Is ashwagandha safe for seniors?
Ashwagandha is an adaptogenic herb used for thousands of years in Ayurvedic medicine to help the body manage stress and support overall vitality. For seniors, the question of safety is crucial due to age-related changes in metabolism, liver function, and the higher likelihood of taking other medications. Clinical studies have investigated the use of ashwagandha in older adults and generally found it to be well-tolerated in the short-term. However, the absence of extensive long-term safety data means that caution is warranted.
For most healthy adults, including those in their 70s, moderate and short-term use (up to a few months) is often considered relatively safe. Side effects are typically mild and may include gastrointestinal upset, drowsiness, or headache. However, seniors should be more vigilant for potential adverse effects and for specific, serious risks that have been documented in rare cases, such as liver injury and thyroid issues.
Benefits of ashwagandha for older adults
Research has explored several potential health benefits of ashwagandha that are particularly relevant to the elderly population. The herb's adaptogenic properties may help mitigate age-related decline in various ways:
- Improved Sleep Quality: Numerous studies have shown ashwagandha's ability to improve overall sleep quality and mental alertness upon waking in older adults. For many seniors who experience insomnia or non-restorative sleep, this can significantly enhance quality of life.
- Enhanced Cognitive Function: Some research indicates that ashwagandha supplementation may support cognitive functions like memory, attention, and executive function. This is particularly promising for individuals experiencing age-related cognitive impairment.
- Reduced Frailty and Improved Physical Performance: A placebo-controlled study demonstrated that ashwagandha root extract significantly improved walking speed, reduced frailty, and increased physical endurance in older adults. The herb's anti-inflammatory and antioxidant effects may contribute to reduced muscle damage and improved recovery.
- Stress and Anxiety Reduction: As an adaptogen, ashwagandha helps the body cope with stress, which can lead to reduced cortisol levels and lower anxiety. This can be a valuable benefit for seniors dealing with emotional or psychological stress.
Drug interactions and other precautions
Before a 70-year-old takes ashwagandha, a thorough discussion with a healthcare provider is non-negotiable. This is especially true if the individual is on any medications, as several significant drug interactions have been identified:
- Diabetes Medications: Ashwagandha can lower blood sugar levels. Taking it alongside insulin or other diabetes medications could cause hypoglycemia (blood sugar levels dropping too low).
- Blood Pressure Medications: The herb may also lower blood pressure. Combining it with anti-hypertensive drugs could lead to dangerously low blood pressure.
- Thyroid Hormone Medication: Ashwagandha may increase thyroid hormone levels. This can interfere with the regulation of thyroid function, making it risky for those with thyroid conditions or taking thyroid medication like levothyroxine.
- Immunosuppressants: Ashwagandha has been shown to potentially enhance immune system activity. Individuals on immunosuppressant medications for autoimmune diseases or organ transplants should be extremely cautious, as this could counteract the effects of their medication.
- Sedatives: The calming properties of ashwagandha can increase drowsiness. Combining it with sedatives, such as benzodiazepines or sleep medications, could lead to excessive sedation.

Safe use and conclusion
For a 70-year-old considering ashwagandha, the path forward must be guided by prudence and medical supervision. The potential benefits for improving sleep, cognitive health, and physical vitality are promising, but the risks of side effects and serious drug interactions cannot be overlooked. A personalized approach, which begins with a healthcare consultation, is the only responsible way to proceed. Your doctor can help determine an appropriate use, monitor for interactions, and ensure the supplement is suitable for your overall health profile. By prioritizing safety and expert guidance, seniors can explore herbal remedies like ashwagandha with confidence.
Finding quality ashwagandha products
Because dietary supplements are not strictly regulated by the FDA, product quality can vary significantly. To ensure safety, seniors should choose products from reputable brands that undergo third-party testing. Certifications from organizations like USP or NSF International can provide assurance of a product's purity and potency. Look for ashwagandha root extracts standardized to contain a specific percentage of withanolides, such as KSM-66, which has been used effectively in many clinical studies involving older adults.
Choosing quality supplements is crucial for safety and efficacy.
