1 billion Correct Dose: Align Digestive Support contains 1 x 109 (1 billion) (4 mg) live bacteria/CFU when manufactured, and provides an effective level of bacteria (1 x 107 CFU) until the “best by” date.

one billion live This product has been tested for accuracy and contains one billion live bacteria/colony-forming units when manufactured and provides an effective level of bacteria (ten million colony-forming units) until at least the best by date.

Probiotics are measured in colony forming units (CFU), which indicate the number of viable cells. Amounts may be written on product labels as, for example, 1 x 109 for 1 billion CFU or 1 x 1010 for 10 billion CFU.

There is no "right dose" of probiotics The average dose of probiotic supplements is 1 to 10 billion colony forming units (CFU) according to the National Institutes of Health. Most probiotics on the market have this amount, though you may see products that claim to have up to 50 billion CFU.

Probiotic doses are measured by colony-forming units (CFUs), and they range from 1 billion to 100 billion CFUs. Perlmutter considers 100 billion to be the highest daily dosage anybody needs to take - and most people need much less than that.

The International Scientific Association of Probiotics and Prebiotics (ISAPP) does not assign a specific amount to their definition of “probiotic”; however, other national health agencies require a minimum of one billion CFU to be labeled as probiotic.

Although the vast majority of existing clinical trials indicate that probiotic doses of 10-20 billion CFU per day are sufficient for maintaining immune and digestive health, research studies examining the dose-response of larger CFUs and products featuring CFUs of 50 to 100 billion are becoming increasingly common.

How much you need varies with different types and what you want to treat. There's no general rule to follow. Most doses range from 1 to 10 billion CFUs that you take once or twice a day. If you don't get enough CFUs, you might not get the results you want.

As a general rule, a probiotic should provide at least 1 billion CFUs (colony forming units, i.e., viable cells), with doses typically ranging between 1 billion and 10 billion CFUs daily for adults.

Probiotics have been found to be safe at very high doses and as of yet, no upper limit to how many probiotics you can take has been found [1, 2]. Side effects are more common with probiotic foods than with probiotic supplements because probiotic foods tend to be high in histamine [3, 4, 5].
