MEGA IGG2000 POWDER FAQSCommon questions about Microbiome Labs Mega IgG2000 Powder
What is Microbiome Labs Mega IgG2000 Powder used for?

Microbiome Labs Mega IgG2000 Powder is designed to support gut barrier integrity, digestive resilience, mucosal immune balance and overall gastrointestinal wellbeing. It provides serum-derived bovine immunoglobulins in a flexible powder format.

Is Microbiome Labs Mega IgG2000 Powder a probiotic?

No. Microbiome Labs Mega IgG2000 Powder is not a probiotic because it does not contain live bacteria. It is an immunoglobulin concentrate designed to support the gut barrier and mucosal immune system.

What are immunoglobulins?

Immunoglobulins are proteins involved in immune defence and immune signalling. In the gut, immunoglobulins may help support mucosal barrier integrity, microbial balance and digestive resilience.

How is Mega IgG2000 Powder different from Mega IgG2000 capsules?

Mega IgG2000 Powder provides the same key immunoglobulin-support concept in a powder format, while the capsule version is taken as capsules. The powder may suit people who prefer mixing their supplement into water or another cold liquid.

Is Microbiome Labs Mega IgG2000 Powder dairy-free?

Yes. Microbiome Labs Mega IgG2000 Powder is derived from bovine serum, not dairy. It is listed as free from lactose, casein and β-lactoglobulin, making it different from milk-derived immune protein products.

Is Microbiome Labs Mega IgG2000 Powder suitable for vegans or vegetarians?

No. Microbiome Labs Mega IgG2000 Powder is not suitable for vegans or vegetarians because it is derived from bovine serum.

How do you take Microbiome Labs Mega IgG2000 Powder?

Adults can take 1 scoop daily, with or without food, or as directed by a healthcare professional. Mix the powder into approximately 250–300 mL of cold water or a preferred cold liquid and stir well.

Can children take Microbiome Labs Mega IgG2000 Powder?

Can Microbiome Labs Mega IgG2000 Powder be taken with probiotics?

Microbiome Labs Mega IgG2000 Powder may be used alongside probiotics when suitable, as they work in different ways. Probiotics support gut microbial balance, while immunoglobulins support gut barrier and mucosal immune function.

Speak with a healthcare professional before using Microbiome Labs Mega IgG2000 Powder if you are pregnant, breastfeeding, immunocompromised, taking medication, managing a digestive or immune condition, allergic to bovine-derived ingredients, shopping for a child, or experiencing ongoing gut symptoms.
