Frequently Asked Questions

What is the Defender System?

The Defender System is our complete product line designed to work together for comprehensive allergen and wellness support. It's not a bundle you must buy all at once—it's a framework showing how our products complement each other. You can start with any single product and add others as needed. The system includes environmental sprays for your living space, oral supplements for internal support, and topical magnesium for recovery and rest.

What products are in the Defender System?

  • Allergy Asthma Clean Allergen Spray by Allergy Defender (Environmental spray) - Reduces allergens on surfaces and in air
  • EnviroDefender (Oral supplement) - Supports balanced immune response to environmental triggers
  • HistaDefender DAO (Oral supplement) - Supports natural histamine breakdown in the gut
  • DetoxDefender (Oral supplement) - Phase 1 & Phase 2 detox support
  • Magnesium Topical Spray (Topical application) - Supports muscle relaxation, stress reduction, and sleep
  • Wellness Bundle - Allergen Spray plus Magnesium Topical Spray

How do these products work together?

Think of it as defense from multiple angles. The Allergen Spray reduces what's in your environment—the pet dander floating in the air, cat dander on your couch, dust mites in your carpet. EnviroDefender, DetoxDefender and HistaDefender work from the inside, supporting how your body responds to environmental triggers and processes histamine plus the detox phase. Magnesium addresses the physical toll that stress, poor sleep, and muscle tension take on your body. You can use one product alone or combine them based on what you're dealing with.

Allergen Spray

What does it do?

Reduces up to 99% of allergens on surfaces and up to 95% of allergens in the air. When you spray it, the minerals attract and attach to allergen molecules (pet dander, dust mites, household dust and more), surround them, and dehydrate them. This creates a protective barrier that prevents allergens from becoming airborne again.

What's in it?

100% minerals: FDA & GRAS pure sodium sesquicarbonate and FDA food grade mineral phosphate salts. The same minerals found in foods like dairy and meat, and used in water softening. No plant extracts, enzymes, zeolite, petroleum, essential oils, harsh chemicals, or fragrances. Completely unscented and hypoallergenic.

Available sizes:

  • Standard spray: 33.8 oz (easy-to-use bottle with mineral concentrate)
  • Large bundle: 67 oz (bottle + one refill packet)
  • Extra large bundle: 100+ oz (bottle + two refill packets)
  • Refill 2-pack: 64 oz total (two mineral concentrate packets)
  • Refill 4-pack: 128 oz total (four mineral concentrate packets)

How to use:

For the bottles: Fill with tap water (or any water you feel comfortable using) shake until dissolved, and spray in the air and on surfaces. Respray as needed to ensure your continued comfort.

For the Refill Packets: Pour one mineral packet into a clean 32-33 oz spray bottle, fill with tap water, shake until dissolved, and spray in the air and on surfaces. Respray as needed to ensure your continued comfort.

Where can you use it?

In the air (unlike other products which are only surfaces). Upholstery, sofas, carpets, rugs, bedding, mattresses, pet beds, curtains, cushions—any fabric surface where allergens settle. Spray both in the air and directly on surfaces.

Safety:

This formula was created by a family, for families. We made sure it contains zero harsh chemicals, fragrances, or irritants that could bother you or your pets. Safe for the whole household—furry members included—because we wouldn't use anything in our home that we wouldn't trust in yours.

Why it works:

Minerals contain zero proteins, and proteins are what cause allergic reactions. This is the only allergen spray on the market you can spray in the air—not just on surfaces.

EnviroDefender (Oral Supplement)

What does it do?

Supports your body's balanced immune response to environmental triggers like pollen, dust, mold, and pet dander. Instead of just masking discomfort after it starts, EnviroDefender works proactively—supporting your system before triggers become a problem. It works on multiple phases of histamine in the body: production, release, and degradation.

What's in it?

Premium, carefully sourced ingredients backed by scientific research:

  • Quercetin: Helps slow histamine release and supports eye comfort (studied for seasonal discomfort)
  • Bromelain: Natural enzyme that supports digestion and reduces occasional inflammation
  • Nettle extract: Inhibits mast cells and acts against histamine receptors; provides nasal comfort
  • NAC (N-Acetyl Cysteine): Supports respiratory health
  • Boswellia: Blocks the 5-LOX pathway involved in immune overreactions
  • Grapeseed extract: Inhibits histidine decarboxylase (enzyme responsible for histamine production)
  • Vitamin C (ascorbic acid): Helps break down histamine that's already been released
  • Vitamin D3: Supports immune system balance
  • Zinc: Essential for immune function
  • Bioflavonoids: Antioxidants that enhance vitamin C effectiveness

Allergen information:

Free from soy, wheat, fish, milk, shellfish, peanuts, and tree nuts.

Available sizes:

EnviroDefender 120 capsules, and travel size 16 capsules

Cost:

Under $2 per day for powerful support

How it compares:

Most products address discomfort after it happens. EnviroDefender takes a different approach—it supports your body's natural ability to handle environmental triggers proactively, so you're prepared before triggers show up.

HistaDefender DAO (Oral Supplement)

What does it do?

Supports your body's natural histamine balance by providing DAO (diamine oxidase), the key enzyme responsible for breaking down histamine in the digestive tract. The gut plays a central role in histamine regulation—when your gut is overwhelmed or out of balance, histamine can build up, making your body more reactive to environmental triggers.

