Benefits and Potential Side Effects of Taking Ashwagandha Supplements

What is Ashwagandha?

Ashwagandha (Withania somnifera) is an ancient medicinal herb that has been used in India's traditional Ayurvedic medicine for over 3,000 years. The name ashwagandha comes from the Sanskrit language and means "smell of horse" - referring to the unique smell of the herb's root. Ashwagandha is also known by other names like Indian ginseng and winter cherry.

The ashwagandha plant is a small shrub with yellow flowers and orange-red fruit. The parts used medicinally are the berries and the root. Ashwagandha root has been used to treat a variety of conditions and promote overall health and longevity.

Potential Benefits of Ashwagandha

Modern science is beginning to find evidence to support some of the traditional health uses of ashwagandha. Here are some of the ways ashwagandha may benefit health:

Stress Relief

One of the most well-studied effects of ashwagandha is its ability to fight stress. Human and animal research has found it can lower cortisol levels and balance key neurotransmitters involved in the body's stress response.

Reduce Anxiety and Depression

Ashwagandha supplements may also help with mood disorders like anxiety and depression. Controlled studies note significant improvements in anxiety scores and depressive symptoms in people taking ashwagandha.

Support Brain Health

Some research shows compounds in ashwagandha, like withanamides and withanolides, can stimulate the growth of brain cells and protect the brain from degeneration. This could make it helpful for neurological conditions like Alzheimer's, Parkinson's and Huntington's disease.

Anti-Cancer Effects

Several studies have found ashwagandha root extracts can induce apoptosis (programmed cell death) in some types of cancer cells and may be useful as an adjunct therapy. More studies are still needed to confirm these effects in humans.

Improve Memory and Cognition

Ashwagandha has traditionally been used to boost memory and cognitive function. Recent research suggests compounds in the herb can promote nerve growth, protect the brain from oxidative stress, and preserve cognition especially in people with neurodegenerative diseases.

Increase Strength and Muscle Mass

In combination with strength training, supplementation with ashwagandha may support muscle growth and increased strength. The herb appears to similarly impact testosterone levels as some anabolic steroids, without the negative side effects.

Lower Cholesterol and Triglycerides

Several human studies have shown the ability of ashwagandha to reduce blood fats called triglycerides by 15-30%. It can also lower "bad" LDL cholesterol while increasing "good" HDL cholesterol. Together, this can support better heart health.

Regulate Blood Sugar Levels

Research suggests ashwagandha can mimic insulin, improve insulin sensitivity, and lower blood sugar levels. Supplementing with the herb, especially for people with diabetes or prediabetes, may aid glycemic control.

Increase Fertility and Libido

For men struggling with fertility issues, ashwagandha has been shown to balance key sex hormones like testosterone and luteinizing hormone. It also appears to improve overall semen quality. In women, ashwagandha may increase estrogen levels which can boost sexual function and fertility.

Possible Side Effects and Safety

When taken by mouth in typical doses, ashwagandha supplement is likely safe for most healthy adults. Side effects are rare but may include nausea, vomiting, and diarrhea. However, certain groups should use caution before taking ashwagandha:

Pregnant and Breastfeeding Women

There is insufficient reliable research on the safety of ashwagandha supplementation during pregnancy or breastfeeding. Therefore, it is best avoided during these times.

People with Autoimmune Diseases

Some research indicates compounds in ashwagandha could stimulate the immune system. People with autoimmune conditions like rheumatoid arthritis, lupus, or multiple sclerosis should first consult their doctor before taking ashwagandha.

People on Medications

Due to its effects on neurotransmitters, blood sugar, hormones and other systems, ashwagandha may interfere with certain medications like antidepressants, blood thinners, thyroid medications and diabetes drugs. It's important to talk with your doctor first if you take any medications.

People Having Surgery

It's recommended to stop taking ashwagandha supplements at least 2 weeks before any scheduled surgery because it may interfere with anesthesia and cause excessive drowsiness.

Ashwagandha Supplement Dosage

Typical supplement doses range from 150 mg to 1,000 mg taken once or twice daily. To see benefits like lower stress, improved memory and increased fertility, a good starting dose is around 300-500 mg standardized to contain 1.5% withanolides.

It's best taken with breakfast or lunch since ashwagandha can be energizing initially for some people. Evening doses could interfere with sleep.

Effects like reduced anxiety, lower blood sugar levels, and increased muscle mass are seen after at least 8 weeks of regular supplementation. Therefore, a minimum 3 month supplementation protocol is recommended.

Always follow dosage guidelines on your specific supplement product. And its best to buy high quality ashwagandha from reputable sources that test for purity and quality.

Maximizing Absorption

To increase the absorption and efficacy of ashwagandha supplements:

• Take with a meal containing healthy fats or black pepper
• Choose KSM-66 or Sensoril standardized extracts
• Select organic ashwagandha root powder when possible
• Buy from brands that provide third-party testing data

Putting it All Together

Ashwagandha is an impressive Ayurvedic herb that offers many evidence-backed health benefits from lowering stress and increasing vitality to boosting brain function. It has an excellent safety profile but still carries some moderate drug interactions that are important to be aware of.

In general, ashwagandha supplements can be a safe, natural therapy for reducing anxiety, supporting cognitive health, regulating blood sugar levels, and much more when taken properly and with the oversight of your integrative medical provider.
