Supplementation with 400 mg per day doses of LN18178 (Tesnor), a proprietary composition manufactured by India-based Laila Nutraceuticals, led to increases in total and free testosterone levels in the LN18178-400 participants were 25.29% and 18.86%, respectively, from baseline
Significant improvements in the hand grip strength and mid-upper arm circumference were also recorded for herbal combination after 56 days of supplementation, according to findings published in the Journal of Dietary Supplements.
“The outcome effects of herbal supplementation on testosterone levels were not comparable to results from testosterone replacement therapy (TRT) recommended for hypogonadic males,” stated the researchers. “In contrast, our observation is comparable to the outcome of a recently reported clinical study that demonstrated the effect of an herbal ingredient (fenugreek extract) in increasing testosterone and significant improvements in muscle strength and body composition of the young male participants.”
The study indicates that the herbal blend may offer a new alternative to formulators of dietary supplements and sports nutrition products for men to safely increase their testosterone levels and enhance the effects of aerobic exercise.
The study was funded by India-based Laila Nutraceuticals
Study details
The researchers recruited 120 young men aged between 21 and 35 to participate in their randomized, double-blind, placebo-controlled study. The men were randomly assigned to one of three groups: 200 mg or 400 mg per day of LN18178 or placebo for 56 days. The herbal blend is standardized for punicalagin (from pomegranate) and theobromine (from cocoa). All participants were instructed to perform 40 minutes of aerobic exercise four days per week for the eight-week study.
