About FNX Rebalance

FNX Fit is a sports supplement company with the goal of helping athletes and fitness enthusiasts improve endurance, strength, and recovery. FNX Rebalance is the secret ingredient to support overall health and wellness. 

This product includes a variety of greens that are known for their health benefits: wheat, oat, kamut, alfalfa, and barley grasses that are rich in anti-inflammatory properties. Also included is a blend of probiotics and digestive enzymes to improve gut health and integrity. Trace minerals are also added to the blend, along with electrolytes, to speed up recovery.

FNX Rebalance Benefits

Gut Health

With an array of digestive enzymes and a rich probiotic blend, this greens supplement contains the right essentials to improve gut health. Digestive enzymes help break food down in the gut to prevent GI distress such as bloating, gas, or diarrhea. The probiotics improve the gut microbiome, leading to better gut health.

Performance Enhancer

FNX Fit focuses on an active population, so including trace minerals and electrolytes is a must-have for athletes. This product contains trace minerals, electrolytes, and a potent greens blend designed to fight inflammation and increase the speed of recovery after hard workouts. Better recovery = better results!

Reduced Inflammation

The greens play a vital role to reduce oxidative stress in the body. Oxidative stress is basically the buildup of free radicals in the body which can increase the risk of developing chronic disease and inflammation. In general, leafy greens contain phytonutrients specific for combating inflammation and balancing out these free radicals.

Liver Detox

Although the liver detoxes on its own, a healthful diet can help the liver function at its best. Your liver is basically the filter in your body and can often become overworked if you are constantly feeding your body toxins. Consuming greens that are found in this product can aid in lowering inflammation and improving the liver’s ability to work in the body.

Immune Support

The high-powered antioxidant blends and trace minerals strengthen the immune cells and prevent the onset of illness. 70% of your immune system is actually in your gut, and with the addition of digestive enzymes, probiotics, and greens, a healthy gut can improve your immune system.

Raw & Organic Greens Juice Blend (barley, alfalfa, wheat, kamut, and oat grass juice powder)

While green powders are a great way to get added antioxidants, they are not a great source of fiber. When eating vegetables in their whole form you get both antioxidants and fiber which are overall beneficial for health. However, for those who are struggling with oxidative stress or looking to add more antioxidants to their diet, powdered greens can be a great addition.

FNX Rebalance Ingredients

Digestion & Gut Health Blend (bacillus subtilis HU58, bacillus coagulans HC)

There are two specific probiotics added to this blend. Bacillus subtilis HU58 has been shown to improve gut health primarily through improving the gut barrier function. Bacillus coagulans HC is specific to improving constipation, diarrhea, and overall symptoms of irritable bowel syndrome (IBS). All probiotics have a specific job to do, and with the combination of these two products, there is a range of gut health benefits. 

Digestive Enzyme Blend (17 different enzymes)

The diverse amount of digestive enzymes in this supplement is helpful for one thing: breaking food down. This helps to take work away from the gut, preventing unwanted symptoms such as bloating, gas, constipation, or diarrhea. There are thousands of different enzymes in the body, and this product contains the important 17 to help break food down and improve gut function.

Trace Minerals

Important for a multitude of health benefits, trace minerals are essential to the human body in very small amounts. The essential trace minerals needed in the body include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium. 

Trace minerals are helpful for brain, hormone, muscle, blood, and metabolic health. If you consume a well-rounded diet you will more than likely meet the needs for these essential trace minerals. Because trace minerals are needed in smaller amounts there is a risk of toxicity. Check your other supplements to ensure you are not overconsuming these trace minerals.


FNX markets primarily to an active and athletic clientele. Therefore the use of electrolytes is very important. The important electrolytes needed to improve performance and longevity during exercise include sodium, potassium, magnesium, and chloride.

Adding in an extra dose of electrolytes can help active people ensure they are replacing what they deplete during exercise. Consuming adequate amounts of electrolytes can also help with brain function, reducing muscle cramps, and balancing hormones.


The product uses four different additives to improve the taste and longevity of the product: citric acid, malic acid, natural flavor, and sucralose. The total sugar content of the product is 0 grams, which means these flavors are in small amounts and add a sweet taste while also helping the greens powder have a longer shelf life. 

Does FNX Rebalance Super Greens Work?

This product is likely to be effective. Many greens powders are packed with the right antioxidants to fight off inflammation and chronic disease, as well as improve overall health and wellness. The added benefits of trace minerals, digestive enzymes, and probiotics provide benefits for gut health, energy, and metabolic balance.

On the contrary, this product does not replace the consumption of greens. The main factor missing from many greens powders is fiber, which is essential to help good bacteria thrive in the gut, lower cholesterol, balance blood sugar, and improve metabolic health. 

This supplement can be helpful if you need to add more antioxidants to your diet. Eating whole green veggies, however, gives you the best outcome due to the fiber, vitamin, mineral, and antioxidant content.

Claims vs. Reality

FNX Rebalance claims it improves immunity, gut health, energy, and liver detoxification. There is no evidence of any scientific studies on this specific product, however, some studies do suggest the use of antioxidant-rich powders can help improve these health outcomes.

Liver detox is a controversial claim, and there is no clinical evidence that any product can detoxify your liver. The liver naturally detoxes itself. The job of the liver in the body is to filter blood. It metabolizes drugs, alcohol, or other foreign subjects including supplements, and helps to balance the body. The claim “liver detox” is not clinically backed, however, the liver may benefit from the added antioxidants in this product to reduce inflammation.

How Does FNX Rebalance Compare?

FNX Rebalance is no doubt a great, well-rated product. The cost of this product is a bit higher than its competitors, which is around $20-$40. FNX Rebalance Super Greens is priced at $58.99 for a one-time purchase or a subscription service of $38.49 per month. The argument can be made that this product contains the added benefit of gut health, whereas most greens powders contain just the greens. The price is supported by its additional benefits.

Who is FNX Rebalance Best For?

Greens powders overall benefit those who have inflammation, however, more research is leaning towards the benefit of greens for overall health. Oxidative stress and inflammation can occur when the body is under mental or physical stress. This high oxidation in the body can increase the risk of developing chronic diseases, cancer, or inflammatory issues. By consuming more antioxidants, you can balance out this high oxidation and improve health outcomes.

For active individuals, the body is under more physical stress which can lead to oxidation or inflammation. This product can help active individuals reduce soreness, improve health, and reach health and fitness goals.

Is FNX Rebalance Safe?

Some people may be sensitive to certain probiotics, including the two listed in this product. Due to the high vitamin K content from greens powders, those who are taking blood thinners should talk to their doctor before taking this product. 

No supplements are regulated by the Food and Drug Administration, which means supplements may not provide accurate information on their label. Some companies will have their product third-party tested. Based on review, the FNX Fit products do not appear to be third-party tested and therefore may contain additives not listed on their label. 

One independent study done by consumer labs found of 13 greens powders tested, 4 were contaminated with lead. If the product is not third-party tested that does not mean it is contaminated, and there have been no reports of contamination for FNX Fit products. However, knowing the potential safety of a product is always beneficial for the consumer.
