In the episode about hair, you talk about Saw Palmetto (serenoa repens) saying that it has a relatively short half-life, and so it would be best to take 2 doses daily. Can I have a link to the source, the related study? I want to email a producer of a supplement suggesting they split their supplement into 2 tablets per day, as now it is 1 per day and this information suggests it is not the best. Thanks

I couldn't find a specific clip discussing the half-life and dosage frequency of Saw Palmetto from the Huberman Lab. To get precise information and possibly the related study, I recommend reviewing the full episode where the topic of hair was discussed.

You can revisit the episode titled How to Optimize Your Hair Growth, Health & Appearance, which covers various aspects of hair health, including supplements like Saw Palmetto. This episode might provide the details you need for your email to the supplement producer.

It appears there are no specific clips from the Huberman Lab discussing the best dosage for Saw Palmetto directly. Generally, Saw Palmetto is often recommended in dosages ranging from 160 to 320 mg per day, typically taken in two divided doses. However, for the most accurate advice tailored to individual needs, it's best to consult a healthcare provider.
