Can someone tell me if a regular kitchen tablespoon utensil is the same as a measuring tablespoon. The reason I ask is that I bought 1 16 oz bottle of flax and it says the serving size for 1 tablespoon is 31 servings. So if I take 2 a day the bottle should last me for 15 and 1/2 days. So far I am on day 20 and still have a little left for a couple of more days ( and before you ask...no I am sure I am not using a teaspoon). I got a feeling I will have to buy a set of measuring spoons.
