Question 1

What is Protein Yeast?

Accepted Answer

Protein Yeast (also called 'Proty') is an inactivated form of Saccharomyces cerevisiae — the same species used in bread and beer, but grown specifically as a nutritious food ingredient. Unlike active yeast, it won't leaven bread. It's deactivated with heat, then dried into flakes, granules, or powder with a savory, umami flavor.

Question 2

Is it the same as brewer's yeast or baker's yeast?

Accepted Answer

No. All three come from S. cerevisiae, but they're very different products. Baker's yeast is active and used to make bread rise. Brewer's yeast is a byproduct of brewing beer and can be quite bitter. Protein Yeast (nutritional yeast) is grown specifically as a food — it's deactivated, mild in flavor, and formulated to maximize nutrition.

Question 3

What does Protein Yeast taste like?

Accepted Answer

Savory, nutty, and cheesy — like a mild parmesan without any dairy. It has an umami depth that makes foods taste richer and more satisfying. Most people find it surprisingly delicious on first taste.

Question 4

Is Protein Yeast the same as nutritional yeast?

Accepted Answer

Yes — Protein Yeast is our brand name for fortified nutritional yeast. We use the name 'Protein Yeast' to highlight what makes it remarkable: it's one of the few complete plant proteins that contains all 9 essential amino acids.

Question 5

What nutrients does Protein Yeast contain?

Accepted Answer

Per 2-teaspoon (5g) serving: 20 calories, 3g protein, 0g fat, 2g carbs, 0g sugar. It's also fortified with B vitamins — delivering 313% DV of B12, 246% DV of riboflavin (B2), 212% DV of B6, and 109% DV of niacin (B3). It also contains trace minerals like zinc, selenium, and manganese.

Question 6

Is Protein Yeast a complete protein?

Accepted Answer

Yes. Unlike most plant proteins, Protein Yeast contains all 9 essential amino acids your body cannot produce on its own. This makes it a complete protein comparable to animal sources like meat and dairy.

Question 7

How does it help with B12?

Accepted Answer

Fortified Protein Yeast contains synthetic B12 added during manufacturing. Just 2 teaspoons provides 313% of the Daily Value — making it one of the most efficient dietary sources of B12 available to vegans and vegetarians.

Question 8

Can it help lower cholesterol?

Accepted Answer

Research suggests the beta glucan in nutritional yeast may help lower total cholesterol levels. In one 8-week study, men with high cholesterol who took 15g of yeast-derived beta glucan daily saw a 6% reduction in total cholesterol.

Question 9

Does it support the immune system?

Accepted Answer

Yes. Protein Yeast contains beta glucan and alpha mannan — carbohydrates that research shows may activate immune cells and support the gut microbiome. Animal studies show antibacterial and antifungal benefits, though more human research is ongoing.

Question 10

How much should I use per day?

Accepted Answer

A typical serving is 2–4 teaspoons (5–10g). It's safe to use up to several tablespoons (10–30g) per day. Most people start with 2 teaspoons on one meal and increase from there.

Question 11

How do I use it?

Accepted Answer

Sprinkle it on anything savory: pasta, popcorn, soups, stews, salads, grain bowls, roasted vegetables, scrambled eggs, pizza. You can also stir it into sauces as a thickener or add it to smoothies for extra protein.

Question 12

Can I cook with it?

Accepted Answer

Yes, but add it toward the end of cooking. High heat won't destroy the protein, but prolonged heat can degrade some B vitamins. It's best used as a finishing seasoning rather than cooked into dishes for extended periods.

Question 13

How should I store it?

Accepted Answer

Store in a cool, dark place away from moisture and direct sunlight. Seal the container tightly after each use. When properly stored, Protein Yeast is shelf-stable for up to 2 years.

Question 14

Is it safe for everyone?

Accepted Answer

Protein Yeast is generally considered safe for most people. However, anyone with a known yeast allergy should avoid it. Those with an MTHFR gene mutation may want to choose unfortified varieties, as fortified versions contain added folic acid.

Question 15

Is it gluten-free?

Accepted Answer

Yes. Protein Yeast is naturally gluten-free. Our product is certified gluten-free and processed in a dedicated gluten-free facility.

Question 16

Is it vegan and dairy-free?
