However, that’s not all; yohimbe has also been making waves as a weight-reducing agent. Apparently, it is one of the commonest ingredients in commercially available fat-burners.
So, is yohimbine the wonder herbal product – causing increased male libido and fat loss at one go? Sounds too good to be true – you are probably right!
Let us find out!
Yohimbe is the active ingredient derived from the bark of the tree Pausinystalia yohimbe; Rauwolfia serpentina plants also contain yohimbe (Seifert, Schaechter, Hershorin, & Lipshultz, 2011).
While yohimbe is the herbal product, yohimbine is the more pure form which is available as a drug; it is used in the treatment of male impotence.
The active ingredient yohimbine hydrochloride (yohimbine HCl) is an ?-2 receptor antagonist – meaning it blocks the ?-2 adrenergic receptors. This increases blood flow to the extremities (arms and legs) and penis. As mentioned earlier, yohimbine HCl tablets are prescribed chiefly for male impotence.
As opposed to the purer yohimbine, yohimbe may be more specific to weight loss. It has long been suspected that in addition to yohimbine HCl, yohimbe bark may include other bioactive alkaloids; these may be responsible for loss of bodyweight.
Following mechanisms have been proposed for the action of yohimbe:
In a nutshell, the fat-reducing ability of yohimbe is due to:
The general recommendation yohimbe dosage is once daily before workout on an empty stomach. It is advisable to take yohimbe with plenty of water and to strictly keep within the recommended doses to avoid risk of serious adverse effects. Yohimbine on the other hand is taken three times a day.
Doses vary depending on whether you are using the herbal yohimbe or the purer yohimbine and the purpose for which it is used:
Thus, you’d need to take 6 pills if you weigh somewhere in the range of 70-75Kg.
Yohimbe (and yohimbine) has the potential to cause dizziness and light-headedness. Thus, activities like driving, operating machines and playing contact sports may prove hazardous.
Yohimbine (and most likely yohimbe) seems to interfere with and worsen pathological conditions like:
Caution is advised if used; it is best to consult your physician when using yohimbine/yohimbe if these conditions are present.
Yohimbine in low doses causes hypertension while a paradoxical fall in blood pressure is seen with higher doses.
Symptoms of yohimbe/yohimbine overdose are:
Also, the safety (of using either yohimbe or yohimbine) in pregnant and lactating states has not been investigated. Hence it makes sense to avoid these when pregnant or breast-feeding. Similarly, yohimbe and yohimbine are contraindicated in children and young adults.
Yohimbine has been extensively studies for its aphrodisiac properties. The same, however, cannot be said about the weight-reducing abilities of yohimbe. Despite this, yohimbe finds its way into a number of commercially available fat-burners.
Very few studies that have investigated the effect that yohimbe has on body weight and body composition, have come out with equivocal evidence.
Notwithstanding the inconclusive reports, it is of interest that most studies in the past have used the drug yohimbine rather that the herbal extract yohimbe. And, as stated earlier, the herbal extract may contain other alkaloids that may support weight loss. Despite this, it cannot be denied that there isn’t enough scientific evidence in favour of yohimbe.
Based on the current status of literature on yohimbe, we cannot say for sure that yohimbe causes weight loss –the evidence in favour of yohimbe seems to be inconclusive.
Further research is warranted before yohimbine is able to nail its status as a fat-burner.
