My husband recently ordered Syncolein as recommended by someone on this site for tremors, insomnia and moods from PD. The information given sounded so promising and it says it is a medical food made of natural ingredients from plants that are FDA approved. On the website, the common side effects named were gas/bloating. When he got the actual container, it mentions other possible side effects like diarrhea, chest discomfort, cough, dry heaves, runny nose, shortness of breath, sore throat, tightness in the chest, vomiting, headaches, dizziness, nausea, RENAL FAILURE, urinary retention, arm pain and dehydration.
He would like to get relief from his PD symptoms especially the chronic insomnia, but he is afraid of the serious side effects like renal failure.
Would appreciate hearing from anyone who has been using this product long term. Thank you.
