I suspect that most people dont actually need the extra sugar in chocolate milk for “recovery” so surely better off having something without it and a lot more protein?
Isn’t the point of protein in recovery drinks that it helps – for reasons that aren’t fully understood – your body to absorb the carbohydrate more efficiently. What you’re actually trying to do is replenish the blood/muscle glycogen reserves which get depleted during intense activity. So actually in recovery terms, the sugar is what need, the protein just helps you absorb it better.
That’s how I’ve generally understood it anyway, though of course I may be wrong. I think there’s some evidence to show that protein helps to suppress food cravings/appetite/stops you feeling ’empty’, but that’s a different thing, though I guess if you’re prone to pigging out maybe a useful one.
Anyway, if it works for you.
