9 Best All Natural Protein Powder | Nature’s Best Protein

simply tera’s proves that clean protein does not need a twenty-ingredient label. With just four ingredients — grass-fed whey, organic stevia, vanilla from the Bourbon Islands, and a touch of organic sunflower lecithin for mixability — this is about as close to making protein powder in your own kitchen as you can get. The 21 grams of complete protein come from happy, grass-fed cows raised without rBGH, and the amino acid profile includes all 18 amino acids, including the nine essential ones your body cannot produce on its own.

What surprised me most is how well it performs in hot coffee. Most whey proteins curdle the moment they hit a hot beverage, but simply tera’s Bourbon Vanilla blends smoothly without clumping or separating. The vanilla note is distinct but not artificial, and the organic stevia provides a gentle sweetness that works in smoothies, oatmeal, or pancakes without overwhelming the other flavors. A number of long-time buyers mention using it as a daily creamer replacement in mushroom coffee.

The one honest limitation is the serving count — the 12-ounce tub delivers about 12 servings, which means you will be reordering more often than with a bulk container. Still, for a brand that prioritizes ingredient purity over volume discounts, the per-serving quality is hard to beat. If you want a protein powder that tastes like real food and mixes into anything without fuss, this is your daily driver.

AGN Roots is the most heavily certified whey protein I have encountered. It carries the “Entire Life on Pasture” certification from A Greener World — the gold standard for animal welfare — plus Informed Sport and Informed Protein verification, meaning every batch is tested for over 250 banned substances, 400-plus pesticides, heavy metals, gluten, and glyphosate. It is also the only whey isolate recognized by the ASPCA’s Shop with Your Heart program. If certifications matter to you, this is the benchmark.

The protein itself is a cold-processed, undenatured isolate that delivers 25 grams of protein per two-scoop serving with 6.5 grams of naturally occurring BCAAs — roughly 10 percent more than most competitors. The unflavored, unsweetened profile tastes like fresh dairy cream with no bitterness, and it blends effortlessly into coffee, shakes, or even sprinkled dry on waffles and rice cakes. Customers consistently praise the fluffy texture and the absence of any chemical aftertaste.

The practical trade-off is the pouch format and the 1-pound entry size. The thermally protected pouch keeps the protein fresh and reduces plastic waste, but it is less convenient for scooping than a traditional tub. And while the per-serving cost is competitive with premium brands, the 1-pound bag goes fast if you use two scoops daily. Still, for anyone who wants the highest possible standard of purity and ethical sourcing, AGN Roots delivers something most brands cannot — proof.

Ancient Nutrition takes a different approach to “all natural” by focusing on collagen rather than traditional muscle-building protein. This Cold Brew flavor combines 9 grams of hydrolyzed collagen from five sources (grass-fed bovine, chicken, eggshell membrane, and wild-caught fish) with 42 milligrams of natural caffeine — roughly half a cup of coffee. It is designed for people who want skin, nail, joint, and gut support alongside a gentle energy lift, not a post-workout massive protein spike.

The sourcing is genuinely clean: no antibiotics, no growth hormones, no chemicals. The bovine collagen comes from grass-fed and pasture-raised cows in South America, the chicken and egg collagen from Midwest US farms, and the fish collagen from wild, cold-water, sustainably harvested North American sources. The powder dissolves instantly in cold water with a mild coffee-vanilla flavor that is not sweet — a major plus if you are sensitive to stevia or monk fruit aftertastes.

Regular users report noticeably stronger nails, thicker hair, and improved joint comfort after a few months of daily use. The collagen also supports gut health, which several reviewers mentioned as a welcome side benefit. The main consideration is that collagen is not a complete protein for muscle synthesis — it lacks tryptophan — so this works best as a complement to whey or plant protein, not a standalone replacement. If your goal is beauty-from-within and joint resilience, this is your powder.

