I have been taking 300mg daily for at least three years. One in morning and one at night. Since I am on social security some times I cannot afford to purchase it. During those times neuropathy in my feet (especially) gets much more painful. I have been out of it for two months and know the difference. However, I had not been told to take it at meal time. I did drop the recommended dose down to the 300 mg instead of 450 mg reccommended because it is oil based and I was hoping for no complications. Great stuff!!!
