Saw palmetto is often discussed in the context of prostate health and hair loss prevention, but for natural lifters, one big question remains: Will saw palmetto hurt muscle gains? Since it blocks the conversion of testosterone to dihydrotestosterone (DHT), some worry that it might negatively affect strength and muscle growth. However, the reality is more nuanced.
How Saw Palmetto Works
Saw palmetto inhibits the enzyme 5-alpha reductase, which converts testosterone into DHT. DHT is a more potent androgen that plays a role in hair growth, prostate function, and potentially, muscle development. By blocking this conversion, saw palmetto may increase free testosterone levels, leading to a possible benefit in muscle growth. However, its actual effects vary from person to person.

Does Lowering DHT Affect Muscle Gains?
Some argue that since DHT is an androgen, reducing its levels could negatively impact muscle growth. However, there is no strong evidence suggesting that DHT is a major driver of muscle hypertrophy. Testosterone is the primary anabolic hormone responsible for muscle growth, and saw palmetto does not reduce total testosterone levels—it simply alters its conversion pathway.
What Do Studies Say?
The research on saw palmetto is mixed. Some studies suggest it can effectively lower DHT levels, while others show no significant effect on hormone levels at all. Because of these inconsistencies, it’s unclear whether saw palmetto meaningfully impacts muscle growth in natural lifters.
- Some evidence supports an increase in free testosterone, which could theoretically aid in muscle growth.
- No studies definitively show muscle loss as a result of taking saw palmetto.
- Some users report no noticeable difference in muscle gains or strength levels while supplementing with it.
Should You Worry About Muscle Loss?
For most natural lifters, saw palmetto is unlikely to hurt muscle gains. Since it doesn’t lower total testosterone and might even free up more testosterone, it could offer a slight benefit. If you’re worried about its impact, a simple way to find out is to try it for 3 months and track your progress.
Final Verdict
Saw palmetto is not a muscle-killing supplement. While it does reduce DHT, the evidence does not support a significant negative impact on muscle growth. If you’re considering taking it for hair loss, prostate health, or general well-being, you can do so without major concerns about losing muscle. Try it for a few months and assess whether you experience any benefits or drawbacks—it’s unlikely to hurt your progress in the gym.
