Innermost Detox Booster Review (2026)

If you have ever stood in a health food aisle staring at something called a ‘detox’ powder and thought “but does this actually do anything?” - you are not alone. I get that question from clients every week. The Detox Booster is a well-formulated antioxidant blend with one meaningful limitation: no published per-ingredient doses. The word ‘detox’ has been attached to everything from green tea to charcoal lemonade, and the science behind most of it does not hold up.

So when I came across Innermost The Detox Booster, I wanted to test it properly. Not just shake it up and see how I felt, but work through every ingredient against the published research. Because when a product makes claims about "naturally detoxing and cleansing the body," that is exactly the kind of language that deserves scrutiny.

I am a registered Nutritional Therapist holding a Diploma in Nutritional Therapy from the College of Naturopathic Medicine, and a BANT member with clinical experience spanning Google DeepMind’s nutrition programme and The Wellness Clinic at Harrods. I have reviewed dozens of supplement formulations in the greens powders space, including the other products in our best greens powders guide. What follows is what I actually found.

Ten ingredients. Five grams per serving. One significant transparency gap. Innermost The Detox Booster brings a well-chosen set of actives - spirulina, chlorella, wheatgrass, matcha, turmeric, maca, camu camu, kelp, peppermint, and cocoa - all of which have legitimate research behind them. The formulation philosophy is sound. The honest limitation: Innermost does not publish the individual ingredient doses per serving, which makes it impossible to verify whether each active is present at a clinically meaningful level. That matters more than the ingredient list itself.

If you are looking for a convenient daily greens blend with a clean ingredient philosophy and a genuinely drinkable taste, The Detox Booster earns its place. But the word ‘detox’ on the label is marketing language, not a clinical description - and I will explain exactly what the product can and cannot honestly claim to do.

One note on availability: At the time of writing, The Detox Booster does not appear in Innermost’s main product range on their website (innermostglobal.com). It remains available through third-party retailers including Cult Beauty (£24.95 for 300g as of June 2026). If you are considering purchasing, check current availability before committing.

Founded in London in 2016, Innermost has built their positioning around clean-label, science-led formulation aimed at active, health-conscious consumers - the kind of buyer who reads ingredient lists and wants to understand what they are taking and why.

What sets Innermost apart from most of the greens powder category is their transparency philosophy. Their marketing consistently references the ‘why’ behind each ingredient rather than leading with ingredient counts or proprietary blends. They publish readable explanations of their formulation rationale on their website, which is a better signal of intent than a long ingredients list alone.

Their current range covers proteins, blends, boosters, and capsules. The Detox Booster was part of their booster line, designed for mixing into hot water or smoothies as a functional add-on to an existing routine, rather than a meal replacement or complete nutrition product.

The brand has a solid retail footprint - stocked at Selfridges, Cult Beauty, Urban Outfitters, and Oliver Bonas - which reflects consumer confidence in the positioning. Judge.me aggregates 4.8 out of 5 from over 1,500 reviews across their product range, though Trustpilot shows a more mixed 3.1 from a much smaller base. Both data points are worth holding in context: high volume, high satisfaction on product quality; a handful of negative experiences mostly related to delivery and customer service.

Can ten ingredients in 5g actually deliver anything meaningful? That is the right question to ask before buying this product. The Detox Booster is formulated to "support overall wellbeing, vitality, and immunity whilst naturally detoxing and cleansing the body," with each serving being 5g (one rounded teaspoon), mixed into hot water or your preferred milk.

Innermost does not publish individual ingredient quantities on the product label or website. The 5g total serving is shared across all ten ingredients, which is important context I will come back to in the dosage audit below.

This is where I need to be honest with you - and where most greens powder reviews stop short.

A 5g serving divided across ten ingredients means each active averages 500mg. That sounds reasonable in isolation. But here is the issue: several of these ingredients require specific doses to deliver the effects the research supports.

Turmeric/Curcumin: Research showing anti-inflammatory benefit typically uses 500mg to 2,000mg of curcumin daily, often alongside piperine to improve absorption. A 5g powder split ten ways is unlikely to include enough curcumin at clinical doses. Without published quantities, I cannot confirm or deny - but you should know this limitation exists.

Spirulina: Doses in studies supporting immune and antioxidant benefits typically range from 1g to 3g daily. If spirulina is the first or second ingredient by weight, it may be present at a meaningful dose. If it is further down the priority order, less likely.

Chlorella: Evidence for heavy metal binding and natural excretion support (one of the more credible ‘detox’ mechanisms studied) uses doses of 3g to 5g per day - the full serving size of this product. Again, without quantities, we cannot know.

Maca: Adaptogenic benefits in studies typically use 1.5g to 3g daily. At 500mg average, this is below effective dose unless maca is significantly weighted in the formula.

Camu camu and kelp: These are typically effective in much smaller amounts (kelp for iodine; camu camu for vitamin C), so they may be appropriately dosed even at low inclusion.

My assessment: the ingredient selection is genuinely good. Every one of these ten has legitimate research behind it. But the per-serving dose limitations are real, and I would rather tell you that clearly than let you assume a single 5g scoop is delivering clinical-level benefit across all ten actives. It almost certainly is not. What it likely is doing is providing meaningful micronutrient variety and a genuine antioxidant contribution - particularly from the spirulina, chlorella, and matcha, which are the most bioavailable actives at lower doses.

