What is the typical dose of yohimbine found in supplements like Apex Force?
Executive summary
Most commercial yohimbine supplements sold to athletes and consumers deliver single‑capsule doses in the 2.5–10 mg yohimbine range, with many manufacturers and reviews highlighting 2.5–6 mg as common and 5 mg often recommended as a starting dose [1] [2] [3]. Labels and testing vary widely: Examine found actual yohimbine content can run from 25% to 150% of what the label states, so the "listed" dose and the "actual" dose frequently differ [4].
1. What brands and product pages say about dose — the marketing baseline
Manufacturers of mainstream supplements commonly state doses per capsule in the single‑digit milligram range: Force Factor advertises 75 mg of yohimbe bark extract that “yields a full 6 mg of yohimbine” per capsule [2], Apex’s product page (Enhanced Athlete Yohimbine) recommends starting at 5 mg per day to assess tolerance [3], and product roundups list products ranging from about 2.5–10 mg yohimbine per serving [5] [6].
2. What the scientific and clinical literature reports as an “effective” dose
Reviews and trials commonly use or recommend 2.5–5 mg as the effective oral dose for ergogenic or metabolic endpoints; some studies have tested a wider range up to 20 mg but most guidance centers on 2.5–5 mg [1]. Clinical resources note prescription yohimbine exists and that dosing and safety should be individualized [7].
3. Safety guidance and commonly advised starting amounts
Multiple sources advise beginning low to assess tolerance — many consumer pages and product labels advise starting at roughly 5 mg daily [3] [8]. Institutional resources have described 15–30 mg per day as a “safe daily amount” in some studies, but that range sits above what many single‑capsule products supply and should trigger medical oversight because of cardiovascular and neuropsychiatric side effects [9].
4. Label accuracy and real‑world variability — the manufacturing caveat
Independent analyses and consumer guidance warn that yohimbine content on labels is frequently inaccurate: Examine reports that many supplements either fail to list yohimbine or contain 25–150% of the listed amount [4]. WebMD and other health sites likewise flag frequent mislabeling and variability across yohimbe/yohimbine supplements [10]. That variability means a product claiming 5 mg could deliver far less or far more [4] [10].
5. Forms matter — yohimbe bark vs. yohimbine HCl and standardization
Products may list “yohimbe” (bark extract) or “yohimbine” (the alkaloid) and can be standardized to a percent of alkaloids (for example, 2% yielding a calculated mg of yohimbine) [11] [5]. Some brands sell pure yohimbine HCl with precise mg amounts; others sell bark extracts where total alkaloid content depends on standardization and extraction [5] [2].
6. Common dosing patterns used by consumers and reviewers
Fitness and supplement guides commonly recommend single‑capsule doses of 2.5–5 mg for most users, with more experienced users or higher‑potency products delivering 6–10 mg per capsule [1] [5] [6]. Force Factor positions 6 mg per capsule as an “optimal” marketed dose for their product [2] [12].
7. Competing perspectives and unresolved questions
Clinical reviews recommend 2.5–5 mg for effect [1] while some health‑system overviews describe higher “safe” ranges of 15–30 mg used in studies [9]. These are not identical viewpoints: the lower range reflects typical efficacious, marketed doses; the higher range appears in safety literature but would generally require medical supervision [1] [9]. Available sources do not mention Apex Force specifically by independent lab testing; Apex’s site itself recommends starting at 5 mg [3].
8. Practical takeaway for consumers and clinicians
Expect marketed single‑serving yohimbine doses between about 2.5 and 10 mg, with many brands and reviews centering on 2.5–6 mg and a common starting recommendation of 5 mg [1] [2] [3]. Because labels are often inaccurate and products vary between yohimbe extract and yohimbine HCl, verify exact alkaloid content and consider third‑party testing before assuming a product delivers its stated milligrams [4] [10].
Limitations: this analysis uses available product pages, reviews and reviews of clinical literature in the provided sources; independent lab reports on specific Apex Force products are not in the sources and therefore not addressed (available sources do not mention independent lab testing of Apex Force).
