Yohimbe dose ranges across clinical trials run from 250 mg standardized bark daily for tolerance testing up to 2,000 mg daily in research protocols. The 500 to 1,000 mg daily range fits most use cases, with timing, cycling, and tolerance testing as critical as total milligrams.
Quick Answer
Standard yohimbe doses: 250 mg test dose for first week, 500 mg daily morning for ED support, 500 mg pre-fasted cardio for fat loss, 500 mg + 500 mg split for combined goals. Cycle 4 to 6 weeks on, then 2 weeks off. Always start at 250 mg to test BP and tolerance.
Key Takeaways
- Trial doses range from 250 mg up to 2,000 mg standardized bark daily
- Start at 250 mg for 1 week to test BP and tolerance
- 500 mg morning is the standard daily preventive ED support dose
- 500 mg pre-workout works for fat loss with fasted morning cardio
- Cycle 4 to 6 weeks on, 2 weeks off to reset alpha-2 receptors
- Always avoid yohimbe at any dose with 1 BP medication or anxiety
Yohimbe Dose by Goal
Different goals call for different doses. The 1998 Ernst meta-analysis pooled trials using yohimbine 15 to 30 mg daily, equivalent to 500 to 1,000 mg whole bark with 6% standardization.[1]Ernst E, Pittler MH. Yohimbine for erectile dysfunction: a systematic review — J Urol 1998 View source

| Goal | Daily Dose | Timing |
|---|---|---|
| Tolerance test (week 1) | 250 mg | Morning, with food |
| Mild psychogenic ED | 500 mg | Morning, with food |
| Moderate psychogenic ED | 500 mg + 500 mg | Morning + evening |
| Stubborn fat loss | 500 mg | 30 min pre-fasted cardio |
| Pre-workout focus | 500 mg | 30 to 60 min pre-training |
| Combined ED + fat loss | 500 mg morning + 500 mg pre-cardio | 2 doses on training days |
Tolerance Testing: Always Start at 250 mg
Yohimbe is one of the few herbal supplements where individual tolerance varies dramatically. Some adults tolerate 1,000 mg with no symptoms; others react to 250 mg with anxiety or BP rise. Always test:
- Day 1 to 7: 250 mg morning with food. Monitor BP and heart rate twice daily, watch for jitteriness, anxiety, headache, racing heartbeat.
- Day 8 to 14: If well-tolerated, increase to 500 mg morning. Continue daily BP and pulse checks.
- Day 15-plus: Settle on 500 mg or split-dose protocol based on goal. If 500 mg causes any concerning symptoms, drop back to 250 mg or stop.
For a clean clinically relevant whole-bark option, yohimbe at standard 500 mg dose matches trial-tested doses in 1 daily vegan capsule.
Cycling: 4 to 6 Weeks On, 2 Weeks Off
Continuous daily yohimbe use beyond 8 weeks may lead to alpha-2 receptor adaptation, reducing effectiveness. Standard cycling resets receptor sensitivity:
| Phase | Duration | Action |
|---|---|---|
| Test phase | Week 1 | 250 mg daily, monitor |
| Active phase | Weeks 2 to 6 | 500 mg or split protocol |
| Rest | Weeks 7 to 8 | 2 weeks off completely |
| Reassess | Week 9 | Decide whether to repeat |
Common Dosing Mistakes
Six mistakes that explain why yohimbe does not work or causes side effects:
- Skipping tolerance test. Going straight to 1,000 mg invites side effects in 10 to 15% of new users
- Empty stomach for ED protocol. Take ED dose with food; only fat-loss dose is fasted
- Late evening dosing. Yohimbine is stimulating; doses after 4 PM disrupt sleep
- Stacking with high caffeine. 300-plus mg caffeine plus yohimbe raises anxiety risk
- Skipping cycling. Continuous use beyond 8 weeks reduces effectiveness
- No BP monitoring. Always check home BP for first 4 weeks of any new yohimbe protocol
The 2015 Cohen review of yohimbine supplements found significant adulteration concerns; choose products tested for identity and yohimbine content.[2]Cohen PA et al. Yohimbine content in dietary supplements — Drug Test Anal 2016 View source
Frequently Asked Questions
How much yohimbe should I take per day? +
Standard dose is 500 mg standardized whole bark daily for ED support, 500 mg pre-fasted cardio for fat loss, or split 500 mg + 500 mg for combined goals. Always start at 250 mg for the first week to test tolerance. Maximum useful dose is about 1,500 mg daily; higher doses raise side effect risk without added benefit. Cycle 4 to 6 weeks on, 2 weeks off.
Should I take yohimbe morning or night? +
Morning. Yohimbine is stimulating and raises sympathetic activity. Doses after 4 PM commonly disrupt sleep. For ED protocol: 500 mg with breakfast. For fat loss: 500 mg 30 minutes before fasted morning cardio. For split-dose ED: 500 mg morning + 500 mg early afternoon (before 2 PM). Avoid evening dosing entirely.
Can I take yohimbe on an empty stomach? +
Depends on goal. For fat loss, yes — fasted morning dosing is required because insulin from food blocks the alpha-2 antagonism mechanism. For ED support, take with food to reduce GI upset and stomach acid sensitivity. Many users feel jittery on empty-stomach ED dosing; food buffers this without affecting erectile benefit.
Can I take more than 1,000 mg yohimbe? +
Higher doses up to 2,000 mg daily appear in research, but produce no extra benefit beyond the 500 to 1,000 mg range while raising side effect risk. The plateau is at 1,000 mg per dose; doubling does not double the effect but doubles BP rise and anxiety risk. If 1,000 mg daily for 8 weeks produces no meaningful change, the issue is not dose.
How long should I take yohimbe for? +
Maximum continuous use is 6 to 8 weeks, then a 2-week rest. Continuous daily use beyond 8 weeks leads to alpha-2 receptor adaptation, reducing effectiveness. Most users follow 6 weeks on, 2 weeks off cycling for sustained benefit. Reassess after 1 to 2 cycles whether the protocol still helps; if no benefit at 12 weeks total, switch to other approaches.
Do I need to cycle yohimbe? +
Yes. Standard cycling is 4 to 6 weeks on, then 2 weeks off. This rest prevents alpha-2 receptor adaptation that reduces yohimbine effectiveness with continuous use. During off weeks, continue lifestyle support (sleep, stress reduction, training, hydration). Some users follow 1 week on, 1 week off pulsed dosing for fat loss; 4 to 6 weeks continuous works better for ED.
What if I miss a dose? +
Skip it if past 2 PM. For ED protocol, missing 1 morning dose has minimal impact since effects build over weeks. Take the next scheduled dose normally. Do not double up. For fat-loss protocol, missing the pre-cardio dose means skipping yohimbe-enhanced cardio that day; resume the next training session. Missing 2 days a week extends time-to-effect 30 to 50%.
Should I monitor BP on yohimbe? +
Yes, especially the first 4 weeks. Check home BP twice daily during week 1 of test dose, then once daily through week 4. Yohimbine raises systolic BP 5 to 10 mmHg and heart rate 5 to 10 bpm at standard doses. Stop yohimbe if readings consistently rise above 140 / 90 mmHg or pulse over 100 bpm at rest. Acceptable range is your baseline plus 10.
