be absorbed so you can start gaining the benefit
it depends on how low your stores are when you take the gel, if you’re bonked, TBH it won’t do much, but if you’re keeping up with your carb intake, you’ll feel fine regardless.
Can’t see the logic in that at all. “bonked” usually refers to a depletion in muscle and liver stored glycogen. When you consume carbohydrate it will be available in the blood stream (dependent on several factors as mentioned) for the use by cells. If you are bonked, and will therefore have low blood glucose you WILL see the benefit once its available.
I did see some availability data recently of when consumed carbohydrate was available for cells but can’t find the reference I’m afraid. If I remember correctly gels where a surprising 30 mins. Still quicker than something like a banana though.
