VILNIUS, Lithuania, Aug. 25, 2025 (GLOBE NEWSWIRE) — The 72-Hour Fasting Kit quickly became a favorite for its gut health benefits and weight loss support using science-backed products – but some users reported clumping issues when mixing the supplements. BurnBox listened to user feedback and upgraded the kit with a powdered mixer and adjusted supplement quantities. Here’s what’s new inside the updated box.
What Changed with BurnBox, and Why It Matters for Subscribers
The biggest update to the BurnBox fasting kit is the new powdered mixer, which was added after users reported trouble blending supplements with water alone. It helps eliminate clumps, especially in fiber and broth drinks, making each packet easier to prep and smoother to drink.
The kit now includes three distinct supplements – Electrolyte Booster, Fiber Shake, and Bone Broth.
- The Electrolyte Booster: This comes in the lime flavor and delivers calcium, magnesium, potassium, sodium, and phosphorus (~640 mg sodium, 820 mg potassium) in about 15 calories.
- Fiber Shake: The grapefruit-flavored Fiber Shake is a 30-calorie packet with 3 g psyllium husk and 1 g flaxseed powder. It helps promote fullness and supports digestive regularity during fasting.
- Bone Broth: The Bone Broth Powder contains 5 g bone broth concentrate, 3 g protein, MCT coconut oil, and minimal carbs (~30 calories) that lightly nourish without breaking ketosis.
The brand stated that its goal was to improve the practicality and convenience of fasting for both new and experienced users. These changes can help remove small daily hurdles like poor mixing or inconsistent nutrient intake.
The updated kit is now part of the August shipment. Existing subscribers receive it automatically, while new customers can access it through the quiz-based selection process.

BurnBox Fasting Feedback For The Updated Box
But does this product actually work? The BurnBox Fasting Kit has received positive feedback from a wide variety of sources. The kit maintains a 4.8 out of 5 from over 2,500 ratings. In a Burnbox feedback survey conducted in July 2025 by Trustpilot, over 70% of users are completely satisfied and reported improved energy levels and fewer cravings with the updated hydration and supplement protocol.
A user from Austin, TX, noted, “I lost 21 lbs effortlessly! The fiber shake kept hunger at bay, the bone broth stopped that sick, empty feeling, and the whole process was a breeze.” Another user from San Diego has shared her BurnBox experience and how the kit actually gave her more control, “I’ve struggled with weight issues for decades, and this fasting kit was a revelation. It’s not just about the weight loss (over 12 pounds lost in just 3 days), but also about gaining control over my hunger and eating habits. This approach has given me a newfound sense of control and optimism.”
How to Explore the Updated BurnBox
