Ashwagandha Side Effects And Who Should Avoid It

Ashwagandha has surged in popularity as a natural stress-reliever and energy booster, but like any potent botanical, it's not suitable for everyone. Whilst research suggests this ancient adaptogen may support stress resilience and cognitive function, understanding its potential side effects and contraindications is essential for safe, informed use. If you're considering ashwagandha—or already taking it—knowing who should exercise caution can help you make the right choice for your individual health needs.

Most people tolerate ashwagandha well at recommended doses, yet certain groups should avoid it entirely or consult a healthcare professional before use. Pregnant and breastfeeding women are advised to steer clear, as ashwagandha may stimulate uterine contractions and insufficient safety data exists for nursing mothers. Those with autoimmune conditions such as rheumatoid arthritis, lupus, or Hashimoto's thyroiditis should also proceed with caution, as ashwagandha can potentially stimulate immune function. Additionally, individuals with thyroid disorders should monitor closely, since ashwagandha may influence thyroid hormone levels—sometimes beneficially, but requiring medical oversight nonetheless.

The Science Behind Ashwagandha Side Effects

Clinical studies generally report ashwagandha as safe when used appropriately, with side effects occurring in a minority of participants. The most commonly reported issues include mild gastrointestinal discomfort—such as upset stomach, diarrhoea, or nausea—particularly when taken on an empty stomach or at higher doses. Research published in peer-reviewed journals suggests these effects are typically dose-dependent and resolve when intake is reduced or taken with food. Some users report drowsiness, which makes sense given ashwagandha's traditional use as a sleep aid, but this can be problematic if taken at inappropriate times of day.

More serious considerations involve ashwagandha's potential interactions with medications. The herb may enhance the effects of sedatives, thyroid medications, immunosuppressants, and blood sugar-lowering drugs, creating risk of excessive sedation, hormonal imbalance, or hypoglycaemia. Those scheduled for surgery should discontinue ashwagandha at least two weeks beforehand, as it may interfere with anaesthesia and blood pressure regulation. Rare cases of liver toxicity have been reported in the literature, though causality remains difficult to establish—nonetheless, individuals with existing liver conditions should avoid ashwagandha or use it only under medical supervision.
