Ashwagandha’s calming effects on the nervous system may help with both sleep latency and quality. Dr. Misra attributes the herb’s sleep benefits to its withanolides, naturally occurring compounds that promote relaxation. “These compounds lower cortisol, which often keeps us awake, and help ease the body into a restful state,” she explains.
A 2019 study published in Cureus supports this, showing improved sleep quality and morning alertness for those taking ashwagandha extract.
Ashwagandha for your libido
“Ashwagandha is traditionally used to boost libido and improve sexual function,” Pascal Nourtier, a dietitian and nutritionist in Paris, told GQ France. It has increasingly been studied for its effects on libido and sexual wellness, likely due to its influence on stress, hormone balance, and circulation.
A 2015 study found that women who took high-concentration ashwagandha extract over eight weeks reported significant improvements in arousal, lubrication, orgasm, and overall satisfaction. Stress reduction and hormonal balance are likely key factors here.
Ashwagandha for thyroid support (especially in hypothyroidism)
Among its many benefits, ashwagandha’s impact on thyroid function stands out, particularly for those grappling with subclinical hypothyroidism. A 2018 study showed that 600 mg of ashwagandha root extract daily for eight weeks helped regulate TSH, T3, and T4 levels—key thyroid hormones.
Dr Manoj Kutteri, Medical Director and CEO of Atmantan Wellness Centre, recommends taking ashwagandha in the morning for thyroid support, ideally paired with zinc and selenium for maximum effect. These two nutrients are essential for optimal thyroid health.
Ashwagandha for cognitive clarity and memory
While ashwagandha’s role in supporting brain function is still under study, some promising research suggests it could improve memory, attention, and mental clarity. A 2017 study showed that those who took 300 mg of ashwagandha twice a day saw improvements in memory and information processing speed compared to the placebo group. It’s a potential ally for anyone looking to boost cognitive function, particularly in the face of stress.
Ashwagandha for strength and muscle recovery
Ashwagandha isn’t just a friend to the mind, it can also be a companion to your fitness goals. A 2015 trial showed that men who took 600 mg of ashwagandha daily while participating in resistance training saw greater gains in muscle strength and size and recovered faster than those taking a placebo. It could be just the boost you need to maximise your post-workout recovery.
Ashwagandha for blood sugar and insulin support
Recent studies have found that ashwagandha may play a role in regulating blood sugar levels. A 2024 review concluded that the herb significantly impacted fasting glucose and HbA1c levels, suggesting its potential to support metabolic balance. While the research is still in its early stages, ashwagandha could be a natural addition for those looking to manage blood sugar.
Ashwagandha for hair and skin health
This is where the science thins out. While you’ll find ashwagandha in plenty of Ayurvedic oils and serums, there’s no strong clinical evidence to suggest it directly improves skin clarity or hair growth.
