Ashwagandha And Fish Oil Together: 5 Reasons Why You Should Take Them

According to some sources, you can take ashwagandha and fish oil together, but you must maintain a balanced diet.

Ashwagandha is an adaptogenic herb that may help reduce stress, anxiety, and inflammation.

On the other hand, fish oil is a good source of omega-3 fatty acids, which are crucial for brain health. It also has anti-oxidants that can help lower your risk of heart disease and cancer.

So, taking them together will breed good health benefits.

However, the research on the optimal dosage or timing of ashwagandha and fish oil intake is limited. So you should follow the instructions on the labels or your doctor’s advice.

Here are 5 research-based potential benefits of Ashwagandha and fish oil you may acquire.

Reason 1: Reduces Inflammation

Both ashwagandha and fish oil have anti-inflammatory properties and can protect you against several diseases like – heart disease, cancer, and Alzheimer’s.

A study showed that Ashwagandha may reduce C-reactive protein (CRP) levels—a marker of inflammation—in people with arthritis. Another study suggests that ashwagandha may lower the levels of pro-inflammatory cytokines—molecules that promote inflammation—in people with stress.

On the other hand, fish oil is rich in omega-3 fatty acids, known for their anti-inflammatory properties. Omega-3s are essential for maintaining the structure and function of brain cells and improving cognitive function and memory.

Besides, several studies have found that fish oil can reduce inflammation in people with rheumatoid arthritis.

Reason 2: Improves Brain Function

Ashwagandha has been used for centuries in Ayurvedic medicine as an adaptogenic herb. Studies show it can improve cognitive performance, including reaction time, discrimination, and vigilance.

On the other hand, fish oil’s omega-3s are crucial for brain cell structure and function, enhancing cognitive function and memory. DHA and EPA, two omega-3 fatty acids in fish oil, may improve cognitive function in a combined supplement at prescription levels in older adults with coronary artery disease.

Ashwagandha and fish oil can improve brain function by reducing inflammation and oxidative stress, protecting the brain, and enhancing cognitive function.

Reason 3: Boosts Immune System

Ashwagandha has shown immune-boosting properties in both animal and human studies. A study shows that ashwagandha may increase the production of infection-fighting white blood cells in mice. In another study, Ashwagandha may boost natural killer cell function to fight cancer.

Alternatively, fish oil also has immune-boosting properties. Numerous studies have found that fish oil can boost the immune system by increasing the production of white blood cells. It also can increase the activity of natural killer cells in people with cancer.

Thus, boosting the immune system with ashwagandha and fish oil can protect against infections and other diseases.

Reason 4: Reduces Stress and Anxiety

According to studies, ashwagandha reduces cortisol levels—a hormone released in response to stress—in people with chronic stress. Another study suggests that ashwagandha may reduce anxiety levels in people with anxiety disorders.

As for fish oil, it has stress-reducing properties. Several studies have found that fish oil can reduce anxiety levels in people with anxiety disorders and may reduce cortisol levels in people with chronic stress.

Hence, the combined effect of ashwagandha and fish oil is indeed great for managing stress and anxiety.

Reason 5: Promotes Heart Health

Both ashwagandha and fish oil may promote heart health. Ashwagandha may reduce cholesterol levels and triglycerides—two risk factors for heart disease.

On the other hand, fish oil can potentially reduce the risk of heart disease by lowering triglycerides, blood pressure, and inflammation.

If heart health is your concern, taking Ashwagandha and fish oil may help immensely.

The Recommended Dosage Of Ashwagandha And Fish Oil

The recommended dosage for ashwagandha and fish oil can vary depending on your needs and health condition. Most research suggests that taking 250–600 milligrams (mg) daily for at least 1 month may be beneficial.

As for fish oil, there is no recommended daily dosage for fish oil. However, consuming it may help you reach the daily recommended dosage of omega-3 fatty acids.

On average, a 1,000 mg dose of fish oil contains approximately 300 mg of both EPA and DHA combined. Most healthcare providers recommend 1 to 3 grams (1000-3000mg) of omega-3s daily.

A reminder: always check the label for EPA and DHA in fish oil supplements while buying them.

Can You Take Ashwagandha And Fish Oil At The Same Time?

The answer is not straightforward, as there is not enough scientific evidence to determine the safety and efficacy of this combination.

Some studies suggest that ashwagandha and fish oil may synergistically affect mood, cognition, and inflammation.

In contrast, others believe they may interact negatively and cause side effects such as insomnia, visual impairment, nausea, diarrhea, or bleeding.

And many often recommend taking ashwagandha and fish oil with some gap between them and a balanced diet.

But as everyone responds differently to supplements, you should consult your doctor before taking ashwagandha and fish oil together. It’s a must if you have any medical conditions or are taking any medications.
