A day in the life
How 1000 mg of Vitamin C moves through your day
One capsule taken after your morning meal sets off a sequence of support that carries through focus, energy, and immune readiness. Here is what that looks like across a typical day.
Standard routine
C ImmunoProtect
7:00
💊
Capsule taken
One capsule with breakfast. The daily ritual starts.
10:00
🛡️

L-ascorbic acid absorbed, immune defence begins its work.
12:00

Energy steadier
Less fatigue, more focus through the midday stretch.
15:00

Recovery supported
Collagen signals and iron absorption working quietly in the background.
Hero ingredient
L-Ascorbic Acid 1000 mg
Pure Vitamin C at 1000 mg per capsule, the clinically recognised form your immune system relies on to fight infection, protect cells, and keep energy stable.
L-ascorbic acid is the bioavailable form of Vitamin C that the body absorbs and uses directly. At 1000 mg per capsule, C ImmunoProtect delivers a meaningful daily dose that supports the immune system, aids normal collagen synthesis across multiple tissues, reduces tiredness, and contributes to the protection of cells from oxidative stress.
1000 mg per capsule
Double the dose found in most standard daily Vitamin C supplements.
Pure L-ascorbic acid
The direct bioavailable form, absorbed and used by the body without conversion.
Multi-tissue collagen support
Promotes normal collagen formation for skin, bones, cartilage, gums, and blood vessels.
Zero sugar, clean capsule
No added sugar, no unnecessary additives in the formula.
The Mechanism
The Double-Dose Immune Support Cycle
1
Take
One capsule after a meal with a glass of water. No new routine required.
2
Absorb
L-ascorbic acid is rapidly absorbed from the gut into the bloodstream at full 1000 mg dose.
3
Activate
Vitamin C signals immune cells, neutralises free radicals, and supports normal collagen synthesis.
4
Protect
Daily antioxidant coverage builds over time, reducing tiredness and supporting seasonal resilience.
One capsule after a meal starts a four-stage cycle: absorption, immune activation, cell protection, and tissue repair support. The result is steadier daily defence, less fatigue, and a body that is better prepared when seasonal threats arrive.
The Science
Why your immune system struggles without enough Vitamin C
Low or inconsistent Vitamin C intake leaves four key systems under-supported. C ImmunoProtect addresses each one with a single high-dose daily capsule.
01
Depleted immune reserves
Vitamin C is consumed rapidly by immune cells during infections. Low daily intake means those reserves run out exactly when your body needs them most.
02
Unchecked oxidative stress
Without adequate antioxidant input, free radicals accumulate and damage healthy cells, accelerating fatigue and weakening the body's repair capacity over time.
03
Slow collagen turnover
Vitamin C is essential for normal collagen synthesis. Insufficient intake means slower tissue repair across skin, gums, cartilage, and blood vessels.
04
Reduced iron absorption
Non-haem iron from plant-based foods requires Vitamin C to convert into an absorbable form. Low Vitamin C directly limits how much iron your diet delivers.
Key ingredients
Key ingredients
C ImmunoProtect is built around one high-dose active ingredient: 1000 mg of L-ascorbic acid per capsule. The remaining ingredients are functional excipients that ensure capsule integrity and consistent delivery. No sugar, no fillers beyond what the formulation requires.
1000 mg
Vitamin C (L-ascorbic acid)
High-dose immune and cell support
At 1000 mg per capsule, L-ascorbic acid supports the immune system, protects cells from oxidative stress, promotes normal collagen formation across skin, bones, cartilage, gums, teeth, and blood vessels, and helps reduce tiredness and fatigue.
Hydroxypropyl Methylcellulose
Capsule shell
A plant-derived polymer used to form the capsule shell, providing a clean, vegetarian-friendly delivery format with no animal-derived components.
Microcrystalline Cellulose
Bulking agent
A natural bulking agent derived from cellulose that gives the capsule its proper fill weight without contributing unnecessary additives or calories to the formulation.
Magnesium Salts of Fatty Acids
Anti-caking agent
An anti-caking agent that keeps the powder inside the capsule free-flowing and consistent from the first to the last capsule in the pack.

L-ascorbic acid plays a key role in the function of immune cells, acting as a cofactor that supports their activity during infection. It also functions as a powerful antioxidant that neutralises free radicals, protecting cells from oxidative damage. Daily intake helps maintain these immune reserves, particularly important during seasonal illness periods.
No. C ImmunoProtect contains zero sugar and no unhealthy additives. The only non-active ingredients are a plant-derived capsule shell made from hydroxypropyl methylcellulose, microcrystalline cellulose as a bulking agent, and magnesium salts of fatty acids as an anti-caking agent.
