NUTRITIONIST INSIGHT
This kefir shot delivers 5 billion+ live cultures from 14 probiotic strains in just 90 calories. The added chicory fibre (3.3g per shot) acts as a prebiotic, feeding beneficial gut bacteria for a synbiotic effect that maximizes digestive benefits.
Myth Busters
MYTH #1: All Probiotics Are the Same
TRUTH: Not all probiotics are equal. This kefir shot contains 14 specific strains including Bifidobacterium and Lactobacillus species that have been studied for gut microbiome modulation. Strain diversity matters more than total count for comprehensive gut health benefits.
MYTH #2: Kefir Shots Are Too High in Sugar
TRUTH: At 8.4g sugars per 150ml, much of this comes from naturally occurring lactose and berry fruit sugars. Compare this to a typical fruit juice at 15-20g sugars per 150ml. The probiotics in kefir may actually help moderate blood sugar response.
MYTH #3: You Need Supplements for Gut Health
TRUTH: Fermented foods like kefir provide more diverse probiotic strains than most supplements. A single kefir shot can contain 50+ species of bacteria and yeast, working synergistically in ways isolated strains cannot replicate.
MYTH #4: Kefir Causes Bloating
TRUTH: While some people experience initial adjustment, kefir actually improves lactose tolerance and digestive function over time. Start with half a shot daily and increase gradually to minimize any initial digestive discomfort.
MYTH #5: Pasteurized Kefir Has No Benefits
TRUTH: While raw kefir may have more live cultures, pasteurized kefir products like this M&S shot still contain added live cultures (5 billion+ CFU) introduced after pasteurization. The bioactive peptides and postbiotics also provide health benefits beyond live bacteria alone.

Blood Sugar Response to Berry Kefir Shot
Understanding how this kefir shot affects your blood glucose can help you make informed decisions about when and how to consume it.
Typical Glucose Response Curve
*This chart shows typical blood glucose response for general healthy individuals. Individual responses may vary. Not medical advice.*
How to Flatten the Spike
Pairing kefir with protein or healthy fat slows glucose absorption and reduces the peak blood sugar level:
- 🥜 A handful of almonds or walnuts - Adds healthy fats and slows sugar absorption
- 🥚 Boiled eggs or egg whites - Provides complete protein alongside probiotics
- 🥑 Avocado on toast - Healthy fats complement the probiotic benefits
- 🫘 Oatmeal with seeds - Fiber combination further stabilizes blood sugar
This kefir shot already has a relatively low glycemic impact due to its chicory fiber content and fermentation process.
