Dave's Killer Bread Powerseed: 5g Protein per Slice, Labelgrade B+ (82/100)
B+ 82 / 100 — The highest-protein and highest-fiber mass-market organic bread on the US shelf. Sweetened with organic fruit juice instead of cane sugar — a real differentiator in the bread category where added sugar is the norm. Five-seed mix (flax, sunflower, pumpkin, sesame x2) contributes both protein and ALA Omega-3.

Dave’s Killer Bread Powerseed delivers 5 g of protein and 6 g of fiber per 45 g slice for 110 calories, with 2 g of sugar that comes from fruit juice rather than added cane sugar (USDA FDC 2490632). For a bread, that’s a standout line: roughly 11 g of protein per 100 g and a third of the day’s fiber in one slice. It earns a B+ (82/100) — perfect marks on fiber and saturated fat, near-perfect on sugar — held just out of the A range by 150 mg of sodium per slice and protein math that, while high for bread, is still modest next to a dedicated protein food.
Why the B+
| Dimension | Grade | Score | Why |
|---|---|---|---|
| Protein density | C+ | 67 / 100 | ~11 g per 100 g — high for the bread aisle, modest against protein-first foods. The per-slice figure (5 g, or 10 g in a sandwich) is the number that matters in practice |
| Ingredient quality | B | 78 / 100 | Every line is organic and recognizable — whole wheat, a seven-component seed mix, fruit juice. Vital wheat gluten and added oat fiber keep it from a top grade |
| Sugar load | A+ | 95 / 100 | 2 g sugar, 0 g added — all of it from pear/peach/pineapple juice. Most commercial bread leans on cane sugar or HFCS, so this is a real category win |
| Saturated fat | A+ | 100 / 100 | 0 g. The 2 g of total fat is seed-derived (flax, sunflower, pumpkin), not added oil |
| Sodium | C+ | 65 / 100 | 150 mg per slice (~333 mg/100 g) — the one genuine ding, and 300 mg once you build a two-slice sandwich |
| Fiber | A+ | 100 / 100 | 6 g per slice — exceptional. Whole wheat, the seed mix, and a dedicated oat-fiber ingredient stack up |
The two grades doing the most work are at opposite ends. Fiber is a clean A+ that most bread can’t touch, and it’s earned three ways, not faked with a single isolate. The C+ on protein density isn’t a knock on the recipe — it’s the honest ceiling of all bread, which is a carbohydrate food first. The realistic lever for a shopper is sodium: 150 mg a slice is fine occasionally and adds up if Powerseed is your daily sandwich base.
The protein-and-fiber-forward bread, honestly
If you’re shopping bread for protein, calibrate expectations: a slice gives 5 g, a sandwich 10 g — meaningful, but you still need a real filling to get to a high-protein meal. Where Powerseed actually earns its keep is the combination. It pairs that above-average protein with 6 g of fiber and zero added sugar in the same slice, and that trio is genuinely hard to find together in the bread aisle, where seeded loaves often smuggle in cane sugar and high-fiber claims lean on a lone added isolate.
The 18 g of carbs per slice also read differently because of the fiber: 6 of those 18 grams are fiber, so the slice digests slower and steadier than a refined-flour equivalent with the same carb count. That’s the practical case for this bread over a standard loaf — not that it’s a protein source on its own, but that it makes the bread part of a meal pull more weight nutritionally.
What the seed mix actually does
The Powerseed mix is seven of the ingredient list’s lines — whole and ground flax, rolled oats, sunflower, pumpkin, and two sesame varieties — and it’s doing three jobs at once. It contributes a slice of the protein (seeds are protein-dense per gram), most of the 2 g of fat as unsaturated and ALA omega-3 from the flax and pumpkin, and a chunk of the fiber. It’s also why the loaf eats the way it does: the visible seeds give a dense, nutty crumb with real chew, the opposite of airy sandwich bread. Ground flax matters too — whole flax seeds often pass through undigested, so milling part of it is how you actually absorb the omega-3 rather than just see it on the label.
