In 2016, researchers from India published a paper on the anti-inflammatory effects of fenugreek . There was no disturbance in the sleep or behavior of the men. [49], This appears to be relevant in humans with Type I diabetes (100g defatted Fenugreek)[51] as well as Type II diabetics, where a 53% increase in insulin sensitivity was noted via HOMA relative to the control group using 1g daily of a hydroalcoholic extract. This dose roughly translates to 128mg/kg in humans. [89] The proposed mechanisms are through contractions of the uterine wall, which would also induce birth in the late third trimester. [34], A seed extract of fenugreek (IND01) given orally to rats at 50-200mg/kg for one month following spinal nerve damage (either a partial sciatic nerve ligation (PSNL) or a sciatic nerve crush injury (SNCI) injury) appear to reduce the hyperalgesia induced by the injuries following two weeks or supplementation, but not two days. [25], Fenugreek (300mg/kg of the seed powder for eight days in rabbits with the final dose an hour before testing) has failed to significantly interact with P-glycoprotein function as assessed by a cyclosporine tracer test. In one study, 30 college-age males received 500mg of fenugreek supplement daily. Yet, the study did find that the subjects decreased their serum dihydrotestosterone (DHT) levels. The study on mice also found the effects of the herb comparable to conventional medications for hair loss in mice. A few trials have been conducted on the matter, and fenugreek seems to be able to enhance milk production in recent mothers more than placebo. Despite no substantiated claims in human research models, fenugreek has been marketed in dietary products as having anabolic potential for resistance trained athletes.

[22] Another study with 30 men, found that a fenugreek extract, increased testosterone and bioavailable testosterone, but DHT did not change. [87] In another study, the LD50 was established at 3.5g/kg in female mice and 4.1g/kg in males. Concentrations of 1 to 10% of the compound were used on mice, and the herb is thought to be effective at these concentrations in humans as well. [22] Another study with 30 men, found that a fenugreek extract, increased testosterone and bioavailable testosterone, but DHT did not change. Researchers noticed increased testosterone and bioavailable testosterone levels, although estrogen and DHT … Anti-inflammatory, antioxidant, and cytotoxic properties have yet to be fully explored. DHT is anywhere between 2.5 to 10 times more potent than testosterone at activating androgen receptors in your body. The aromatic in fenugreek, sotolon, may be used as a diagnostic criteria for MSUD as it exists in the urine of those persons with this metabolic defect and gives the characteristic sweet-scent. And while studies on fenugreek have occasionally shown a mild increase in testosterone, these usually go hand in hand with a mild decrease in DHT. Xue, Wan-Li, et al. The team includes nutrition researchers, registered Bushey, Brandon, et al. In fact, researchers stated the following: Since that time, another study published in the Journal of the International Society of Sports Nutrition showed no influence in free or total testosterone levels from fenugreek extract. 5 January 2021, No adverse effects were noted in the infants given the breastmilk. Maple Syrup Urine Disease (MSUD) is a condition that results from improper metabolism of branched-chain amino acids.

[24], An ethanolic extract of fenugreek has failed to show affinity to the serotonin transporter (SERT) at concentrations up to 10mg/mL, suggesting no potential usage as an SSRI. The most well-known compound in fenugreek is 4-hydroxyisoleucine, which has been shown to help normalize the metabolism of glucose.12 8. [25], An ethanolic extract of fenugreek seeds appears to inhibit monoamine oxidase A (MAO-A) with an IC50 of 4µg/mL[4] and an extract containing high levels of trigonelline (84%) has shown MAOI properties with an IC50 of 528µg/mL (2.81µM assuming pure trigonelline). However, the group receiving 500 mg of fenugreek daily significantly increased total testosterone (6.57%) and bioavailable testosterone (12.26%). [24], A high trigonelline extract (84%) has been noted to inhibit monoamine oxidase B (MAO-B) with an IC50 of 391µg/mL (2.1µM assuming pure trigonelline).
