I learned about this probiotic from an article about deworming. I take it on an empty stomach every night before bed. I'll continue taking it for three months to see how it goes.

Reliable benefits especially when taken, paused and resumed.

Verified Purchase

Iherb has the best price on Theralac Probiotics found online. when automatically scheduled shipment. It's very convenient that Iherb also allows the subscription to be canceled if desired. It arrived in packaging that was minimal as possible yet kept the product safe and dry. The expiration date is far enough that there's plenty of time to use product.

Love this probiotic

Verified Purchase

Been taking for years - it is a great effective probiotic that you can notice the results. Changed probiotic and noticed the difference so I am once again back on Theralac and this is when I found IHerb - The price at IHerb has one of the best prices for the product.

This is a wonderful product. I chose it based on several factors: price, excellent taste, product quality, excellent results, rich nutritional content, convenient packaging and beneficial ingredients, the ability to choose the size and dosage, great health and sleep benefits, natural ingredients (serotonin and amino acids), and a mood booster. I recommend this wonderful product to everyone; it fully meets the description and expectations. No issues were encountered.
