Dose & Value Calculator

No two bottles are dosed the same way. Enter the weight, the goal, and what your product actually contains — you will get a starting dose, a titration ladder, and the real cost per day.

Adult CBD dosing is not strictly weight-based. Weight is shown for reference only — start at the low end whatever your size.

Your product

Most droppers are 20 drops per mL, but check yours. Potency and total mg are on the label; if they are missing, that is the first red flag.

Before you start — adults

  • Start low and increase only every 5–7 days. CBD builds slowly and the effect of one dose can run longer than you expect.
  • Hold oil under the tongue for 60–90 seconds before swallowing. Swallowed oil is absorbed far less efficiently.

Compare price per mg

Two bottles, same 1,000 mg, one at $30 and one at $80. Which are you actually buying?

Price per mg is the only honest way to compare two bottles: the same money buys anywhere from 4¢ to 20¢ of CBD per milligram. It says nothing about quality, so pair it with the product's COA before you decide.

This calculator is educational, not medical or veterinary advice. The ranges come from published research and clinical practice, but individual response varies and other medication changes the picture. For people, confirm with your doctor or pharmacist. For pets, confirm with your veterinarian — they know your animal's history and what else it is taking.
