Sportgetränk durch Zucker ersetzen?

A 90g bottle of carbohydrates can really add up in sports stores. But do these professional mixes ultimately just contain ordinary table sugar? In this video, we compare expensive brand-name products with an extremely affordable DIY solution from the supermarket. We explain the biological limits of our gut, how the SGLT-1 and GLUT-5 transporters work, and why osmolarity can mean the difference between victory and stomach problems. Is the extra cost for professional nutrition really worth it? 🚲 Send us pictures or videos of your bike and with a little luck, you could be featured in our weekly show 👉 https://gcn.eu/UploaderDE Become a channel member and get lots of benefits and bonus content: https://gcn.eu/JoinGCNaufDeutsch Do you have a question?
