What the literature actually says.
Below is a plain-language summary of the published research behind each of the six botanicals in AlphaFuel Pro. Where a study is cited, the canonical reference is the linked PubMed/NIH record — not the summary printed here.
- 01Tongkat Ali (Eurycoma longifolia)
A 2013 trial (Tambi et al., Andrologia) reported that 200 mg/day of standardized Eurycoma longifolia extract supported increases in free-testosterone levels in men with late-onset hypogonadism over a one-month observation window.
PubMed reference - 02Horny Goat Weed (Epimedium / icariin)
A 2010 review (Shindel et al., J Sex Med) summarized that icariin, the active flavonoid in Epimedium species, demonstrates PDE5-inhibitory activity in laboratory models — the same target class used in prescription circulatory medications.
PubMed reference - 03Stinging Nettle Root (Urtica dioica)
A 2007 study (Chrubasik et al., Phytomedicine) reviewed evidence that lignans from Urtica dioica root extract bind to SHBG (sex hormone-binding globulin), supporting free-testosterone availability without raising total testosterone.
PubMed reference - 04Saw Palmetto (Serenoa repens)
A 2009 Cochrane review (Tacklind et al.) examined trials of Serenoa repens extract in men with lower urinary tract symptoms, reporting comparable safety profiles to placebo across the included studies.
PubMed reference - 05Wild Yam Root (Dioscorea villosa)
A 2018 review (Cornejo-Garrido et al., J Ethnopharmacol) examined diosgenin — the principal saponin in wild yam — for its role as a steroidal-precursor cofactor in cellular signaling, particularly in older-adult populations.
PubMed reference - 06Sarsaparilla (Smilax officinalis)
A 2015 phytochemical review (Liu et al., Molecules) catalogued the saponin and flavonoid profile of Smilax species, with traditional and laboratory evidence for hepatoprotective and mild diuretic activity.

A note on framing.
The studies linked above examine each individual botanical in isolation. The AlphaFuel Pro formula combines them at researcher-cited doses, but individual outcomes vary. None of these references should be read as a treatment claim — they describe published associations, not promises.
