The GNC (aka General Nutrition Centers) Liquid B-Complex Dietary Supplement is a must have for anyone seeking a B-Complex supplement. The liquid comes in a small (2 fl. oz.) dropper bottle, which makes the liquid easy to measure (one dropper full per serving) and take.
The liquid doesn't have a great fruity taste, but the taste isn't horrible, either. You could easily take the vitamin supplement alone if you didn't want to mix it into water or juice. I have had no problems or negative side effects from this supplement and when I take it regularly I find my energy levels are increased while my level of depression is decreased.
The small bottle is easy to carry and contains around 60 servings, which should last you around two months if you're supplementing with one serving per day. The vitamin supplement retails at $7.99 per bottle, so you're certainly getting a great deal.
