Warning: Hidden Dangers in Some Eria Jarensis Sports Supplements

Be aware that sports, energy, focus, and workout supplements that list the botanical ingredient "Eria jarensis" on the label may not be accurately labeled and contain undeclared stimulants or excessive caffeine, according to a recent study.

(See ConsumerLab’s Muscle & Workout Supplements Review or tests of related products as well as information about other dangerous stimulants that have been found in workout supplements.)

Eria jarensis is an orchid native to the Philippines that contains N,N-eimethylphenethylamine (N,N-DMPEA), a methamphetamine-like compound with stimulant effects, although also permitted in small amounts as a food flavoring.

Testing of 12 supplements (powders and pills) labeled as containing Eria jarensis and purchased online in the U.S. in 2021, found that about two-thirds of products contained N,N-DMPEAat levels of 0.1 mg to 41 mg per serving – and it was suspected that the compound may be added those with the highest amount. Interestingly, one-third did not contain N,N-DMPEA, suggesting that they did not contain Eria jarensis as listed.

One powder was also labeled as containing 100 mg of theobromine per scoop (15.9 grams) but was found to contain 4,319.6 mg per scoop -- 4,320 % the listed amount. This product also contained more caffeine than listed (439.7 mg vs 300 mg). On the other hand, another product, labeled as a preworkout powder, contained just 0.1 mg of caffeine instead of its listed 450 mg of caffeine per 14-gram scoop, and none of its promised 300 mg of Eria jarensis.

Some products contained very high levels of caffeine (up to 665 mg per serving) -- about six times the amount in a typical cup of coffee -- without disclosing this.
