      The potency and number of NOW L-Arginine 1,000 mg (Double Strength) tablets if good for me. I don't like having to re-order all the time.

      Pros

      I just have to take one tablet a day and the bottle lasts 4 months.

      Cons

      Nothing.

      I purchased L-Arginine as part of the"DeannaProthocol". It is a treatment to hopefully slow the progression of ALS. The pill far too big to swallow so had to crush also hard to crush. Taste wasnt bad. Ok to eat mixed with applesauce.

      Pros

      Hoping it helps with ALS

      Cons

      Very big
