Both Metamucil and probiotics are good for digestive health. Metamucil is a fiber supplement; this brand name is also an over-the-counter laxative to treat constipation. In comparison, probiotics are live helpful bacteria and yeasts that are good for the gut. The following discussions delve into their differences. 

What is Metamucil? 

Metamucil is a fiber supplement made from psyllium (a shrub-like herb called Plantago ovata and sometimes called ispaghula). 

Uses:

It is used to treat occasional constipation; high cholesterol when combined with proper diet; and other related purposes (Multum, 2020). It is advertised as helpful in maintaining blood sugar levels, heart health, and electrolytes absorption. Also, Metamucil’s soluble fiber may promote weight loss as it curbs hunger and slows down digestion (Procter & Gamble, 2020).

Dosage: 

Adults are generally recommended to take one dose in 8 ounces of liquid. Children, 6 to 11 years old, are recommended to take half a dose in 8 ounces of liquid (Your Health Remedy, 2018). 

Ingredients: 

This brand is advertised to have 100% natural psyllium husk (Procter & Gamble, 2020). Metamucil has 70% soluble fiber and 30 % insoluble fiber. Specifically, the product “Smooth Texture Sugar-Free Unflavored Metamucil Powder” has sodium, calcium, citric acid, potassium, and maltodextrin (Drugs.com, 2020). Metamucil’s other flavors (i.e., orange flavor) and versions (i.e., course milled, capsules, etc.) contain inactive ingredients such as artificial orange flavor, sucrose, Yellow 6, and natural citric acid (Your Health Remedy, 2018). 

Side Effects: 

The side effects may include stomach pain, difficulty swallowing, skin rash, vomiting, itching, nausea, and difficulty breathing (Your Health Remedy, 2018).

What are Probiotics?

Probiotics (from the Latin preposition “pro” which means “for” and the Greek word “biotic” which means life) are live helpful bacteria and yeasts that are good for the gut (Felson, 2020). 

Benefits 

The health-boosting spectrum of probiotics include the following (Aponte, et al., 2020): 

• Helpful in alleviating lactose intolerance

The consumption of Streptococcus thermophilus and Lactobacillus delbrueckii subsp. Bulgaricus in yogurt has been shown to be helpful in alleviating lactose intolerance. 

• Helpful in alleviating gastrointestinal tract disorders 

• The use of Leuconostoc cremoris and Bacillus, Bifidobacterium, Lactobacillus, Lactococcus, Saccharomyces, or Streptococcus spp. (individually or in combination) was found out to have a protective effect in treating antibiotic-associated diarrhea.
• Probiotics showed a statistically significant efficacy in preventing traveler’s diarrhea. 
• Probiotics has been found out to improve the health of the gastro-intestinal tract and the immune system; they are recommended to help people with inflammatory bowel diseases and Helicobacter pylori infection. 
• May decrease the risk or duration of respiratory tract infections 
• A study showed that yogurt added with Lactobaciillus paracasei N1115 can mitigate respiratory tract infections by increasing T cells. 

Moreover, probiotics have been studied to be helpful in alleviating other conditions such as urinary tract infections, chronic kidney diseases, bacterial vaginosis, androgenetic alopecia, dental carries, osteoporosis, hand, foot, and mouth disease, immunity disorders, and metabolic disorders. 

Dosage 

The optimal dose of probiotics depends on the product, strain, and condition. For instance, it was observed that taking Lactobacillus rhamnosus GG 1 to 2 x 10¹⁰ colony forming units (CFU) per day reduced antibiotic-associated diarrhea risk in children by 71%. Moreover, clinical trials showed that a daily dose of at least 10¹⁰ CFU Lactobacillus rhamnosus GG is most effective in treating infectious diarrhea (National Institutes of Health, 2020). Although there is no general dosing recommendation, the common dosage for adults is 5 billion to 10 billion CFU daily (Harvard Health Publishing, 2021). 

Common Kinds and Sources of Probiotics

Many probiotics are naturally living in the body, they are also found in fermented products such as yogurt, some cheeses, and pickled vegetables. The common species are Bifidobacteria (usually used in food and supplements), Lactobacillus (naturally found in the mouth, small intestine, and vagina). The common strains include B. animalis, B.breve, B. lactis, B. longum, L. acidophilus, and L. reuteri (Hecht, 2017). 

Risk/ Side Effects  

One theoretical risk is that a person can get sick from probiotics if his immune system has been weakened by illness or medication (Harvard Health, 2019). Though probiotics are generally safe, the side effects may include bloating, headaches, and increase histamine levels (Julson, 2017).
