🛡️ 7-Layer Immune Shield

Your immunity needs more than Vitamin C.

7 ingredients protecting on 3 levels: natural barrier (colostrum), cellular defense (quercetin + zinc), and long-term support (Lion's Mane + D3).

🤧 Sound familiar? A cold every season change. Chronic fatigue. Slow recovery. You've been taking vitamin C and zinc — but your immunity still lets you down? That's probably because the gap is at the natural barrier level, not just vitamins.

3 Levels of Immune Defense

Each ingredient covers a different layer of your immune system.

🛡️

Level 1: Natural Barrier

Bovine Colostrum (400mg) — "nature's first vaccine." Contains immunoglobulins (IgG, IgA) and lactoferrin that strengthen the mucosal barrier — your body's first line of defense against pathogens.

The largest ingredient in the formula — 400mg per dose
⚔️

Level 2: Active Cellular Defense

Vitamin C (150mg) stimulates white blood cell production and activity. Quercetin (50mg) — the most powerful bioflavonoid — amplifies vitamin C's effect with anti-inflammatory properties. Zinc (25mg) is essential for T-cell function.

Vitamin C + Quercetin = proven synergy
🌱

Level 3: Support & Adaptation

Lion's Mane (50mg) — a medicinal mushroom that stimulates NGF production and modulates immune response. Selenized Brewer's Yeast (30mg) provides organic selenium. Vitamin D3 (50mcg) regulates 200+ genes involved in immunity.

Smart immunity — not just stronger, but more balanced

Active Ingredients

No fillers. Every milligram counts.

🧀 Bovine Colostrum 400mg
The cow's first secretion — a natural concentrate of IgG immunoglobulins, lactoferrin, growth factors, and antimicrobial peptides. Strengthens the intestinal mucosal barrier (where 70% of the immune system resides) and provides passive immunity.
🛡️ "Nature's first vaccine" — used medicinally for thousands of years
🍋 Vitamin C (Calcium Ascorbate) 150mg
Buffered form of vitamin C (calcium ascorbate) — gentler on the stomach than plain ascorbic acid. Stimulates white blood cell production, protects cells from oxidative stress, and accelerates tissue regeneration.
🍃 Quercetin 50mg
The most powerful natural bioflavonoid. Anti-inflammatory, antiviral, and antihistamine properties. Amplifies vitamin C's effect — together they form one of the most studied immune synergies in nutrition.
🧄 Lion's Mane (Hericium) 50mg
A medicinal mushroom with immunomodulatory properties — it doesn't just stimulate, it balances the immune response. Stimulates NGF production and contains beta-glucans that activate macrophages (pathogen-eating cells).
⚙️ Selenized Brewer's Yeast 30mg
Organic selenium source — an essential mineral for thyroid and immune system function. The selenized yeast form ensures superior absorption compared to inorganic selenite.
💪 Zinc Sulfate 25mg
Essential for the development and function of T-cells (lymphocytes that coordinate immune response). Zinc deficiency is one of the most common causes of weak immunity — affecting over 30% of the adult population.
☀️ Vitamin D3 50mcg
Cholecalciferol — the active form of vitamin D. Regulates 200+ genes involved in immune function. Studies show D3 deficiency increases the risk of respiratory infections by 40%. Especially essential during cold months.
⚠️ Up to 50% of Europeans are vitamin D deficient — especially in winter

Frequently Asked Questions

What makes Rootful Immunity different from other immune supplements? +
Most immune supplements contain only vitamin C and zinc. Rootful Immunity combines 7 active ingredients: 400mg bovine colostrum (rich in IgG immunoglobulins), vitamin C, quercetin, Lion Mane extract, selenium from selenized yeast, zinc, and vitamin D3. Four of these ingredients - Vitamin C, Zinc, Selenium, and Vitamin D - have EFSA-approved claims for immune function.
What is bovine colostrum and why is it in the formula? +
Colostrum is the first form of nutrition produced by mammals after birth. It is naturally rich in immunoglobulins (IgG), lactoferrin, and growth factors. Bovine colostrum has a similar profile to human colostrum and has been used for centuries in traditional medicine. We included 400mg per serving - the highest dose ingredient in the formula.
