What is First Saturday Lime?


First Saturday Lime is a natural refined mineral. Specifically, it’s PCC (Precipitated Calcium Carbonate) — also known as purified, refined calcium carbonate. It has the same composition as other types of calcium carbonate, such as limestone, marble and chalk.

Calcium carbonates, including PCC, are considered to be non-toxic. In the U.S., the Food and Drug Administration has Affirmed calcium carbonate to be GRAS (Generally Recognized As Safe). We’ve taken the extra step to get our lime tested to ensure we exceed purity requirements to deliver the most effective lime that’s safe for your family, gardens, ponds, pets and animals.

Why Should I Use First Saturday Lime?

While other limes are caustic, or poisonous to humans and animals, First Saturday Lime is safe because it’s derived from the earth without any additives. We’ve taken extra, lengthy steps to make our formula fine (with a cake flour like consistency) so it’s easier to use, and tested it so you feel safe using it. With over 50 years in the agriculture business, our family is confident and competent in the best practices necessary to offer an age old natural pest repellent like this one.

We welcome any suggestions or questions that might improve your experience so please do not hesitate to reach out to us by giving us a call or sending us a message here.

If this stuff is so great, why have I not heard of it before?

Unfortunately, too many corporations are “all about the money.”  With money as their primary goal, they’re not too motivated to spend millions of dollars and years of research on a natural product with minimal financial returns.  As a result, First Saturday Lime (or PCC) is one of hundreds of natural products that are unrecognized and often forgotten – even though they are natural, safe, non-chemical products.

Most First Saturday Lime (or PCC) is used by someone who has a friend or relative that has used it and gotten results.  You would think that is would be just the opposite—that a natural, safe, non-chemical product that is inexpensive and has so many uses would be in every home in the country, but chemicals and drugs are where the big money is, so that is what gets promoted and used.

We put loved ones first and extend this to the way we do business. We love our customers and are passionate about using PCC lime to protect and improve lives, gardens, farms, pets and animals now and for generations to come.
