I don’t taste them, I swallow them - and I never notice the taste. If you split them up over three meals, it’s just 3 tablets per. I tend to do breakfast/dinner, and actually take five each, for ten daily - but I’m a very large active man. The tablets aren’t large, they’re typical, to me.
I did try using the powder version, and putting it in the mix. Bad idea. Terrible flavor effect; adds sourness and bitterness, which I attributed mostly to the vitamin C.
I’ve been using up the powder, dissolved in a little water, as a daily vitamin outside the soylent: it has an intense sour/blueberry/tart grass taste. It’s more than just the sourness of the vitamin C, and it’s not a flavor that goes well into a mix, unless you’re making something tart to cover it, like lemonade flavor drink or something. Not recommended for blending.
I’m going back to the tablets, which I’ve used for a long time. They have no flavor, to me, but I don’t chew or suck on them. Just wet and swallow.
In the end, I’d much rather do my supplements as tablets, rather that putting them in the soylent - less ingredients to measure mix when making batches, and fewer things to mess with the flavor profile. Also, I’m noticing that I don’t need to pre-soak my powder before the oil, or to chill it, to avoid unpleasant flavors… in fact, I’m toying with how much I can heat it in the microwave when I want a warm drink for a meal, and it still tastes fine.
