Synergistic Compounds


Compound Synergy Mechanism Evidence Rating
Tongkat Ali (Eurycoma longifolia) Both herbs appear to support testosterone production through different mechanisms. While Fadogia Agrestis may primarily stimulate luteinizing hormone (LH) production, Tongkat Ali appears to work through multiple pathways including inhibiting Sex Hormone Binding Globulin (SHBG) and supporting Leydig cell function. The combination might provide more comprehensive testosterone support, though this is theoretical and not clinically validated. 1
Ashwagandha (Withania somnifera) Ashwagandha may complement Fadogia Agrestis through stress reduction and cortisol management. High cortisol levels can suppress testosterone production, so Ashwagandha’s adaptogenic properties might enhance Fadogia’s testosterone-supporting effects by creating a more favorable hormonal environment. Ashwagandha also has better safety data, potentially offering a more balanced approach to hormonal support. 1
Zinc Zinc is an essential mineral for testosterone production and testicular function. Adequate zinc levels are necessary for the luteinizing hormone (LH) to effectively stimulate testosterone production. Theoretically, combining zinc with Fadogia Agrestis could enhance testosterone-supporting effects by ensuring the mineral cofactors needed for hormone synthesis are available. 1
Magnesium Magnesium supports testosterone production and is involved in hundreds of enzymatic reactions in the body. It may help optimize the effects of Fadogia Agrestis by supporting overall hormonal health and reducing Sex Hormone Binding Globulin (SHBG), potentially increasing free testosterone availability. Magnesium also supports sleep quality, which is important for testosterone production. 1
Vitamin D3 Vitamin D receptors are present in reproductive tissues, and optimal vitamin D status is associated with higher testosterone levels. Combining with Fadogia Agrestis may provide synergistic effects on testosterone production, though this is theoretical and not clinically validated. 1
Boron Boron helps increase free testosterone by reducing Sex Hormone Binding Globulin (SHBG) and supporting vitamin D metabolism. This may complement Fadogia Agrestis’s effects on testosterone production by enhancing the bioavailability of the testosterone produced. 1
Fenugreek Fenugreek contains compounds that may inhibit 5-alpha reductase and aromatase enzymes, potentially reducing the conversion of testosterone to DHT and estrogen, respectively. This could theoretically enhance the net testosterone-boosting effect of Fadogia Agrestis by helping maintain higher levels of the testosterone produced. 1
Tribulus Terrestris While Tribulus has limited evidence for directly increasing testosterone in healthy individuals, it may enhance libido and sexual function through other mechanisms. Combined with Fadogia Agrestis, it might provide complementary effects on sexual health beyond testosterone modulation alone. 1
Mucuna Pruriens Contains L-DOPA, a precursor to dopamine, which supports the dopaminergic system and may enhance mood, motivation, and libido. This could complement Fadogia Agrestis’s effects on sexual function through different neurotransmitter pathways. Mucuna may also support growth hormone and testosterone through dopaminergic effects on the hypothalamic-pituitary axis. 1
Antioxidants (Vitamin E, Vitamin C) Antioxidants may help protect testicular tissue from oxidative damage, potentially supporting the environment for optimal testosterone production. This could theoretically enhance the effectiveness of Fadogia Agrestis while potentially offering some protection against oxidative stress that might contribute to organ toxicity, though this protective effect is speculative. 1

Antagonistic Compounds


Compound Interaction Type Evidence Rating
Alcohol Alcohol consumption may counteract Fadogia Agrestis’s testosterone-supporting effects by increasing aromatase activity (converting testosterone to estrogen) and potentially causing oxidative stress in the testes. Additionally, both alcohol and Fadogia Agrestis may affect liver function, potentially creating additive stress on the organ. 2
Medications with known nephrotoxicity Given the potential kidney effects observed in animal studies with Fadogia Agrestis, combining with medications known to affect kidney function could create additive nephrotoxicity. This includes certain antibiotics (aminoglycosides), NSAIDs (especially with chronic use), some chemotherapy drugs, and certain antiviral medications. 2
Medications with known hepatotoxicity Animal studies suggest Fadogia Agrestis may affect liver function. Combining with medications that stress the liver could potentially create additive hepatotoxicity. This includes certain statins, some antibiotics, antifungals, and many other prescription medications with known liver effects. 2
Hormone-modulating medications Medications that affect hormone levels, including testosterone replacement therapy, estrogen medications, and certain prostate medications, may interact unpredictably with Fadogia Agrestis’s hormonal effects. This could potentially result in hormonal imbalances or reduced efficacy of the medications. 2
Licorice Root (Glycyrrhiza glabra) Licorice contains compounds that can lower testosterone levels and increase cortisol, potentially counteracting Fadogia Agrestis’s hormonal benefits. The glycyrrhizin in licorice has been shown to inhibit 17β-hydroxysteroid dehydrogenase, an enzyme involved in testosterone production. 1
Spearmint Tea Spearmint has demonstrated anti-androgenic properties in some studies, potentially reducing free testosterone levels. This may work against Fadogia Agrestis’s testosterone-enhancing effects. 1
Saw Palmetto (Serenoa repens) Saw Palmetto inhibits 5α-reductase, which converts testosterone to dihydrotestosterone (DHT). While this is beneficial for prostate health, it may interfere with some of the androgenic signaling that Fadogia Agrestis supports. 1
Estrogen-containing foods and supplements Foods high in phytoestrogens (such as unfermented soy products in large amounts) or supplements containing estrogenic compounds may counteract some of Fadogia Agrestis’s effects on hormonal balance. 1
Caffeine and other stimulants While not directly antagonistic to the testosterone effects, stimulants may compound any stimulatory side effects of Fadogia Agrestis. Additionally, excessive caffeine consumption has been associated with increased cortisol, which can negatively impact testosterone production. 1
Medications metabolized by cytochrome P450 enzymes While specific drug metabolism interactions with Fadogia Agrestis have not been studied, many herbal compounds can affect cytochrome P450 enzyme activity. This could potentially alter the metabolism of medications processed by these enzymes, though specific effects are unknown for Fadogia Agrestis. 1

Overview

The scientific evidence for Fadogia Agrestis is extremely limited, consisting primarily of a small number of animal studies and traditional use reports.

There is a notable absence of human clinical trials examining efficacy or safety. The existing research suggests potential effects on testosterone levels and sexual function in rodent models, but also raises significant safety concerns regarding kidney and liver effects. The lack of human studies, limited understanding of active compounds, and potential toxicity issues make the current evidence base inadequate for drawing firm conclusions about efficacy or safety in humans.

Key Studies

Meta Analyses
