Probiotic Lean by Celarity

Specific Probiotic Strains to Support Weight Loss

Probiotics, often referred to as "good bacteria," have garnered attention for their potential role in weight management. Research suggests that certain strains of probiotics may influence weight loss by modulating gut bacteria composition, which can impact metabolism and energy regulation. Additionally, probiotics may help reduce inflammation and improve gut barrier function, potentially reducing the risk of obesity-related complications.

What are Probiotics?

Probiotics are bacteria that line your gut and your entire body to keep you healthy. Probiotics play many roles in the body, from vitamin production to immune system regulation. Your body hosts nearly 2,000 types of bacteria that first seeded in the womb. Then through natural childbirth, you received another healthy dose of bacteria that solidifies your microbiome as you enter into the world. Your microbiome consists of over 100 trillion bacterial cells and 33 million genes that live in and on us. Taking probiotics on a daily basis strengthens our gut and our whole body.

How does Probiotic Lean Help With Weight Loss?

Bifidobacterium animalis subsp lactis B420 is a specific strain of probiotic that has gained attention for its potential benefits for gut health and weight management. Research suggests that B420 may help support a healthy gut microbiota by promoting the growth of beneficial bacteria and inhibiting harmful ones. Furthermore, B420 has been shown to help regulate appetite and reduce calorie intake, potentially contributing to weight loss efforts. By modulating gut microbiota composition and improving gut barrier function, B420 may also help alleviate symptoms of gastrointestinal disorders and promote overall digestive health.

Why Most Probiotics Don't Work

When it comes to probiotics you get what you pay for. If you buy a cheap one, you’ll likely get one that doesn’t work.A common challenge with probiotics is maintaining the stability of the organisms as they are distributed to the patient and then stored on the shelf. Many probiotics are dead before you even take them. Furthermore, as you consume the probiotic it is important to maintain the stability of the organism as it travels through the stomach and into the digestive tract. You want the probiotic to make it to the digestive tract alive.
