A clear guide to the two-part Spacegoods set, how its daytime and evening blends differ, and what to confirm on the UK product page before ordering.
- The Day + Night Starter Kit pairs two separate drink routines
- Rainbow Dust is the coffee-style half of the bundle
- Sleep+ Magnesium gives the set its cocoa-led evening option
- Subscription and contents checks affect the real offer
- The paired kit suits routine builders more than cautious tasters
- The honest verdict
A paired drink routine can be convenient, but a “day and night” label does not tell you what is in the bags, whether either flavour appeals to you, and if the set is sensible if you already have one half.
Spacegoods groups its daytime Rainbow Dust with an evening blend in the Day + Night Starter Kit. The store’s listing describes the products and configurable options, but the choice still depends on whether coffee-style and cocoa-style powders fit your habits. This article is based on the product information published by Spacegoods, not hands-on use.
Heads-up: we earn a commission from some links in this article. It never changes the price you pay.
The short version: the kit is a convenient pairing of Rainbow Dust and Sleep+ Magnesium, intended for different points in the day. It makes most sense if you want both formats and are comfortable with the ingredients and recurring-order terms, if selected. If you only want to try one blend, a single product or sample format is a more focused starting point.
The Day + Night Starter Kit pairs two separate drink routines
The offer is a product bundle, not a coupon or a time-limited sale we can confirm. Spacegoods presents Rainbow Dust as the daytime part and Sleep+ Magnesium as the evening part. The product listing describes 30 servings per bag; check the current UK page to confirm the selected kit contents and bag size before placing an order. Start with the live Day + Night Starter Kit listing for the exact variant details.
That distinction matters: a bundled format saves the decision of assembling two separate products, but it also means buying into two flavours and ingredient profiles at once. A kit is most useful when both parts have a place in your normal schedule. The bundle page is also where to verify if the selected purchase is one-off or a subscription option.

Spacegoods offers individual alternatives too. The Day + Night option is only one way to order the range. If the daytime coffee blend is the only part that interests you, compare the Rainbow Dust starter kit with the bundle. If evening cocoa is the priority, inspect the Sleep+ Magnesium Starter Kit on its own. Those pages are useful references for checking whether the pairing is actually better suited to your routine than buying only one product.
Rainbow Dust is the coffee-style half of the bundle
The brand describes Rainbow Dust as a coffee-style powder combined with functional mushrooms and adaptogens. See its Rainbow Dust blend and format for the listed choices. That makes it a better fit for someone who already likes a flavoured coffee ritual than for someone who wants a plain black coffee or avoids the listed ingredients. The paired kit listing shows the blend in context. Spacegoods says the powder can be mixed with hot or cold water or milk, giving it more serving flexibility than a single hot-drink recipe. The Rainbow Dust page has the preparation details.
Check the selected flavour and its ingredients on the product page. The listing offers different flavour choices, and those can affect if the drink suits your preferences or dietary needs. Check each flavour selection before choosing. A flavour name is not a substitute for the ingredient panel, particularly if you avoid a specific sweetener, mushroom, or other component.

For shoppers trying to keep the first order narrow, the separate Rainbow Dust option makes it easier to assess one blend at a time. The Day + Night Samples may also be worth checking if the page confirms it contains the flavours you want. Treat sample availability and contents as variable; verify them on the store before deciding.
- Choose the bundle if you want both a coffee-style daytime drink and an evening cocoa blend.
- Choose Rainbow Dust alone if the daytime format is the main reason you are shopping.
- Check samples first if flavour uncertainty matters more than having full bags immediately.
Sleep+ Magnesium gives the set its cocoa-led evening option
The second component, Sleep+ Magnesium, is described by Spacegoods as a cocoa-based powder with peptides, mushrooms, and a tri-blend magnesium ingredient. It is designed as an evening drink, so it makes the bundle more than a two-flavour sampler: the company assigns the blend a distinct time and role in its routine. Review the product page for the full ingredients, serving directions, and any suitability notes.
Marketing language around sleep and relaxation should not replace a realistic expectation. The listing explains how Spacegoods positions the blend, but it cannot establish how an individual will respond. People managing a health condition, taking medication, pregnant or breastfeeding, or avoiding particular ingredients should check the label and seek appropriate professional advice when needed.

Buying Sleep+ separately can be the cleaner choice if you already have a daytime drink or simply want to inspect this blend first. Compare the Sleep+ kit details with the bundle and the single Sleep+ pouch listing. Confirm the selected version and serving guidance rather than assuming every pack uses the same configuration.
Subscription and contents checks affect the real offer
The product page lists the offer details and selected options. Spacegoods may show purchase formats or variant selectors on its page, so review these deliberately before adding the kit to your basket. A subscription can change how an order repeats; it is not automatically the right value choice if you have not tried the flavours or do not know your rate of use.

Before checkout, confirm these points in the live UK listing:
- Which blends and bag sizes are included in the selected option.
- Whether the order is one-off or recurring, and how to skip, edit, or cancel if subscription controls are shown.
- The ingredients, allergen notes, serving guidance, and preparation instructions for each powder.
- Delivery, returns, and any guarantee terms that apply to this order.
These checks are more useful than assuming a headline says everything. A benefit such as shipping or a gift, if shown, can have conditions and may not apply to every purchase type. We do not state a discount, code, or deadline here because the campaign information supplied for this article does not establish one. Check the basket and terms for the offer attached to your own order.
The paired kit suits routine builders more than cautious tasters
The bundle’s practical advantage is convenience: two products from one brand, with the brand’s day-and-evening framing already built in. That will appeal to shoppers who want both flavours, are comfortable reading functional powder labels, and prefer a ready-made pairing to separately comparing the range. The bundle page lets you see the selection in that context. Compare it with sample formats before choosing a larger set.
It is less compelling if you have no interest in one half, need a plain drink without added ingredients, or want to sample before committing. A simple decision check can help. The Rainbow Dust kit, Sleep+ kit, and Day + Night bundle each serve a different buying preference:
- Do you actually want a coffee-style drink and a cocoa-style drink?
- Do the listed ingredients suit your diet and existing routine?
- Will you use both bags before they become inconvenient to store or finish?
- Does the purchase format match how often you want deliveries?
Preparation tools are separate considerations rather than reasons to buy the set. For example, Spacegoods lists a pink frother, but the presence of that accessory in the range does not mean it is included with this kit. Check the kit contents and any add-ons independently. The same applies to samples or gifts: only count what the product page and basket clearly include.

The store’s wider range includes other formats, but they should not blur the bundle’s core proposition. Focus on the two bags and the terms attached to them, then treat any accessories, chews, or extra products as separate selections. If a page suggests a free extra, confirm the qualifying order and whether the item appears in the basket before relying on it.
The honest verdict
The Day + Night Starter Kit is a clear fit for someone who wants Rainbow Dust’s coffee-style blend and Sleep+ Magnesium’s cocoa-led format in one purchase. Its main benefit is a coordinated pair, while its main limitation is equally clear: buying a bundle means accepting both products, their flavours, and their ingredients. We would start with the separate blend or a sample if either half is uncertain.
Use the UK product page to confirm the latest pack contents, purchase type, and order terms. If both routines suit you and the listing still matches what you expect, the kit is a straightforward way to get the paired range. If not, choose only the product you are likely to use.
Choose the Day + Night kit when you want both blends; otherwise, begin with the single product that fits your routine.
