Primal Harvest Probiotics is a pre and probiotic supplement that supports a healthy gut microbiome and immune system.
Probiotics have skyrocketed in popularity over the last few decades and for good reason. With extensive research ranging from benefits for gut and immune health to weight loss and even mental health benefits, everyone wants a piece.
However, the potential benefits of probiotics highly depend on the strain, the amount of colony-forming units (CFUs), and many other factors. This makes choosing a high-quality probiotic supplement a challenge for the average consumer. That’s where we come in.
Today’s article reviews a popular option, Primal Harvest Probiotics (also known as Primal Probiotics). Marketed with a holistic philosophy, Primal Harvest products have been featured on CNN, Good Housekeeping, and People, but does their popularity really prove quality? We’ll find the answer to that question and many more in this Primal Harvest Probiotics review!

About Primal Harvest Probiotics
Primal Probiotics are a probiotic capsule supplement from a popular supplement company, Primal Harvest. They are known for supplements designed to cater to the needs of your overall health.
Primal Probiotics contains 31 billion CFUs from 12 different beneficial bacteria sources, including Lactobacillus and Bifidobacterium strains.
Founded in 2018 by Dan Harper in Farmingdale, New York, Primal Harvest boasts a holistic philosophy, encouraging supplements over pharmaceuticals.
Their website reports their supplement ingredients are based on scientific research and standardized clinical studies. Additionally, all Primal Harvest products are made in the United States and are Good Manufacturing Practices (GMP) certified.
Primal Probiotics Benefits
“Probiotics are defined as “live microorganisms that, when administered in adequate amounts, confer a health benefit on the host” [1].
Our digestive system contains a microbiome of bacteria, fungi, and other microorganisms that, in a healthy person, would exert positive functions such as aiding in metabolism and protecting us from pathogenic organisms.
With a broad spectrum of potential health benefits ranging from gut health to immune function, probiotics are still being extensively studied for their use in human health.
Evidence shows probiotics can help to prevent and/or treat certain conditions, including bowel disorders such as diarrhea (antibiotic-associated and infectious), lactose intolerance, and allergy symptoms.
Other benefits show promise; however, they remain controversial due to the limited research available in human trials on their safety and efficacy [2].
Other possible benefits of probiotics are included below.
Gut Health
Probiotics are believed to help balance good bacteria in our gut for improved digestion and decreased digestive upset symptoms such as constipation and diarrhea.
Mental Health
Some studies have shown probiotics to improve some mental health disorders such as anxiety, depression, obsessive-compulsive disorder (OCD), and even cognitive disorders such as memory loss [3].
Heart Health
Probiotics are believed to be able to improve heart health by reducing our bad cholesterol (LDL) levels and even possibly improving our good cholesterol (HDL) levels [4].
Allergies and Immunity
Some studies have shown probiotics to help improve allergy symptoms and immune system function. Because most of our immune system functions within our gut, these healthy bacteria can help to support our body’s ability to fight illness and infection [5, 6]
Weight
Probiotics have also been linked to aiding in weight loss through many potential pathways, including the excretion of dietary fat and increasing our feeling of fullness during meals [7].
Does Primal Harvest Probiotics Work?
Primal Probiotics consumers have reported experiencing improved gut health with a reduction in symptoms for various complaints such as IBS and Crohn’s, as well as general diarrhea or constipation symptoms.
Claims vs. Reality
Primal Probiotics claims to “promote good gut bacteria growth and improves immune response.”
These are the same claims favored by numerous research studies; however, further research is needed on these supplements and their potential benefits and safety of use.
Primal Harvest Probiotics Ingredients
Primal Probiotics’ formula contains 31 billion CFU from 12 different beneficial bacteria sources.
Primal Harvest supplements do not contain any gluten, eggs, dairy, or soy in the capsules due to allergy concerns, and they are vegetarian-friendly. Their supplement does not require refrigeration like some other probiotics, such as You Gut This, making Primal Harvest Probiotics more convenient for most consumers.
Below, we’ve detailed some of the bacterial strains in Primal Harvest Probiotics.
Marketed Ingredients
- Lactospore (Bacillus coagulans) – Lactospore is a spore-forming, lactic acid-producing, heat-resistant bacterium that is more likely to survive in our digestive tract as well as during the heating and processing of food and supplement production than other probiotic forms. Lactospore is reported safe by the Food and Drug Administration (FDA) and European Union Food Safety Authority (EFSA). It is on the Generally Recognized As Safe (GRAS) list and the Qualified Presumption of Safety (QPS) list [8].
Studies have shown Lactospore to improve bloating, vomiting, diarrhea, abdominal pain, and stool frequency for IBS patients [9].
- Bifidobacterium Lactis – Those with IBS experience a reduction in the variety of healthy organisms in their gut, often with low levels of lactobacillus and Bifidobacterium. The Bifidobacterium Lactis strain has been shown to reduce abdominal pain severity in IBS patients and normalized stool type when added as a supplement [10].
- Preforpro Probiotic Booster – Similar action to a prebiotic, Preforpro acts as a bacteriophage (a virus that infects and replicates within bacteria) and is said to work with a broad spectrum of probiotics to boost their function. Preforpro does not cause gas or require large amounts to function, which gives them an advantage over starch-based prebiotics.
Several small studies found Preforpro to benefit our gut bacteria, including reducing E-Coli and pro-inflammatory bacteria for a healthier gut environment [11, 12].
- Lactobacillus Casei 12 billion – Studies show that Lactobacillus Casei can, directly and indirectly, affect human health; however, it is still poorly understood and requires further study because of its complicated history and numerous strains. Its benefits are believed to range from enhancing brain function to anti-cancer activity, immune modulation, pathogen resistance, and improved barrier function [13].
- Lactobacillus Plantarum 8 billion – Studies have shown Lactobacillus Plantarum benefits ranging from improving our immune response to antioxidant and antigenotoxic properties. However, like Lactobacillus Casei, more research is still needed to fully understand and isolate the mechanism of action for these various strains in regard to human health [14].
Primal Probiotics Safety
Primal Probiotics is a potent probiotic supplement, and the side effects reported were limited and mild, including upset stomach, diarrhea, gas, and bloating.
The FDA generally recognizes probiotics as safe because these microbes naturally exist in our bodies. These supplements are not recommended or should be used with caution for those who have a weak or compromised immune system which can put you at risk for developing illnesses.
Who is Primal Probiotics Best For?
Those who wish to improve digestion or who suffer from a digestive ailment such as IBS or Crohn’s, or who struggle with getting enough probiotics from food sources might benefit from this probiotic supplement.
Natural food sources of probiotics include fermented dairy products such as yogurt or kefir and other fermented foods such as pickles, kimchi, sauerkraut, miso, and tempeh.
