Furthermore, there was no statistically significant difference between the low-dose group and the placebo group on MVIC decline. The authors concluded that supplementation with 500 mg of PrimaVie per day improves muscle strength retention following exercise. Brown says that shilajit extract has traditional uses as an energizer and rejuvenator.
He expects it to become popular as an antiaging supplement. PrimaVie’s formula, he says, is designed to boost energy in men while promoting healthy skin and bones in women. While rhodiola (Rhodiola rosea) has a history stretching back to 1960s Russia, it originally gained interest for mood and libido support, and has only recently come to the fore as a potential adaptogen. Brien Quirk, director of R&D for Draco Natural Products (San Jose, CA), says that Russian adaptogens like Eleutherococcus senticosus may have immune-boosting and stress-reducing effects. “The term adaptogen originated in the USSR in the 1940s,” Quirk says. “A scientist by the name of Nikolay Lazarev discovered that schisandra (Schisandra chinensis) enhanced physiology to resist a wide range of adverse conditions and stresses.
People have started using the term adaptogen for almost any herb that seems to affect multiple physiological pathways; they’ve strayed from the original definition of maintaining homeostasis in the face of stresses.” Quirk says that rhodiola is an adaptogen in the classic sense, and modern research is beginning to explore this. One 2017 pilot study, an uncontrolled, open-label multicenter clinical trial, measured the effects of rhodiola supplementation on stress in 100 male and female subjects suffering from prolonged fatigue. Participants received two 200-mg tablets of the branded rhodiola extract Rosalin per day for eight weeks. Participants were assessed on the Multidimensional Fatigue Inventory 20, the Beck Depression Inventory II, the Recent Perceived Stress Questionnaire, and other measures at baseline and after 1, 4, and 8 weeks. After eight weeks, participants reported improvements in mood and energy, as well as declines in stress. While this pilot study lacked a control group—an important limitation—it does open up further avenues for future research, and it confirmed the safety and tolerability of rhodiola. This adaptogen remains on the fringe for now, but its promising early results in pilot studies justify further research that could increase its prominence. One little-known adaptogen that is showing promise as a mood booster is a member of the mint family found in India. Tulsi (Ocimum tenuiflorum) is a traditional herb commonly used in Ayurvedic medicine. According to Shaheen Majeed, president worldwide of Sabinsa (East Windsor, NJ), tulsi has several beneficial effects. “In Ayurveda, tulsi is classified as a ‘rasayana’, which means ‘lengthening of lifespan,’” he explains. “This herb is also known to be a revitalizer, mood enhancer, and antiaging remedy. Several studies have found that tulsi is helpful in fighting anxiety, depression, and stress, and it effectively regulates cortisol levels.” One 2017 literature review examined 24 clinical trials involving a collective 1,111 participants between the ages of 10 and 80. The trials reviewed ranged from 2 to 13 weeks in duration, and dosage ranged from 300 mg once per day to 14 g once per day. The literature review found that tulsi administration caused a statistically significant decrease in stress symptoms in two studies. Three other studies reported significant long-term reductions in stress and anxiety with higher doses administered over a longer timeframe. As more consumers seek out supplements that can relieve stress and boost immune function, adaptogens will only grow. Wellness industry experts predicted in 2019 that adaptogens would lead the wellness products industry in growth 6 , and market trends data has since proven them correct. Brands can capitalize on the growth of this category by promoting adaptogen products that have the support of robust clinical trials.
