Reviewers most often praise ProLon's product quality and the ease of following the 5-day kits, frequently noting clear day-labeled packaging and positive results. Customer service and delivery operations receive many positive mentions, but a subset of reviewers report significant billing, checkout or subscription problems. Price sensitivity appears regularly: reviewers recommend watching for discounts or promotions because several experienced unexpected charges or price increases.

I recently tried ProLon's Fasting Nutrition Program and I must say, it was a great experience! The 5-day meal kit was perfectly planned to provide my body with nourishment while keeping it in a fasting state. What impressed me the most is how easy and convenient it was to follow this program.
During the five days of fasting, I felt more energetic and focused than ever before. My digestive system felt much lighter, and I could already see some positive changes like weight loss, better metabolism function, cellular renewal, etc.
