The Complete Handbook of Nutrition Gels & Chews

As a coach, I've read a lot of pseudoscience in the endurance world, so this was a breath of fresh air. The explanation of osmolality and the dual-transport carbohydrate system in the first chapter alone was worth the price. It’s structured like a textbook but readable like a guide. I've already recommended it to my entire team, and I'm using the selection framework from Chapter 3 to rebuild our fueling plans.

I picked this up to understand the business side of selling gels at my bike shop, and it delivered more than expected. The technical specs in Chapter 2 are a bit dense for someone without a science background, but they're thorough. I appreciated the neutral tone; it didn't try to push one brand over another. The data on shelf-life and temperature sensitivity has already changed how we store our inventory.

There's a lot of good, solid information here, but I found the tone a little like reading a lab manual in parts of Chapter 1. That said, the chapter on choosing the right product was incredibly practical, and I've used it to figure out why certain gels give me a stomach ache. It's a reference book, not a light read, but for a serious hobbyist like me, it’s a valuable addition.

Finally, a book that treats the topic with the seriousness it deserves. The breakdown of maltodextrin vs. fructose ratios and how that impacts gut comfort during a 100-miler was spot on. The business chapter is also a goldmine for someone thinking about private labeling. It’s not fluffy; every paragraph has substance. I've got dog-eared pages all over my copy.

Overall, it's a useful resource and covers a lot of ground, but I wish it had more specific product comparisons as actual case studies rather than just the specifications framework. The chapter on troubleshooting was helpful when I had a batch of chews melt, but I felt the explanation of how to prevent it was brief. It’s a good book for learning the fundamentals, but not the last word on every practical detail.

It's a fair, well-researched overview of the industry. The first half of the book is very heavy on theory and physiology, which I found slow going. But if you get through that, the second half about the market, brands, and business opportunities is genuinely valuable and insightful. I bought it for the business side, and I’m glad I stuck with it, but it's not a quick read.

I bought this as a buyer for our family's grocery store chain to understand this product line better. It did a great job of outlining the key differences in texture, packaging, and ingredients across various price points. The chapter on installation and usage was a bit odd for a book on this topic—I just assumed you tear and eat the gel—but it clarified proper hydration alongside it. Good, practical addition to our business library.
