Determination of the Potency of a Novel Saw Palmetto Supercritical CO2 Extract (SPSE) for 5-Alpha-Reductase Isoform II Inhibition Using a Cell-Free In Vitro Test System

Saw palmetto, a 5-alpha reductase inhibitor, caused unexpected side effects like breast changes and altered semen consistency, which resolved after stopping its use. Concerns about similar side effects with finasteride or dutasteride were expressed, and another user reported low libido and depression from saw palmetto.

The conversation is about determining which type of Saw Palmetto, either Chamaerops humilis or Serenoa repens, is effective for inhibiting the 5 alpha reductase enzyme related to hair loss. Specific treatments mentioned are Minoxidil, finasteride, and RU58841.

Finasteride is the most effective treatment for reducing DHT and addressing hair loss compared to fish oil and saw palmetto. Topical treatments like RU58841 and minoxidil are also discussed, but finasteride remains the most effective option.

Saw palmetto, particularly the standardized extract with 85% fatty acids, is discussed as a potential hair loss treatment, but opinions on its effectiveness vary. Some users combine it with other treatments like finasteride, minoxidil, and ketoconazole, noting mixed results in hair retention and shedding reduction.

Zinc picolinate and saw palmetto may lower DHT but are less effective than finasteride. Finasteride and minoxidil are preferred treatments, with ketoconazole shampoo as a suggested addition.

The user experienced anxiety and side effects from topical finasteride and is considering switching to saw palmetto. Another user reported no improvement with saw palmetto and experienced liver issues.
