Considering many people who want to use Soylent want maximum control over their diet, I’m hoping the “Extras not considered essential” listed on @rob’s blog will be removed, for a number of reasons.
For starters, some of these can interact with various prescription medications. Both ginseng and gingko biloba can adversely affect blood thinners, for example.
Also some people are sensitive or even allergic to gingko and lycopene.
For those of us taking supplements (for example, nootropic stacks) it’ll be more difficult to figure out the dosage of what we’re consuming if some of this is included in the drink. Ginseng for example.
Also, really hoping gingko biloba gets removed based on a serious potential cancer risk to the liver: http://www.consumeraffairs.com/news/ginkgo-biloba-linked-to-cancer-in-mice-and-rats-042613.html
