Suma Root (Pfaffia paniculata / Brazilian Ginseng)

Suma root (Pfaffia paniculata) is valued primarily for its bioactive compounds rather than macronutrient content. Key compounds include: **Pfaffosides** (triterpenoid saponins, approximately 11% of dry root weight, including pfaffosides A, B, C, D, E, and F), which are considered the principal active constituents responsible for adaptogenic and immunomodulatory effects. **Ecdysteroids** (notably beta-ecdysterone/20-hydroxyecdysone, approximately 0.63–0.7% of dry weight), plant steroids that support protein synthesis and may enhance athletic performance without androgenic side effects. **Pfaffic acid** (a nortriterpene), studied for potential anti-proliferative properties. **Germanium (organic Ge-132)**, a trace element found in concentrations higher than many other plants (estimated 0.001–0.01%), believed to enhance oxygen utilization at the cellular level and support immune function. **Vitamins**: contains vitamins A, B1 (thiamine), B2 (riboflavin), E, K, and pantothenic acid (B5) in moderate amounts. **Minerals**: notable levels of iron (up to ~4 mg/100g dry weight), magnesium (~200 mg/100g), zinc (~3 mg/100g), cobalt, silicon, and selenium in trace quantities. **Amino acids**: all 19 commonly occurring amino acids have been identified, with relatively high concentrations of arginine, histidine, and glutamic acid (total amino acid content approximately 5–8% of dry weight). **Polysaccharides**: approximately 10–15% of dry weight, contributing to immune-stimulating activity. **Stigmasterol and sitosterol** (phytosterols, ~0.1–0.5%) support cholesterol management and hormonal balance. **Allantoin** (~0.1%) contributes to tissue repair and anti-inflammatory activity. Fiber content is moderate at approximately 20–30% of the dried root. Protein content ranges around 8–12% of dry weight. Bioavailability notes: Pfaffosides and ecdysteroids are moderately bioavailable orally, though absorption of beta-ecdysterone may be enhanced when taken with a small amount of dietary fat. The organic germanium form present in suma is significantly more bioavailable than inorganic germanium. Saponins may enhance the absorption of other co-consumed nutrients by increasing intestinal permeability. Traditional preparation as a decoction or hot water extract improves polysaccharide and saponin extraction efficiency.
