Arrae MB-1 (Metabolic Burn) Review
Pricing and formulation last verified August 3, 2026
The short version
Arrae MB-1 assembles seven ingredients that mostly do have individual studies behind them — and then hides every dose inside a proprietary blend. At around $65 a month that's a lot to pay for a formula you can't verify against the research it cites. Independent dietitian reviews have been skeptical, and none of the mechanisms here is as direct as fibre or Akkermansia.
What the evidence supports
Several components have real individual research — Bifidobacterium lactis B420 has published work on body fat, and cissus and grains of paradise have small studies. But studies test specific doses, and a proprietary blend makes it impossible to know whether any ingredient appears at a studied amount. Cited research you can't verify against the label isn't usable evidence.

What Is Arrae MB-1 (Metabolic Burn)?
Arrae MB-1 combines seven ingredients aimed at cravings and metabolism: African mango seed extract, cissus extract (CQR-300), grains of paradise seed extract, Bifidobacterium lactis B420, green tea, chromium picolinate and vitamin B6. Several of these do have individual clinical studies behind them, and B420 in particular has published work on body fat. The problem is the proprietary blend — individual doses aren't disclosed, so there's no way to check whether any ingredient appears at a studied amount. At around $65 a month it's priced in the premium tier, and independent dietitian reviews have been notably skeptical. Arrae also sells an MB-1 45+ variant targeting menopause-related weight change.
The proprietary blend problem
MB-1 lists seven ingredients: African mango seed extract, cissus extract (CQR-300), grains of paradise seed extract, Bifidobacterium lactis B420, green tea, chromium picolinate and vitamin B6.
What it doesn't list is how much of each. That's the entire problem. Every study cited for these ingredients used a specific dose, and without disclosure you cannot tell whether MB-1 contains a research-relevant amount or a sprinkle sufficient to name it on the label.
This matters most for B420, which is the component with the strongest individual evidence. Probiotic effects are dose-dependent, and an undisclosed count is an unanswerable question.
What the individual ingredients actually have behind them
Bifidobacterium lactis B420 is the strongest of them, with published research on body fat mass in overweight adults. It's a legitimate inclusion.
Cissus quadrangularis (CQR-300) and grains of paradise both have small studies suggesting metabolic effects — grains of paradise via brown adipose tissue activation. The trials are small and short.
African mango seed extract has a thinner record than its marketing suggests. Green tea extract, chromium picolinate and vitamin B6 are common metabolism-formula inclusions with modest evidence.
The honest summary: a couple of reasonable ingredients, several filler-tier ones, and no way to check the doses on any of them.
The price is hard to defend
Around $65 a month places MB-1 in the premium tier. For comparison: Codeage delivers Akkermansia at roughly $10 a month, Supergut delivers 6 grams of fibre at around $1.50 a day, and Toniiq delivers 97% berberine for under $30.
Each of those has either a more direct mechanism, disclosed dosing, or both. MB-1 has neither, at a higher price.
Independent dietitian reviews have been consistently skeptical, which is worth weighing against the customer testimonials on the product page.
The MB-1 45+ variant
Arrae also sells MB-1 45+, positioned around menopause-related weight change and claiming to support GLP-1, oestrogen and cortisol together.
The underlying premise is legitimate: midlife weight gain in women is genuinely an endocrine event, driven by declining oestrogen shifting fat distribution and disrupting sleep. That's real physiology, not marketing.
Whether a botanical blend meaningfully addresses it is a much weaker claim. If perimenopausal weight change is your issue, a clinician who can evaluate hormone therapy will do more than a supplement — see our coverage of midlife-focused providers.
Who It's For
- People drawn to a multi-ingredient botanical approach who accept undisclosed dosing
- Buyers who want to read the label in person at GNC or Ulta first
- Anyone who has responded well to B420-containing products before
Who Should Skip It
- Anyone who wants to verify doses against the cited research
- Cost-focused buyers — better-evidenced options cost a fraction of this
- People who want the most direct mechanism rather than the broadest ingredient list
Arrae MB-1 (Metabolic Burn) — Frequently Asked Questions
What's actually in Arrae MB-1?
Seven ingredients: African mango seed, cissus (CQR-300), grains of paradise, Bifidobacterium lactis B420, green tea, chromium picolinate and vitamin B6 — all inside a proprietary blend, so individual doses aren't disclosed.
Does it actually work?
Some ingredients have individual studies, B420 most credibly. But studies test specific doses, and a proprietary blend makes it impossible to know whether MB-1 contains research-relevant amounts. Independent dietitian reviews have been skeptical.
Is it FDA approved?
No. No dietary supplement is FDA approved before sale — they're regulated as food, without pre-market approval or required efficacy evidence.
Why does the proprietary blend matter so much?
Because it makes the cited research unusable. If a study found an effect at 400 mg and you can't tell whether the capsule has 400 mg or 4 mg, the study tells you nothing about the product.
What about MB-1 45+ for menopause?
The premise is sound — midlife weight change genuinely is an endocrine event. Whether a botanical blend addresses it meaningfully is a much weaker claim. A clinician who can evaluate hormone therapy will likely do more.

| Product | Score | Price | Why consider it |
|---|---|---|---|
| Arrae MB-1 (Metabolic Burn) ⭐ | 7.3/10 | Around $65 per month | People drawn to a multi-ingredient botanical approach who accept that the doses aren't disclosed |
| Codeage GLP-1 Probiotic+ | 8.6/10 | Around $29.99 for 90 capsules (3-month supply) | Disclosed strains at roughly $10 a month |

| Lemme Reset (GLP-1 Daily) | 7.6/10 | Around $72 per month | Comparable positioning with a slightly higher review volume |
Final Verdict
Arrae MB-1 earns 7.3/10. A couple of ingredients have genuine individual research behind them, and the multi-pathway thinking isn't unreasonable.
The proprietary blend is what caps it. At around $65 a month you're paying premium pricing for a formula you cannot verify against the studies it leans on, when products with disclosed doses and more direct mechanisms cost far less.
