menMD’s testosterone support supplement combines science and high-quality ingredients to formulate a supplement which may help improve a man’s testosterone naturally.* Our unique formulation is all natural, 100% vegan and made in the USA from globally sourced ingredients.
The Science Behind Our Ingredients
Indole 3-carbinol (I3C)
Indole 3-carbinol (I3C), the phytochemical found in cruciferous vegetables like cabbage, cauliflower, broccoli, brussel sprouts, kale, collards, mustard greens, radishes, watercress, and turnips. Indole-3-carbinol is the subject of ongoing biomedical research into its possible anticarcinogenic, antioxidant, and anti-estrogen effects.
Diindolylmethane (DIM), has been shown in scientific studies to reduce the risk of prostate and other hormone-driven cancers by helping the body to make a better balance of the hormones. Using DIM in men avoids accelerating testosterone metabolism, especially regarding unwanted conversion of testosterone into estrogen. In a study by Chen et al DIM prevented the tumors from growing, and this is because it lowers the level of estrogen.
Dehydroepiandrosterone (DHEA) decreases with age and this reduction has been shown to be associated with physical health in human. DHEA is the precursor to testosterone and estrogen. DHEA supplementation can elevate free testosterone levels in middle-aged men and prevent it from declining during high-intensity interval training.
Maca is the common name for Lepidium meyenii, a plant in the broccoli family. Studies have shown treatment with Maca improved sexual desire. Men supplementing maca have been known to experience an increase in sperm production.
Grape seed extract has been shown to inhibit aromatase enzyme in a dose-dependent manner via competitive and reversible inhibition. Similar results were seen by Eng et al where grape seed extract blocked estrogen synthesis by inhibiting the aromatase enzyme. The estrogen blocking mechanism was confirmed in-vivo by another study that demonstrated grape seed extract blocked aromatase expression in animal-model. grape seed extract works by stimulating the enzyme system that releases nitric oxide.
Zinc is by far the most important mineral needed for optimal testosterone production. Severe and moderate deficiency of zinc is associated with hypogonadism in men. Zinc plays an important role in modulating serum testosterone levels in normal men.
