Analysis

The powder delivers 14 g of protein, 585 mg potassium, 220 mg phosphorus, and 65 mcg selenium. It also provides meaningful folate and several B vitamins, making general nutrient coverage its clearest strength.

Potassium supports the formula's broad nutritional value, while selenium and phosphorus are present in useful but not highly targeted amounts. The chemical forms of these minerals are not disclosed, leaving absorption and source quality uncertain.

For general health, the food-based mix covers several nutritional pathways in a coherent way. Its immune and heart-health fit is more modest because it lacks several common targeted nutrients and provides only part of a full daily potassium intake.

Who is it for
  • Adults seeking food-based B vitamins and minerals
  • People wanting protein with broad nutrient coverage
  • Users comfortable with brewer's yeast powder
Best for
  • General nutritional support
  • Adding potassium and B vitamins to a diet
  • Whole-food-style powder routines

Pros

  • Provides 14 g of protein
  • Meaningful potassium and phosphorus amounts
  • Supplies selenium, folate, and multiple B vitamins
  • Broad, coherent nutrient profile

Cons

  • Mineral chemical forms are not disclosed
  • Two-scoop powder serving may be inconvenient
  • Only modest fit for focused immune or heart support
  • Weak value when purchased for selenium or phosphorus alone

Warnings

  • The 585 mg potassium serving may not suit people who must medically restrict potassium
  • Brewer's yeast is the core ingredient and is unsuitable for users who need to avoid yeast
  • The powder contains 12 g carbohydrate per serving, which matters for carbohydrate-restricted plans

Nutrient quality

85 Highest impact

Meaningful protein and a broad natural micronutrient profile provide useful coverage. Unspecified nutrient forms limit absorption detail.

Ingredient transparency

78 High impact

The extensive nutrient profile is fully quantified. Usage details, non-active ingredients, and specific nutrient forms are incomplete.

Customer satisfaction

68 High impact

The aggregate rating is mixed to favorable and backed by a large review volume. No specific comments are available to assess recurring problems or real-world fit.

Value for money

68 High impact

Broad nutrient density provides real formula value. The premium daily cost limits affordability.

Brewer's yeast supplies protein, B vitamins, selenium, phosphorus, and potassium in a food-based powder. The mix can contribute to daily nutrient coverage and energy metabolism.

Selenium and several B vitamins are meaningful, while many minerals appear only at modest food-level amounts. The selenium form and the natural variability of the yeast nutrients are not disclosed.

The food powder provides potassium and B vitamins that offer modest cardiovascular support. It provides 585 mg of potassium with folate, B vitamins, selenium, and protein for the stated purpose.

Potassium remains well below a full daily target and no primary lipid or cardiac-energy active is present. Its limited cardiovascular focus remains the main practical trade-off.

Selenium provides some antioxidant support, while protein and B vitamins contribute to general nutritional status. The powder lacks vitamin C and vitamin D and supplies only a small zinc amount.

Selenium is present at a maintenance level, but its chemical form is not disclosed. The food-based nutrient profile is more suitable for broad nutrition than targeted immune support.

Report overview
Potassium · 585 mg OverallScore59
F Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyB+ Value

The food-based powder supplies a high amount of potassium along with protein and B vitamins. Its natural source does not identify a specific potassium compound, though the listed nutrient amount strongly implies elemental potassium. The serving cost is reasonable for an effective dose, but two scoops may be less convenient than a capsule or tablet.

View ingredientView products
Phosphorus · 220 mg OverallScore43
F Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyF Value

The phosphorus amount falls within a targeted supplemental range for bone support. Its source compound is not disclosed, which leaves its biological quality uncertain. Two scoops are manageable, but the cost per serving offers weak value compared with the collection.

View ingredientView products
Selenium · 65 mcg OverallScore36
F Active Ingredient Quality & BioavailabilityB Dose, Safety & Label TransparencyF Value

The 65 mcg serving provides a modest maintenance amount but falls below common targeted dosing. The label lists selenium without identifying its chemical form or carrier. No compound, isomer, source, or branded ingredient is disclosed. Standardized cost for a full selenium dose is high, although the food powder provides nutrients beyond selenium.

77 Performance

100% Natural Whey Protein Isolate Natural French Vanilla

Bluebonnet
A large whey-isolate serving offers concentrated, complete protein with less carbohydrate than the brewer’s yeast. The original remains broader for B vitamins, selenium, potassium, and phosphorus, so the improvement applies mainly to protein nutrition.
75 Performance

100% Whey Protein Isolate Alpine Vanilla

NutraBio
A substantial whey-isolate serving provides more protein in a leaner format. Mineral forms and complete ingredients are missing, and the narrow protein powder does not reproduce the original micronutrient profile.
72 Performance

Whey Factors Natural Double Chocolate Flavor

Natural Factors
A meaningful whey-concentrate serving offers complete dairy protein in a conventional powder. It provides less protein than some alternatives and does not match the brewer’s yeast for B vitamins, selenium, potassium, or phosphorus.
80 Budget

100% Natural Whey Protein Isolate Natural Original Flavor

Bluebonnet
A lower serving cost nearly doubles the protein contribution with a lean whey-isolate source. B vitamins, selenium, and the original’s substantial potassium and phosphorus are not matched, so the savings favor protein rather than whole-food nutrient breadth.
75 Budget

Forti-Flax

Barlean's
A much lower recurring cost provides a simple ground-flax food with potential fiber and fatty-acid value. Those components are not quantified, and the product lacks the original’s protein, B vitamins, selenium, and potassium depth.
75 Budget

Whey Factors Natural Strawberry Flavor

Natural Factors
A slightly lower serving cost provides a meaningful whey-protein amount with some potassium and phosphorus. The formula gives up the original’s B vitamins and selenium, while concentrate is less lean than isolate.
75 Value

Whey Factors Natural Double Chocolate Flavor

Natural Factors
A lower recurring cost provides a meaningful complete-protein serving with modest potassium and phosphorus. The original has much broader micronutrient coverage, so value is stronger only for users prioritizing protein.
78 Value

Classic Whey Chocolate Milkshake

NutraBio
A lower serving cost provides substantial whey protein with modest potassium and phosphorus. Cholesterol remains a trade-off and the formula lacks the brewer’s yeast B vitamins and selenium, but protein value is favorable.
76 Value

100% Natural Whey Protein Isolate Natural French Vanilla

Bluebonnet
A larger whey-isolate serving delivers concentrated protein at a moderately higher recurring cost. The lean protein yield may justify that cost for protein-focused use, but it does not reproduce the original’s whole-food nutrient breadth.
