Drink Featured: Redline Xtreme
Redline evolved from the concentrated VPX Redline Fat Burner (this was discontinued many years ago).
The parent company Vital Pharmaceuticals markets a number of brands: Bang Energy, Redline, and the VPX workout supplement brand.
In 2021 the Redline brand had the following primary products:
So what’s in this super-powered bottle of energy?
Caffeine, Yerba Mate, 5-HTP (5 hydroxy-1-tryptophan), Yohimbe, Evodiamine, and Vinpocetine. And a few other things (specifically electrolytes).
Yohimbe is a bark extract from a tree in Africa. It’s considered a natural aphrodisiac and sold here to treat impotency, dilate pupils, and stimulate fat loss. It can also mess with your blood pressure, so watch out.
Evodiamine is derived from a Chinese fruit called Evodia Rutaecarpa. Supposedly burns fat.
Vinpocetine is an alkaloid derived from a periwinkle plant. It is used in Europe, Japan, and Mexico to treat cerebrovascular and cognitive disorders. Some people claim it elevates metabolism, but with no proof.
And the interesting one in the group: 5-HTP. I made sure to spell it out, so the smart ones in the group have already figured out the key: Tryptophan. It’s the same stuff in turkey that makes you sleepy, and there’s scientific evidence of it.
The 5-HTP compound is sometimes used to treat mild depression as, somehow, it can increase serotonin levels. It can also affect appetite, which may be part of why they put it in here. The other part? When you’re jacking up a drink with this much caffeine, you’re going to get jitters and “scatterbrain.” This may actually cut the disconnected thoughts out and allow you to think normally, but still, give you the energy effects of caffeine.
Most of these highly caffeinated energy drinks and shots are designed to be used by people that have built up a tolerance to caffeine. They are to be used as a workout performance aid.
It is very easy to overdose on caffeine with these drinks. Be sure to check the symptoms of overdose.
They should not be consumed by the general public and definitely kept out of the reach of minors.
Always be aware of a drink’s ingredients and your own tolerance/sensitivity to caffeine before consuming any energy supplement you aren’t familiar with.
