Is Soylent 2.0 a nutritionally complete shake?
A similar question was asked here, about a previous iteration of it, and the answer was "probably not".
It has been 3 years now and Soylent 2.0 has been out for a while. A lot of people have been trying it out and we might have more data.
I would like to ask a similar question for the new Soylent. Is Soylent 2.0 a nutritionally complete shake?
EDIT: I will define nutritionally complete with Falco's definition below in the comments:
a human can live consuming only this substance for a prolonged amount of time (10 years) without any increased chance of getting nutritional withdrawal symptoms / related diseases compared to an average human with a normal diet

Soy may be a fairly complete protein, but it has alot of estrogen.
And worst soylent is made "proudly with gmo"(as is most of soy) and they use herbicide(namely they seem to imply they are using glyphosate) , and they dare say the health hazards are not proven,that's just a blatent lie.
That alone should make you run away very fast from that product,and just soy in general(unless it's organic,but then again the estrogen content makes it not favorable for daily use)
Theres plenty of alternatives,alot more nutritive also, like sunflower seed kernels nutritiondata.self.com/facts/nut-and-seed-products/3076/2 , pumpkin seeds, peanuts, sesame seeds, theres also plenty of nutritional herbs www.nutrition-and-you.com/parsley.html .
Those data are from Usda official website(relayed by other websites that add the % value)
Soylent 2.0 is made of algae and soy.
Soy may be a fairly complete protein, but it has alot of estrogen.
Only animals have animal hormones, plants don't and even if it did it makes no difference, If males don't become female because they eat cow milk which does actually contain estrogen, and quite a lot due to cow's pregnancy, then ''presumed'' hormones in soy won't have any effect.
Soy it's not ''fairly complete protein'', but has more protein than any meat or any other animal tissue. 36.5% of it's weight is pure protein(1), while most have an hard time going over 20% and pork being the meat with highest protein content at 22%-27% depending on the breed, and soy protein is quite evenly spread across all 9 types of essential proteins, but has also some non-essential proteins like Serine, Glutamic-Acid and many others.
Soy also has almost every micro nutrient a human needs, it even has omega 3 and 6. Out of 11 vitamins it only lacks 2, and out of 9 minerals it only lacks salt.
And for what soy lacks, algae makes up for, It doesn't say what type of algae they use but they mention non-farmed algae,therefore it's wild. Which means it has a high content of B12, B12 is made from bacterial present in non potable water and Vitamin A is found in all algae. About salt, they probably just added the needed salt as it states on their website that 1 bottle of soylent contains 20% of all the nutritional daily needs.
Soylent is true to it's name, it contains all you need and nothing you don't need such as cholesterol.
According to the Nutrition Facts (also here and here) provided by the producer, Soylent contains all the essential nutrients:
Vitamins A, B1, B2, B3, B5, B6, B7 (biotin), B9 (folic acid), B12, choline, C, D, E and K.
Minerals calcium, chloride, chromium, copper, iodine, iron, magnesium, manganese, molybdenum, phosphorus, potassium, selenium, sodium and zinc
Proteins with all 9 essential amino acids and fats with both essential fatty acids
Water
...and various non-essential carbohydrates.
One 414 mL bottle contains 400 Calories, so, to get 2,000 Calories, one would need to drink 5 bottles, which together provides 100% of all essential nutrients, 20 g of fiber, 1.5 g sodium and 45 g of sugars.
Soylent seems to contain all essential nutrients in appropriate amounts, so it is "complete" in this regard. But it is not known if it is complete in the sense that no nutrient deficiencies or nutrient-related diseases would develop after 10 years of its exclusive use, since no relevant studies have been done, so far.
Potential problems with long-term use of this food:
Lack of diversity, so how long could one continue to drink the same thing
Unknown effect on intestinal flora (a study by ClinicalTrials waiting)
Possible absence of certain nutrients, which may be essential, but we don't know yet, if they are
Unknown risk of developing of chronic diseases
