Tincture Measurement Dosage Calculator – Our tinctures are sold in 30milliliter bottles. The dropper included is 1milliliter. This makes our serving size is one milliliter. How many milligrams per dropper? 1st – Identify how many total milligrams in the bottle. Our tinctures come in 750mg, 1500mg, 2500mg, and 3500mg. For this equation let’s use the 1500mg bottle. (it doesn’t matter if it’s a Full Spectrum or Isolate) 2nd – Take your 1500mg and divide it by the number of servings of the bottle which is always 30 (30ml). There are 30 one-millimeter servings in the bottle. With this formula there are 50mg of CBD per dropper. TOTAL CBD IN BOTTLE / (divided by) NUMBER OF MILLILITERS IN BOTTLE (30) = MILLIGRAMS OF CBD IN A DROPPER 750mg bottle / 30 = 25mg cbd per dropper & 12.5mg in half dropper 1500mg bottle / 30 = 50mg cbd per dropper & 25mg in half dropper 2500mg bottle / 30 = 83.3mg cbd per dropper& 41.6mg in half dropper 3500mg per bottle / 30 = 116.6mg cbd per dropper & 58.3mg in half dropper Now, if you’re proper dosage of CBD is 25MG, and a single dropper of that 1500MG tincture contains 50MG, you’d simply fill the dropper halfway. Or another option is to purchase the 750mg bottle, however for pricing efficiency it may be best to purchase up depending on your budget. Of course, this method isn’t 100% accurate, but it is more accurate than not measuring at all. Remember, start with a small dosage and gradually increase until you find your perfect dosage.
