What is Ashwagandha?

ashwagandha powder

Ashwagandha, scientifically known as Withania somnifera, is an herb with a history in Ayurvedic medicine spanning over 6,000 years. Originating from India, Africa, and the Middle East, ashwagandha contains bioactive compounds such as alkaloids, flavonoids, and steroidal lactones. Withanolides, a specific type of steroidal lactone, is believed to be primarily responsible for the health benefits of Ashwagandha, also referred to as 'Indian Ginseng'. Studies have found that ashwagandha has a variety of benefits ranging from stress relief, lower blood sugar levels, sexual health, and fertility.

Benefits of Ashwagandha

1.    Alleviates stress and anxiety

Many consumers take ashwagandha for its stress management capabilities. Numerous studies support that ashwagandha benefits include reducing cortisol levels, the primary hormone associated with stress. Beyond its stress-relieving properties, ashwagandha supports overall well-being, mitigating the extensive effects that stress responses can exert on various bodily functions, including cognitive function, sleep, and immunity. 

Research has demonstrated the herb's potential benefits in reducing anxiety levels. In a study involving seventy-five participants, one group received 300 milligrams of ashwagandha standardized to 1.5% withanolides, while the other received a placebo. The results show that ashwagandha was especially beneficial to the treated group. The intervention demonstrated significant decreases to anxiety levels, accompanied by notable improvements in mental health, concentration, fatigue, social functioning, vitality, and overall quality of life compared to the placebo group.

Under conditions of stress, susceptibility to feelings of depression, anxiety, inflammation, and oxidative stress is heightened. Ashwagandha is believed to modulate the activity of the hypothalamic-pituitary-adrenal (HPA) axis, indirectly leading to a reduction in cortisol levels in response to stress stimuli. This mechanism contributes to ashwagandha's comprehensive approach to stress management and its potential impact on associated mental and physical well-being.  

2.    Enhances focus and memory

Research shows that ashwagandha holds promise in enhancing cognitive function, including memory and attention. In a small double-blind, placebo-controlled crossover study, volunteers were randomly assigned to consume either a single 400-milligram dose of ashwagandha or a placebo. The study revealed that the supplemented group experienced improvements in working memory and response times compared to the placebo group.

While preliminary studies have yielded positive results, further research is essential to establish conclusive evidence regarding the impact of ashwagandha on cognition. Ongoing investigations will contribute to a more comprehensive understanding of the cognitive benefits associated with ashwagandha supplementation.

3.    Improves sleep quality

If you struggle with sleep, ashwagandha may be a valuable aid in enhancing sleep quality. Studies suggest that ashwagandha could potentially boost the activity of GABA, an amino acid serving as the primary inhibitory neurotransmitter in the brain, known for its calming effects. In a randomized, double-blind, placebo-controlled trial, 150 healthy subjects received a daily dose of 120 milligrams of standardized ashwagandha extract for six weeks. The supplementation demonstrated a noteworthy improvement in overall sleep quality, specifically addressing non-restorative sleep conditions in the participants. 

4.    Improves female sexual function

In the realm of Ayurvedic medicine, ashwagandha has long been revered as a natural aphrodisiac with the potential to enhance sexual function. A randomized, placebo-controlled study involving 80 women aged 18 to 50 investigated the effects of standardized ashwagandha root extract. Participants were randomly assigned to receive either 600 milligrams per day of ashwagandha or a placebo for eight weeks. The results of the study demonstrated a significant improvement in various aspects of female sexual health among those receiving ashwagandha intervention. This improvement encompassed enhanced sexual desire, improved lubrication, heightened arousal, more satisfying orgasms, increased sexual satisfaction, and reduced pain. The findings highlight ashwagandha's potential as a valuable supplement for supporting female sexual well-being.

5.    Boosts fertility levels in men

Several studies have indicated that ashwagandha helps male fertility by elevating testosterone levels. In a particular study, administering 675 milligrams of full-spectrum ashwagandha root extract resulted in a significant improvement in critical factors for men's fertility, including sperm concentration and motility. Notably, infertile males treated with an ashwagandha supplement also experienced a substantial increase in semen volume.

Additional research supports ashwagandha's role in improving male fertility by enhancing semen quality. The proposed mechanism for this improvement involves ashwagandha's ability to augment enzymatic activity in seminal plasma, while concurrently reducing oxidative stress. These findings underscore ashwagandha's potential as a supportive measure for addressing male infertility concerns.

What is Rhodiola?

rhodiola rosea

Rhodiola rosea, or rhodiola, is another adaptogen that has gained popularity as a supplement. The adaptogenic herb enhances the body's resilience to physical, environmental, and chemical stresses. Originating from cold regions in Asia and Eastern Europe, it contains active compounds, salidroside and rosavin, known for balancing cortisol. Rhodiola is known for its long history of medicinal use in other cultures, such as Scandinavia and Russia, to improve mental performance via the herb’s anti-fatigue effects.

Benefits of Rhodiola Rosea

1.    Regulates mood and stress

Rhodiola rosea works with the HPA axis, a robust neuroendocrine mechanism overseeing various physiological processes, including responses to stressors. Specifically, it inhibits the enzyme monoamine oxidase A, responsible for degrading neurotransmitters like serotonin, dopamine, and norepinephrine. These neurotransmitters play pivotal roles in mood, motivation, and adrenaline levels. By preventing their degradation, rhodiola also contributes to enhancing and regulating overall mood.

A study investigated the effects of rhodiola rosea on male and female patients experiencing mild to moderate depression. In this randomized, double-blind, placebo-controlled trial, participants were divided into three groups for a 6-week assessment: group A receiving 340 mg/day, group B receiving 680 mg/day, and group C receiving a placebo. The study findings indicated that both dosages of standardized rhodiola extract led to notable improvements in overall depression, encompassing enhancements in insomnia, emotional stability, and somatization.

2.    Increases mental performance

Rhodiola exhibits a stimulating effect, enhancing energy levels and effectively addressing stress-related fatigue. This anti-fatigue attribute has demonstrated its ability to not only increase energy but also elevate mental performance. In a study involving 60 participants experiencing stress-related fatigue, those who received a daily dosage of 576 mg of rhodiola rosea extract showcased improvements in burnout and stress response. The study's conclusion emphasized that Rhodiola intervention has an anti-fatigue effect, enhancing mental performance. Specifically, the results highlighted improved concentration and a reduction in cortisol response to escalating stress levels in individuals experiencing burnout with associated fatigue symptoms.
