Ashwaghanda is in almost every testosterone support supplement, but can it actually do more harm?
Many supplement formulas include it to “increase” testosterone, but in reality that’s not what it does:
-Doesn’t raise T in women but can increase estradiol
-Can lower cortisol too much and cause fatigue, flat mood
-Can impact Serotonin and some women will feel emotionally blunted, unmotivated
Unless you have a hormone baseline, including s*x hormones and cortisol, I would not use it. Because you won’t know what’s actually changing and if you’re getting the benefits or not.
If you are looking for a more natural way to improve testosterone availability (free testosterone), consider Fenugreek:
-Supports free testosterone + libido
-Helps with glucose/insulin balance (key for SHBG)
-Actually researched for its benefits on testosterone and libido in women
Because Fenugreek can also increase estradiol along with testosterone, I would use this herb in the context of a hormone baseline—especially because women in perimenopause can have a huge spike in estrogen before it completely tanks.
Dose (based on research):
-500–600 mg/day of a standardized extract (often 50% saponins)
Ashwagandha can shift mood + estrogen in ways that don’t serve perimenopausal women and can actually make things worse.
Fenugreek is known to actually increase Free T and have a positive impact on libido in women. But just like with any other herb, proceed with caution while monitoring estradiol levels.
If you know your testosterone is low and your estradiol is low, then Fenugreek is a better choice. It just ends up being a nightmare when it is included in supplements with a kitchen sink of ingredients.
I only use specific herbs once I know my patient’s symptoms and lab results.
Final say:
Many supplements targeted for hormone balance or support have herbs that can backfire with mixed mechanisms. As I am in the process of creating my own formula for women, I am purposely avoiding herbs with unpredictable impact on hormones. Because you’re supposed to feel better, not worse!