Orgain’s Vanilla Bean plant protein is the goldilocks option for people who want a clean, allergen-free powder without the earthy funk that plagues many plant blends. The protein comes from organic pea, brown rice, and chia seeds — a combination that delivers a complete amino acid profile with 21 grams of protein per serving and only 5 grams of net carbs. It is certified USDA Organic, vegan, gluten-free, and contains no soy ingredients, artificial colors, flavors, sweeteners, or preservatives.

The texture is noticeably smoother than earlier generations of plant protein. It mixes well with water alone, but shines when blended with unsweetened coconut milk, a handful of spinach, and some frozen fruit. A 67-year-old reviewer who uses it to maintain muscle reported noticeable arm-strength gains after switching from whey, and long-term vegetarians appreciate having a clean option that does not cause inflammation or digestive discomfort. The vanilla flavor is subtle and works equally well in coffee or overnight oats.

Some users find the sweetness level a touch high for their preference — Orgain uses organic stevia and monk fruit, which can linger on the palate. The tub is also on the larger side (2.74 pounds), which is great for value but means you are committing to a specific flavor for a while. If you need a reliable, certified organic plant protein that actually tastes good and fits a low-carb lifestyle, this is a top contender.

Vega’s All in One is exactly what the name promises — a protein powder that doubles as a greens supplement, probiotic, and multivitamin in a single scoop. The 20 grams of protein come from organic pea, sunflower seed, and pumpkin seed, delivering all nine essential amino acids without any soy or dairy. Beyond protein, you get 6 grams of fiber, 500 milligrams of omega-3 ALA, 2 billion CFUs of Bacillus coagulans probiotics, and 50 percent DV of eight vitamins and minerals including antioxidants A and C.

The unsweetened version is a blank canvas that savvy users mix with mocha or chocolate flavors to control sweetness. It has an earthy, whole-food taste that works best when blended with fruit rather than just water. One reviewer who practices intermittent fasting uses it as a midday brain-fuel shake with almond milk, banana, berries, and spinach, reporting steady energy without a sugar crash. The certified B Corp status and USDA Organic certification add another layer of trust for ethically minded buyers.

The trade-off for all those nutrients is that the powder is not as neutral-tasting as a straight pea or whey isolate. The greens and probiotics contribute a distinct flavor profile that some love and others find challenging. It also requires a blender for optimal smoothness — a shaker bottle alone may leave small specks of greens. If you want an all-in-one nutrition solution that replaces multiple supplements, Vega delivers real convenience with clean ingredients.

NutraBio has been a quiet favorite among label readers for years because of its obsessive transparency. Every tub comes with a full disclosure of every ingredient and its source — no proprietary blends, no hidden excitotoxins, no “natural flavors” that could mean anything. This is a straight-up whey protein isolate with 25 grams of protein per serving, a complete amino acid profile, and nothing you do not need. It is also soy-free, gluten-free, keto-friendly, kosher, and halal-certified.

The Creamy Vanilla flavor is genuinely good — not just “good for a protein powder” good. It mixes cleanly in water or milk with a frother and delivers a smooth, clump-free texture that rivals far more expensive brands. Long-term users who have been buying protein since the Joe Weider era consistently call it the best they have ever used. The sunflower lecithin used for emulsification is non-GMO and provides natural antioxidant benefits, unlike the hexane-processed soy lecithin found in many competitors.

The 2-pound tub offers 30 servings, which is a reasonable middle ground between the small premium tubs and the giant bulk containers. A 57-year-old reviewer recovering from surgery specifically praised the isolate form for better absorption and faster recovery compared to standard whey concentrate. The only real critique is that the sugar content is not listed on the nutrition facts panel (though it is negligible in an isolate). If you want a no-excuses, third-party-verified whey isolate with great taste, NutraBio earns its reputation.

