It's official: all-in-one meal supplement (or replacement) Soylent has a nutrition label.

In a blog post two weeks ago, Soylent founder Rob Rhinehart noted that the company had decided to produce a single 2,000-kilocalorie version for its initial production run; beta versions (including the 0.89 Beta formula we tried) came in male and female variants. The single launch formula means that a single nutritional label can be applied to all the packages of Soylent going out the door.

In its shipping form, a three-serving bag of Soylent clocks in at 2,010 kcal, with 630 kcal from fat—that's with the combined package of canola and fish oil added into the mix. Altogether, a full day's worth of Soylent 1.0 will give you 1,050 mg of sodium, 3,465 mg of potassium, 252 total grams of carbs (including 24 g dietary fiber and 6 g of sugars), and 114 g of protein. There's no cholesterol in the dry ingredients; the oil mix adds about 15 percent of your daily recommended cholesterol intake (specific numbers on the oil aren't included as part of the label).

Running down the percentages, it appears that at least as far as the label lab testing can show, Soylent delivers on its promises. Every listed micronutrient comes in at least 33 percent per serving.

"The label marks an important milestone, but it is also revealing," Rhinehart said to Ars in an e-mail exchange this afternoon. "Many assumptions go in to nutrition facts. Some nutrients break down quickly, many are lost in cooking or poorly absorbed, or may be absorbed too quickly. Fortunately, these are not issues for Soylent."

The labeling also removes a lot of roadblocks from what Rhinehart is allowed to say about Soylent. When we checked in with Rhinehart at the end of our Soylent adventure in September, he made it very clear that the company wasn't attributing any medical or health benefits to Soylent. "We're not making any medical claims here," he explained at the time. "Soylent is not a drug, basically, and we're not testing on that level. We are designing a number of studies to catalog the health benefits, though—a lot of people are seeing reduction in triglycerides or cholesterol; others are seeing improved performance or sleep."

However, the results of the nutrition testing done to gain the label have established that Soylent meets the Food and Drug Administration's standards for a whole raft of healthy claims: "Everything from reduced risk of heart disease and some cancers to absence of tooth decay," said Rhinehart. Based on the testing, he explained, Soylent can make many of the health and nutrient claims that the FDA tracks.

"What we cannot legally say," he quipped, "is that one can live exclusively on Soylent forever, as that would imply it will make you live forever."

Which brings us back to the question of when. Soylent started as a crowdfunded campaign on Crowdtilt, and as it continued to gain in popularity and funding, the targeted shipping date slipped further and further to the right. With the latest update, backers should see their first shipments arrive near the end of February or the beginning of March; non-backers should be able to buy Soylent at around the same time.

I'm a backer myself, having put some of my own hard-earned Ars salary dollars down for a month's supply of the stuff last August, and I asked Rhinehart when my shipment was going to land on my doorstep. "After dozens of revisions we have settled on a v1.0 I am very confident in and will begin shipments on a rolling basis at the beginning of March. You're going to love it," he replied.

Love it? Could be—you can definitely expect that we'll be taste-testing our production Soylent for Ars when it arrives.
