What Is Silk Protein Nutmilk?
Silk Protein Nutmilk is the soy-free entry in Silk's protein-fortified milk lineup. Where the original Silk Protein line is built on soymilk and soy protein isolate to hit 13 grams of protein per cup, Silk Protein Nutmilk swaps that base for almondmilk, cashewmilk, and pea protein, landing at 10 grams of protein per cup instead. It's marketed at the growing crowd of shoppers who want a plant milk that does more than splash into coffee — something that can stand in for a protein shake, a smoothie base, or a genuine breakfast that keeps you full.
It comes in a 64 fl oz (half-gallon) carton and is sold in Original, Vanilla, Unsweetened, Unsweetened Vanilla, and Chocolate varieties, with the unsweetened versions dropping to 110 calories and 0g added sugar. It's shelf-stable until opened, then refrigerated, and it's positioned on shelves right next to Silk's regular almondmilk and the soy-based Silk Protein — which makes the two lines genuinely easy to grab by mistake if you're avoiding soy or trying to maximize protein.
Ingredients
The full ingredient list for Silk Protein Nutmilk Original reads: Almondmilk (Filtered Water, Almonds), Cashewmilk (Filtered Water, Cashews), Pea Protein, High Oleic Sunflower Oil, Contains 2% or less of: Cane Sugar, Sea Salt, Natural Flavor, Calcium Carbonate, Sunflower Lecithin, Gellan Gum, Vitamin D2, Ascorbic Acid, and Vitamin E Acetate.
A few things stand out. There's no soy protein isolate or soybean derivative anywhere on the label — the protein comes entirely from pea protein plus whatever incidental protein the almonds and cashews contribute. The fat comes from the nuts themselves plus added high oleic sunflower oil, which is what gives the product its noticeably thicker, creamier mouthfeel compared to standard almondmilk. Gellan gum and sunflower lecithin are there purely as stabilizers to keep the pea protein and nut solids from separating in the carton — a common, food-safe additive in plant milks and not a vegan red flag.

Is Silk Protein Nutmilk Vegan?
Yes — Silk Protein Nutmilk is vegan. Every ingredient on the label is plant-derived: almonds, cashews, pea protein, sunflower oil, cane sugar, and a vitamin/mineral blend that uses D2 (the plant-based form of vitamin D, as opposed to D3, which is frequently sourced from sheep's wool lanolin). There's no dairy, honey, gelatin, casein, whey, or any other animal-derived stabilizer in the formula. Silk's parent company, Danone, also lists the product as vegan and dairy-free on its own site, and it carries Non-GMO Project Verification and Kosher certification, neither of which conflicts with a vegan ingredient list.
The one caveat worth flagging isn't about the ingredients — it's about shelf placement and labeling. Silk sells a nearly identically packaged soy-based Silk Protein line right alongside this one, and while that version is also vegan, it's a completely different formula (soy protein isolate instead of nuts and pea protein) with a different allergen profile. If you're avoiding soy specifically, read the front of the carton carefully — "Silk Protein" and "Silk Protein Nutmilk" are two different products with overlapping branding.
Nutrition Facts Comparison
Here's how Silk Protein Nutmilk Original stacks up against its closest competitors in the "high-protein plant milk" category, all normalized to a 1 cup (240ml) serving.
| Product | Calories | Protein | Total Fat | Sugars | Calcium |
|---|---|---|---|---|---|
| Silk Protein Nutmilk Original (almond/cashew/pea) | 130 | 10g | 8g | 2g | ~450mg |
| Silk Protein Original (soy) | 130 | 13g | 4.5g | 4g (3g added) | 470mg |
| Ripple Unsweetened Original (pea) | 70 | 8g | 4.5g | 0g | 450mg |
| Silk Unsweetened Almondmilk (regular, for reference) | ~35 | 1g | 2.5g | 0g | 450mg |
The numbers tell a clear story: Silk's soy-based Protein line still wins on raw protein grams and is lower in fat, since soy protein isolate is more protein-dense than a nut-and-pea blend cut with added oil. Ripple comes in leaner on calories and fat while still delivering a respectable 8g of protein with zero sugar in its unsweetened version. Silk Protein Nutmilk Original sits in the middle — more calories and fat than Ripple, less protein than soy-based Silk Protein, but the only one of the three that's both soy-free and nut-inclusive, which matters if soy is the allergen you're actually avoiding.
