No Vinpocetine in Some Vinpocetine Supplements; Picamilon Labels Not Accurate

A recently published study of 23 supplements listing vinpocetine as an ingredient found six did not contain any vinpocetine. Among those that did contain vinpocetine, most did not list amounts on the label, but amounts found in suggested daily servings varied by almost 100-fold, from 0.32 mg to 32 mg per day. 

The supplements were purchased in the U.S. from GNC and Vitamin Shoppe and were promoted for various uses, including memory enhancement, energy, muscle building and weight loss; brand names were not disclosed. The study was published in Drug Testing and Analysis.

Vinpocetine is an ingredient is some dietary supplements promoted to improve memory and cognition function, such as Procera AVH, and is sometimes added to Gingko biloba supplements. In Europe, vinpocetine is sold by prescription in doses of 5 mg to 40 mg.

Picamilon is promoted both as a pre-workout supplement and cognitive enhancement supplement. It is not considered a lawful dietary supplement ingredient in the U.S. Interestingly, in Russia, it is sold as a prescription drug. Analysis confirmed thirty of the 31 supplements labeled as containing picamilon contained the compound, providing recommended maximum daily servings from 2.7 mg to 721.5 mg (which exceeds amounts available by prescription). In supplements that listed a specific quantity of picamilon on the label, amounts actually found ranged 99.6 to 157.9% of the labeled amount.
