Mechanism of Action: Ashwagandha lowers cortisol (stress hormone) and enhances relaxation, while Melatonin mimics the body’s natural sleep signals, helping induce sleep. Usage and Effects: Ashwagandha is suitable for long-term daily use, with effects building over time, whereas Melatonin is recommended for short-term use due to potential dependency risks. Side Effects: Ashwagandha may cause mild digestive issues, while Melatonin can lead to grogginess or dizziness if misused; both supplements interact with certain medications. Complementary Use: Taking Ashwagandha and Melatonin together can support stress relief and sleep quality, effectively managing anxiety-induced sleep issues.

Regarding supplements, Ashwagandha and Melatonin are popular choices for individuals looking to enhance their wellness routines. While each has distinct properties and uses, they offer potential benefits for managing stress, promoting relaxation, and more. This guide explores Ashwagandha and Melatonin, their unique benefits, key differences, and which might suit your wellness goals.

Did you know: In a study, adults aged 65-80 taking 600mg of Ashwagandha daily for 12 weeks reported enhanced sleep quality and morning alertness compared to a placebo. Ashwagandha’s withanolides reduce inflammation; animal studies show decreased inflammatory proteins like interleukin-10, with similar effects observed in human studies. In a study, 100 people with AMD took melatonin for 6-24 months, experiencing retina protection, delayed damage, and clearer vision retention. Melatonin may aid GERD treatment by reducing stomach acid secretion and decreasing compounds that relax the muscles between the oesophagus and stomach.

What is Ashwagandha and Melatonin?

Ashwagandha is an ancient Indian herb used in Ayurvedic medicine to combat stress; studies show it lowers cortisol and aids sleep. Melatonin, on the other hand, is a natural brain hormone produced at night that regulates sleep-wake cycles; it rises in the dark, signalling rest, and falls in response to light, promoting wakefulness. In addition to sleep regulation, Melatonin is a powerful antioxidant. 

Though different compounds, both Ashwagandha, made from shrub roots and berries, and synthetic melatonin supplements can improve sleep quality, especially in those with insomnia or irregular sleep cycles. Together or separately, the two work through different mechanisms to promote healthy, restful sleep.

Health Benefits of Ashwagandha and Melatonin

Below are the health benefits of Ashwagandha and Melatonin:

Ashwagandha

Here are the health benefits of Ashwagandha:

1. Relieves Stress and Anxiety

Perhaps the most well-known benefit of ashwagandha is its ability to reduce stress. A number of research studies highlight this benefit, showing that Ashwagandha can dramatically lower individuals' levels of stress and anxiety.

According to one study, Ashwagandha can also improve sleep quality; researchers found that participants who took the herb slept significantly better than those who took a placebo.

2. Improves Sexual Function in Women

Ashwagandha may help women with sexual dysfunction, according to at least one clinical trial. According to the reports, Ashwagandha treatment significantly increased their levels of arousal, lubrication, orgasm, and satisfaction. 

Along with improving measures of anxiety related to their sexuality and sex lives, it also markedly increased the number of successful sexual interactions.

3. Helps in Improving Sleep

Ashwagandha is sometimes taken to promote better sleep. According to one study, 65-80-year-old adults consumed 600mg of Ashwagandha root daily for 12 weeks. Compared to a placebo, it significantly improved their sleep quality and alertness on waking. 

A review of 5 quality studies also showed small but meaningful effects of ashwagandha on sleep. It enhanced overall sleep quality, reduced anxiety, and increased wake-time alertness. These benefits were greater for those with insomnia and those taking over 600mg of Ashwagandha for at least 8 weeks. 

So, evidence suggests Ashwagandha, especially in higher doses over 2 months, can aid sleep issues in older adults by decreasing anxiety and promoting sounder, more refreshing sleep.

4. Sharpens Focus and Memory

Ashwagandha may enhance cognitive function, memory, and the capacity to execute motor reactions upon instruction. In small trials, it has been shown to considerably enhance participants' reaction times during cognitive and psychomotor tests (which assess the ability to follow instructions and carry out a suggested activity) when compared to a placebo.

According to one study, Ashwagandha even considerably increased participants' attention spans and their immediate and general memory on several tasks.

5. Helps in Reducing Inflammation

Ashwagandha has compounds, including withanolides, that can decrease inflammation. Animal research found withanolides reduced inflammatory proteins like interleukin-10. Some human studies show similar anti-inflammatory effects. One recent study gave COVID-19 patients an Ayurvedic formulation with 0.5 grams of ashwagandha twice daily for a week. 

Compared to the placebo, it significantly lowered inflammatory markers C-reactive protein, interleukin-6, and tumour necrosis factor-alpha. So, Ashwagandha shows potential to combat inflammation through various mechanisms, as evidenced by decreased levels of key inflammatory biomarkers in both animals and humans. More research is still needed on optimal dosing.

