2. A Visible Bounce-Back
for Thousands of Flocks
Keepers tell me the change shows at feed time first: more energy, combs with color again, and more eggs in the box than the week before.
Virginia R. on Immunity Booster:
"After adding Immunity Booster to my waterer, my Easter Egger has been laying an egg every day for the last week!"

Erika K. on Immunity Booster:
"We saw the difference in a just a few days!"

3. Four Natural Ingredients,
Double Concentrated

Every ingredient is named on the label and measured into one capful. One 16 oz bottle makes 16 gallons. Made in New Mexico with US-sourced ingredients.

Omega-3 (flaxseed oil)

Oregano oil

Turmeric

Vitamins D3, D and E

4. Visible Changes in
Just a Few Weeks

Most keepers notice the first changes within a few weeks. The most common mistake is stopping too soon, so keep it in the water every day.
