Formula details
What Ingredients Are in GumAktiv?
The seven highlighted ingredients are Lactobacillus paracasei, B. lactis BL-04, Lactobacillus reuteri, malic acid, inulin, tricalcium phosphate and peppermint.
Bifidobacterium lactis BL-04
B. lactis BL-04 is a named Bifidobacterium strain. A 2023 systematic review examined Bifidobacterium probiotics in oral health, but evidence varies by strain and outcome.
Lactobacillus reuteri
L. reuteri has been studied in lozenges and chewable tablets, often as an adjunct to periodontal treatment. Those trials do not establish that every L. reuteri formula has the same result.
Malic Acid
Malic acid is an organic acid used in food and supplement formulations. GumAktiv includes it within the supporting formula rather than as a stand-alone dental treatment.
Inulin
Inulin is a fermentable prebiotic fibre. Its role in the formula is to complement the probiotic ingredients.
Tricalcium Phosphate
Tricalcium phosphate supplies calcium and phosphate and is used in a range of dental and food applications.
Peppermint
Peppermint provides the fresh flavour expected from a chewable oral supplement.
Are the Individual Probiotic Quantities Disclosed?
No. The official page gives a combined total of 3.5 billion probiotic organisms but does not state how that total is divided among the three strains.
This means buyers can confirm the strain names and combined count but cannot compare each strain quantity with a specific clinical study.
Research context
What Does Research Say About Oral Probiotics?
Research supports continued study of probiotics for oral health, but outcomes depend on the exact strain, dose, delivery method, dental condition and accompanying treatment.
2023 Systematic Review
A systematic review found possible oral-health applications for probiotics while emphasising that changing a stable oral microbiota is complex.
2014 L. paracasei Trial
A strain-specific randomised trial found reduced salivary mutans streptococci after L. paracasei SD1. GumAktiv does not identify its L. paracasei as SD1.
2023 Bifidobacterium Review
A systematic review assessed Bifidobacterium probiotics in oral health. Findings should not be assumed to apply equally to every Bifidobacterium strain.
2013 L. reuteri Trial
A randomised trial studied L. reuteri lozenges as an adjunct to scaling and root planing for chronic periodontitis.
2021 Chewable Trial
A trial examined L. reuteri chewable tablets alongside initial periodontal therapy and reported improvements compared with therapy alone.
Evidence Limitation
These studies do not test the complete GumAktiv formula, its exact strain combination or its supporting ingredients as one finished product.
