Low-sodium peanut butter is not simply peanut butter with a little less salt. It’s a complete rethinking of how peanut flavor is delivered. The majority of conventional peanut butters pack 100–150 mg of sodium per serving, and the “reduced sodium” versions often replace salt with sugar or palm oil, masking the very problem you are trying to solve. The real low-sodium game lives in single-ingredient powdered peanut butters and unsalted natural spreads that strip away everything but the roasted nut.
I’m Emma — the founder and writer behind Baby Bangs. I have spent the last three years reverse-labeling every peanut butter jar and pouch on Amazon to find the handful that actually deliver on a sodium-free, additive-free promise without tasting like cardboard.
Whether you are managing blood pressure, following a renal-friendly diet, or just tired of hidden salt in your morning toast, this guide filters out the noise to reveal the actual best low-sodium peanut butter options you can buy right now.
How To Choose The Best Low-Sodium Peanut Butter
Most shoppers grab the first “unsalted” jar on the shelf without checking for added oils, sugar, or stabilizers that sneak sodium back in. A true low-sodium peanut butter requires zero milligrams of sodium per serving and nothing beyond roasted peanuts. Here is how to identify the real thing.
Look for the single ingredient
The best low-sodium peanut butter has exactly one ingredient: peanuts. If the label lists salt, sugar, palm oil, or “natural flavors,” it is not a clean sodium-free option. Powdered peanut butters are currently the only format that consistently delivers a pure peanut ingredient list without exceptions.
Check the sodium per serving
Target zero milligrams of sodium. Even “unsalted” spreads sometimes contain trace sodium from added emulsifiers or natural flavor compounds. A serving size of two tablespoons should show 0 mg sodium on the label. If you see 5 mg or more, the brand likely uses a sodium-containing additive.
Decide between powdered and traditional
Powdered peanut butter removes most of the fat and all of the sodium, yielding a lower-calorie protein boost that mixes into smoothies, oatmeal, or sauces. Traditional unsalted creamy peanut butter retains the full fat profile and works best for spreading on toast or eating by the spoonful. Your choice depends on whether you prioritize convenience and macros or texture and mouthfeel.

In‑Depth Reviews
1. It’s Just! Peanut Butter Powder – 32oz
This powdered peanut butter from 138 Foods delivers exactly one ingredient — roasted non-GMO peanuts — with zero milligrams of sodium per serving. Each 12 g scoop provides 6 g of plant protein and just 1 g of net carbs, making it one of the leanest low-sodium options available. The powder mixes into smoothies, oatmeal, and baked goods without clumping, and the resealable bag keeps freshness locked between uses.
Third-party testing for heavy metals, gluten, and microbiology is performed on every batch, with results available online for full transparency. Users consistently report a clean, subtle roasted peanut flavor that complements chocolate protein powder or a simple banana smoothie without adding sweetness or salt.
The only downside is the lack of a scoop inside the bag, but the 32-ounce volume delivers 76 servings, which brings the per-use cost below most single-ingredient powdered brands. If you want one pantry staple for low-sodium baking, shakes, and dressings, this is the strongest all-around performer tested.
Why it’s great
- Zero sodium, zero sugar, single ingredient peanut powder.
- Third-party tested batch-to-batch for heavy metals and gluten.
- Versatile — mixes into hot and cold liquids without clumping.
Good to know
- No scoop included in the bag.
- Subtle peanut flavor may not satisfy those wanting a strong roasted taste.
2. Organic Powdered Peanut Butter (Naked) – 24oz
Naked’s organic powdered peanut butter offers 8 g of protein per serving with zero milligrams of sodium and no additives. The organic certification covers the entire supply chain — peanuts grown on US farms, dry-roasted, and ground into powder without any preservatives, sugar, or salt. Each serving delivers 60 calories and 5 g of carbs, providing a slightly higher protein density than most competitors in the organic powdered segment.
Third-party heavy metal testing is standard for this brand, and the 24-ounce bag yields 45 servings. The powder blends seamlessly into protein shakes and pancake batter, though its texture is slightly finer than the non-organic Naked PB, resulting in a smoother reconstituted spread if you add water.
