I use half the recommended dosage (so only 8 sprays twice a day instead of 16) and it lasts me about two months.

Depends of your specific need. My son for instance do better on 4 daily. Most of us only need 1 daily. So, if one is enough for you, than it would last 2 months a bottle.

Excellent question - I wondered this myself. From what I know, the bottles are made to order because of their short shelf life. Once opened, they have a shelf life of 30-60 days. If not opened AND kept in a dark, dry atmosphere, I believe they're potency begins to breakdown after 6 months. Because of this, I do not buy more than one bottle at a time, but you can decide for yourself how fast you'd go through each bottle and buy accordingly. If anyone knows better or has other information, I invite them to reply to your question. You may also contact the manufacturer for their version of what the truth may be. Enjoy the product!

Because of the cool way the bottle works this product can last quite a while. 20 to 30 days, easily.

Hey John, One bottle lasts about 30 days. If you have a multiple cat family it sure helps! I love this stuff! Keeps my cats a lot calmer then without it.

I have bought bottles like that before. If you leave some of them sealed. I think they will last at least a year. Only open one at a time. I hope this helps. Donna

Every bottle has their own expiration date. The bottles I've bought have an expiration date of well over a year. I bought a bottle a few months ago and the expiration is 12-14. This is a product that needs to STAY REFRIGERATED. Make sure the company you buy it from sends it in a refrigerated package or you might lose its effectiveness if it reaches room temperature.

Eash bottle is sealed, so after you open it, you have 30 days to use the solution, if you don't you are to throw it away. One bottle lasts me a little over a week.

Each bottle usually last 2 years if you put it in a dry and cool cabinet shelf (every bottle has labeled "best used by" dates). The power tends to harden if you let it sit too long or stored in high humidity environment. Take it 2-3 times a day on a empty stomach (before meals) and a 10.6 oz (300g) bottle will only last 30 - 45 days. Caution: avoid moisture at all time. Keep it as dry as possible. Hope this helped.

It is good for at least one year, whether kept at room temperature or refrigerated. Each bottle should bear an expiration date.

One bottle lasts about 4-6 months, I called the company and there are no expiration dates on this type of product. Works for me!!

I don't know for sure. 1 bottle lasts my husband and I little over a month. I prefer the liquid only because I know its mixed correctly.

We never counted. For us, opening about 4-6 bottles weekly, it lasts probably 4-6 months. This is just a guess, but we love using it and it doesn't seem to have to be replaced but 1-2 times a year.

Just a guess would be around 30 or so . One container will last me for 3 to 4 months .

I started out using 2 caplets per day so one bottle would have lasted 30 days. Right now I am taking one per day, so a bottle lasts me 60 days. One per day is working very well for me
