What other names is Humic Acid known by?

Acide Humique, Ácidos Húmicos, Extracto de Húmicos, Extrait d'Humique, Humate, Humic Extract.

What is Humic Acid?

Humic acid is a chemical produced by decaying plants. People use it to make medicine.

People take humic acid for stimulating the immune system and treating the flu (influenza), avian flu, swine flu, and other viral infections.

Insufficient Evidence to Rate Effectiveness for...

  • Stimulating the immune system.
  • Treating viral diseases.
  • Other conditions.
More evidence is needed to rate the effectiveness of humic acid for these uses.

How does Humic Acid work?

There isn't enough information available to know how humic acid works.

Are there safety concerns?

There isn't enough information available to know if humic acid is safe. Laboratory research and population research has associated humic acid with joint disease, circulatory disease, and thyroid disease.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Not enough is known about the use of humic acid during pregnancy and breast-feeding. Stay on the safe side and avoid use.

“Auto-immune diseases” such as multiple sclerosis (MS), lupus (systemic lupus erythematosus, SLE), rheumatoid arthritis (RA), or other conditions: Humic acid might cause the immune system to become more active, and this could increase the symptoms of auto-immune diseases. If you have one of these conditions, it's best to avoid using humic acid.

Dosing considerations for Humic Acid.

The appropriate dose of humic acid depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for humic acid. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
