Plain water does the job for most of us most of the time. But if you train hard, travel a lot or just find yourself sipping nothing but coffee until mid-afternoon, a flavoured electrolyte powder can be an easy way to drink more fluid. Spacegoods, the UK-based brand best known for its mushroom coffee alternatives, sells one called Hydro Dust.
This guide reads the Hydro Dust label the way you would before buying, explains the flavours and the creatine version, and flags who should think twice. All claims below are Spacegoods’ own, taken from its product pages on 25 October 2026, so check the pouch and the Spacegoods website for the latest details.
In this guide
What Is Hydro Dust?
Spacegoods describes Hydro Dust as an electrolyte blend that combines Himalayan pink salt, coconut water and real fruit powders with reishi mushroom, vitamin C, zinc and B vitamins. The brand says it contains no added sugar, with the sweetness coming from naturally occurring sugars in the fruit powders and from stevia. It is sold as a powder in pouches, in sachet boxes and in sample packs.
Reading the Label
The nutrition panel on the product page lists these amounts per serving. Spacegoods says one serving is a heaped teaspoon, or about one scoop, of powder.
| Ingredient | Per serving (as listed) | What the brand says it does |
|---|---|---|
| Sodium (from Himalayan pink salt) | 250 mg | A source of sodium, which the brand says supports fluid balance in cells |
| Potassium | 220 mg | An electrolyte that supports normal muscle function |
| Chloride | 497 mg | An electrolyte involved in fluid balance |
| Magnesium | About 52 mg on the label graphic | Balanced with potassium to contribute to electrolyte balance |
| Vitamin C | 80 mg | Supports immune function and protects cells from oxidative stress |
| Zinc | 3 mg on the label graphic | Supports immune function |
| B vitamins (B1, B3, B6, B12) | Listed at 100% of the reference intake | Support energy metabolism |
| Vitamin D3 | 10 mcg | Supports bones and immunity |
| Reishi mushroom extract | 1,000 mg | Described by the brand as supporting endurance and stress resilience |
One thing worth noticing: the text on the product page lists slightly different magnesium and zinc figures from the label graphic, so treat the numbers above as a guide and read the pouch you actually receive.
The Flavours and the Creatine Version
Spacegoods offers Hydro Dust in watermelon and pineapple, and describes both as fruity with a touch of salt. There is also an apple kiwi version that adds creatine monohydrate. The brand lists that one at 30 servings per bag with 3 g of creatine per serve.
| Version | Flavour | Notes from the brand |
|---|---|---|
| Hydro Dust | Watermelon | Electrolytes, vitamins and reishi, no added sugar |
| Hydro Dust | Pineapple | Same blend as watermelon, with pineapple fruit powder |
| Hydro Dust + Creatine | Apple kiwi | 30 servings per bag, 3 g creatine per serve, sweetened with stevia |
If you already take a creatine supplement, add up your total before choosing the creatine version, rather than doubling up by accident.
How Spacegoods Says to Use It
The instructions are simple. Add one scoop to a shaker, mix with cold water (the brand says 500 ml works best), shake well and drink. A stronger taste comes from using less water, and the brand’s own graphic suggests trying about 300 ml for that. Spacegoods says you can have it up to three times a day, for instance in the morning, after a workout or whenever you want a refreshing drink.
It is intended to be used alongside plain water rather than instead of it. The brand also says Hydro Dust can be used on the same day as its Rainbow Dust coffee alternative, so it fits around a morning hot drink if you like.
Where It Might Fit in a Day
- After exercise: sweat loses sodium and other minerals, which is what electrolyte drinks are designed to replace.
- Travel days: Spacegoods mentions long-haul flights as one use, since cabin air makes many people drink less.
- Hot weather or a busy office day: a flavoured drink can make it easier to keep sipping.
- Alongside coffee: a glass of fluid between cups is a sensible habit whatever you use.
Price, Delivery and Guarantee
Prices change often, particularly during sales. When checked on 25 October 2026, the UK page listed a Hydro Dust starter kit with free accessories on a first order at GBP 49 (shown against GBP 71), and a box of 10 sachets at around GBP 20. Spacegoods also lists a 60-day money-back guarantee and says it ships from a UK warehouse, with UK orders usually arriving within two working days of dispatch. The brand says its products are made in England, dual extracted and third-party tested.

Who Should Check With a Doctor First
A tasty electrolyte drink is not harmless for everybody. Each serving contains a meaningful amount of sodium and potassium, and reishi is a mushroom extract. Spacegoods itself says to speak with a doctor if you are pregnant or breastfeeding, and recommends asking a GP or healthcare professional about taking its products alongside prescription medication. Please also talk to a professional first if you:
- Have high blood pressure or are told to limit salt.
- Have kidney problems, or take medicines that affect potassium levels.
- Take blood thinners, diabetes medication or other regular prescriptions.
- Are giving it to a child.
Food supplements are not a substitute for a varied diet, and persistent tiredness or cramps are a reason to see your GP rather than reach for a powder.
Is It Worth Trying?
If you want a fruit-flavoured electrolyte mix that is easy to carry and low in sugar, Hydro Dust is a straightforward option, and the label is clear enough to compare with alternatives. Sample packs make it easy to try before committing to a full pouch. Compare the amounts, think about whether you need the added reishi or creatine, and check the current offer on the official Spacegoods store.