What is histamine intolerance?

Histamine intolerance happens when your body has more histamine than it can break down. This can come from high-histamine foods, gut imbalances, stress, or overactive mast cells. Without enough DAO enzyme, histamine builds up, causing bloating, brain fog, skin reactions, and general discomfort.

What's in it?

Premium ingredients designed to support histamine breakdown:

  • DAO enzyme (diamine oxidase from porcine kidney extract, 30,000 HDU): Breaks down histamine in the digestive system, especially useful before meals with high-histamine foods
  • Maritime Pine bark extract (95% proanthocyanidins): Supports balanced histamine levels and gut health with antioxidant properties
  • Catalase enzyme: Protects against oxidative stress by breaking down hydrogen peroxide, reduces inflammation
  • Vitamin C (ascorbyl palmitate): Fat-soluble form for better absorption; helps regulate histamine levels and enhances natural histamine breakdown

Allergen information:

Free from eggs, milk, shellfish, fish, peanuts, wheat, tree nuts, and soy.

Available sizes:

HistaDefender 60 capsules, and travel size 12 capsules

How to use:

Take one capsules one or two times a day. The DAO enzyme helps your body process dietary histamine more efficiently.

Who it's for:

People experiencing histamine sensitivity symptoms related to food, gut imbalances, or general reactivity to everyday triggers. Especially helpful for those who notice discomfort from certain foods or who suspect gut-related issues.

Magnesium Topical Spray

What does it do?

Delivers magnesium chloride directly through your skin, bypassing the digestive system for efficient absorption. Supports over 700-800 enzymatic functions in the body. Most commonly used for muscle relaxation, stress reduction, and promoting restful sleep. Can also be used for post-workout recovery, reducing muscle cramps, and as a natural deodorant.

Why topical instead of pills?

Topical application (transdermal absorption) bypasses the digestive system entirely. If you have stomach issues or digestive problems, oral magnesium can be hard to absorb. Applying it to your skin ensures the mineral reaches your bloodstream. It also allows for targeted application to specific areas like sore muscles.

What's in it?

100% pharmaceutical grade magnesium chloride (USP grade). No fragrances, harsh chemicals, or added scents. Just pure magnesium.

Available sizes:

  • Magnesium 4 oz
  • Magnesium 12 oz (Extra Strength)

Concentration:

45mg magnesium per spray. You can adjust concentration by adding more or less water to the bottle based on your comfort level.

How to use:

The spray comes with magnesium crystals. Fill the bottle to the top with water, shake until crystals dissolve, then spray on clean skin. Apply 5-10 sprays to stomach, feet, arms, or any sore areas. Rub in and let air dry. For sleep: spray before bed on stomach or feet. For muscle recovery: spray after workouts on affected areas. For stress: use during the day on stomach or arms.

Common side effects:

Itching or tingling sensation when first applied—this is normal and indicates magnesium deficiency. The sensation should subside with regular use. If uncomfortable, rinse the area with water after 20 minutes (this still allows time for absorption). Start with feet if you're sensitive, as they tend to be less reactive.

Where to apply:

The soles of your feet have large pores ideal for absorption. Stomach, arms, legs, and back also work well. Avoid freshly shaved areas (wait at least 12 hours) and sensitive areas.

Best for:

Sleep support, muscle relaxation and recovery, stress reduction, restless legs, muscle cramps, anxiety support. Can be used as natural deodorant (2-3 sprays under each arm on clean, dry skin).

Safety:

Safe for most people. Caution advised for those with kidney disease or on certain medications (antibiotics, heart medications). Consult your doctor if taking regular medications or if you have impaired kidney function.

The Story Behind Allergy Defender

Why we started:

Founder nearly died from an allergy-induced asthma attack at age five. Her father Chris, a chemist, formulated a natural mineral-based solution that gave her life back. Now the family helps over 250,000 families manage their allergens and wellness.

Our approach:

Science-backed, all-natural solutions. We believe in truly helping people—because we know first hand what it's like having allergies and asthma. We prioritize effectiveness and safety for the whole family, including pets.

Our commitment:

We donate to homeless coalitions where transitional housing triggers asthma in children. We contribute to animal shelters to help decrease pet surrenders due to allergies.

Questions We Get All the Time

Is this better than an air purifier?

Different tools for different jobs. Air purifiers filter what passes through them. Our Allergy Asthma Clean Allergen Spray by Allergy Defender treats the air and surfaces. Many customers use both together for maximum control.

Can I use this with my current medications?

Allergen Spray is topical environmental treatment—no interactions. For supplements, always check with your doctor, especially if you're taking medications or have existing conditions.

Will this cure my allergies?

These products don't cure allergies. They reduce environmental allergen load (spray) and support your body's natural processes (supplements). Allergy management is a comprehensive system that includes multiple approaches: reducing triggers, supporting your body, maintaining clean spaces, and working with your healthcare provider.

What if it doesn't work for me?

We offer a 30-day risk-free guarantee. If you're not satisfied, contact us. We'll help you troubleshoot your approach (application frequency, usage, environmental factors) and handle returns according to our policy.