Taste and Texture
This is where Silk Protein Nutmilk splits opinion. The added sunflower oil and pea protein give it a noticeably thicker, richer mouthfeel than a standard almondmilk or oat milk — it pours slower and coats a spoon the way a light cream would, rather than behaving like a typical thin nut milk. Poured straight into a glass, that thickness reads as slightly heavy, even a little chalky at the back end, which is a known trait of pea-protein-based beverages generally (Ripple has the same reputation). It's not unpleasant, but it's not the light, clean sip you'd get from Silk's regular unsweetened almondmilk either.
Where it performs better is in applications that mask that texture: blended into a smoothie, poured over hot oatmeal, used as a coffee creamer substitute, or worked into a protein-boosted pancake or baking recipe. The natural flavor and light cane sugar in the Original version round out the slightly beany edge that unflavored pea protein can carry, and the Vanilla version does an even better job of covering it. If you're sensitive to pea protein's flavor signature, the Unsweetened Vanilla variant is the safer starting point over Original.
For reference, dairy milk itself carries about 8 grams of protein per cup with almost none of the thickness complaints, which is exactly why pea-protein-fortified plant milks still get compared unfavorably on mouthfeel even when they match or beat dairy on the protein numbers. Silk Protein Nutmilk closes that gap better than most of its plant-based competitors, but it hasn't fully closed it — anyone expecting it to pour and taste exactly like 2% milk is going to notice the difference within the first sip.
How It Compares to Alternatives
| Product | Protein per cup | Soy-free? | Best for |
|---|---|---|---|
| Silk Protein Nutmilk Original | 10g | Yes | Smoothies, oatmeal, baking, soy-free households wanting extra protein |
| Silk Protein Original (soy) | 13g | No | Maximum protein per cup, lower fat |
| Ripple Unsweetened Original | 8g | Yes | Lower calorie, zero sugar, drinking straight |
| Orgain / other protein shakes | 16-21g | Varies | Meal replacement rather than a milk swap |
Price and Value
Silk Protein Nutmilk Original ships in a 64 fl oz (half-gallon) carton and is stocked in the refrigerated dairy-alternative case at most major U.S. grocery chains — Kroger, Fred Meyer, Harris Teeter, Food 4 Less, Metro Market, and their affiliated banners all carry it, alongside availability through delivery apps like Instacart. It's priced in line with Silk's other premium, protein-fortified plant milks, which typically run a few dollars more per carton than a standard unsweetened almondmilk — the trade-off for the added pea protein and nut content. Given that a single serving is delivering a meaningful 10 grams of protein rather than the 1 gram you'd get from a regular almondmilk, the per-gram-of-protein cost is reasonable if you're actually using it as a protein source and not just a splash for coffee, where the extra cost buys you nothing.
Compared to buying a separate protein powder and mixing it into a cheaper plant milk yourself, Silk Protein Nutmilk is more convenient but almost certainly more expensive per gram of protein. The value case here isn't "cheapest protein," it's "protein without extra steps" — you're paying for a ready-to-pour product that already tastes reasonable and doesn't require a blender or a scoop.
Who Should Buy This
Silk Protein Nutmilk Original makes the most sense for people who specifically need to avoid both dairy and soy but still want a plant milk that pulls more nutritional weight than the typical almondmilk carton — think soy-allergic households, people managing thyroid medication timing around soy, or anyone who's simply decided soy isn't for them but still wants protein in their cereal bowl. It's also a reasonable pick for anyone trying to boost protein intake without reaching for a powder every time, since it works as a near drop-in replacement anywhere a recipe calls for milk.
It's a less obvious choice if soy isn't a concern for you — in that case, Silk's own soy-based Protein line delivers more protein for the same calories and less fat. And if you're mainly drinking milk straight rather than cooking or blending with it, the thicker, slightly gritty texture here is worth tasting before you commit to a half-gallon.
Final Verdict
Silk Protein Nutmilk Original does what it says on the carton: a genuinely soy-free, dairy-free milk with a real, verifiable 10 grams of protein per serving and a clean, fully vegan ingredient list. It's not going to out-perform Silk's own soy-based Protein line on raw protein-per-calorie efficiency, and the texture is thicker than some drinkers will want for a straight glass of milk. But as a smoothie base, oatmeal topper, or baking substitute for anyone specifically steering clear of soy, it's one of the more solid options currently on shelf.
Rating: 7.6/10 — Reliable, clearly labeled, and genuinely useful for the soy-free-and-high-protein niche it's built for, docked slightly for texture and for costing more per gram of protein than the soy version sitting next to it.
