        AmLexin, a Standardized blend of Acacia catechu and Morus alba, shows benefits to delayed onset muscle soreness in healthy runners

        Mesfin Yimam,Shawn M. Talbott,Julie A. Talbott,Lidia Brownell,Qi Jia 한국운동영양학회 2018 Physical Activity and Nutrition (Phys Act Nutr) Vol.22 No.4

        [Purpose] Sudden and exhaustive exercise causes muscle damage accompanied by oxidative stress and inflammation, leading to muscle fatigue and soreness. AmLexin contains a standardized blend of extracts from the heartwood of Acacia catechu and the root bark of Morus alba, and is known to possess antioxidant and anti-inflammatory properties. The aim of this study was to investigate the effects of this proprietary blend supplementation on muscular pain and redox balance in healthy runners, in comparison to a placebo. [Methods] A double-blind placebo-controlled clinical trial was carried out over 9 weeks in a single center. Thirty physically active male and female subjects within 18−70 years of age were randomized into AmLexin (mean age = 42.92 ± 2.48 and gender 7/5, male/female, respectively) and placebo (mean age = 41.15 ± 3.5 and gender 10/3, male/female, respectively) groups. Subjects were supplemented with 400 mg of AmLexin/day or a look-alike placebo during an 8-week training program, and for one week following a 13.1-mile half-marathon. Twenty-six subjects completed the 9-week supplementation trial. [Results] Results showed the AmLexin group experienced significantly lower levels of post-exercise pain on day 1−3 following the half-marathon compared to the placebo group. The AmLexin group also showed lower post-exercise oxidative stress and higher antioxidant capacity on days 1 and 6 following the half-marathon. These results demonstrated the rapid benefits of AmLexin on pain and oxidative stress within 1−6 days post-exercise. [Conclusion] Our data suggest that AmLexin could be a safe, effective botanical alternative for delayed onset muscle soreness.

        UP165, A Standardized Corn Leaf Extract for Improving Sleep Quality and Mood State

        Shawn M. Talbott,Julie A. Talbott,Lidia Brownell,Mesfin Yimam 한국식품영양과학회 2023 Journal of medicinal food Vol.26 No.1

        UP165, a standardized Zea mays (corn) leaf extract, was evaluated for its effect on sleep quality and overall well-being in a double-blind, placebo-controlled clinical trial, administered orally at 250 and 500 mg/day. Participants (n = 45) (age range 19–73) consumed the supplement or placebo ∼60 minutes before bedtime daily for 4 weeks. Measurements that were evaluated were as follows: daily sleep quality, as monitored by a fitness tracker; the Pittsburgh Sleep Quality Index (PSQI) for sleep quality and efficiency; salivary cortisol levels for stress; and Profile of Mood States (POMS) to assess general well-being. Participants who received UP165 showed a statistically significant and dose-correlated reduction in salivary cortisol (up to 36%); an increase in deep sleep time (up to 30 minutes); increased total sleep time (up to 10%); an improvement in sleep quality (up to 49%), and an enhanced POMS (36–58%). Participants in the UP165 group showed a sevenfold increase in deep sleep time and a 10-fold increase in PSQI sleep quality improvement compared to placebo. Collectively, UP165 is a safe nutritional supplement clinically proven for a 24-hour support with better quality and efficiency of sleep at night and an improved mood state and overall well-being during the day. The clinical study has been ISRCTN registered with study ID ISRCTN68282897.
