The length of time you take sulforaphane depends on your individual goals and the recommended dosage. There is no set length of time you should take it, as research into long-term effects is still ongoing. In the short term, sulforaphane can be taken for a few weeks to months to support specific goals, such as supporting the body during a detox. For general, ongoing support, sulforaphane can also be used long-term as part of a daily supplement. It is recommended to regularly discuss use with a doctor, especially when taking sulforaphane in higher doses or for longer periods of time. This will help to ensure that no unwanted effects occur and that the benefits are optimally utilized.
