X-Zero caught my attention through a Facebook ad – specifically the Horus flavour with its Egyptian-inspired design, which is exactly the kind of thing that works on me. Swedish brand, UK market, big flavour range. Looked promising.
Then I dug a bit deeper into how they operate. And that’s where this review gets complicated.
This review is part of my Best UK Powdered Energy Drinks roundup, where I test everything with my own money and give you the honest picture. No marketing BS, no sponsored content. That’s the No BS Reviews promise.
Who Are X-Zero Energy?
X-Zero are a Swedish powdered energy drink brand operating in the UK market. They’ve got a large range of flavours (32 on the website at the time of writing) and a decent caffeine content per serving. On paper, they look competitive. The issues are in the details.
My Overall Score: 7/10
| Category | Score | My Thoughts |
|---|---|---|
| Taste | 8/10 | Some strong flavours, some absolute misses |
| Effectiveness | 8/10 | 200mg caffeine per real serving |
| Price | 8.5/10 | £0.70 per real serving — competitive |
| Grittiness | 10/10 | No grit at all |
| Range of Flavours | 10/10 | 32 flavours available |
| Marketing | 7/10 | Aggressive ads that attack other brands |
Taste – 8/10
The flavour range is where X-Zero does its best work. When the flavours land, they land well:
The best:
- Cola — 9/10
- Wild Strawberry & Strawberry — 9/10
- Pomegranate — 9/10
- Blackberry — 8/10
- Pear & Lemon — 8/10
- Rhubarb & Apple — 7/10
- Blue Raspberry — 7/10
The ones to avoid:
- Horus (Mango & Papaya) — 3/10 — The flavour that caught my eye in the first place. Awful aftertaste. Really disappointing.
- Cactus Lemon — 0/10 — Absolutely vile. Avoid at all costs.
The hit rate is decent enough overall, but Horus being a 3/10 stings given that’s what pulled me in. And Cactus Lemon is one of the worst things I’ve tasted in this entire series.
Effectiveness – 8/10
At 200mg caffeine per real serving, X-Zero matches Wraith Energy for the highest caffeine content among the brands I’ve tested. The boost is solid and comes without a harsh comedown – no complaints on effectiveness.
Price – 8.5/10
Working out the real price per serving requires some attention. X-Zero count one standard shaker as two servings in their marketing, which halves their advertised cost per serving and makes it look much better value than it is. Counting real servings properly, you’re looking at around £0.70 per serving from a tub, which is still competitive, just not quite as exceptional as they’d have you believe.
The sample pack postage has changed over time too – it was £4.99 at one point, has since been restructured so postage appears free, though the overall cost is now slightly cheaper. Worth being aware of.
Grittiness – 10/10
No grit noticed across any of the flavours I tested. Full marks — mixes cleanly every time.
Range of Flavours – 10/10
32 flavours is the biggest range of any brand in this series. On quantity alone, full marks. The quality across that range is more variable than Sneak or Wraith, but there are enough strong options in there that most people will find something they like.
Marketing – 6/10
This is where I have to be straight with you. X-Zero run Facebook ads that directly mock and attack other brands – including Sneak Energy. I don’t like that approach. It’s not the kind of thing a brand confident in its own product needs to do, and it makes me less willing to trust the claims they make about themselves.
The shaker and tub designs are plain compared to Wraith or Sneak. Nothing offensive, just unremarkable.
X-Zero Energy Pros and Cons
What I liked: Several strong flavours in the 8-9/10 range, completely grit-free, largest flavour range in the series at 32 options, 200mg caffeine per real serving, competitive at £0.70 per serving
What I didn’t like: Misleading serving count marketing, aggressive ads that mock competitors, Horus was a 3/10 despite being the reason I tried it, Cactus Lemon is one of the worst flavours I’ve tested, plain shaker and tub designs, historically poor postage pricing on samples
Is X-Zero Energy Worth It?
The drink itself is decent — some good flavours, solid caffeine, no grit, big range. If you judged X-Zero purely on what’s in the tub, it would score higher.
But I can’t separate the product from the practices. The misleading serving count marketing, the competitor-attack ads, the lack of transparency – these are things I can’t ignore on a No BS Reviews site. I don’t have a discount code for X-Zero and I have no interest in being affiliated with the brand.
It scores 7/10 overall and sits mid-table in my UK powdered energy drinks roundup. If you’re looking for a large flavour range with strong caffeine, Wraith Energy gives you 200mg caffeine, over 20 flavours and a brand you can trust — and code GEEKYGOREVAN gets you 10% off. Strafe Energy is my overall top pick at 9.5/10.
