Spacegoods review: Rainbow Dust ingredients, caffeine, and US price

Spacegoods is a British functional beverage company founded in 2021. Its flagship Rainbow Dust combines coffee, functional mushroom extracts, ashwagandha, maca, vitamin B5, and flavor ingredients in a scoopable powder. The brand also offers decaf and flavor variants, matcha, evening and electrolyte powders, canned oat mushroom lattes, and subscription plans.

Spacegoods maintains a dedicated US storefront and publishes direct American shipping terms. This makes access clearer than with many European mushroom brands, although orders are fulfilled internationally rather than from a domestic US warehouse.

What does Spacegoods sell?

The current lineup includes:

• Rainbow Dust in coffee, chocolate, caramel, hazelnut, cinnamon, and decaf-related options
• Matcha Dust, Astro Dust, Hydro Dust and Glow Dust
• Canned Oat Mushroom Lattes, sachets and sample packs
• Trial packs, starter kits, and multi-month bundles
• Flexible subscriptions with recurring delivery

Formulas can differ by flavor and caffeine status. Customers should not transfer the Coffee version's ingredients or active amounts to every Rainbow Dust variant without checking its own nutrition panel.

Rainbow Dust active ingredients

The US product page lists 1,000 mg lion's mane fruiting-body extract, 1,000 mg cordyceps fruiting-body extract, 1,000 mg 12:1 chaga fruiting-body extract, 300 mg KSM-66 ashwagandha, 250 mg maca root, 6 mg vitamin B5, and natural caffeine from coffee.

The stated caffeine range is 80 to 120 mg per serving, comparable to many coffee drinks. That range matters: Rainbow Dust is not a low-caffeine product for every user, and the absence of an afternoon crash cannot be guaranteed. Decaf versions may still contain a small residual amount and require their own label review.

Testing and formula evaluation

Spacegoods advertises third-party laboratory testing and provides more extract detail than many lifestyle blends. A current batch certificate should still identify the product, flavor, date, laboratory, and limits for contaminants and active markers.

• Confirm beta-glucans for each mushroom extract.
• Check caffeine for the purchased flavor and batch.
• Review heavy metals, microbes, pesticides, and residual solvents.
• Inspect allergens, sweeteners, natural flavors, and full nutrition facts.

The listed milligrams improve transparency but do not guarantee enhanced cognition, immunity, endurance, mood, or stress relief. Research on individual extracts cannot establish the effect of the complete flavored beverage.

Caffeine and medical precautions

Users should count Rainbow Dust alongside coffee, tea, energy drinks, and pre-workout formulas. Caffeine can affect sleep, anxiety, heart rhythm, blood pressure, pregnancy limits, and medication response. KSM-66 ashwagandha can be unsuitable with thyroid, autoimmune, liver, pregnancy, or sedative contexts.

Chaga may matter for anticoagulant use or kidney-stone risk, while mushrooms can cause allergy or digestive effects. The product is not a treatment for attention disorders, anxiety, fatigue, depression, immune disease, or sleep problems.

Spacegoods US price and promo code

The dedicated US page currently displays a $68.00 one-time one-month purchase, with the flexible plan at $41.00, while subscription messaging and checkout panels may show lower effective prices. Code LIONSMANE45665 may provide 20% off an eligible one-time purchase, producing an estimated $54.40 price before shipping and tax.

Spacegoods advertises its subscription as 20% off the one-time price with free express delivery, alongside bundles and introductory offers. These deals may not combine with affiliate codes. Check the renewal amount, frequency, free gifts, cancellation procedure, and price after any first shipment.

US shipping and guarantee

Spacegoods ships American orders by DHL International Express in an estimated three to four business days. The listed cost is $18, with free shipping for subscriptions and orders over $75. International and EU orders are fulfilled from a Netherlands center, while UK orders use a British warehouse.

The store advertises a 60-day money-back guarantee. Customers should read current eligibility, product-use limits, refund exclusions, and return destination before purchase, especially because international return postage can materially affect value. Fruit-body labeling is helpful, yet extraction strength and beta-glucan assays are still needed to compare these doses with competing products or published studies. Customers should confirm whether free subscription shipping continues after the introductory order and whether cancellation must occur before a specific renewal date. Larger orders improve shipping value, but they also increase commitment before a customer knows whether the flavor and stimulant level suit them.

Our verdict

Spacegoods stands out for a dedicated US store, clear caffeine range, named KSM-66 ashwagandha, fruiting-body descriptions, direct American shipping, and flavor variety. The drawbacks are premium one-time pricing, international fulfillment, aggressive outcome language, and promotion complexity. Rainbow Dust is best compared as a caffeinated multi-ingredient drink, not as a pure mushroom supplement or a guaranteed jitter-free replacement for coffee.
