Frequently Asked Questions

What is a postbiotic?

A postbiotic is a heat-inactivated form of a probiotic, delivering all the benefits of probiotics in a stable, highly effective form your body can easily use. Tone contains a unique plant-based postbiotic to support body composition through the microbiome.

What are the main benefits of creatine supplementation?

Creatine supplementation is known for boosting strength, improving exercise performance, and enhancing muscle recovery. It helps your muscles produce energy during high-intensity workouts, making it easier to push harder and achieve better results. Creatine can also support body composition goals by promoting muscle growth and reducing fatigue during training.

When should I take Tone?

We recommend taking Tone daily for optimal results. While it can be taken any time of day, on days when you’re working out, taking Tone before exercise may help fuel your muscles during high-intensity workouts, while taking it after can support recovery and muscle growth.

Why does Tone have sugar?

Tone contains a small amount of organic cane sugar (1g of sugar per gummy), as sugar and carbs are important for the bioavailability of creatine and its transport to muscle cells. This enhances uptake and retention, allowing you to maximize results.

Are Tone gummies safe for children?

We do not recommend Tone for individuals under the age of 18.

Are your gummies vegan/vegetarian?

Yes, Tone gummies are vegan.

What is creatine?

Creatine is a compound your body naturally makes to help fuel your muscles and brain, especially during high-energy activities. Creatine supports boosting strength, enhancing performance, and speeding up muscle recovery. Backed by thousands of clinical research studies, creatine is a safe and effective way to support your fitness goals and feel stronger.

Why did I receive my Tone in different packaging than expected?

You may receive Tone in either our original jar or our new, resealable pouch. Both are verified Arrae packaging and contain the exact same formula.

We’re in the process of updating our packaging to create a smarter, more streamlined experience. While we transition, you might see either format — but rest assured, it’s always the same product you know and trust.

Can I take MB-1 after getting off of a GLP-1 drug?

While MB-1 can help support your weight management and metabolism journey after discontinuing a GLP-1 drug, we always recommend consulting with your physician.

How is this different from GLP-1 drugs?

While medications like Ozempic and Wegovy work by mimicking the effects of GLP-1, a hormone your body produces to help regulate satiety and blood sugar, it can also slow digestion leading to uncomfortable GI side effects in some patients.

MB-1 is an all natural solution, working through multiple different pathways to target 360 metabolic health.

How is this different from other natural metabolism solutions?

We designed MB-1 to be the #1 solution for all of your metabolic health needs. Whether you’re looking to optimize for calorie burn, cravings, weight management, healthy blood glucose or cholesterol levels, MB-1 targets it all.

When can I expect to see results from MB-1?

MB-1 was designed to be taken daily and we recommend taking the product consistently for 3 months to see results. That said, you should feel the product beginning to kick in as early as month 1.

Do I need to take MB-1 daily in order to see the effects?

Yes, MB-1 was designed to be a daily use product for optimal results.

Does MB-1 contain caffeine?

MB-1 contains about half a cup of coffee in terms of its caffeine content. The caffeine is all natural, sourced from green tea for sustained energy without any jitters.

Can I take MB-1 if I am already on a blood sugar and/or cholesterol medication?

Though we are not aware of any interactions, we recommend consulting with your physician before combining any of our supplements with other medications.

Can I take this product if I am already on a weight management medication or GLP-1 drug?

Though we are not aware of any interactions, we recommend consulting with your physician before combining any of our supplements with other medications.

What is the best way to take MB-1?

We recommend taking 2 MB-1 capsules either in the morning or pre-workout. MB-1 can really be taken at any time of day but it was formulated to boost energy levels, so we don’t recommend taking it close to bedtime.

Who Is MB-1 For?

MB-1 is for anyone looking for a natural, effective solution for healthy weight management and optimizing metabolic health. We designed MB-1 to comprehensively target your metabolism, so whether you struggle with cravings, low energy levels, glucose spikes, body composition, or are simply looking to be preventative when it comes to your metabolic health, MB-1 can support you.
