If you are taking any other supplments, check those and their manganese content before starting on blackstrap molasses. It may save you quite a bit in the way of anxiety and medical bills.
Be careful about Manganese -- it can cause symptoms of Parkinsons' Disease or Bells Palsy. 'I was taking a number of supplements that included manganese. The muscles on the right side of my face started to go slack and I was unable to use my mouth effectively. I thought I was having a stroke. Luckily I had a friend over who took me to the emergency room. I was diagnosed with Bells Palsy. It was supposed to go away within 1-2 months. It persisted for "7" months. I ran across something on the interment stating that overdosing on manganese can cause Parkinson's type symptoms. After checking the supplements I was taking I found that I was taking roughly 600 to 800 times the daily recommended allowance of this mineral. After I threw out these supplements my Bells started to clear up. If you have any similar type symptoms check what you're taking and eliminate those with manganese.
