Spirulina is far from a good health choice. It got popular because it contains a molecule that's similar to B12, but it turns out that it's not B12. But it does bind to B12 intrinsic factor, which is a problem because intrinsic factor production, not B12 consumption, is frequently the limiting factor in how much of the nutrient you can get into your system.

Or, to put it more succinctly - spirulina : B12 :: CO : O2.

And while I'm laying it on, probiotics isn't really all that impressive, either. Right now the food industry's approach to probiotics is, at best, comparable to the kind of thinking that caused to large swaths of the USA to have problems with kudzu and asian carp.

I recently tried Ample Original and AmpleX, and I like Ample Original quite a bit. The only other product I've tried is from Super Body Fuel, though that one had a pretty different macronutrient profile and required some preparation.

I agree that the focus on nutrition is a huge benefit. In addition, I appreciate the transparency of the company and what seems to be a desire to iterate and improve on their product. Today, they announced a few small tweaks to their formula and released a "change log" (their choice of word) detailing the reasons behind their choices.

Do you personally feel any physically different or have noticed any health improvements upon switching to Ample from Soylent?

Looks great. I've been using Huel, the British Soylent knockoff, for 1-2 meals per day (much healthier than the 4oz bag of chips it replaced), and now that I'm moving back to America I'm looking for local alternatives.

Looks good but doesn't list many vitamins or minerals on the label.

It contains an unnecessary amount of protein if you're only consuming Ample.