Melatonin

Here are some of the health advantages of Melatonin:

1. Promote Eye Health

Studies show melatonin may also treat eye conditions like glaucoma and age-related macular degeneration (AMD). One study gave 100 people with AMD a melatonin supplement for 6-24 months. It helped protect the retina, delay AMD damage and maintain clear vision. 

Another study in rats found melatonin decreased the severity and frequency of retinopathy, an eye disease affecting the retina that can cause vision loss.

While this early research is promising for melatonin and eye health, more studies in humans are still needed to understand the long-term effects of melatonin supplements on eyes. However, the antioxidant properties show potential benefits for certain eye conditions.

2. Helps in Preventing Cancer

Melatonin has antioxidant properties that may help prevent certain cancers. It can limit DNA damage, leading to tumour growth. In addition, Melatonin may also disrupt cancer cell division and restrict blood supply to tumours. Some evidence finds melatonin reduces risk factors for hormone-related cancers like breast and prostate cancer. 

Additionally, Melatonin may help lower compounds that promote tumour blood vessel formation. More research is still needed, but Melatonin’s anticancer abilities, low toxicity, and various health benefits make it a promising supplemental cancer treatment through multiple mechanisms, such as limiting angiogenesis and proliferative signalling.

3. Helps in Insomnia

Insomnia sufferers struggle to stay asleep, fall asleep, or both. Chronic insomnia is the term used to describe symptoms that last for one month or more.

The American Academy of Sleep Medicine's (2017) and the American College of Physicians' (2016) practice guidelines state that insufficient solid evidence supports the use of melatonin supplements for treating persistent insomnia. The American College of Physicians guidelines highly recommend cognitive behavioural therapy for insomnia (CBT-I) as the first line of treatment for insomnia.

4. May Help Treat GERD

Gastroesophageal reflux disease (GERD) causes stomach acid to back up into the oesophagus, leading to symptoms like heartburn. Melatonin may help treat GERD in a few ways. It can reduce stomach acid secretion and lower levels of compounds that relax the muscles separating the oesophagus from the stomach. 

This prevents acid reflux. Studies show melatonin supplements alone or with traditional GERD medications can relieve heartburn and other symptoms. One study found a supplement containing Melatonin and other ingredients reduced GERD symptoms in more people than a common GERD medication alone. Due to its multi-pronged approach to acid reduction, Melatonin shows promise in supporting GERD treatment.

5. Cardiovascular Protection

The Mediterranean diet's cardiovascular benefits partially come from melatonin-rich foods. Most studies show Melatonin improves heart health against ischemia-reperfusion injury using high supplemental doses of melatonin. However, other research found physiological melatonin concentrations, like levels in red wine, can still significantly decrease infarct size after injury. 

This cardioprotective effect activates the SAFE pathway, which lowers mitochondrial reactive oxygen species. More research is still needed to determine if melatonin from foods alone at dietary levels provides the same cardiovascular protection as high-dose supplements or if higher amounts are necessary. However, current evidence confirms melatonin's role in promoting heart health.

Side-Effects of Ashwagandha and Melatonin

Here are the side effects of both Ashwagandha and Melatonin:

Ashwagandha

• Ashwagandha is likely safe for most when taken for under 3 months; long-term safety is unknown.
• It should not be taken if pregnant, breastfeeding, or with hormone-sensitive cancers, autoimmune disorders, thyroid disorders, or liver problems.

• Research shows Melatonin is safe for short- and long-term use in adults and is not addictive.
• Supplementation does not seem to decrease the body's natural melatonin production.
• It is not recommended for children or teens since long-term studies are limited to adults.
• Possible side effects include nausea, headaches, dizziness, and sleepiness.
• It can interact with some medications like antidepressants, blood thinners, and blood pressure medications.
• If taking these medications, talk to an Ayurvedic doctor before using Melatonin.
• Overall, it is considered safe for adults in the short and long term, but it is important to ensure appropriate use based on health conditions and medications.

Ashwagandha vs Melatonin: Which one to Choose?

Ashwagandha and Melatonin work differently but complement each other well for relieving anxiety and promoting sleep. Ashwagandha is an adaptogenic herb that helps the body deal with stress. It uplifts mood, lowers levels of the stress hormone cortisol, and induces relaxation, which in turn enhances sleep quality. On the other hand, Melatonin is a naturally occurring sleep hormone that helps control sleep and wake cycles. It helps manage anxiety levels and is useful for combatting excessive stress.

You can take Ashwagandha at night by mixing it in milk or opt for a supplement that contains effective doses of both Ashwagandha and Melatonin. It's best to take melatonin about 30 minutes before bedtime since, unlike pharmaceutical sleep aids, melatonin works gradually with your body's natural circadian rhythms. The combination of Ashwagandha easing anxiety and nervous system hyperactivity, along with Melatonin regulating sleep-wake cycles, can promote deeper, anxiety-free sleep.
