All-Natural Anti/biotic Alternative — Cold & Flu Support — 90 Vegetarian Capsules
Formulated with 14 Clinically Researched, All Natural Ingredients for Cold & Flu Support*
We all know when a cold or flu is going around—at school, church, or in the community—our families choose to begin taking this product at the earliest signs of these illnesses to help support immune health and overall wellness.* Certain botanicals in this supplement - such as echinacea, garlic, olive leaf, astragalus, and reishi—have been studied for their ability to support immune response and may be associated with shorter duration or reduced severity of seasonal colds when taken at the first sign of symptoms.*
Designed for rapid support at the first sign of seasonal challenges. Our research-aligned blend of 14 botanicals — Garlic (odorless), Red Clover, Turmeric/Curcumin, Echinacea, Burdock, Reishi, Olive Leaf, Astragalus, Barberry, Grapefruit Seed Oil, Neem Oil, Pau d’Arco, Goldenseal, and Caprylic Acid — supports immune defenses and a healthy inflammatory response for cold & flu season.* Produced in FDA-registered, GMP-certified facilities and
third-party tested for identity, purity & potency.
Research Promise: At LifeSource Vitamins, our commitment is rooted in research and results. Every benefit below is supported by human clinical studies indexed in the National Institutes of Health (NIH) via PubMed, with full texts available in the National Library of Medicine (NLM) PubMed Central (PMC) when available.

When you feel something coming on: Take 2 capsules in the morning with food and 2 in the afternoon with food for 3–4 days; then 1 capsule morning + 1 capsule afternoon until you feel better, plus 3 additional days.*
Clinically Studied Benefits (with research)
• Garlic (allicin) — fewer colds & sick days* — Double-blind RCT showed reduced incidence and duration of common colds vs placebo. (NIH/PubMed — Josling, 2001)

• Echinacea — cold risk/duration* — Systematic reviews and RCTs report mixed but overall supportive signals for reducing risk/duration when started early. Cochrane Library — 2014 ; NIH/PubMed — Barrett, 2010 ; NIH/PubMed — Goel, 2004
• Echinacea in children — fewer RTIs & less antibiotic use* — Blinded RCT reported reduced respiratory infections and antibiotic use. (NIH/PubMed — Ogal, 2021)
• Curcumin — inflammatory balance* — Meta-analyses across human RCTs show reductions in CRP/IL-6/TNF-α, supporting comfort during cold/flu. (NIH/PubMed — 2019)
• Astragalus — airway innate defenses* — Human airway epithelium research shows induction of LL-37 (cathelicidin) antimicrobial peptide. (NIH/PubMed — 2018)
Additional Studies Showing Promising Benefits*
• Olive Leaf — Antiviral activity with clinical signals in mucocutaneous infections; relevant context during viral seasons. (NIH/PubMed — 2022 RCT)
• Reishi (Ganoderma) — Immune-modulating polysaccharides summarized in a government-hosted academic monograph. (NCBI Bookshelf)
• Neem / Oral–nasopharyngeal hygiene — Broad antimicrobial potential across dentistry/skin reported in reviews; supports hygiene context during exposure. (NIH/PMC — 2022)
