An ancient root with modern research behind it.
Ashwagandha has been used in Ayurveda for thousands of years to help the body handle stress. Today it's one of the most researched herbs for stress, sleep and calm. River of Life includes ashwagandha root in every daily capsule, alongside turmeric and black pepper.
What is ashwagandha?
Ashwagandha (Withania somnifera) is a small shrub whose root has been used in Ayurvedic medicine for more than 3,000 years. It's known as an adaptogen, a plant that helps the body cope with stress.
What the research shows
Stress and cortisol
In a 60-day study of 64 adults, ashwagandha root extract lowered stress scores and cortisol compared with placebo. A 2019 trial in healthy adults found similar results.
Sleep
A review of five trials with 400 people found ashwagandha improved overall sleep, especially in people with insomnia.
Strength and recovery
In an 8-week study of men doing resistance training, ashwagandha improved strength and recovery.
Why the root matters
Most clinical studies used extracts made from the root, not the leaves. River of Life uses ashwagandha root.
How to take ashwagandha
River of Life capsules combine ashwagandha root with turmeric, black pepper, ginger and bromelain.
How to take it: 2 capsules daily with food. Give it at least 4 to 8 weeks of steady use, the same window most studies measured.

Safety and interactions
Who should avoid ashwagandha?
Don't take it if you're pregnant or breastfeeding. Talk to your doctor first if you have a thyroid condition, an autoimmune condition or liver problems.
Does it interact with medications?
It may interact with thyroid medication, sedatives, blood pressure and diabetes medication, and immune-suppressing drugs. The NIH Office of Dietary Supplements also reports rare cases of liver injury. Read our guide to ashwagandha interactions.
What if it doesn't work for me?
Unopened products can be returned within 30 days on your first order, so you can try it with confidence.
Where ashwagandha comes from
Ashwagandha grows in dry regions of India, the Middle East and parts of Africa. Its name comes from Sanskrit and refers to the root's earthy smell. In Ayurveda it's classed as a rasayana, a tonic used to support strength and calm.
What to expect week by week
Weeks 1 to 2
Take two capsules daily with food. Some people feel calmer in the evenings early on; many notice nothing yet.
Weeks 3 to 6
Changes in stress, sleep and mood usually build in this window.
Week 8
Most trials measured results at 8 weeks, so this is a fair time to decide whether it's working for you.
Who ashwagandha is for
Adults dealing with everyday stress who want plant-based support.
People whose stress affects their sleep.
Active people looking for support with strength and recovery.
Ashwagandha alone or in a formula?
Single ashwagandha capsules make sense if stress is your only concern. River of Life adds turmeric with black pepper, ginger and bromelain, so you also support your joints and digestion in the same daily habit.
More ashwagandha questions
Is it safe to take every day?
Studies of up to about three months found it generally well tolerated. Some people get mild stomach upset or drowsiness. If you plan to take it longer, check in with your doctor.
Can I take it with my thyroid medication?
Ask your doctor first. Ashwagandha may affect thyroid hormone levels.
Can men and women both take it?
Yes. Studies have included both men and women. Avoid it during pregnancy and breastfeeding.
Is it vegan?
Yes. River of Life is vegan and contains no fillers.
Ashwagandha root vs leaf
Ashwagandha supplements can be made from the root, the leaf or a blend. The root is the part traditionally used in Ayurveda, and it's what most human studies on stress and sleep have used. Leaf extracts contain a different balance of compounds called withanolides. When you compare products, check which part of the plant is used, how much extract is in a daily serving and whether the brand is clear about its ingredients. River of Life uses ashwagandha root, in line with the research, alongside turmeric with black pepper, ginger and bromelain.
Ashwagandha and women's health
Many women look to ashwagandha for stress and sleep during busy life stages. It should not be taken during pregnancy or while breastfeeding. If you're trying to conceive, talk to your doctor before starting any new supplement.
Quick answers
Does ashwagandha affect testosterone?
Some small studies in men reported changes in testosterone, but the evidence is limited. Don't use it as a hormone treatment.
Can I take ashwagandha with alcohol?
Alcohol can add to ashwagandha's relaxing effect and adds strain on the liver. Keep alcohol moderate and check with your doctor if you drink regularly.

Where potency meets purity
Anti-inflammatory power
Here's the secret: turmeric alone is good, but turmeric WITH black pepper? Game changer. Black pepper contains piperine, which supercharges turmeric absorption by 2,000%. Yeah, you read that right. Two thousand percent. Without black pepper, most of the turmeric just passes through your body. With it? Your body actually uses it. That's why every bottle combines these two powerhouses — because taking turmeric without black pepper is like buying a Ferrari with no gas.
Ashwagandha Roots
Ashwagandha roots are widely recognized as a powerful adaptogen, offering significant benefits for stress management by helping the body achieve homeostasis and promoting a sense of calm. This makes Ashwagandha an essential supplement for those seeking to enhance mental clarity, reduce cortisol levels, and support overall resilience against the demands of daily life.
Digestive aid
Used for millennia, Organic Ginger is an effective digestive aid that soothes the stomach and supports the gastrointestinal tract by alleviating nausea and indigestion.
Natural inflammation relief
Bromelain is a natural enzyme found in pineapple. It helps your body break down proteins and has been studied for easing swelling and supporting joint comfort, which makes it a natural partner to turmeric.
