Vitamin A, Your Immune System, and Measles

Vitamin A is critical for immune function, vision, and overall health. While most people associate it with eye health, it is a powerful support for boosting your immune system, which in turn allows for for disease prevention.  This is particularly true when it is sourced from whole foods

One of the best natural sources of vitamin A is ACP Complex by Doctor’s Research, a whole-food-based supplement that provides high-potency vitamin A in a safe and effective form. 

You might have heard about how vitamin A is essential for immune defense, but also to beware of toxicity – so where is the balance?

I’ll show you how ACP Complex differs from synthetic supplements, and how to take it for optimal prevention—especially against viral infections like measles.

What is Measles? Why is Vitamin A Important?

Measles is a contagious viral disease that spreads through respiratory droplets when an infected person coughs or sneezes. It causes high fever, cough, runny nose, red eyes, and a rash.

Why is Vitamin A Critical for Measles Prevention and Recovery?

• Prevents Severe Complications  Measles can weaken the immune system, leading to pneumonia, diarrhea, or blindness.
• Reduces Death Rates  Studies show vitamin A supplementation significantly lowers measles mortality, especially in malnourished children. (Malnourishment can be prevented with a healthy diet with a balance of vegetables, fruits, and protein.)
• Protects Mucosal Barriers  Vitamin A strengthens the mucosal linings in the lungs, gut, and eyes, reducing secondary infections.

Because vitamin A deficiency increases the risk of severe measles complications, the World Health Organization (WHO) considers high-dose vitamin A therapy as supportive for measles patients. (Check with your doctor for recommendations.)

With only one pill, ACP Complex offers immune resilience and viral protection.

Why Vitamin A is Essential for Immune Health

Vitamin A plays an important role in protecting your body from infections, especially viral illnesses like measles and respiratory infections. Here’s how:

Enhances Mucosal Barrier Function

The protective linings of the respiratory, digestive, and urinary tracts are protected.  These are your body’s first line of defense against pathogens.

Supports White Blood Cell Production

It boosts T-cell function and other immune cells that fight infections before they take hold.

Reduces the Severity of Viral Infections

Studies show vitamin A deficiency is linked to higher measles complications, including pneumonia, diarrhea, and blindness. High-dose supplementation has been proven to lower mortality rates in measles cases.

Protects Vision and Skin Health

Since vitamin A plays a role in cell repair and regeneration, it helps maintain healthy skin, reduce inflammation, and prevent eye-related issues.

Why Choose Whole Food Over Synthetic?

Most products contain synthetic vitamin A (retinyl palmitate or acetate), which lack important cofactors and can accumulate in the liver, leading to potential toxicity when taken in high doses.  The risk of toxicity from synthetic forms is why there is a warning on overdosing.

ACP Complex by Doctor’s Research is different because it is:
Whole-Food Based  Contains naturally sourced vitamin A with bioavailable co-nutrients.
Safer Than Synthetics The body utilizes whole-food vitamin A more efficiently, minimizing toxicity risk.
Contains Essential Cofactors Cofactors include Vitamin C and bioflavonoids, which enhance absorption and immune function.

Guideline for using ACP Complex for Prevention

This is a generalized guideline and is not a recommendation or prescription. Be sure to check with your doctor or medical provider to make sure it is right for you. 

To support immune health and prevent infections, ACP Complex can be used in a way that mimics the ancestral intake of vitamin A from whole foods like liver, butter, and cod liver oil.

Daily Preventative Dosage:

• 1 capsule every 1-3 days (provides 25,000 IU of vitamin A per capsule)
• Ideal for maintaining long-term immune function, eye and skin health

Immune-Boosting (During Cold & Flu Season):

• 1 capsule daily for 5-7 days when exposed to illness
• Helps strengthen mucosal immunity and fight off viral threats

Acute Infection Support (Short-Term Use):

• 1 capsule twice daily for 3-5 days (under professional guidance)
• Useful during periods of high viral exposure, travel, or stress

⚠️ Important: While ACP Complex provides a high-dose form of vitamin A, it is safe for short-term use due to its whole-food formulation. However, if taken continuously in high amounts, fat-soluble vitamins like A should be balanced with other fat-soluble vitamins (D, E, K2) and a nutrient-rich diet.

Whole-Food Sources of Vitamin A to Complement ACP Complex

For additional vitamin A from food, include:
🥩 Grass-Fed Liver  The best natural source of retinol (preformed vitamin A)
🐟 Cod Liver Oil  Provides both vitamins A and D in a natural balance
🧈 Grass-Fed Butter   A great way to support fat-soluble vitamin absorption
🥚 Pasture-Raised Eggs  A convenient source of retinol and healthy fats
🥕 Carrots & Sweet Potatoes   Rich in beta-carotene, a precursor to vitamin A
