Who is the Manufacturer?

The manufacturer of Nagano Lean Body Tonic is a company called Claro Media Inc. located in Toronto, Canada. They offer a line of health and wellness products and also market popular wellness and fitness brands.

How Does It Work?

Nagano Lean Body Tonic focuses on the strong connection between gut health and weight loss. A balanced, healthy microbiome plays a key role in appetite and weight loss in addition to digestive health.

Research scientist Christian Diener, Ph. D. explains the link between gut health and weight loss: “Your gut microbiome can help or cause resistance to weight loss and this opens up the possibility to try to alter the gut microbiome to impact weight loss [1].

Nagano Lean Body Tonic has several key probiotic strains. As we said in our review of LeanBiome, these are healthy bacteria that live along the intestinal walls destroying harmful microbes and balancing the microbiome. They improve digestion, and there’s evidence that probiotics help promote weight loss.

A research review published in Nutrients by Kiran Mazloom examined the research showing the benefits of probiotics in the prevention of obesity [2].

The supplement is rich in prebiotic fiber that feeds the probiotics in the gut so they can proliferate. This enhances overall digestion, promoting healthy bowel movements and relieving issues like gas and bloating. In addition, fiber slows digestion to keep you feeling full, so you take in fewer calories daily.

A large-scale literature review published in Critical Reviews in Food Science and Nutrition by Isabella Skye Waddell showed the advantages of dietary fiber in managing obesity and preventing some chronic conditions [3].

Nagano Lean Body Tonic contains bioactive organics that increase the synthesis of important brain neurotransmitters like GABA, dopamine, and serotonin. This can boost mood, lower anxiety and stress-based eating, and sharpen cognitive functioning. In addition, as we said in our review of BioVanish, some of these chemicals help suppress appetite.

Nagano Lean Body Tonic is also high in anti-inflammatory agents and antioxidants which offer general health benefits like decreasing body-wide swelling. Antioxidants kill free radicals to lower harmful levels of oxidative stress, which promotes a strong immune system.

What Are the Key Ingredients?

These are some of the primary active ingredients in Nagano Lean Body Tonic:.

Green Tea

This nutrient-rich tea has polyphenols like ECGC which speed up the metabolism, promoting fat-burning and weight loss as well as strengthening the immune system. They also contain some of the stimulant caffeine, for heightened energy levels, exercise performance, and mental focus.

A review by Ying Lin, et al published in Phytotherapy Research explored the research showing the anti-obesity benefits of green tea [4].

Bitter Melon

This is an edible gourd rich in nutrients like Vitamin sA and C and fiber. It helps promote healthy digestion and may curb appetite and cravings for weight loss over time. In addition, bitter melon helps regulate cholesterol and blood sugar levels.

A review published in the Journal of Lipids by Md Ashraful Alam, et al explored the research on the benefits of bitter melon in preventing obesity and metabolic syndrome [5].

Ashwagandha Root

This herb contains potent antioxidants that help increase the metabolism, for rapid fat-burning and weight loss. It also improves exercise performance, boosts energy levels, and builds muscle mass and strength.

An 8-week study of adults with chronic stress published in Natural Medicine Journal by
Tori Hudson, ND found that supplementation with ashwagandha decreased stress, body weight, BMI, and cravings[6].

Taste and Aroma

Nagano Lean Body Tonic has a tangy, delicious flavor and aroma that blends fruits, ginger, apple, and other tastes and scents that make it a pleasure to drink daily.

Some users say they now drink Nagano Tonic every morning instead of coffee, and besides melting off the pounds it also gives them the energy, mental focus, and stamina to get through the day with ease.
