Possible Side Effects

After extensive research on the Number One Nutrition website and the Amazon product page, we could not locate any listed side effects.

Manufacturer’s Commitment

The manufacturer’s commitment is located on Number One Nutrition’s refund policy page. Both in a short video and stated in a banner across the middle of the web page, there is a 100% money-back guarantee for all of Number One Nutrition’s products. There is no further explanation of how the refund and return policy works. The short video states that the customer service team is on hand to help customers through the process.

There are a few testimonials on the Number One Nutrition’s website. But they are general comments about Number One Nutrition and not specifically about the Advanced Probiotic capsules. On Amazon, this product is reviewed 1, 495 times. Overall, Number One Nutrition’s Advance Probiotic capsules received 4.5 starts out of 5. The majority of reviews are very positive. A few found products that work better. Others complained of the pills being too big, and it having a negative effect on their digestive issues.

The Bottom Line

For the vast majority of the customers who reviewed Number One Nutrition’s Advanced Probiotic, they seemed happy with the results. It helped with digestive issues as it claimed it would. Other customers found products that work better. The Number One Nutrition website wasn’t very helpful. We discovered most of the information about Advanced Probiotics from the Amazon product page. Customers should be cautioned that there are no side effects or warnings listed on the manufacturer’s website nor were they listed on the Amazon product page. This could be very dangerous for the customer. Things like potential allergic reactions should be accounted for by the manufacturer. Also, the lack of a written process for their refund and return policy is a challenge for customers. It is important that such information is spelled out for the customer and not just left up to an explanation from the customer support team after the customer has to make time to call.
