New Study Reveals How Much CBD You Should Be Taking Daily



As the popularity of hemp-derived products, particularly those containing cannabidiol (CBD), continues to surge, consumers are understandably seeking evidence-based guidance on their safe and effective use. In response to this growing need, a recent study has provided valuable insights into establishing daily intake limits for CBD isolate. If you've ever wondered how much CBD you should be taking daily, read on to discover the recommended guidelines based on this comprehensive assessment.

Details of the Study

The study in question set out to develop recommendations for the upper intake limits of CBD isolate for oral consumption. To achieve this, researchers analyzed a wealth of data from published human clinical trials and toxicity studies in animal models, all in accordance with established guidelines. The aim was to determine safe and acceptable daily levels of CBD intake for various population groups.

The Findings

Based on the rigorous evaluation of available data, the study arrived at several key recommendations:

  • Acceptable Daily Intake (ADI) for the General Population: For the general population, an ADI value of 0.43 milligrams of CBD per kilogram of body weight per day (mg/kg-bw/d) was established. This translates to approximately 30 mg of CBD per day for a typical 70-kilogram (154-pound) adult. This ADI is designed to cover a lifetime of CBD exposure from all sources, including food. It also takes into account the most sensitive subpopulations, including children.
  • Upper Intake Limit (UL) for Dietary Supplements for Healthy Adults: For healthy adults considering CBD dietary supplements with clear and accurate product labeling, an Upper Intake Limit (UL) of 70 mg of CBD per day was determined. This limit is based on potential reproductive effects observed in animal studies.
  • Alternative UL for Healthy Adults Excluding At-Risk Individuals: Healthy adults, excluding those attempting to conceive, pregnant, or lactating, have an alternative dietary supplement UL of 100 mg of CBD per day. This limit is established with a focus on liver effects. It is essential to note that this UL does not include individuals at risk for liver injury.
  • Further Consideration for the Exclusion of At-Risk Populations: In addition to the 100 mg/d UL, an alternative dietary supplement UL of 160 mg/d is suggested for the population that does not include individuals at risk for liver injury.

What Does This Mean for You?

The findings of this study offer valuable insights into the safe use of CBD for various population groups. For most adults, a daily CBD intake of up to 30 mg is considered acceptable for a lifetime of use, whether it's obtained from food or supplements. However, it's crucial to be mindful of product labeling and follow recommended dosage instructions.

For those specifically considering CBD dietary supplements, a limit of 70 mg per day is advisable for healthy adults, while an alternative limit of 100 mg per day can be considered if excluding individuals at risk for liver injury. This information provides a basis for making informed decisions regarding CBD usage and helps ensure a safe and enjoyable experience.


The study's evidence-based recommendations offer clarity on how much CBD you should be taking daily, catering to various population groups and potential health considerations. As with any dietary supplement, it's essential to exercise caution, follow product labeling, and, if in doubt, consult with a healthcare professional to determine the most suitable CBD intake for your individual needs. With these guidelines in mind, you can confidently incorporate CBD into your wellness routine, reaping the potential benefits while prioritizing your health and safety.
