From the maker's own dry-cow study: a single calcium-chloride source raised serum calcium faster and held it higher over 24 hours than the market-leading bolus. Blood calcium is already low at calving (left).
From a customer
Straight from the dairy.
“We used many different brands of calcium boluses, none seemed to work consistently or effectively until switching to NoBS. Now we have a product that we can expect results from.”

Straight answers.
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.