I want to address this directly, because the word on the label deserves an honest response.

Your liver and kidneys detoxify your body continuously. The liver processes 1.4 litres of blood per minute, filtering toxins, converting ammonia to urea, and conjugating compounds for excretion. Your kidneys filter approximately 180 litres of blood every day. These are not processes that need assistance from a powder.

The British Dietetic Association states clearly: "The whole idea of detox is nonsense. Unless you have a serious medical condition, your body is a well-developed system that has its own built-in ability to detoxify and remove waste."

What greens powders like this one can honestly do is provide antioxidant support - compounds that help neutralise free radicals and reduce oxidative stress, which is a genuine and well-researched area of nutrition science. Chlorella has been studied for supporting the body’s natural excretion of certain heavy metals. Spirulina has antioxidant and anti-inflammatory properties with solid research behind them.

So: does The Detox Booster ‘detox’ you? No - your body does that without it. Does it provide a meaningful antioxidant and micronutrient contribution alongside a healthy diet? Genuinely, yes - if the doses are adequate, and I have explained above why that remains an open question.

This is not a criticism of Innermost specifically - ‘detox’ is a category-wide marketing norm. But as a nutritionist, I think readers deserve that clarity.

I mixed one 5g serving into approximately 200ml of hot water each morning for 30 days, typically around 7am alongside my standard morning herbal tea. I kept notes on taste, mixability, digestion, and energy across the period.

Taste: Better than expected. The peppermint lifts the cocoa and matcha base in a way that makes the drink genuinely pleasant rather than medicinal. The earthy wheatgrass and spirulina notes are present but not dominant. Cold water dilutes the flavour significantly - I would consistently recommend hot water or your preferred plant milk.

Mixability: The 5g serving dissolves readily in hot water with a simple stir. No clumping, no residue at the bottom. Better than the majority of greens powders I have tested in this category.

Digestion: I did not experience any digestive discomfort over the 30 days. The peppermint inclusion likely contributes here - it is a well-documented digestive support herb and it seems to work in this context. No bloating, no change in GI pattern.

Energy and focus: I noticed a steady alertness on most mornings - the kind I would attribute to a consistent matcha habit rather than an acute energy effect. Whether this was the matcha, the maca, the cocoa flavanols, or simply the ritual of a warm morning drink, I cannot isolate. That is an honest limitation of self-reported supplement testing: single-blind consumer experience is not clinical data.

Weeks three and four: I genuinely looked forward to the drink each morning, which for a supplement is a better outcome than most. If the routine gets you to drink it daily, the cumulative antioxidant contribution adds up.

At £24.95 for 300g (60 servings at 5g each), The Detox Booster comes in at approximately 42p per serving (as of June 2026, Cult Beauty). That is competitive positioning.

At 42p per serving, Innermost The Detox Booster sits at the budget end of the premium greens category. The trade-off versus higher-priced products is dose transparency and ingredient count: AG1 review (buy on Amazon) publishes a full nutritional breakdown of 83 ingredients with quantities, which allows proper dosage verification. Huel Daily Greens review (buy on Amazon) similarly provides complete labelling. Innermost does not, which limits what you can verify for the price you pay.

If budget is a primary constraint and you want a daily antioxidant-rich greens habit, the price-to-ingredient-quality ratio here is reasonable. If you want dose transparency and verifiable clinical coverage, the higher-priced options deliver that more clearly.

Skip this if:

The honest framing: this is a lifestyle-grade greens powder with a genuinely clean formulation and a pleasant sensory experience. It is not a therapeutic-grade supplement. That distinction matters, and you should make your choice with that in mind.

At the time of writing (June 2026), The Detox Booster is not listed on innermostglobal.com’s main product range. It remains available through third-party UK retailers.

Retailers:

If you cannot find it in stock, Innermost’s current booster range includes The Energy Booster, The Define Booster, and The Power Booster. For a comparable greens blend with published dosing, see our Huel Daily Greens review (buy on Amazon) or the Verve V80 review.

At 42p per serving, The Detox Booster earns its place - with one caveat you need to understand first. The ingredient selection is thoughtful and research-grounded, and it gives you a convenient daily antioxidant and micronutrient contribution in a genuinely pleasant, mixable format. The price per serving is fair.

The limitation I cannot look past is dose transparency. Without published quantities, you are trusting the formulation philosophy rather than verifiable efficacy. That is a reasonable position for a lifestyle supplement at 42p per serving. It is not a reasonable position if you are trying to meet specific therapeutic goals.

And on the ‘detox’ question: the name oversells what this product does. Your liver and kidneys handle detoxification without any supplement’s help. What Innermost has made is a quality antioxidant and adaptogen blend - which is a legitimate and useful thing, just not quite what the label implies.

If The Detox Booster is in stock and within your budget, it earns a genuine recommendation as a daily routine supplement. Start with one serving in hot water every morning for four weeks and notice whether the habit itself, not just the ingredients, changes how your days feel.

Overall score: 7.5 / 10
