Single-source pea and hemp powders are a straightforward way to add plant protein without blends or added nutrients. This review looks specifically at Anthony’s Premium Pea Protein (a 100% pea protein isolate) and Manitoba Harvest Hemp Yeah! Organic Protein Powder (a hemp-based single-source powder offered in multiple flavors). Both target vegans, people avoiding dairy, and anyone who wants a minimal-ingredient protein boost.
My assessment is grounded in manufacturer specs (serving sizes, protein per scoop, calories, certifications), aggregated user feedback about taste and texture, and direct comparisons between the two product entries in the research brief. I focus on measurable points you can use to choose: grams of protein per scoop, calories, packaging options, certifications, and reported texture/taste issues.
Bottom line: Anthony’s pea isolate is the lean, pure protein option (24 g protein, ~120 calories per 30 g scoop) if you prioritize protein density and ingredient purity; Manitoba Harvest’s hemp powder is nutritionally interesting for its omega-3/6 profile and flavor options but delivers slightly less protein per scoop (20 g) and can cost more depending on size and flavor. Read on to see which fits your routine.
Protein per Scoop, Calories, and Nutrient Differences
Anthony’s Premium Pea Protein lists a 30 g scoop with 24 g of protein and about 120 calories; it’s a pea protein isolate so protein density is high. Manitoba Harvest’s Hemp Yeah! is 30 g per scoop with about 20 g of protein and 120–160 calories depending on flavor — flavored versions add calories. Hemp brings more fats, specifically omega-3 and omega-6 fatty acids, while Anthony’s also contributes minerals (phosphorus, calcium, magnesium, potassium) per the manufacturer data.
If your priority is maximizing grams of protein while keeping calories low, Anthony’s has the edge by delivering 24 g protein at ~120 calories. If you want added essential fatty acids and a broader micronutrient profile, the hemp powder's omega fatty acids are a real advantage.
- ✅ Anthony’s: 24 g protein / ~120 kcal (30 g scoop) — higher protein density.
- ✅ Manitoba Harvest: 20 g protein / 120–160 kcal, richer in omega‑3 & omega‑6.
- ❌ Hemp: lower protein per scoop vs the pea isolate; flavored versions increase calories.
Mixability, Flavor Options, and Mouthfeel
Anthony’s is unflavored and praised for mixing well into smoothies, but several users note a slightly gritty or chalky texture when not blended thoroughly. That lines up with common experiences of pea isolates: they’re neutral but can be texturally noticeable in thin liquids.
Manitoba Harvest offers unsweetened, vanilla, and chocolate flavors; user feedback in the brief specifically praises the chocolate for being "rich and satisfying." The hemp powder's nutty profile and flavoring options make it easier to drink straight or in shakes, though that comes with higher calories in flavored versions.
- ✅ Anthony’s: neutral taste—flexible in recipes; good mixability in smoothies.
- ✅ Manitoba Harvest: better immediate flavor options (chocolate especially), more palatable on its own.
- ❌ Anthony’s: slight chalky/gritty texture reported by some users unless well blended.
Ingredients, Certifications, and Who Should Use Each
Anthony’s Premium Pea Protein is 100% vegetable pea protein isolate with no additives, fillers, or preservatives—certified gluten-free, non-GMO, and vegan. That simplicity is valuable if you want a bare-minimum ingredient list. Manitoba Harvest’s Hemp Yeah! is organic, non-GMO, and vegan; it also brings the benefit of naturally occurring omega fatty acids.
From an allergen and dietary standpoint both are vegan and non-GMO; Anthony’s may be preferable if you need minimal ingredients, while Manitoba Harvest is attractive if organic certification and omega fats matter to you.
- ✅ Anthony’s: 100% pea protein isolate; gluten-free, non-GMO, vegan.
- ✅ Manitoba Harvest: organic and non-GMO; includes omega‑3/omega‑6.
- ❌ Neither is dairy-based — not a con for vegans, but if you want a blended complete profile you may need to combine or choose a blend product.
Packaging, Pricing, and Practical Uses
Packaging options: Anthony’s comes in 2‑ and 5‑pound tubs; Manitoba Harvest in 16‑ounce and 24‑ounce containers. Price ranges from the brief: Anthony’s roughly $20–$35 depending on size; Manitoba Harvest roughly $15–$25 depending on size and flavor. That means per-pound economics will vary — Anthony’s larger tubs favor higher-volume users, while Manitoba Harvest's smaller jars can be convenient for trying flavors.
Use cases: Anthony’s is best for adding straight protein to smoothies, baking, or recipes where you want minimal flavor impact. Manitoba Harvest suits those who want a nutty hemp flavor and the nutritional benefit of omegas, and who value organic certification or flavored options.
- ✅ Anthony’s: better per‑scoop protein for athletes or those tracking macros closely.
- ✅ Manitoba Harvest: better if you want omega fats or flavored options without dairy.
- ❌ Manitoba Harvest: some users note it's pricier at certain sizes/flavors.
How these compare to other plant-protein approaches
If you’re choosing between a single-source product and blends (pea+rice, mixed plant blends), single-source powders keep ingredients simple but may require pairing to reach a complete amino-acid profile in a single scoop.
- Anthony's Premium Pea Protein — best for pure protein density, few ingredients, and larger tub sizes for frequent users.
- Manitoba Harvest Hemp Yeah! Organic Protein Powder — best for omega fatty acids, organic certification, and flavor variety (unsweetened, vanilla, chocolate).

Quick take
- ✅ Pure protein option: Anthony’s delivers 24 g protein per 30 g scoop and a minimal ingredient list.
- ✅ Nutrient diversity: Manitoba Harvest adds omega‑3/omega‑6 and organic certification plus flavor options.

Ideal buyers
If you want a single-ingredient, high‑protein powder to mix into smoothies, baking, or meal-replacement shakes, Anthony’s Premium Pea Protein is a strong choice. If you want plant protein plus omega fatty acids, organic certification, and pre-flavored options for better straight-mix palatability, Manitoba Harvest is appropriate.
When to look elsewhere
Avoid single-source pea or hemp powders if you need a complete amino-acid profile in a single scoop (consider blended plant proteins) or if you are sensitive to grainy textures — pea isolates can be slightly chalky unless blended into thicker shakes.
