“Since starting Sugar Shift probiotics, I’ve noticed a remarkable improvement in my daily life. My blood sugar levels are more stable, and my overall well-being has definitely improved. My naturopathic doctor is fully on board and recommends I continue using these probiotics. I appreciate the extensive research behind the product, making it a reliable addition to my routine. Highly recommend!”

Julie B, Sugar Shift® Customer

“I have been using sugar shift for 4 months and I love the product. What i have noticed the most is how it decreases cravings for sugar and carbohydrates which is precisely what i needed. As wonderful as the product is, the company itself is as wonderful. I have emailed them multiple times with various questions and have always received prompt and detailed answers.”

Carolyn S, Sugar Shift® Customer

“Remarkable help with bowel movement. Regularly. I have suffered for ~20yrs and now am getting relief.”

Carole C, Sugar Shift® Customer

“Love it… sleeping like a baby again 😊”

Claudia, Simple Slumber™ Customer

“I definitely noticed a difference in my processing of sugars because even on my clean eating I was still losing the pounds I wanted to lose.”

Sharon W, Sugar Shift® Customer

“These products have been wonderful for a reset for my body and have incredible results worthy to be noted! Martha and all those she works with have gotten to the root(s) of what our bodies need to function well. My family and I are deeply grateful for their diligent work creating these products.”

Kristin P, Sugar Shift® Customer

“I am absolutely amazed by this product! Within the first couple of days I could already feel a gentle decrease in hunger. Then came what seemed to be a sensation of fullness earlier while eating than before I started taking it. Now, I can actually fast without feeling like I'm losing my mind! Amazing!”

Christine L, Sugar Shift® Customer

“Whenever we have someone in our family that needs antibiotics we give them a few of these and it works every time to get them back to normal.”

Gina A, Antibiotic Antidote® Customer

“I live the Keto lifestyle, but I found after taking BiotiQuest for a month, things started to change. I found it easier to maintain my weight and I was so much more regular. I have reordered and will continue to do so. I can't wait to go to my hormone doctor to see what my sugar levels are now!”

Catherine R, Sugar Shift® Customer

“This probiotic at bedtime is amazing. It helps me settle down and get drowsy. THANK YOU.”
