Nagano Lean Body Tonic contains a blend of bioactive ingredients, such as polyphenols and a small amount of caffeine, which speed up the metabolism, promoting rapid fat burning and weight loss through thermogenesis. It also increases energy levels so you can be more active and burn more calories.

The Nagano Lean Body Tonic formula also contains probiotics, which are healthy intestinal bacteria that live in the gut, killing off harmful microbes. The supplement is rich in prebiotic fiber, which feeds the probiotics in the gut. This helps them proliferate and promote a healthy microbiome and can also help with weight loss.

A study of overweight adults by Pernilla Danielsson and others, published in Scientific Reports, found that a high dose of probiotics can be beneficial for weight loss.

Fiber cleanses the colon of waste and toxins and improves digestion, promoting more regular bowel movements and relieving symptoms such as constipation and bloating. They also slow down digestion, making you feel full for longer and eat fewer calories.
