Royal E – 15 ml

1. Royal E — 15 ml

The simplest shot in the Royal line: caffeine, acai, dextrose, potassium and vitamin B6 in 15 ml. No bitter orange, no liquorice, no kratom. If you want a straight energy lift for a night out without a complicated formula behind it, this is the one.

The Royal line is a set of 15 ml herbal shots built around one idea: liquid is absorbed faster than a capsule, so the onset is quicker and the response easier to judge. Each shot in the range is built on a different ingredient list, and they are not interchangeable.

Reported to keep you going for about four hours, which is the point of it. There is nothing exotic in the bottle and we would rather sell it on that basis than dress it up.

3. Counting your caffeine for the evening

This shot is caffeine-led, and the sensible way to use it is to think about your whole day rather than the bottle in isolation. The European Food Safety Authority considers single doses of up to 200 mg and daily intakes up to 400 mg to be of no safety concern for healthy adults. Those two numbers are the useful reference points:

The caffeine content of this bottle is not declared on the label, so treat it as a meaningful contribution to that daily total rather than a free extra — and do not put it on top of coffee and energy drinks across the same evening. That is the practical version of the warning, and it is more useful than a vague instruction not to combine stimulants.

3.1 The rest of the bottle

• Acai — a Brazilian palm fruit, included for flavour and its polyphenol content.
• Dextrose — fast-absorbing sugar. Immediate fuel, and part of why the onset feels quick.
• Potassium — an electrolyte, relevant on a night when you are sweating.
• Vitamin B6 — contributes to normal energy-yielding metabolism and to normal psychological function; one of the few permitted health claims in this category and a genuine one.

3.2 How to take it

1. Shake the bottle properly. The extract settles and an unshaken shot is not evenly dosed.
2. Take it an hour after a meal, not on a completely empty stomach and not straight after eating.
3. Drink half first and wait. This is the whole reason a 15 ml bottle is a sensible format — you get to see how you respond before committing to the rest.
4. Follow it with a glass of water, and keep drinking water through the evening.

4. Cautions

• 18+ only, no exceptions.
• A food supplement does not replace a varied diet, and the maximum dose on the pack is not a target.
• Do not stack it with medication, other stimulants, energy drinks or coffee.
• MAO inhibitors are the one hard no. The combination is dangerous.
• Not for anyone with a heart condition, high or low blood pressure, thyroid or kidney problems, or under treatment for depression, anxiety or nervousness.
• Do not use if pregnant or breastfeeding.
• Alcohol and stimulants together mean you feel less drunk than you are. Adjust accordingly.
• Overheating, not the capsule, is what puts people in trouble at a club. Water, rest and cool air.
• Keep away from children.

The bottle does not declare its caffeine, so count it against your day, not as a free extra on top of it.
