Metabolic Flora: Reviewing Simple Promise Probiotic Digestion Aid

Metabolic Flora by Simple Promise is a probiotic supplement that contains Morinaga (Bifidobacterium Breve B3) to help support healthy weight loss, digestive health function and boost energy.

Full Disclosure

Metabolic Flora is a nutritional supplement meant to help promote better digestive health and weight loss. Like many supplements on the market today, Metabolic Flora claims to maximize the function of the metabolism. As the bodily function that regulates weight loss, improvements to the metabolism can seriously maximize the effectiveness of any diet or exercise regimen.

By taking one capsule of Metabolic Flora daily, you can purportedly support healthy weight management, metabolic function, and overall digestive health. This is a tall order; several benefits are associated with the use of this single dietary supplement.

But metabolic supplements are a dime a dozen in this expansive industry. It can be hard to find a dietary supplement that provides the benefits consumers need. Some formulas contain useless ingredients, while others might be downright counterproductive to the weight loss process.

Is Metabolic Flora worth the price? How does Metabolic Flora work? What’s inside the formula? Find out everything you need to know about this supplement today in our comprehensive review of Metabolic Flora.


What is Metabolic Flora?

Metabolic Flora is a nutritional supplement that uses green tea extract, caffeine, and probiotic bacteria to support digestive health. The ingredient list is relatively short, and we'll cover it below in more detail.

You take one to two capsules of Metabolic Flora per day, and the supplement supports various health benefits.

Metabolic Flora is made by a Washington-based supplement company named Simple Promise. That company claims to ‘Follow the Science,” offering multiple unique dietary supplements backed by genuine scientific evidence. Again, this is a pretty good sign. We'll review the science behind Metabolic Flora in a below section.

Each bottle of Metabolic Flora is priced between $50 and $70. You can exclusively purchase it online through the official company website.

How Does Metabolic Flora Work?

Metabolic Flora claims to offer three main benefits. These include:

  • Supports healthy weight management
  • Supports healthy metabolic function
  • Supports overall digestive health

We see green tea extract and caffeine in other nutritional supplements. What makes Metabolic Flora unique, however, is the use of Bifidobacterium Breve B-3 (also known as B. breve). This probiotic bacteria was originally discovered in babies and breastmilk, and it has been the subject of relatively extensive scientific research since its initial discovery.

Adults have very little B. breve in their bodies. In one study, a doctor gave participants the probiotic and was surprised to find a significant drop in body fat with no changes in diet or exercise. After the study was published, several companies created B. breve supplements. Today, you can take B. breve probiotics to support healthy weight management.

Some studies also link B. breve with better digestive health. One study found significantly lower symptoms of colic in newborns, for example, after taking B. breve probiotics. B. breve soothed digestive irritability. It’s possible these effects work on adults and newborns alike.

Simple Promise claims that by combining B. breve with a healthy diet and exercise routine, you can maintain healthy body weight and support daily energy levels, among other benefits.

Other active ingredients in Metabolic Flora include green tea leaf extract and natural caffeine.

Green tea leaf extract is rich with polyphenols, catechins, and EGCG, all of which have been linked with various benefits. Green tea appears rich in antioxidants and anti-inflammatories, for example, which is why green tea is linked with various benefits. EGCG, similarly, is linked specifically with weight loss benefits, and studies show it could help support healthy weight loss.

Caffeine is a popular weight loss aid found in plenty of weight loss supplements. Caffeine may induce thermogenesis, encouraging your body’s natural fat burning processes. At the very least, caffeine boosts physical and mental energy, making it easier for you to work out and stay active.

Metabolic Flora Ingredients

B. breve is one of three main ingredients in Metabolic Flora, including:

  • Morinaga Bifidobacterium Breve B3 (B. breve): Morinaga is a registered trademark formula containing Bifidobacterium breve B3 (B. breve). Each two capsule serving of Metabolic Flora contains 225mg of B. breve.
  • Green Tea Leaf Extract: Metabolic Flora contains 383.4mg of green tea leaf extract (Camellia sinensis) standardized to contain 98% polyphenols (375.8mg of polyphenols), 80% catechins (306.7mg of catechins), and 70% EGCG (270mg of EGCG).
  • Natural Caffeine: Metabolic Flora contains 150mg of natural caffeine (from Coffee Arabica extract), which is about the amount of caffeine in one large cup of coffee.

Other, inactive ingredients in Metabolic Flora include Hypromellose (a vegetable capsule), inulin, vegetable stearates, and silicon dioxide.

Scientific Evidence for Metabolic Flora

Simple Promise has not conducted any clinical trials or scientific studies on its formula. However, the company cites 10 studies supporting its various claims.

Simple Promise cites this 2018 study, for example, which showed Bifidobacterium breve B-3 (B. breve) reduced body fat in pre-obese adults in a randomized, double-blind, placebo-controlled trial. Pre-obese adults (with a BMI between 25 and 30) randomly received either a placebo or B. breve capsules for 12 weeks. The B. breve group had significantly lower body fat mass and percent body fat than the placebo group.

Other studies show B. breve can reduce symptoms of colic in newborns. Colic is linked with gastrointestinal distress. By giving infants the B. breve probiotic, researchers inhibited gas-producing coliforms, reducing colicky behavior.

Simple Promise does not cite any studies supporting its other ingredients, including green tea extract and caffeine.

As Mayo Clinic explains, coffee is linked with weight loss results. Caffeine alone will not help you slim down, although it could slightly boost weight loss efforts or prevent weight gain. Some studies have found that even decaffeinated coffee is linked with weight loss, which suggests the weight loss results come from more than just caffeine. Researchers believe caffeine suppresses appetite and increases energy use, burning more calories while reducing calorie intake.

Green tea is also linked with weight loss. In one study involving 60 obese individuals, participants taking green tea extract lost 7.3 more pounds (3.3kg) and burned 183 more calories per day after three months compared to those who did not take the extract. Other studies have linked the polyphenols in green tea with powerful health benefits, cardiovascular effects, and more.

Overall, there’s evidence Metabolic Flora works as advertised to support digestion, weight loss, and more.
