Sick of colds? Not anymore.


Protect yourself from recurring sickness with Immune Defense, our natural immune system supplements. Taken twice daily, this vitamin and mineral-packed herbal formula promotes immune system health and strengthens your body’s resistance to common colds and the flu. Feel your best year-round with this preservative-free, doctor-formulated herbal immune support formula.

What It Does
  • Promotes a strong immune defensive system
  • Cleanses the body from allergens & impurities
  • Supports respiratory health
  • Rich in Vitamins B, C, & Minerals
  • May help protect against autoimmune diseases, the common cold, and the flu
How It Works
  • Our immune system is our body's natural defense against illness, but it declines as we age. Immune responses slow down as we get older, making it harder to fight infections.
  • Immune Defense is designed to support and strengthen the immune system without overstimulation.
  • Unlike synthetic immune boosters, this all-natural, herbal blend provides sustainable immune support.
  • Strengthens natural defenses while maintaining immune system stability.
Who It's Good For
  • Teachers and childcare workers – Regular exposure to children increases the risk of illness.
  • Frequent travelers – Airplanes, public transportation, and crowded spaces expose individuals to higher concentrations of bacteria and viruses.
  • Parents of school-aged children – Children bring home germs from school and daycare, increasing the likelihood of illness within households.
  • Healthcare and frontline workers – Daily contact with sick individuals requires strengthened immunity.
  • Immunocompromised individuals – Those with weakened immune systems require additional support.
  • Older adults – Age-related immune decline makes infections more difficult to fight off.

Immune Defense is recommended for ages 12 and older.

How to Take
  • Take two capsules two times a day
  • If you suffer from severe symptoms, take 2 capsules 3 times a day
  • If you are sensitive, start with 1 capsule once a day & gradually increase to 2 capsules 2-3 times a day
  • Wait at least 30 minutes or more before or after a meal
  • Capsules may be added to light veggie or fruit smoothies (powder or whole capsule)

CAUTION: If pregnant or nursing, please consult a physician prior to use. KEEP OUT OF REACH OF CHILDREN.

Magic!

I woke up with a scratchy throat and feeling under the weather. I took 3 capsules of Immune Defense 3 times a day per Dr. Liu’s recommendation, and the next day, I was completely healed!

Best for flu season

So far after using immune defense. I’ve felt the best I have this whole flu season. I work with the public a lot (as a registered nurse) so I get sick often. This product has definitely helped boost my immune system!

Keeps me and my kiddo healthy

My son would frequently get sick, every time he would get sick I would too. Ever since we started taking this, we rarely ever get sick. Sol Nutrtion works great for kids too!