Orgain’s Peanut Butter flavor is a rare find in the clean protein world — a plant-based powder that actually tastes like the real thing without relying on artificial flavorings or excessive sweeteners. The 21 grams of organic protein come from peas, brown rice, mung beans, and chia seeds, creating a complete amino acid profile with all nine essentials. Each serving also delivers 7 grams of prebiotic fiber for gut support, making this a dual-function powder that nourishes both muscle and digestion.

The texture is remarkably creamy for a plant protein, blending smoothly in a shaker bottle or blender without the chalkiness that plagues many vegan options. Users who mix it with chocolate powder and banana describe it as tasting like a peanut butter cup milkshake — high praise for a product with no added sugar and no artificial ingredients. The peanut butter flavor is present but not overpowering, which works well for those who want a subtle nutty note rather than an intense punch.

A couple of reviewers noted that the peanut butter flavor could be stronger, and if you are expecting the richness of real peanut butter, you may find it mild. But for a clean, low-carb, vegan protein that keeps you full for hours without digestive upset, this is a standout. The 2.03-pound tub provides 20 servings, which is reasonable for the quality. If you are looking for a flavorful plant protein that does not compromise on ingredient purity, Orgain’s Peanut Butter delivers.

Nutricost’s Organic Pea Protein Isolate is the no-frills workhorse of clean plant protein. Certified USDA Organic, non-GMO, and gluten-free, it contains exactly one ingredient — organic pea protein isolate — with no added flavors, sweeteners, or fillers. Each scoop delivers 20 grams of protein with a complete amino acid profile, making it an ideal base for anyone who wants full control over what goes into their shake. The unflavored format means you can add it to smoothies, oatmeal, or baked goods without altering the taste profile.

The texture is fine and powdery, which some users find mixes better with a frother or blender than a shaker bottle alone. When mixed with almond milk or added to a fruit smoothie with banana, pineapple, and berries, the pea taste becomes neutral and pleasant. Several reviewers note that it takes a few servings to acquire the taste when mixed with just water, but once you find your preferred combination — orange juice, chocolate milk, or nut butter — it becomes a reliable daily staple. The 2-pound container is compact but the screw-cap lid keeps the powder fresh and secure.

The biggest advantage of Nutricost is its cost-effectiveness. At this price point for organic, third-party-tested pea isolate, it is one of the most affordable clean options available. The trade-off is that it lacks any added digestive enzymes or probiotics, so some users may experience bloating if they are not used to pea protein. Also, the unflavored nature means you will need to add your own flavorings if you want something drinkable on its own. For the budget-conscious buyer who prioritizes purity over convenience, this is a smart choice.

Norcal’s Organic Peanut Butter Protein Powder takes a different approach — instead of a multi-ingredient protein blend, it is simply organic defatted peanut flour from Spanish peanuts grown on Southwest Texas organic farms. With 11 grams of protein per serving and only 3 grams of fat, it is an excellent low-calorie alternative to traditional peanut butter for anyone watching their fat intake. The powder is mechanically processed without solvents, keeping it vegan-friendly and retaining the natural peanut flavor without any additives.

This is not a standalone shake powder — it works best as a mix-in. Users add it to chocolate milk, smoothies, zero-sugar Greek yogurt, oatmeal, or even sprinkle it on rice cakes for a protein boost. One reviewer combines it with Norcal’s pea protein and Hershey’s Special Dark syrup for a homemade peanut butter cup shake. The peanut flavor is authentic and fresh, with no off odors or stale notes. For those on fat-restricted diets (such as post-gallbladder surgery), this provides the taste of peanut butter without the high fat content.

The main limitation is the protein content — 11 grams is lower than most dedicated protein powders, so you will likely need to combine it with another protein source if muscle building is your primary goal. Also, the bag format is functional but not as convenient as a tub for scooping. However, for the price and purity, it is an unbeatable way to add real peanut flavor to your meals without any sugar, additives, or artificial ingredients. If you love peanut butter but want a cleaner profile, this is your go-to.
