Probiotics are live microorganisms intended to benefit the host when consumed. Increasingly popular in New Zealand, these supplements are marketed for gut health, immunity, and even mental wellbeing. This article provides a detailed overview of probiotics in NZ, covering benefits, strains, choosing a supplement, and regulations.
What are Probiotics & Why are They Important?
Our gut microbiome – the trillions of bacteria, fungi, viruses, and other microbes living in our digestive tract – plays a crucial role in overall health. An imbalance (dysbiosis) can contribute to various issues. Probiotics help restore this balance.
- Digestion: Aid in breaking down food and nutrient absorption.
- Immunity: A significant portion of the immune system resides in the gut.
- Mental Health: The gut-brain axis links gut health to mood and cognitive function.
- Inflammation: Can help reduce inflammation throughout the body.
Common Probiotic Strains Available in NZ
Not all probiotics are created equal. Different strains have different effects. Here are some commonly found in NZ supplements:
- Lactobacillus: A large genus, including L. acidophilus (digestion, immunity) and L. rhamnosus (diarrhoea prevention).
- Bifidobacterium: Another key genus, with B. bifidum (immune support) and B. longum (gut health).
- Saccharomyces boulardii: A yeast probiotic, often used for antibiotic-associated diarrhoea.
Important Note: Look for supplements listing specific strains, not just genus and species. Strain identification (e.g., L. rhamnosus GG) is crucial.
Choosing the Right Probiotic Supplement in NZ
With numerous options, selecting a probiotic can be overwhelming. Consider these factors:
- Specific Health Goal: What are you trying to address? (e.g., IBS, antibiotic use, general wellbeing).
- CFU Count: Colony Forming Units (CFU) indicate the number of live bacteria. Higher isn’t always better; 1-10 billion CFU is often sufficient.
- Strain Diversity: A blend of strains may offer broader benefits.
- Delivery Method: Capsules, powders, and liquids are available. Some capsules are enteric-coated to protect bacteria from stomach acid.
- Storage: Some probiotics require refrigeration; others are shelf-stable.
- Brand Reputation: Choose reputable brands with third-party testing.
NZ Regulations & Quality Control
In New Zealand, probiotics are regulated as dietary supplements under the Food Standards Australia New Zealand (FSANZ) code. This means they don’t undergo the same rigorous testing as pharmaceuticals.
Look for:
- HACCP Certification: Indicates food safety standards.
- Third-Party Testing: Confirms potency and purity.
- Manufactured in a GMP-certified facility: Good Manufacturing Practices.
Potential Side Effects & Precautions
Probiotics are generally safe for most people. However, some may experience mild side effects like gas or bloating, especially when starting.
Precautions:
- Immunocompromised Individuals: Consult a doctor before taking probiotics.
- Serious Illness: If you have a serious medical condition, seek medical advice.
- Antibiotics: Take probiotics at least 2 hours apart from antibiotics.
