Thank you for your query at DoctorSpring.com
According to the pdf, each amount per serving (1g) contains nutrients which are within RDA (recommended dietary allowance) for each day. For example the RDA for folic acid is 400mcg/day, the amount of folic acid in 1 serving of the product is 0.6mcg. Therefore I would recommend limiting your intake to 1 tablet a day to prevent vitamin toxicity.
Additionally, of note, is that the benefits mentioned such as ‘provides 20 natural amino acids which enhance brain activity’ or ‘helps maintain normal cholesterol levels’ have not been evaluated by the Food and Drug administration. Therefore these tablets cannot be taken in place of any medication should you have a medical condition.
Hope this helps
