Does Mary Ruth’s Probiotics Work?

  • North American Journal of Medical Sciences — “The results of the study concluded that lactobacillus acidophilus concentration of 1×108 cells/mL had a high activity to inhibit the growth in-vitro of all pathogenic gram-positive and gram-negative bacteria, which cause burn wound infections. This indicated the therapeutic efficacy of lactobacillus acidophilus bacteria.”

Mary Ruth’s Probiotics Claims

Mary Ruth’s liquid probiotic claims that its ingredients will help improve the immune function, assist in digestion, enhance weight loss, and increase energy levels by suppressing the bad bacteria in the GI tract.

However, some of the different supplements are made to have different benefits. For example, Probiotic Beauty+ is designed to reduce inflammation, improve skin health, and boost hair health. On the other hand, Probiotic Weight Management+ claims to enhance gut biome and aid in weight loss.


Mary Ruth’s Probiotics Ingredients

The ingredients in Mary Ruth’s Probiotics will depend on which product you choose. However, they generally contain the same bacterial strains. These include:

  • Lactobacillus acidophilus
  • L. rhamnosus
  • L. salivarius
  • L. casei
  • L. plantarum
  • Lactococcus lactis
  • Streptococcus thermophilus
  • Bifidobacterium bifidum

Do Mary Ruth’s Probiotics Work?

Lactobacillus acidophilus is a “good” bacteria that reside in the digestive tract and helps protect against the “bad” bacteria by making its environment unfriendly. According to the International Journal of Medical Sciences, this strain of bacteria is considered strong since it can survive extreme gastrointestinal tract conditions.

L. rhamnosus strain GG was discovered in 1985. It was originally isolated from fecal samples of healthy human adults attempting to create an ideal probiotic resistant to stomach acid and bile. According to Frontiers in Pharmacology, this strain can help reduce the effects of diarrhea.

L. salivarius has explicitly been known to have antibacterial activity for oral health. It is helpful with dental plaque control, periodontal health, and oral malodor, as it helps prevent the development of dental caries, according to BMC Oral Health.

L. casei has been shown to restore health to the gastrointestinal tract after disturbing the microbiota, per Frontiers in Microbiology.

L. plantarum is a probiotic species found in the human gut and foods such as sourdough, sauerkraut, kimchi, and olive brine. According to the World Journal of Gastroenterology, it is popular for its ability to reduce abdominal pain and bloating.

Streptococcus thermophilus has antioxidant properties and helps with the inhibition of specific pathogens. According to the International Journal of Molecular Sciences, it is effective during its small intestine fermentation process.

According to Frontiers in Microbiology, Bifidobacterium bifidum has been shown to positively affect immunity by boosting the function of white blood cells. It is known to be effective in healing the GI tract after antibiotics use.

B. lactis is a powerful probiotic, as the scientific journal Microorganisms have proven that it can enhance immunity and improve digestion. It also helps support a healthy gastrointestinal microbiota while reducing the side effects of antibiotics.

B. infantis is a unique probiotic known for its anti-inflammatory properties and seems to grow and function better in the presence of human milk. According to Pediatric Research, in premature infants, B. Infants are given in combination with human milk to decrease bacterial growth.

B. breve has been shown to exert positive effects on obesity. One study published in Bioscience of Microbiota, Food, and Health found it was proven the bacteria could suppress body weight gain and visceral fat deposition.

B. longum has been shown to positively affect cognitive health, per one study published in Sports.

Weight Loss

Mary Ruth’s Probiotics and Weight Loss

There is one supplement from the brand that makes weight-loss-specific claims: Probiotic Weight Management+.

Its ingredients include 400 mg of Morosil, 315 mg of green tea extract, 250 mg of Garcinia cambogia extract powder, and 50 billion CFU of a probiotic proprietary blend. The probiotic ingredients include Lactobacillus plantarum, lactobacillus casei, and Lactobacillus acidophilus.

Morosil is suggested to help against fat accumulation, and green tea leaf extract has also been shown to be effective in the breakdown of fat.

Garcinia Cambogia is an herb found in Southeastern Asia, India, Nepal, and Sri Lanka. It contains hydroxycitric acid (HCA), which has been linked to weight loss benefits, as it is claimed to be an effective appetite suppressant, per LiverTox. However, it can have severe side effects.

Side Effects

Mary Ruth’s Probiotics Side Effects

It is always recommended that patients consult with their physician before starting any supplements.

The liquid probiotic is extracted from grass, so individuals with allergens should consult with their physician before starting any supplements.

Pregnant and lactating women and seniors over the age of 65, should consult a physician before starting any supplements. Customers should discontinue use if any negative reactions occur.
