Let me introduce myself. I'm 62 years old and have had Parkinson's symptoms for about two years. However, I've only known what it is for about 7 months, when I finally went to a urologist. I was taking Sinuate and Eldepryl which helped my symptoms and enabled me to write again and walk better and eat better. The whole right side of my body was becoming rigid. The drugs caused me to have insomnia and other side effects. Approximately two months ago I gradually switched from Sinemet and Eldepryl to NADH, brand named Enada produced by Kal company. It has relieved my symptoms as well as the Sinemet without any side effects. I am sleeping like a baby. I buy it from the health food store in boxes of 30 tablets 5 mg each. I read on the net that Dr. Birkmeyer who discovered both L-dopa and NADH recommends 20 to 25 mgs a day for people with PD. This is about $50 a week. I recently read that fava beans produce dopamine in the body, so I was surfing the net for fava beans and found your page. By the way, there is a lot about fava beans on there and it confirms that they are effective and do pass the brain blood barrier. One and 3/4 oz of the beans equates to 70% of one Sinemet CR and lasts 5 hours. Looking forward to interacting with other PD people. Carol Phelps [log in to unmask]