Powerseed vs. a standard white bagel
The cleanest contrast for what whole-grain seeding buys you is a refined-flour bread at the same protein. Thomas’ Plain Mini Bagels land at 5 g of protein per 43 g bagel (11.6 g per 100 g) — essentially the same protein as a Powerseed slice — but get there from unbleached enriched (refined) flour plus added wheat gluten, and the rest of the profile diverges sharply:
| Per serving | Powerseed (45 g slice) | Thomas’ Plain Mini Bagel (43 g) |
|---|---|---|
| Protein | 5 g | 5 g |
| Fiber | 6 g | 2 g |
| Sugar | 2 g (juice, 0 g added) | 3 g (added) |
| Sodium | 150 mg | 190 mg |
| Base | organic whole grain + seeds | refined enriched flour + dough conditioners |
| Labelgrade | B+ (81) | B- (74) |
Same protein, different bread. Powerseed triples the fiber, drops the sodium, and swaps added sugar for fruit juice, while the bagel’s deck is enriched flour plus monoglycerides, gums, and preservatives. That gap — not the protein number — is what the seven-point Labelgrade spread (81 vs. 74) is measuring, and it’s the case for whole-grain seeding over a standard white base in one comparison.
Where it sits in the Dave’s lineup
Powerseed is the seed-forward, fiber-maximizing member of the family, distinct from siblings like 21 Whole Grains and Seeds (broadest grain mix), Good Seed (similar build, lighter taste), and White Bread Done Right (Dave’s lower-fiber white variant). There’s also a Thin-Sliced Powerseed using the same recipe in a roughly half-weight slice — better for calorie control, but proportionally less protein and fiber per slice, so the standard-thickness loaf on this page is the better protein- and fiber-per-slice pick. Formulas and slice weights vary across the line, so check the actual loaf label.

Frequently Asked Questions
How much protein is in Dave's Killer Bread Powerseed?
5 g per 45 g slice (USDA FDC 2490632) — about 11 g per 100 g. The wheat carries most of it, but the seed mix (flax, pumpkin, sunflower, sesame) and the added vital wheat gluten push it past plain whole-wheat. A two-slice sandwich is 10 g of protein from the bread alone, before any filling.
What sweetens it, if not cane sugar?
Organic fruit juices — a blend of pear, peach, and pineapple. That accounts for the 2 g of sugar per slice and is why the label reads 0 g added sugar: there is no cane sugar, honey, or HFCS in the deck. In a bread aisle where 2–3 g of added sugar per slice is the norm, juice-only sweetening is the genuine differentiator, not a marketing flourish.
Why is the fiber so high for a bread — 6 g a slice?
Three stacked sources. The base is 100% whole wheat (flour plus cracked wheat, so the bran stays in), the Powerseed mix adds flax, oats, and seed hulls, and there's a dedicated organic oat fiber ingredient on top. Most whole-wheat loaves manage 2–3 g; Powerseed's 6 g is a third of the 25 g daily target in a single slice.
Where does the fat come from, and is it the good kind?
Just 2 g per slice, almost entirely from the seeds, with 0 g saturated. The flax and pumpkin seeds bring ALA omega-3 and the sunflower and sesame add unsaturated fat — so the small fat figure here is seed-derived, not added oil or shortening.
Is the vital wheat gluten a problem?
Only if you can't have gluten. It's the 9th ingredient — concentrated wheat protein added for rise and a less crumbly crumb in a dense whole-grain loaf, and it's part of why the slice hits 5 g of protein. Anyone with celiac disease or a wheat allergy must avoid this bread entirely; for everyone else it's a functional, food-derived ingredient.
How much sodium per slice, and does it add up?
150 mg per slice — about 7% of the FDA daily limit, and the main reason the grade is a B+ rather than higher. A sandwich is two slices, so 300 mg before fillings, and seeded sandwich breads run saltier than they taste. Manageable in a balanced day, but worth tracking if you eat it daily.
Is it 'high in protein' by FDA rules?
No — 5 g per slice is 10% of the 50 g Daily Value, which earns 'good source of protein' but not 'high in protein' (that needs 20% DV / 10 g). A two-slice sandwich clears the higher bar on bread alone, which is unusual in the category.
