Coalition of CBD companies submits study on CBD absorption limits to FDA

A coalition of CBD-producing companies, ONE HEMP, whose goal is to mobilize Congress and the Food and Drug Administration (FDA), the U.S. food authority, presented U.S. authorities with a study showing that a maximum dose of 70 milligrams of CBD per day is safe for healthy adults. The study also showed that a maximum dose of 160 milligrams per day is safe for healthy adults who are not trying to conceive, pregnant or breastfeeding.

The study was submitted in response to a request for information from committees of the House of Representatives and the Senate, and was specifically designed to address concerns previously expressed by the FDA that the CBD is potentially harmful to the liver and reproductive health.

In a statement, Dr. Rayetta G. Henderson, principal investigator at ToxStrategies LLC, which conducted the study, said the research revealed that the suggested upper limits of CBD consumption for healthy adults «closely match the recommendations made by major regulatory bodies,» including Health Canada sets it at 200mg per day, the Therapeutic Goods Administration d’Australia, which sets it at 60mg per day and the Food Standards Agency in the UK, which puts it at 70mg/day.

Marcel Bonn-Miller, Ph.D., scientific director of Charlotte's Web and a member of the research team, said the study «will help inform legislators and regulators when determining manufacturing and labeling requirements for CBD-containing dietary supplements.».

«The implementation of scientifically-based safety limits is essential to protect consumers. This research also supports ONE HEMP's recommendations for accurate product labeling and, ultimately, for CBD companies to take responsibility for manufacturing and selling safe, quality products.» said Bonn-Miller in a press release.

Charlotte's Web, known for its shared history with Charlotte Figi, is a founding member of ONE HEMP, whose aim is to work towards stricter regulatory standards, including independent third-party testing and accurate labeling, the company said in a press release.

Jared Stanley, co-founder and COO of Charlotte's Web, said the CBD market needed «clarity and stability» and that 'it's time for Congress to clarify the FDA's mandate and definitively regulate CBD products as dietary supplements once and for all.».

The study submitted by ONE HEMP was published online on August 25 in the journal Regulatory Toxicology and Pharmacology.
