You've just received your bottle of CBD oil and one big question comes up: how many drops should you actually take? Finding the right dose is a precise art that depends on your individual profile.

Whether you want to support a better night's sleep or relax after a busy day, the golden rule is the same: "Start low and go slow". In this guide, we explain how CBD dosing works so you can approach it with confidence.

1. CBD and individual biology

Cannabidiol interacts with the endocannabinoid system (ECS), a large internal regulatory network. Because everyone's ECS is different, the response to CBD is highly individual. Factors such as metabolism, genetics and the density of CB1 and CB2 receptors influence how your body processes CBD oil. That's why a dose that suits one person may feel like too little for someone else of the same weight.

2. Calculate your dose in one click

To save you from complicated milligrams-per-drop maths, we've created an easy tool. Simply enter your weight and the strength of your oil (e.g. 5%, 10% or 20%) and you'll get a suggested starting dose so you can begin with peace of mind.

3. The 4 key factors in your dose

Before you start, keep in mind these four factors that influence how much you may need:

  • Your body weight: As a rule, the higher your weight, the more the CBD dose can be increased.
  • Product strength: A 20% oil is four times as strong as a 5% oil. With a high concentration, a single drop is sometimes enough.
  • Your goal: The dose people use for light relaxation can differ a lot from what they use in more demanding situations. For any health concern, talk to your doctor.
  • Body chemistry: Your natural sensitivity to cannabinoids plays a major role.

4. The step-up method

The most effective way to find your "sweet spot" is to increase the dose gradually. Start with a base dose (around 15 mg a day). If after 3 days you don't feel the effects you hoped for, increase your daily dose by 5 mg.

Repeat this process until you find the dose that feels right for you. Once you've reached it, there's no need to go higher.

5. Adjusting your dose to your goals

For sleep

If you use CBD as part of your bedtime routine, take it about 30 to 45 minutes before going to bed. Many people find a single, slightly larger dose in the evening works better for them than micro-doses spread across the day.

For stress and relaxation

Here, many people prefer splitting the dose. Taking a few drops in the morning, at lunchtime and in the evening helps keep cannabinoid levels steady through the day. If you experience anxiety, speak to a healthcare professional.

6. In summary

The essentials in a few points:

  • Use our calculator for a reliable starting point.
  • Listen to your body: if you're happy with the effects at 20 mg, don't go any higher.
  • Consistency is key: CBD can take a few days before you notice its full effect.
  • Always choose ORGANIC quality to avoid contaminants.

Can I take CBD with other medication?
