Fadogia Agrestis

Adaptogens

Mechanism

Fadogia agrestis stem extract contains saponins and alkaloids that appear to increase luteinizing hormone (LH) release from the anterior pituitary, stimulating Leydig cell testosterone production. Animal studies suggest it may also have direct effects on testicular steroidogenic enzymes and may increase testicular weight. The saponin content may modulate gonadotropin-releasing hormone (GnRH) pulse frequency. The aphrodisiac effects are likely mediated through increased testosterone and possibly direct effects on dopaminergic and nitrergic pathways.

Standard Dosing

400-600mg daily

Timing

Morning with food.

Cycle Duration

Cycle 4-8 weeks on, 2-4 weeks off (limited long-term safety data)

Side Effects

  • Limited human safety data
  • Testicular toxicity at high doses in animal studies
  • Potential liver stress
  • GI discomfort
  • Insomnia

Contraindications

  • Hormone-sensitive cancers
  • Testicular pathology
  • Pregnancy/lactation
  • Children/adolescents
  • Liver disease

Mechanism

Zinc is a cofactor for >300 enzymes and is a structural component of >2000 transcription factors (zinc finger proteins). It is essential for: immune function (T-cell maturation, NK cell activity, neutrophil function), DNA synthesis and repair, protein synthesis, wound healing, taste/smell perception, insulin storage and secretion (zinc-insulin hexamer in beta cells), testosterone synthesis (cofactor for 17-beta-hydroxysteroid dehydrogenase), and antioxidant defense (Cu/Zn-SOD, metallothionein induction). Picolinate chelation via picolinic acid (a tryptophan metabolite) enhances intestinal absorption via DMT1 transporters.

Standard Dosing

15-30mg elemental zinc (as zinc picolinate) daily

Timing

With food to minimize nausea. Separate from iron, calcium, and copper supplements by 2 hours. NOT with high-phytate meals.

Cycle Duration

ongoing (with copper balance — see notes)

Side Effects

  • Nausea (especially on empty stomach)
  • Metallic taste
  • Copper depletion (chronic high-dose without copper)
  • Headache
  • GI upset
  • Reduced HDL at very high doses

Contraindications

  • Copper deficiency (zinc will worsen it)
  • Concurrent penicillamine therapy without separation
