It’s allergy season and as much as you’d like to go outside and smell the flowers, spring paints a different picture for you.

Sneezing, nasal congestion, runny nose, and the usual leave their mark on you during this crisp season. 

If allergy medications have been your staple and you’re looking for alternatives aside from the usual over-the-counter antihistamines, Natural D-Hist is the answer.

Natural D-Hist is an effective and powerful blend of natural ingredients designed to provide you with comprehensive support for these seasonal challenges and relieve you of your allergy symptoms.

Here’s another good thing: aside from enhancing your respiratory health, this all-natural supplement carries additional benefits as it also supports your cardiovascular and cognitive health.

Let’s take a closer look at Natural D-Hist, its main uses and a wide range of benefits.

Natural D-Hist 

Did you know? Ortho Molecular’s Natural D-Hist has become a favorite health supplement for seasonal allergy support because of its effectiveness. Here’s how it works:

Natural D-Hist Uses

1 – Reduces Allergy Symptoms

If you find yourself frequently visiting online pollen tracking sites such as or National Allergy Bureau in anticipation of respiratory irritation, you may want to get Natural D-Hist to prepare for these seasonal challenges.

Natural D-Hist is used to reduce seasonal allergy symptoms caused by common environmental allergens.

These symptoms may include:

  • Sneezing
  • Sniffling
  • Runny nose
  • Watery or itchy eyes
  • Itchy or tickly throat
  • Itchy ear or ear congestion
  • Itchy sinuses
  • Post-nasal drip

Fact: Histamine is the chemical component in your body that triggers your allergic reactions. Your regular anti-histamine medications work by blocking the histamine receptors to alleviate your symptoms. Natural D-Hist works differently

This all-natural supplement stabilizes your mast cells to prevent the release of histamine into your body, consequently resulting in reduced symptoms. This can be attributed to Natural D-Hist’s powerful blend of natural ingredients which include :

Thus, you get to experience comfort and relief from your allergies and can get the most out of this season.

Also, if you find your little ones struggling with allergies and respiratory irritation, D-Hist Jr. is available and formulated to help kids combat these seasonal challenges, too.

2 – Clears Nasal and Sinus Passageways

Your sinuses (the hollow regions between your eyes and behind your forehead) produce mucus.

Mucus has an important function as it moistens your nostrils to protect you from dust and irritants.

However, once your body starts acting up due to allergens, your sinuses produce excessive mucus, leading to inflammation or swelling.

One of Natural D-Hist’s key components—N-Acetyl Cysteine (NAC)—helps your body produce Glutathione

NAC and Glutathione both help make your mucus less viscous. This consequently enables you to breathe more easily and provides relief by clearing your nasal and sinus passageways [8].

3 – Supports Immune Balance

A properly functioning immune system is a balance between fighting off bad elements and tolerating harmless elements invading your body.

Allergies happen because your body overreacts to a harmless element [9].

Natural D-Hist’s key ingredients (Quercetin, Bromelain, and Stinging Nettles Leaf) help you achieve immune balance by modulating and adjusting your body’s immune responses [1, 2, 3, 4, 5].

This leads to an immune balance that enables your body to protect you from diseases, allowing it to tolerate harmless triggers without producing unnecessary immune responses [10].

Now, let’s delve into the numerous benefits of this powerful supplement for your health and wellness.

1 – Provides Allergy Relief Without the Unwanted Side Effects

Although you may get relief from your usual anti-histamines, you’ll likely get side effects which include [11]:

  • Drowsiness
  • Reduced coordination, reaction speed, and judgement
  • Dry mouth
  • Headache

Due to this, your productivity suffers as you try to cope with seasonal challenges.

By taking Natural D-Hist, you relieve yourself from your allergy symptoms without unwanted side effects.

Likewise, if you’re looking for an all-natural relief for a scratchy throat, Biocidin Throat Spray is recommended.

2 – Improves Respiratory Health 

By boosting Glutathione levels in your body, one of Natural D-Hist’s key ingredients, N-Acetyl Cysteine (NAC), helps improve your respiratory health. 

Fact: Both NAC and Glutathione have anti-oxidant properties that help reduce inflammation and oxidative stress. 

In addition, NAC helps relieve symptoms of other respiratory health conditions such as bronchitis, COPD (Chronic Obstructive Pulmonary Disease), cystic fibrosis, asthma, and pulmonary fibrosis [12].

3 – Helps Reduce Inflammation

Natural D-Hist is a powerful blend of anti-inflammatory and anti-oxidants which help fight inflammation.

Let’s explore this further.

Our body’s normal biological processes produce free radicals and antioxidants. Ideally, there should be a balance between these two components. 

But when our bodies are subjected to stress, it produces even more free radicals. 

When the antioxidants in our bodies are insufficient to counteract these free radicals, it leads to an imbalance between the two and results in oxidative stress

This oxidative stress then leads to oxidative damage (cell damage) and inflammation.

Remember, inflammation is a vital defense process that our bodies need for healing. However, persistent inflammation harms our bodies as it paves the way to chronic diseases [12].

While it is always best to get antioxidant and anti-inflammatory compounds from food sources, there may be times when we might not get enough. This is when taking these dietary supplements becomes beneficial.

Take a look at Natural D-Hist’s formulation as it possesses both antioxidant and anti-inflammatory properties [1, 3, 5, 8, 13, 14, 15]:

  • Quercetin
  • Stinging Nettles Leaf
  • Bromelain 
  • N-Acetyl Cysteine 
  • Vitamin C

Take advantage of all the beneficial properties of this all-natural dietary supplement for your overall health and wellness.

4 – Helps Support Cardiovascular Health

Natural D-Hist’s array of botanicals may also be helpful for your heart.

Quercetin has been linked to positive effects on cardiovascular diseases such as hypertension, atherosclerosis, ischemia-reperfusion injury and cardiotoxicity [16].

Stinging Nettles Leaf also benefits cardiovascular health due to its anti-hypertensive effect [3].

Bromelain, as shown by studies, may also reduce symptoms of several cardiovascular diseases and shows great potential in the treatment of various heart ailments [5].

5 – May Support Brain or Cognitive Function

In addition to addressing respiratory and allergy symptoms, Natural D-Hist may also aid your brain or cognitive function.

Relative to the aging process, Quercetin is beneficial as it can reverse cognitive impairment and help in memory improvement [16].

In addition, Quercetin helps prevent dementia and other neurodegenerative diseases by reducing oxidative and inflammatory damage in the brain [17].

Likewise, N-Acetyl Cysteine has the potential to be considered as an additional treatment to conventional therapy in treating degenerative brain disorders such as Parkinson’s Disease, Alzheimer’s Disease, neuropathic pain and stroke [18].

Natural D-Hist Recommended Dosage

Loading Dose2 capsules three times per day for 7-10 days or as recommended by your health care professional
Maintenance2 or more capsules per day or as recommended by your health care professional

Important: Natural D-Hist does not contain gluten, yeast, artificial colors or flavors.

Warning: If pregnant or nursing, consult a healthcare professional before taking this product.

Follow your health care professional’s recommendation, as excessive intake may have adverse side effects.

In the Case of Bromelain Allergy

Bromelain enhances the absorption of Quercetin and has been added to Natural D-Hist to maximize its full effects on your body. 

However, Bromelain may cause allergic reactions, especially for those with pineapple allergies (as this is a powerful antioxidant in this fruit). 

With that said, you may use Pure Encapsulations Quercetin instead to relieve your allergy symptoms.
