Straight answers·Effects
Nootropic ingredietns and their effects
No brand-speak. Just the ingredient, the amount and the effects.
| Ingredient | What it is | Per can | Effects |
|---|---|---|---|
| Caffeine | From green coffee bean | 125mg | Contributes to increased alertness and improved concentration |
| L-Theanine | Amino acid from green tea extract | 100mg | Claimed to sharpen the mind. The best-supported use is combining L-theanine with caffeine to reduce caffeine jitters while maintaining attention and alertness. |
| enXtra® | Galangal root extract | 300mg | Clinical evaluations assessing subjective fatigue scales confirm that users do not experience a rebound crash. In fact, studies show EnXtra blocks the rapid drop in alertness that typically happens when caffeine wears off. |
| Rhodiola | Arctic root | 500mg | Multiple double-blind, placebo-controlled studies on physicians on night shifts, students during final exams, and military cadets have shown that Rhodiola significantly improves mental fatigue, short-term memory, and concentration compared to a placebo. |
| Panax ginseng | Korean ginseng root | 500mg | Panax ginseng (also known as Asian or Korean ginseng) is an herbal supplement studied for its potential to improve cognitive function, support blood sugar management, and reduce fatigue, though clinical evidence varies by use case. |
| Vitamin B5 | Pantothenic acid | 75% NRV | Contributes to normal mental performance |
| B6 and B12 | B vitamins | 75% NRV | Contribute to the reduction of tiredness and fatigue |

Questions·Straight answers
Nootropic energy drinks, clearly explained.
What is a nootropic energy drink?
A drink that pairs caffeine with ingredients chosen for focus, such as L-Theanine, adaptogens or plant extracts. The term isn't legally defined, so read the label.
What is enXtra®?
A patented extract of alpinia galanga, a root in the ginger family. It contains no caffeine. Read what is enXtra®?
Are nootropic drinks safe?
For most healthy adults in sensible amounts. Keep total caffeine under 400mg a day. Not for under-16s, or pregnant or breastfeeding women. If you take regular medication, check with a pharmacist about rhodiola and ginseng.
Do nootropic drinks work?
The caffeine does: it contributes to increased alertness and improved concentration. Evidence for the other ingredients varies, and none has an authorised UK claim for focus.
is 100mg of L-theanine enough?
The 100mg of L-theanine will successfully take the sharpest, most uncomfortable edge off the caffeine
How is it different from a regular energy drink?