The main trade-off is the price per ounce relative to non-organic powders, but for buyers committed to organic sourcing and maximum protein per scoop, this Naked variant justifies the premium. It is the smart choice for anyone who wants verified organic peanuts without sacrificing protein content.
Why it’s great
- USDA Organic peanuts with no salt or additives.
- 8 g protein per serving — highest among tested powders.
- Third-party tested for heavy metals and impurities.
Good to know
- Higher cost per serving than non-organic alternatives.
- Bag size yields fewer servings than the 2 lb non-organic option.
3. PB2 Pure Organic Powdered Peanut Butter – 24oz
PB2 Pure is the only USDA Certified Organic powdered peanut butter on this list that also carries Non-GMO Project Verified and kosher certifications. With one ingredient — organic roasted peanuts — it delivers 6 g of protein and zero milligrams of sodium per serving while removing 90% of the fat found in traditional peanut butter. The 24-ounce resealable jar format is pantry-friendly and keeps the powder fresh for months.
The powder reconstitutes into a creamy spread within seconds and works cleanly in baked goods and oatmeal. Because it only contains peanuts, the flavor profile is straightforward and unsweetened, which pairs well with chocolate protein powder or cinnamon in smoothies. This is the most lab-tested option in the lineup, with batch-level transparency for purity.
For keto and vegan bakers who prioritize organic certification above raw protein density, PB2 Pure hits the right balance.
Why it’s great
- USDA Organic and Non-GMO Verified in a single jar.
- 90% less fat than traditional peanut butter.
- Resealable jar stays fresh longer than stand-up pouches.
Good to know
- 6 g protein per serving is slightly lower than the Naked organic.
- Jar volume yields 24 servings — smallest total quantity on this list.
4. Naked PB Powder (2 lb) – 32oz
Naked PB’s 2-pound bag is the volume champion of single-ingredient powdered peanut butters, providing 76 servings per container. Each serving delivers 7 g of protein, 3 g of carbs, and 50 calories with zero milligrams of sodium and no sugar. The peanuts are grown on US farms, non-GMO, and the powder is independently third-party tested for heavy metals.
The larger bag size makes this the most economical option for frequent users who add peanut powder to post-workout shakes, overnight oats, or savory sauces. The texture is coarser than the organic Naked variant, which some users prefer for a more rustic peanut crumble in baking applications.
The downside is the packaging — a large stand-up pouch without a scoop. Once opened, the bag requires careful resealing to maintain freshness. For users who burn through powdered peanut butter quickly, the 76-serving count outweighs the convenience trade-offs.
Why it’s great
- 76 servings per bag — best cost-per-serving in this lineup.
- US-grown non-GMO peanuts, heavy metal tested.
- Lowest carb count per serving among tested powders.
Good to know
- No scoop and the pouch can be difficult to reseal airtight.
- Slightly coarser grind than the organic version.
5. 365 Unsalted Creamy Peanut Butter (2-pack)
365 by Whole Foods Market offers the only traditional-style spread on this list — a creamy unsalted peanut butter with zero milligrams of sodium per two-tablespoon serving. The two-pack provides 52 total ounces, and the ingredient list excludes hydrogenated fats, high fructose corn syrup, and bleached flour. Each serving delivers 8 g of protein with the full mouthfeel and fat content of a standard peanut butter.
The oil separation is typical for natural unsalted peanut butter, requiring a thorough stir before first use. Once mixed, the texture stays smooth and spreadable without added palm oil or stabilizers. This is the best option for anyone who wants a classic jarred peanut butter experience without the sodium.
The primary limitation is the lack of organic certification and the need to manage oil separation. For households that prefer the traditional spoon-and-spread format over powdered alternatives, this two-pack delivers the most volume per purchase in the traditional category.
Why it’s great
- Classic creamy texture with zero milligrams of sodium.
- Two-pack provides 52 ounces for pantry stocking.
- No hydrogenated fats or high fructose corn syrup.
Good to know
- Oil separation requires thorough stirring before each use.
- Not USDA Organic certified.
