Probiotics and gut health

The human gut contains a vast ecosystem of microbes, which play a crucial role in immune function, digestion, and energy metabolism. Probiotics help recolonise the gut by introducing microbial strains that are known to have a beneficial effect on our health. By nourishing the internal ecosystem, you and your customers can enjoy greater digestive comfort and general well-being.

Research shows that even when in transit, probiotics can have a positive impact on gene expression and immune regulation(1)(2). There are also studies showing that specific gut flora can activate neural pathways, with the brain and gut physically and biochemically connected via the gut-brain axis(3).

Why we recommend Smidge® Sensitive Probiotic

Smidge® Sensitive Probiotic contains the most beneficial and human-compatible strains for our gut microbiome, each of which is backed by clinical research. This custom probiotic formula is one of the most potent available with over 25 billion CFUs per serving. However, it is not just what goes into Smidge® Sensitive Probiotic that matters, what is left out is just as important. Smidge® Sensitive Probiotic does not contain additives, excipients, or fillers such as silica or magnesium stearate.

Pure, powerful and therapeutic grade, Smidge® Sensitive Probiotic is a 100% probiotic powder, with eight clinically-proven strains of beneficial bacteria. Premium strains are carefully calibrated to aid digestion and minimise potential problems associated with other commercial brands. That means omitting certain strains that can cause histamine intolerance, d-lactic acidosis, and other reactions.

Studies show that the strains in Smidge® Sensitive Probiotic can help "kick-start" the digestive system, maximise nutrient absorption from a real-food diet, and ultimately support the entire immune system. And because Smidge® Sensitive Probiotic contains only pure probiotics and zero fillers and binders, it is ideal for sensitive individuals, as well as anyone wanting to improve overall health and well-being. Available in powder and capsules, this incomparable formula is based on years of research and clinical results to improve gut health.

What is the difference between Smidge® Sensitive Probiotic powder and capsules?

Smidge® Sensitive Probiotic powder and Smidge® Sensitive Probiotic capsules contain the same formula: the same strains in the same proportions.

Smidge® Sensitive Probiotic capsules contain cellulose and L-leucine, which are required to keep the powder in capsule form. Smidge® Sensitive Probiotic capsules have 5 billion CFUs per capsule, allowing easy titration of doses. 

Smidge® Sensitive Probiotic powder does not contain any additional ingredients at all. While the powder contains 3 trillion CFUs per bottle; the capsules contain 300 billion CFUs per bottle. In other words, one bottle of Smidge® Sensitive Probiotic powder equals 10 bottles of Smidge® Sensitive Probiotic capsules.

Although the powder costs more upfront, it is much cheaper in the long run. For families using the same probiotic, we recommend Smidge® Sensitive Probiotic powder as you can easily titrate individual doses to suit each person. 

How do you take Smidge® Sensitive Probiotic?

The Smidge® range of digestive health supplements is premium, pure and powerful. Therefore, it is vitally important to start slowly, with a lower dose than recommended. When starting with Smidge® Sensitive Probiotic powder, it is best to start low and slow with a minimum dose every other day.

The dosage spoon comes with Smidge® Sensitive Probiotic Powder, so you can accurately measure your desired dose of probiotic powder.

Nutritional information

Smidge® Sensitive Probiotic contains only the highest-quality probiotic bacteria. All strains have been thoroughly investigated, documented, and stored in recognised microbial culture collections. Additionally, all strains are non-GMO and certified by the American Type Culture Collection.

Below is a list of ingredients in Smidge® Sensitive Probiotic and information on why each has been included:

L. gasseri: Lactobacillus gasseri is a strain of the genus Lactobacillus, a family of bacteria found naturally in the human digestive and urinary tracts. L. gasseri is believed to suppress harmful bacteria and, in turn, aid digestion. Preliminary research indicates that L. gasseri may inhibit inflammation signalling at the genetic level. *

L. salivarius: Lactobacillus salivarius is one of the most prevalent probiotic species in human saliva. It produces organic acids, such as lactic acid and acetic acid from carbohydrates, which can inhibit the growth of surrounding microorganisms and produce hydrogen peroxide and other antimicrobial substances. L. salivarius appears to help keep the microbial population in the mouth healthy. * Additionally, several clinical trials in adults and children indicate that L. salivarius appears to help regulate the immune system and, as a result, maintain healthy skin. *

B. bifidum: Bifidobacteria are a group of good bacteria that normally live in the human intestines and stomach. They help the body perform essential functions such as digestion and the maintenance of beneficial bacteria. A randomised, placebo-controlled study showed that B. bifidum can help with stress-related diarrhoea. * And a clinical study showed that B. bifidum helped college students with academic stress get through the winter semester with far fewer absences due to cold and flu than students who did not take the probiotic. * Additionally, clinical research suggests that B. bifidum may help maintain comfortable joint movement by helping the body control inflammation. *

B. breve: Bifidobacterium breve is one of the most useful probiotic bacteria in the human body due to its unique ability to compete with harmful bacteria by digesting a wide variety of molecules. It also comprises most of the bacteria in the colon of breastfed babies. In some clinical trials with premature babies, B. breve has been shown to work especially well to establish a healthy colony of bacteria in the gut. *

B. infantis: Bifidobacterium infantis is a type of beneficial lactic acid bacteria found naturally in the human mouth and gastrointestinal tract; and helps maintain a healthy digestive tract. Regarding potential antidepressant properties, research suggests that B. infantis regulates the production of tryptophan, which is the precursor to serotonin (serotonin is the neurotransmitter associated with a feeling of satisfaction and happiness). *

B. Longum: Bifidobacterium longum is a species of microscopic, non-pathogenic bacteria that occurs naturally in the gastrointestinal tract of humans. It produces lactic acid from the fermentation of sugar in the intestine and is one of the first bacteria to colonise our body at birth. B. longum has been associated with helping digest milk and other difficult foods. *

B. lactis: Bifidobacterium lactis is an effective transient probiotic bacterium that inhabits the human intestines and colon in large numbers. Generally, its function is to break down body waste and aid in the absorption of various vitamins and minerals. B. lactis shows exciting promise in laboratory research to interfere with the body's reaction to certain toxins in wheat. *

L. plantarum: Lactobacillus plantarum is a beneficial plant-based probiotic species found naturally in fermented foods such as sauerkraut.
