CBD DOSAGE CALCULATOR
A conservative starting-dose calculator for South African CBD users. Adjust body weight, experience level, and goal — get a personalised mg range plus the equivalent in practical dropper volumes.
Experience with CBD
Primary goal
Suggested starting dose
8 – 15 mg
per serving, once or twice daily
Equivalent to approximately 1.0–1.9 × 0.5 ml droppers of a 500 mg / 30 ml CBD oil
This calculator gives a conservative starting range based on body weight, experience level, and goal — not a medical prescription. Start low, hold for 5–7 days, and adjust in 5 mg steps. If you take prescription medication or have a diagnosed condition, speak to a healthcare professional before supplementing.

This calculator uses conservative mg-per-kg ranges from our CBD dosing guide. For more on CBD generally, see What is CBD? — or, if you're considering medical-grade THC tinctures, read Section 21 explained.
