Howaru® Shape B420: A Powerful Probiotic for Gut Health and Weight Management

May 17, 2023 | Supplements and Nutrition

Probiotics have gained significant attention in recent years for their numerous health benefits, particularly in supporting gut health and the immune system. One specific probiotic strain, Bifidobacterium animalis ssp. lactis B420, has demonstrated remarkable effects on body fat and weight loss, in addition to promoting overall gut health. In this article, we will delve into the details of this powerful probiotic and the science behind its impact on gut health and weight management.

What is Howaru Shape Bifidobacterium animalis ssp. lactis B420?

Bifidobacterium animalis ssp. lactis B420 is a probiotic strain that belongs to the Bifidobacterium genus, which is a group of beneficial bacteria commonly found in the human gastrointestinal tract. These bacteria are essential for maintaining a balanced gut microbiota and play a crucial role in overall health. B420 is a patented probiotic strain marketed under the brand name Howaru® Shape and has been the subject of extensive research for its potential health benefits.

Gut Health and B420

A healthy gut is essential for overall well-being, as it not only aids in digestion but also plays a vital role in the immune system. Imbalances in gut microbiota can lead to various health issues, including gastrointestinal disorders, weakened immune function, and even mental health problems.

Bifidobacterium animalis ssp. lactis B420 has been shown to support gut health by improving the balance of the gut microbiota. It does this by increasing the population of beneficial bacteria and inhibiting the growth of harmful bacteria, thereby promoting a healthy gut environment. Additionally, B420 helps strengthen the intestinal barrier, reducing the likelihood of harmful substances or bacteria entering the bloodstream.

Weight Management and B420

Obesity is a major health concern worldwide, and an increasing body of research suggests that the gut microbiota may play a crucial role in weight management. Bifidobacterium animalis ssp. lactis B420 has been found to positively influence body fat and weight loss, making it a potential ally in the fight against obesity.

A randomized, double-blind, placebo-controlled clinical trial conducted by Stenman et al. (2016) investigated the effects of B420 on body fat mass and other obesity-related parameters in 225 healthy adults. Participants were given either a daily dose of B420 or a placebo for six months. The results demonstrated that the B420 group experienced a significant reduction in body fat mass compared to the placebo group. Additionally, the B420 group showed improvements in waist circumference and overall body composition.

Another study conducted by Ouwehand et al. (2009) examined the effects of B420 on weight gain and body composition in a high-fat diet-induced animal model of obesity. The results indicated that B420 supplementation significantly reduced weight gain, fat mass, and abdominal fat accumulation, suggesting that this probiotic strain may be beneficial in preventing obesity.

Potential Mechanisms of Action

While the exact mechanisms by which Bifidobacterium animalis ssp. lactis B420 promotes weight loss and gut health are still being explored, some potential pathways have been proposed:

  1. Modulation of gut microbiota: B420 may promote a balanced gut microbiota by increasing beneficial bacteria and reducing harmful bacteria, ultimately leading to improved gut health and weight management.
  2. Regulation of inflammation: Chronic low-grade inflammation is associated with obesity and related metabolic disorders. B420 may help regulate inflammation by modulating the production of inflammatory markers, contributing to better weight management and overall health.
  3. Enhancement of gut barrier function: B420 may improve the integrity of the intestinal barrier, preventing harmful substances and bacteria from entering the bloodstream and contributing to inflammation and weight gain.
  4. Appetite regulation: Research suggests that B420 may influence appetite-regulating hormones, such as leptin and ghrelin, potentially leading to reduced caloric intake and weight loss.
  5. Modulation of lipid metabolism: B420 may impact lipid metabolism, potentially reducing fat storage and promoting weight loss.

Selecting a Quality Howaru Shape B420 Supplement

When choosing a probiotic supplement containing Bifidobacterium animalis ssp. lactis B420, consider the following factors to ensure a high-quality and effective product:

  1. Brand reputation: Look for a reputable brand with a history of producing high-quality probiotics.
  2. Research-backed strain: Choose a supplement that contains the patented B420 strain, as this is the specific strain that has been extensively researched for its weight management and gut health benefits.
  3. Guaranteed potency: Opt for a supplement that guarantees a specific amount of live bacteria (measured in colony-forming units, or CFUs) at the time of expiration.
  4. Storage and stability: Some probiotics require refrigeration to maintain their potency. Make sure to follow the storage instructions on the product label to ensure maximum effectiveness.
