For the strength you can’t see

Gut & Immunity

2 products · 30-day routine

Your gut is where immunity begins.*

Your gut lining is one of your immune system’s busiest places, home to about 80% of the body’s antibody-making cells. This protocol supports both: four studied probiotic strains with prebiotic fiber for your gut bacteria, and colostrum with 575 mg of IgG for the gut lining and immune health.*

Your ritual

For the strength you can’t see

  1. Stir one scoop of colostrum into cold water and drink it within 10 minutes.
  2. Take one probiotic with a daytime meal and one with dinner.
  3. Keep both bottles where you eat.

Three small steps for the work you can’t see.

The moment is when you take it. The evidence is below.

You know your days best. We bring the evidence.

Your day, in 2 steps

Each product has its own time of day, so you always know what to take and when.

  1. Day and evening

    Probiotic 40 Billion

    1 capsule by day, 1 in the evening.

  2. Morning

    Colostrum Powder

    1 scoop in cold water or a smoothie.

Why they work together

Probiotics add beneficial bacteria; colostrum supplies immunoglobulins (IgG) and growth factors that support the gut lining they live on. Our probiotic names every strain (La-14, Bl-04, Lp-115, Lpc-37), so you can look each one up.*

Reviews

New, so no reviews yet

Here is what you can check instead. Every claim on each product’s page has an evidence grade and a link to the study behind it. We won’t fill this space with borrowed praise.

We started Cellovi because shopping for supplements meant wading through big promises, hidden doses and claims with no study in sight. So we built the brand we wanted to buy from.

Your reviews come next, and we’ll read every one.

The Cellovi team
