The HVMN stuff is by far the worst tasting thing I’ve ever had the pleasure of trying. But I actually kind of like the Delta G taste. It’s bitter but for some reason it’s like a good bitter. I don’t mind it at all. The Ketoneaid was definitely worse, but not too bad.
I also tried the Delta G coffee shots which were not good but you could take it like a shot.
For results, I feel like I have a little more energy at the end of rides. I don’t feel as beat. Couldn’t say if that’s a placebo or not. I also only take 5-10g per ride, which worked out to around $.83 per g, so around $4-8 per ride. Still too expensive for everyday rides but I’ll take it for my long weekends rides. I mean, Science in Sport is $1.50 per gel and I see people taking 4 or 5 of those on a ride. $10 for a long weekend ride is $40/month. Not terrible.
I think it’s not so much a utilization problem. Ketones don’t require active transport to mitochondria to be metabolized. Rather the kidneys are good at clearing them when insulin is elevated. So in keto, the ketones hang around. In carb diets, they are excreted more quickly. Unfortunately I don’t have any data on percentages, so I wouldn’t say it’s no good – and there is research on ketone supplements in high-carb athletes improving recovery – but it sure hurts to pay so much for something only to pee out a non-trivial percentage of it.
This is where I am too. Lots of people will say things like “I feel like it does x”, but imho, that sounds like confirmation bias. I feel the same way about things like Amp Human. Basically, if Lance advertises it, I assume it’s snake oil.
