Soylent and Orgain sit at opposite ends of the philosophy spectrum. Soylent is engineered nutrition built for efficiency, using industrial ingredients without apology. Orgain is a certified organic product built by a physician around whole-food sourcing. The labels reflect that split clearly, and one of them has a 9g added sugar problem.

The Sugar and Carbohydrate Problem
Soylent carries 9g of added sugar, the most of anything we have audited, and its carbohydrate base is maltodextrin and isomaltulose. Maltodextrin has a glycemic index that can exceed table sugar, which means the glucose response is fast.
For a product marketed on steady, efficient energy, that combination works against the stated purpose. A rapid glucose rise is typically followed by a corresponding fall, which is the opposite of sustained energy.
Orgain has zero added sugar, sweetened with stevia and monk fruit. On this dimension the gap is as wide as it gets in this category.
Protein: Similar Grams, Different Sources
The numbers are nearly identical at 20g and 21g. The sourcing is not.
Soylent uses soy protein isolate. Soy is a complete protein with a solid DIAAS score around 0.90, so the amino acid profile is genuinely good. The concern is processing: soy protein isolate is typically extracted using hexane, a petroleum-derived solvent, and the FDA does not require hexane residue testing on finished products. There is no disclosure to check either way.
Orgain uses an organic plant protein blend. Lower DIAAS than soy isolate, but organic-certified and free of hexane extraction. Which you prefer depends on whether you weight amino acid scoring or processing method more heavily. We weight processing, which is why Orgain scores better on this dimension despite soy's technical protein advantage.
Vitamin Quality: Orgain's Strongest Dimension
Orgain has the best B vitamin sourcing in the entire category. Its B vitamins are genuinely food-derived, from guava, holy basil and lemon, rather than synthetic isolates added to a blend. That is rare, and it is the main reason Orgain scores 6.8 despite real weaknesses elsewhere.
Soylent uses entirely synthetic vitamin forms throughout.
But Orgain has a serious gap. Vitamin D sits at 0% DV and calcium at 4% DV. For a product sold as a complete meal, no Vitamin D at all is a genuine shortcoming, and it is the single biggest mark against it. Soylent does include Vitamin D. If you choose Orgain, budget for a separate D3 supplement, which is inexpensive and closes the gap properly.
Ingredient Purity
Neither product is clean here, and it is worth being even-handed about that.
Soylent contains both canola and sunflower oil, plus maltodextrin as a carbohydrate base. Orgain contains sunflower oil and rice dextrin, a cheap fiber and filler ingredient.
Soylent is worse on this dimension, carrying two seed oils and the maltodextrin, but Orgain is not seed-oil-free and we are not going to imply otherwise. If avoiding seed oils entirely is your priority, both fail, and Huel, Garden of Life, Ka'Chava and Vega One are the products that pass.
Calories and Purpose
These are built for different jobs. Soylent at 400 calories is a genuine full meal replacement. Orgain at 150 calories is a light meal or a substantial snack that works best with food around it.
Compare them on the right basis. If you need something to actually replace lunch, Soylent's 400 calories does that and Orgain's 150 does not. If you want a lighter addition to a diet that already includes real meals, Orgain fits and Soylent is too much.
Fiber
Soylent has 3g, Orgain has 1g. Both are poor. The category benchmark worth aiming for is 5g or more, and Huel and Garden of Life both hit 7g. Whichever of these two you pick, adding chia, ground flax or a piece of fruit is worthwhile.
Value
Orgain is $2.00 per serving against Soylent's $3.25, so Orgain is cheaper in absolute terms. But Soylent delivers 400 calories to Orgain's 150, so per calorie Soylent is actually the cheaper product.
The honest way to read this: Orgain is better value for what it is, a light organic shake with excellent B vitamin sourcing at a reasonable price. Soylent is reasonably priced for a full 400-calorie meal, and its problem is not cost but composition.
Ownership
Soylent was founded by Rob Rhinehart in 2013 and was acquired by Starco Brands in 2024. Orgain was founded by Dr. Andrew Abraham, a physician and cancer survivor, in 2009, and remains independent, based in Irvine, California. The founder story is genuine and is reflected in the certification-led approach to sourcing.
Who Should Buy Which
Choose Orgain if you want USDA Organic certification, zero added sugar, the best food-derived B vitamins in the category, and a low price. Pair it with a Vitamin D3 supplement and add a fiber source. Accept that 150 calories is a light serving.
Choose Soylent if you need a genuine 400-calorie meal in a bottle and convenience outweighs ingredient quality. Understand that you are accepting 9g of added sugar, a maltodextrin base, two seed oils and hexane-processed soy protein.
Consider neither if you want a full meal without those compromises. Huel delivers 400 calories with 40g protein, 1g added sugar, no seed oils and premium vitamin forms at $2.12.
Frequently Asked Questions
Is maltodextrin actually harmful?
It is not a toxin, but it is a high-glycemic carbohydrate that can raise blood glucose faster than table sugar. As a primary carbohydrate base in a product sold on sustained energy, it is a poor fit, and it is unsuitable for anyone managing blood sugar.
Should I worry about hexane in soy protein isolate?
Hexane is used as an extraction solvent and trace residues are not tested for or disclosed on finished products. The evidence on residual amounts is limited, which is precisely the problem: you cannot verify what you are consuming. We treat undisclosed processing as a mark against a product.
Why does Orgain score higher despite having less fiber and no Vitamin D?
Because vitamin quality carries 20% of the score and Orgain's food-derived B vitamins are the best in the category, while Soylent's are entirely synthetic. Orgain also takes zero added sugar against Soylent's 9g, and carries organic certification. The Vitamin D gap costs it real points, but not enough to close a 1.3-point spread.
Is Soylent good for diabetics?
It is a poor choice. 9g of added sugar on a maltodextrin and isomaltulose base produces one of the fastest glucose responses in the category. Anyone managing blood sugar should review options with their doctor or dietitian, and Orgain at 0g added sugar is a far more sensible starting point.
Do I need to take Vitamin D with Orgain?
If Orgain is a daily habit and you are not getting Vitamin D elsewhere, yes, it is worth covering. At 0% DV, the product contributes nothing on that front. A standalone D3 supplement is cheap and solves it.
Bottom Line
Orgain Organic Nutrition is the better-built product at 6.8 against 5.5, and it costs less per serving. Zero added sugar, USDA Organic, and genuinely food-derived B vitamins are real advantages, and its 0% Vitamin D is a fixable gap.
Soylent's 9g of added sugar, maltodextrin base and two seed oils are not fixable, they are the formulation. Its case is convenience and a genuine 400-calorie meal, and if that is what you need, Huel Black Edition does the same job better at a lower price.
