elematal copper) Thank you in anticipation.
