SRW Imm1 Defence Immune Support Supplement for Healthy Immune Response

Product Overview

SRW Imm¹ Defence addresses multiple layers of the immune response through a combination of Muno-IgY™, a purified natural glycoprotein isolate derived from egg yolk immunoglobulins (IgY), and Quercefit® — a highly bioavailable form of quercetin formulated using Phytosome® technology to achieve superior intestinal absorption compared to standard quercetin extracts. IgY (immunoglobulin Y) is structurally analogous to mammalian IgG and has been the subject of more than 1,300 peer-reviewed research papers indexed in the National Institutes of Health National Library of Medicine, documenting its role in mucosal and systemic immune modulation.

The formulation was developed by SRW Laboratories with scientific advisory input from Dr. Paul Kilgore, an epidemiologist with nearly three decades of expertise in vaccine research, immunisation programs, and the clinical development of IgY for protection against viral pathogens. Synergistic micronutrients — Zinc, Vitamin D3, Vitamin C, and Vitamin B1 — support innate and adaptive immune function, with Zinc assisting quercetin's intracellular delivery via zinc ionophore activity and Vitamin D3 supporting immune regulatory (Treg) cell differentiation. All actives are encapsulated in delayed-release HPMC vege capsules to protect acid-sensitive components through the gastric environment.

Supplement Facts

Clinical Applications

• Mucosal immune support: Muno-IgY™ supports mucosal immunoglobulin defence — the first line of adaptive immune protection at respiratory and gastrointestinal mucosae — by providing exogenous IgY that complements endogenous secretory IgA activity.
• Zinc ionophore activity (quercetin-zinc synergy): Quercetin acts as a zinc ionophore, facilitating intracellular zinc delivery; intracellular zinc inhibits RNA-dependent RNA polymerase (RdRp) of RNA viruses, impairing viral replication — a mechanism documented in in vitro antiviral research.
• Innate immune activation: Vitamin D3 at 15 mcg supports differentiation of monocytes into functional macrophages and promotes production of cathelicidin (LL-37), an endogenous antimicrobial peptide active against enveloped viruses and bacteria.
• Antioxidant immune co-factor support: Vitamin C (300 mg) supports neutrophil chemotaxis, phagocytosis, and oxidative burst capacity; high-dose Vitamin C supplementation has been associated with reduced duration and severity of upper respiratory tract infections in meta-analyses published in the Cochrane Database.
• Energy support during recovery: Vitamin B1 (thiamine) supports the pyruvate dehydrogenase complex and ATP synthesis — processes under heightened demand during immune activation and febrile illness, where metabolic energy expenditure is substantially elevated.
• Year-round immune maintenance: Suitable for Singapore adults in high-exposure environments (healthcare, education, travel), immunosuppressed individuals under medical supervision, and those seeking evidence-based supplementation between illness episodes.

Frequently Asked Questions

Q: What is Muno-IgY™ and how does it differ from colostrum or bovine immunoglobulin supplements?
A: Muno-IgY™ is a purified natural glycoprotein isolate (IgY fraction) derived from egg yolk. Unlike bovine colostrum (which contains IgG, IgA, and IgM from mammalian sources), IgY is the avian immunoglobulin equivalent and does not fix mammalian complement, reducing the risk of complement-mediated inflammatory side effects. IgY has been studied in more than 1,300 peer-reviewed publications for its role in passive immune support against bacterial and viral pathogens.

Q: Is SRW Imm¹ suitable for individuals with egg allergies?
A: Muno-IgY™ is derived from egg yolk. Individuals with documented egg allergies should not use SRW Imm¹ without prior consultation with a physician or allergist. Egg yolk proteins are distinct from egg white proteins (which include ovalbumin and ovomucoid — the most common allergens), but cross-reactivity cannot be excluded in sensitised individuals. EMIS Asia recommends medical review for any individual with food allergy history before commencing this supplement.

Q: Why does SRW Imm¹ use Quercefit® instead of standard quercetin?
A: Standard quercetin has poor oral bioavailability due to its low aqueous solubility and extensive first-pass metabolism. Quercefit® uses Phytosome® technology to complex quercetin with phosphatidylcholine, significantly increasing intestinal absorption. In comparative studies, Quercefit® achieved substantially higher plasma quercetin concentrations than unformulated quercetin at the same dose, ensuring that therapeutic intracellular concentrations relevant to zinc ionophore activity are more reliably achieved.

Q: Can SRW Imm¹ be taken continuously or is it recommended only during illness?
A: SRW Imm¹ is designed for daily use as a maintenance immune support supplement, not exclusively for acute illness. Continuous use at 2 capsules daily provides consistent Zinc, Vitamin D3, and Vitamin C levels to support baseline immune competence. During periods of increased immune challenge, higher-dose short courses may be appropriate under medical guidance, but this is not the standard protocol advised on the label.

Q: Is SRW Imm¹ available through Singapore healthcare providers or hospitals?
A: Yes. EMIS Asia supplies SRW Imm¹ to Singapore healthcare professionals, integrative medicine practices, and corporate health programmes. The supplement is classified under Singapore's HSA Health Products Act as a health supplement and does not require medical device registration. Bulk procurement pricing is available for institutional customers.
