    Formula I - Helping me stay healthy since Shaklee first introduced it.
    Formula I is easy to swallow with a small glass of water. There are no bad side effect, only good ones!

    I really like Formula I.
    When I added Formula I to several other immunity products, my immune system got stronger. Don’t ever stop making Formula I. I take it all year around now.
