Key Benefits

  • Improves metabolism to help you burn more calories.
  • Curbs cravings and regulates appetite.
  • Regulates glucose and cholesterol levels.
  • Promotes healthy gut function.

This all-natural supplement is designed to supercharge your metabolism and support optimal health and vitality. Backed by 15 clinical trials across its seven potent ingredients, MB-1 addresses the root cause of metabolic dysfunction by activating AMPK and key metabolic enzymes, helping you maintain a healthy body composition. Its unique blend increases your resting metabolic rate, so you burn more calories even at rest, while also targeting visceral fat. MB-1 optimises your body’s ability to convert food into fuel and supports ATP production, delivering steady energy without the jitters. It also regulates hunger hormones to curb cravings effectively.

Arrae users can experience up to a 20% reduction in body fat, a 31% drop in blood sugar levels, and a 44% decrease in total cholesterol within just 90 days.

*Based on third-party clinical testing.

What’s inside?

African Mango Seed (IGOB131®): Reduces fat cells, improves insulin sensitivity, and controls appetite to help manage your waistline.

Cissus Extract (CQR-300®): Blocks fat and carb absorption, ensuring you burn calories instead of storing them.

Grains of Paradise: Activates brown adipose tissue (BAT), boosting calorie-burning potential and raising resting metabolic rate.

Bifidobacterium Lactis B420: Supports gut health, improves digestion, and controls cravings for better weight management.

Green Tea Extract: Acts as a prebiotic, balancing metabolism and providing steady, sustained energy.

Vitamin B6 (Pyridoxal 5-Phosphate): Crucial for protein metabolism and balancing blood sugar, helping maintain steady energy.

Chromium Picolinate: Enhances insulin sensitivity, regulates blood sugar, and activates AMPK for optimal metabolic function.

Whether your BMI is above or below 25, MB-1 is crafted to optimise body composition, boost energy, curb cravings, and improve metabolic markers like blood sugar and cholesterol. It's also ideal if you're dealing with tiredness, fatigue, weight management challenges, and want to enhance your exercise performance. Take control of your metabolism and achieve optimal health with MB-1.

Arrae MB-1 combines nearly 2 years of research with 15 clinical trials to optimise your metabolic health in just 3 months. This revolutionary formula includes clinically-studied herbs, a targeted probiotic, and essential nutrients that work together to boost your metabolism by up to 500%. It activates key enzymes for energy and weight management while regulating hunger hormones to curb cravings, unlocking your full metabolic potential.

When Siff and Nish started Arrae, their main objective was to create a natural, high-quality and functional supplement made beautiful.

Arrae believes that when it comes to personal goals and peak health, you don't have to make a choice, you can have both.
