Should Ashwagandha Be Taken Every Day?

Ashwagandha, or Withania somnifera, is an adaptogenic herb used in Ayurvedic medicine. It offers potential benefits for stress, cognitive function, and physical performance. The question of daily use requires examining its benefits, risks, and scientific evidence.

Ashwagandha has been used for centuries in traditional medicine. Its popularity has surged due to its potential health benefits. However, understanding whether it should be taken daily involves a closer look at its effects and safety.

Benefits of Ashwagandha

Ashwagandha is known for reducing stress and anxiety. Studies show it can lower cortisol levels, the stress hormone. According to a study in the African Journal of Traditional, Complementary, and Alternative Medicines, ashwagandha significantly reduced stress and anxiety levels. Another study found that taking 300 mg of ashwagandha extract twice daily for 60 days significantly reduced stress and anxiety (Everyday Health).

Immune System Support

Ashwagandha may enhance immune function. A randomized, placebo-controlled, double-blind study found that participants who took 60 mg of ashwagandha extract daily for 30 days showed increased activity of immune cells and molecules like immunoglobulins and cytokines. This suggests ashwagandha could help the immune system fight infections better.

Physical Performance

Research highlights ashwagandha’s potential to improve physical performance. A study involving athletes showed significant improvements in cardiorespiratory endurance, such as maximal aerobic capacity and time to exhaustion (NCBI). The athletes also experienced lower serum cortisol levels, indicating reduced stress.

Cognitive Function

Ashwagandha has neuroprotective properties that may benefit cognitive function. Some studies suggest it can improve memory and cognitive abilities, though more research is needed to confirm these effects.

Potential Risks and Side Effects

Most studies indicate that ashwagandha is safe for short-term use, typically up to three months. A randomized, double-blind, placebo-controlled trial involving 80 healthy individuals found that taking 300 mg of ashwagandha twice daily for eight weeks was safe, with no significant differences in health parameters between the ashwagandha and placebo groups.

Long-Term Safety

The long-term safety of ashwagandha is less well-established. While short-term use appears safe, there is insufficient evidence to determine its safety for periods longer than three months. Some sources recommend avoiding long-term use until more research is available.

Potential Side Effects

Ashwagandha is generally well-tolerated but can cause side effects in some individuals. Common side effects include upset stomach, diarrhea, and headache. In rare cases, liver injury has been reported, possibly due to contaminants in unregulated supplements (Good Housekeeping). Consulting a healthcare provider before starting ashwagandha is crucial, especially for those with underlying health conditions or taking other medications.

Special Populations

Certain populations should avoid ashwagandha. These include pregnant and breastfeeding women, individuals with autoimmune or thyroid conditions, and those who are immunocompromised or about to undergo surgery (Forbes). Ashwagandha can affect hormone levels, posing risks during pregnancy and breastfeeding.

Dosage Recommendations

The recommended dosage of ashwagandha varies depending on the form and intended use. For general well-being, a common dosage is 300-500 mg of ashwagandha extract per day, with withanolides in the range of 5-10% (Dr. Axe). Starting with a lower dose and gradually increasing it can help assess tolerance and effectiveness.

Specific Conditions

For stress and anxiety, a typical dosage is 300 mg of concentrated extract taken once or twice daily. For physical performance, doses up to 1,000 mg per day have been used in studies, though higher doses may increase the risk of side effects (Botanical Institute).

Forms of Ashwagandha

Ashwagandha is available in various forms, including capsules, powders, gummies, and tinctures. The appropriate dosage may vary depending on the form. For example, powdered root is typically taken in doses of 1-2 grams per day, while tinctures should be used according to the product’s specific instructions (Tribe Organics).

Key Takeaways

  • Ashwagandha can reduce stress and anxiety.
  • It may enhance immune function.
  • It can improve physical performance.
  • It has potential cognitive benefits.
  • Short-term use is generally safe.
  • Long-term safety is less certain.
  • Side effects can occur in some individuals.
  • Certain populations should avoid ashwagandha.


Ashwagandha offers promising benefits for stress reduction, immune support, physical performance, and cognitive function. However, its long-term safety remains uncertain, and more research is needed to establish its efficacy and safety for extended periods. Individuals considering daily ashwagandha supplementation should consult a healthcare provider, especially if they have underlying health conditions or are taking other medications. Pregnant and breastfeeding women, as well as those with autoimmune or thyroid conditions, should avoid ashwagandha. While ashwagandha offers promising benefits, it should be used with caution and under the guidance of a healthcare professional to ensure safety and effectiveness.
