OMRI Listed, and beeswax — not paraffin.

Most calcium boluses on the market are coated in paraffin wax, a petroleum product. Ours is coated in beeswax. That is what lets it carry the OMRI listing your organic certifier is going to ask about, and it is the reason organic dairies come to us in the first place.

What you get

  • OMRI Listed — certified for organic dairy operations
  • Beeswax coated, not paraffin wax like most competitors
  • 44 grams of highly absorbable calcium chloride per bolus
  • Calcium completely available within 30 minutes
  • Acidifies cows to promote calcium resorption from bones
  • No fillers, no extras. Made in the U.S.A.

How to use it

Give one bolus immediately after she calves, then a second 12 to 24 hours later, using the No B.S. stainless steel applicator. Each bolus delivers 44 grams of supplemental calcium, completely available within 30 minutes.

The charts.

Serum calcium, measured. Tap a chart to enlarge it and drag around — or send this page to your vet or nutritionist.

  • Two study graphs. Left: serum calcium falls sharply at calving. Right: serum calcium after a bolus stays higher over 24 hours with No B.S. calcium chloride than with the market-leader bolus.

    Drag to look around

    Same calcium chloride, same science as our conventional bolus — the organic version is beeswax coated and OMRI Listed. A single calcium-chloride source raised serum calcium faster and held it higher over 24 hours than the market leader.

From a customer

Straight from the dairy.

“No B.S. calcium boluses have been an important part of our fresh cow program for several years. We're very satisfied with how they perform.”
Hank DeVries
manager, Cal Poly Dairy Unit · San Luis Obispo, CA

Conventional herd?

If you are not certified organic, the standard No B.S. Calcium Bolus™ is the same calcium at $5.00 a bolus, or $4.50 by the pallet.

Questions

Straight answers.

Is there an organic option?

Yes. The No B.S. O-Calcium Bolus™ is OMRI Listed for certified organic dairy operations, and it is beeswax coated rather than paraffin wax like most competitors. Same 44 grams of calcium chloride, same 30-minute availability.

How many boluses, and when?

Two boluses, spaced apart. Give one immediately after she calves, then a second 12 to 24 hours later, using the No B.S. stainless steel applicator. The first one covers the calcium crash at calving; the second carries her through the day after, which is where a single dose runs out.

What is actually in it?

44 grams of highly absorbable calcium chloride per bolus, coated so it is safe on the cow's throat going down. No fillers, no extras. Made in the U.S.A. That is the whole ingredient conversation.

What does shipping cost, and how fast?

Shipping is free on every order, every time — packs and pallets both. Orders ship directly to your dairy. Pallets move by freight, also free.

Do I have to use your gun?

No. These work with any standard bolus gun you already have. If you want ours, your first bolus order includes one free — it is applied at checkout, you don't need a code — and pallet orders include three.

What are the guarantee terms?

100% money back. If they don't work for your herd, you don't pay. No fine print, no restocking fee, no forms to chase. Email us and we take care of it.
