Arrae MB-1 is a metabolic capsule built on Grains of Paradise, Cissus extract and Bifidobacterium lactis B420, marketed with up-to percentages drawn from ingredient studies.
Overview
Arrae is a direct-to-consumer supplement brand whose MB-1 Metabolic Burn is its weight management product, sold at around $65 a month and also stocked at GNC and Amazon. A separate MB-1 45+ formulation targets perimenopause and menopause, claiming up to 18 percent reduction in body fat.
The ingredient selection is genuinely better than average. Grains of Paradise extract, from a relative of ginger, has published research on thermogenesis and brown adipose tissue activation. Cissus quadrangularis has a small body composition literature. Bifidobacterium lactis B420 is the most interesting: it has published human trials reporting reductions in body fat mass and waist circumference, which is more than most probiotic strains can claim. Arrae names all three rather than concealing them in a proprietary blend.
The marketing is where care is needed. The product page advertises up to 12 percent reduction in body weight, up to 31 percent decrease in blood glucose levels and up to 21 percent on further markers. These are up-to figures drawn from studies on individual ingredients, and they describe the best result in the best study rather than what a buyer should expect. MB-1 also contains caffeine from green tea extract, which is a poor combination for someone already experiencing the nausea and disturbed sleep common on GLP-1 medication. Trustpilot carries one-star reviews describing nausea from the 45+ version and difficulty reporting it to the company.

What Is Actually in It
- Grains of Paradise extract, with published thermogenic research
- Cissus quadrangularis extract
- Bifidobacterium lactis B420, with human trials on body fat
- Caffeine from green tea extract
- A separate MB-1 45+ formulation for perimenopause and menopause

Supplement or Medication?
A dietary supplement. Grains of Paradise acts on thermogenesis, B420 on the microbiome. Neither is a GLP-1 receptor agonist, and the product is a general metabolic supplement rather than a GLP-1 specific one.
How You Buy It
Buy at GNC, Amazon or direct
Retail availability avoids the subscription.
Check the caffeine content
Green tea extract provides caffeine, which suits some people badly.
Consider the 45+ version if relevant
A separate formulation targets perimenopause and menopause.
Read the percentages carefully
Up-to figures describe ingredient studies, not expected outcomes.
Who It Is Sold To
- Adults wanting a metabolic supplement with named ingredients
- No consultation or clinical assessment involved
- The caffeine content is a poor fit if you have nausea or poor sleep
- Not appropriate as a substitute for prescribed obesity treatment
- Speak to a clinician first if you take glucose-lowering medication
- Caffeine sensitivity is worth checking before buying
Clinical Oversight and Evidence
Clinical Oversight
None. This is a direct-to-consumer supplement with no clinical involvement. The caffeine content matters if you are on a GLP-1, since nausea and sleep disturbance are already common.
Evidence
Better than average at the ingredient level, absent at the product level. Grains of Paradise has published thermogenic research, Cissus a small body composition literature, and Bifidobacterium lactis B420 human trials on body fat mass and waist circumference. The advertised percentages are the highest results from those individual studies rather than findings about the finished formula, which has not been trialled.

Frequently Asked Questions
What is in Arrae MB-1?

That figure is an up-to claim drawn from studies on individual ingredients, describing the best result in the best study rather than what the finished product does. No trial exists on the formula itself.
Does it contain caffeine?
Yes, from green tea extract. That is worth knowing if you are on a GLP-1, since nausea and sleep disturbance are already common side effects.
What is Bifidobacterium lactis B420?
A probiotic strain with published human trials reporting reductions in body fat mass and waist circumference, which is more than most probiotic strains can claim. It is the best-supported ingredient in the formula.
What is MB-1 45+?
