ABOUT IMMUNE-BOOSTING ANTIOXIDANTS

The immune system generates and encounters reactive molecules as part of normal metabolism and immune activity. Antioxidants help maintain the body’s natural defenses against oxidative stress, supporting cellular integrity and normal immune function.

Our Immune-Boosting Antioxidants collection at Coal Harbour Pharmacy features pharmacist-curated vitamins, minerals, amino-acid derivatives, botanical extracts, and combination formulas designed to complement everyday immune and antioxidant support.

Rather than simply “boosting” immunity, these nutrients help support a healthy, appropriately regulated immune response while contributing to the body’s antioxidant defense systems.

KEY BENEFITS

• Helps protect cells against oxidative stress

• Supports normal immune-system function

• Provides nutrients involved in antioxidant defense

• Supports cellular protection and recovery

• Helps maintain healthy inflammatory balance

• Supports glutathione and endogenous antioxidant pathways

• Provides additional nutritional support during periods of increased demand

• Complements everyday immune-health routines

WHO IT’S IDEAL FOR

This collection may be useful for:

• Adults seeking daily antioxidant and immune support

• Individuals with increased nutritional demands

• People looking for seasonal wellness support

• Active individuals experiencing greater physical demands

• Older adults focused on healthy aging and immune resilience

• Individuals seeking targeted antioxidant supplementation

• People looking to complement a nutrient-dense diet

Children should use only products specifically formulated and dosed for their age.

WHAT ARE ANTIOXIDANTS?

Antioxidants are substances that help neutralize or control reactive molecules known as free radicals.

Free radicals are naturally produced through processes such as:

• Cellular metabolism

• Exercise

• Immune activity

• Exposure to environmental stressors

When free-radical production exceeds the body’s antioxidant defenses, oxidative stress can occur.

The body has its own sophisticated antioxidant systems, supported by dietary nutrients and compounds obtained from foods and supplements.

HOW ANTIOXIDANTS SUPPORT IMMUNE HEALTH

Normal immune activity and oxidative processes are closely connected.

Antioxidant nutrients can contribute to immune health by helping:

• Protect cellular components from oxidative damage

• Maintain normal immune-cell function

• Support antioxidant enzyme systems

• Maintain tissue integrity

• Support cellular recovery

• Maintain appropriate inflammatory and immune responses

Importantly, free radicals also perform useful biological functions. The goal of antioxidant nutrition is therefore balance, not eliminating all oxidative activity.

KEY ANTIOXIDANTS IN THIS COLLECTION

Vitamin C

Vitamin C is an essential water-soluble vitamin with antioxidant activity and an established role in normal immune function.

It contributes to:

• Normal immune-system function

• Protection of cells against oxidative stress

• Collagen formation

• Wound healing

• Regeneration of other antioxidants

Vitamin C is available in capsules, tablets, powders, chewables, gummies, and liquid formulations.

Selenium

Selenium is an essential trace mineral required for the activity of several antioxidant enzymes.

It supports:

• Normal immune function

• Protection against oxidative stress

• Normal thyroid function

• Antioxidant enzyme activity

Because selenium is required only in relatively small quantities, avoid unnecessarily high-dose supplementation.

Quercetin

Quercetin is a naturally occurring flavonoid found in foods such as onions, apples, berries, and leafy vegetables.

It is commonly included in antioxidant and seasonal wellness formulas because of its:

• Antioxidant activity

• Role in cellular protection

• Relationship with inflammatory signaling pathways

• Frequent pairing with vitamin C and other flavonoids

N-Acetylcysteine (NAC)

NAC is a derivative of the amino acid cysteine and serves as a precursor used by the body to produce glutathione, an important endogenous antioxidant.

NAC is commonly used in nutritional formulas designed to support:

• Glutathione production

• Antioxidant defenses

• Cellular protection

• Respiratory health

Its suitability can depend on medications and medical conditions, so professional guidance may be appropriate.

Elderberry

Elderberry (Sambucus nigra) contains naturally occurring anthocyanins and other polyphenolic compounds.

It is commonly found in seasonal wellness products such as:

• Syrups

• Gummies

• Lozenges

• Capsules

• Liquid extracts

Elderberry should be considered supportive nutrition rather than a substitute for vaccination or treatment of an infection.

Green Tea Extract

Green tea contains polyphenols, including catechins such as EGCG.

These compounds provide antioxidant activity and are commonly incorporated into formulas supporting:

• Cellular antioxidant protection

• Cardiovascular wellness

• Metabolic health

• Healthy aging

• General wellness

Concentrated green tea extracts differ significantly from brewed tea and should be used according to product directions.

OTHER ANTIOXIDANTS YOU MAY FIND

Depending on available products, this collection may also include:

• Glutathione

• Alpha-lipoic acid

• Vitamin E

• Zinc

FAQ

What are the best antioxidants for immune support?
Vitamin C and selenium have established physiological roles in normal immune function and antioxidant protection. Other compounds such as quercetin, NAC, elderberry polyphenols, and green tea catechins are commonly incorporated into antioxidant wellness formulas.

Do antioxidants prevent colds or flu?
Antioxidant supplements cannot guarantee prevention of respiratory infections. Adequate nutrition supports normal immune function, but supplements should complement—not replace—vaccination, hygiene, sleep, and appropriate healthcare.

What is the connection between NAC and glutathione?
NAC supplies cysteine, one of the amino acids the body uses to synthesize glutathione.

Can I take vitamin C, selenium and quercetin together?
These nutrients are found together in some combination products. Check the total amounts from all supplements and avoid exceeding recommended intake.

Are antioxidant supplements suitable for children?
Some are, but children should use age-appropriate products and doses. Adult antioxidant formulas should not automatically be given to children.

Is taking more antioxidants better?
No. High doses are not necessarily more beneficial, and excessive intake of certain antioxidants, vitamins, or minerals may cause adverse effects.

Can antioxidants replace fruits and vegetables?
No. Whole foods provide fibre, vitamins, minerals, phytonutrients, and many other beneficial compounds that isolated supplements cannot fully reproduce.

CAUTIONS & WARNINGS

Consult a healthcare professional before using concentrated antioxidant supplements if you:

• Are pregnant or breastfeeding

• Take prescription medications

• Have kidney or liver disease

• Have an autoimmune condition

• Are undergoing chemotherapy or radiation therapy

• Take anticoagulant or antiplatelet medications

• Are preparing for surgery

• Are considering supplementation for a child

Avoid unnecessarily high doses or combining multiple formulas containing the same nutrients.

Antioxidant and immune-support supplements are not substitutes for vaccines, prescribed medications, or appropriate medical treatment.
