What is Thin 30 Probiotic?

Thin 30 Probiotic is a probiotic supplement that is formulated to boost digestion and reduce fatty acid absorption. Its weight management blend may improve metabolism and fat-burning through its natural ingredients. According to a clinical study by the company, 100 patients on Thin 30 lost an average of 30 lbs in 90 days which is quite impressive.

Green tea in Thin 30 is caffeine-free, meaning it is suitable for users with caffeine sensitivity. It contains bioactive substances such as EGCG known to boost metabolism which in turn supports fat burning. Antioxidants present in green tea protect the cells from free radicals that cause oxidative stress. Oxidative stress increases the risk of developing various chronic diseases.

Probiotics are living microorganisms present in the gastrointestinal tract. These organisms maintain a healthy digestive system and may cause weight loss. Probiotics present in this formula include; Lactobacillus acidophilus, Lactobacillus gasseri, Lactobacillus plantarum, Lactobacillus rhamnosus, Bifidobacterium lactis, and Bifodobacterium infantis[1].

Thin 30 Probiotic also contains prebiotics from chicory root, Jerusalem artichoke, and acacia which support the microbiome population further promoting digestive health. Lastly, this product contains digestive enzymes that catalyze the breakdown of food including fats.

How Does Thin 30 Probiotic Work?

Thin 30 Probiotic works through its ingredients to improve digestive health and weight loss. It contains five main ingredients in its formula which include the probiotic blend, prebiotic blend, apple cider vinegar, and Greenselect phytosome as well as Capsimax cayenne pepper extract.

While probiotics are widely associated with digestive health, these microorganisms can also cause weight loss. Two types of good bacteria affect body weight, they are bacteroidetes and firmicutes. Studies indicate that obese subjects have a significantly higher level of firmicutes and a lower level of Bacteroides compared to normal-weight individuals[2].

Prebiotics are fiber and as such help improve satiety. Since they fill you up faster, you will be inclined to take less caloric food. Additionally, prebiotics have an impact on nutrient absorption and are associated with reduced fat absorption. Other mechanisms of action on metabolic health include changes in intestinal viscosity, rate of passage, production of short-chain fatty acids, and production of gut hormones[3].

Green tea on its part is rich in antioxidant content. Its most notable flavonoid is catechin is associated with increased metabolism. Catechin works to inhibit enzymes catechol O-methyl-transferase and phosphodiesterase thus improving fat oxidation and thermogenesis[4].

As for organic apple cider vinegar, while it may not necessarily cause weight loss, it has many health benefits such as lowering blood sugar levels[5]. Cayenne pepper on its part is associated with improved thermogenesis and reduced appetite[6].

Thin 30 Probiotic Ingredients – Are they Safe?

Lactobacillus Acidophilus

Lactobacillus acidophilus is categorized as a probiotic or good bacteria found in the human mouth, gut, vagina, and in certain foods. As discussed in our Nuzena Probiotic Gut Boost 40+ Review, it plays a vital role in maintaining healthy vaginal flora, reducing infection risks, and supporting mental health.

In a review study in the Nutrients journal, Lactobacillus strains were found to decrease body weight, waist circumference, and fat percentage[7].

According to Ruairi Robertson, PhD, Lactobacillus acidophilus has many benefits such as may reduce cholesterol, may reduce and prevent diarrhea, may improve IBS (irritable bowel syndrome) symptoms, and may treat and prevent vaginal infections. As for weight loss, he states that “the evidence on L .acidophilus alone is unclear.”

Bifidobacterium Lactis

Bifidobacterium lactis is a probiotic known to be resistant to the harsh acidic environment in the stomach. In a 12-week comparative trial published in the Bioscience of Microbiota, Food, and Health, B. lactis was found to be effective in reducing abdominal visceral fat, a key indicator of metabolic disorders[8].

Lotta K. Stenman, Global Health and Nutrition Science, DuPont Nutrition & Health, Finland, and team conducted clinical trials that Bifidobacterium lactis with or without dietary fiber controls body fat mass[9].

Greenselect® Phytosome

This is a proprietary, caffeine-free extract retrieved from green tea. A Cochrane systematic review published in the Canadian Pharmacists Journal concluded that green tea preparations have the ability to cause weight loss. Subjects in the green tea group lost an average of 0.2 to 3.5 kg more than subjects in the control group[10].

According to Teresa Fung, a dietitian and co-chair of the Department of Nutrition at Simmons University in Boston, “green is special because it contains strong antioxidants called polyphenols,” and while they help neutralize free radicals, they do not cause significant weight loss in adults.

Capsimax® Cayenne Pepper Extract

Capsimax is a patented cayenne pepper extract claimed to support weight loss and management. Capsaicin is the main ingredient in chili peppers and is associated with weight loss. While in mice capsaicin has been found to prevent accumulation of fat deposits, in humans the results were not mimicked. A review of studies in the Pharmaceuticals journal concluded that there are no significant differences in BMI between chili-eaters and non-eaters[11].

Researchers Jose E. Galgani and Eric Ravussin in an article published in the American Journal of Clinical Nutrition found that dihydrocapsiate, a capsinoid found in cayenne pepper has thermogenic properties. People who took this supplement experienced an increase in their metabolic rates[12].

These microorganisms work together to fight against harmful bacteria which may cause diseases. Prebiotics in the supplement are used as food by the bacteria.
