Ingredients & Science Behind Daily Pre+Probiotic Melts Kids
What's inside and why
Every ingredient has a reason to be here.
Every dose is grounded in research. Every ingredient is lab-verified by an independent third party. Here's exactly what we put in — and why.
Most supplement brands tell you what's in their products. Fewer tell you how much. And almost none tell you why that amount was chosen, or show you the evidence to back it up.
We think you deserve all three. This page covers every active ingredient in Purest Kids Daily Pre+Probiotic Melts Kids, why it's included, what the science says, and how we verified it.
If you have questions after reading, our full certificates of analysis are linked at the bottom of this page.
What's Inside
Ingredient Deep Dives
Bovine Colostrum (30% IgG)
Bovine Colostrum (30% IgG)
Colostrum is the first milk produced by cows in the 24–48 hours after birth. It is exceptionally rich in immunoglobulins -- antibody proteins, predominantly IgG, that play a direct role in immune defence. IgG concentration is at its absolute peak in the first milking after birth, then drops sharply with each subsequent milking.
Most colostrum supplements use material with 10–20% IgG concentration, sourced from pooled milkings. Ours is standardised to 30% IgG, sourced exclusively from Day 1, first-milking Grade A dairies -- the single window when concentration is highest.
Each sachet delivers 167mg of this high-concentration colostrum. Beyond immune support, colostrum contains lactoferrin and growth factors that support gut lining integrity -- which is why it works well alongside probiotic strains rather than as a standalone.
Probiotic Blend (10 Billion CFUs · 7 Strains)
Probiotic Blend (10 Billion CFUs · 7 Strains)
Lactobacillus plantarum, Bifidobacterium lactis, Lactobacillus brevis, Lactobacillus fermentum, Lactobacillus reuteri, Lactobacillus rhamnosus, Lactobacillus casei
CFU count alone is not a meaningful measure of probiotic quality. What matters is how many live cultures actually reach the intestines -- the only site where probiotics exert their effect. Stomach acid destroys a significant portion of unprotected cultures before they arrive.
Our formula delivers 10 billion CFUs across 7 clinically studied strains, each protected by a patented 4-layer microencapsulation coating designed to carry live cultures through stomach acid. The 7-strain blend is intentional: different strains colonise different parts of the gut and perform different functions. A diverse blend supports a more resilient microbiome than a single high-CFU strain alone.
The 7 Strains
The 7 Strains
L. rhamnosus - one of the most studied paediatric strains; supports immune modulation and reduces duration of common childhood illnesses
L. reuteri - supports gut motility, reduces colic symptoms, and has demonstrated anti-inflammatory properties
B. lactis - strongly linked to improved immune response and reduction in upper respiratory tract infections in children
L. plantarum - supports gut barrier integrity and helps maintain microbial balance during and after antibiotic use
L. casei - supports digestive comfort and has been studied in relation to allergy symptom reduction
L. fermentum - antioxidant properties; supports immune cell activity
L. brevis - produces GABA, a neurotransmitter with a role in mood regulation and stress response via the gut-brain axis
Bromelain (5mg)
Bromelain (5mg)
Bromelain is a proteolytic enzyme derived from pineapple stem. At 5mg per sachet, it serves two roles in this formula. First, it acts as a digestive aid -- breaking down proteins in the gut and reducing occasional bloating and digestive discomfort. Second, and more relevantly here, bromelain has demonstrated mucosal activity: it helps thin and clear mucus in the digestive tract, which supports the absorption of both the probiotic strains and the colostrum IgG. It is included not as a standalone active but as a delivery enhancer for the other two ingredients.
