For many millennia, yeast has been a significant component of the human diet, finding its place in staples like bread. In recent times, a distinct yeast variant known as nutritional yeast has garnered attention due to its rich nutritional profile. It is believed to enhance energy, fortify the immune system, and bring about additional health benefits. 

Notably, one of the major nutritional yeast benefits lies in its capacity to promote hair health. Let’s delve into the specifics of this remarkable ingredient and how it can benefit your hair.

What is Nutritional Yeast?

Nutritional yeast is derived from Saccharomyces cerevisiae, a specific yeast species. It’s important to distinguish it from another yeast variant known as brewer’s yeast, as these terms are sometimes used interchangeably. Nutritional yeast is cultivated on diverse sources, such as blackstrap molasses, sugar beets, or whey. Although it shares similarities with baking yeast, it undergoes a heating and drying process that deactivates it, setting it apart.

Nutritional Yeast Profile

Nutritional yeast stands out as a remarkable source of essential nutrients. Typically, a quarter-cup serving of nutritional yeast provides:

  • 8 g of protein
  • 60 calories
  • 3 g of dietary fiber
  • 9.70 mg of riboflavin (vitamin B2)
  • 17.60 micrograms of vitamin B12
  • 11.85 mg of thiamine (vitamin B1)
  • 5.90 mg of vitamin B6

Additionally, it contains vitamin B3, calcium, potassium and iron, further enriching its nutritional profile.

Benefits of Nutritional Yeast for Hair

When it comes to foods you can include in your diet to achieve strong and healthy hair, nutritional yeast is a strong contender. It offers a rich blend of amino acids and essential B vitamins. It is considered a complete protein, which means it contains eight essential amino acids, just like hemp and quinoa, ensuring a robust amino acid supply in your diet. Certain amino acids, specifically methionine, cysteine, and lysine, play crucial roles in fostering hair growth. These amino acids enhance hair shaft strength, aiding in moisture retention. 

Furthermore, nutritional yeast provides a wealth of crucial B vitamins, including the indispensable vitamin B7, known as biotin. These vitamins are instrumental in creating red blood cells, responsible for delivering oxygen and vital nutrients to hair follicles. Additionally, nutritional yeast is full of fiber, minerals, and antioxidants that are vital for sustaining healthy hair.

How to Use Nutritional Yeast?

Nutritional yeast is available in two forms: powder and flakes. It has a delectable flavor profile with nutty, savory, or even cheesy notes. People can creatively incorporate it as a seasoning in various dishes, including vegetables, pasta, and salads. Here are some ways to use nutritional yeast:

  • Sprinkle it over popcorn as a healthy alternative to butter or salt.
  • Use it to create a vegan-friendly cheese sauce.
  • Blend it into risotto in place of Parmesan cheese.
  • Incorporate it into vegan macaroni and cheese dishes.
  • Add it to scrambled eggs or a tofu scramble.
  • Stir it into creamy soups.
  • Mix it into nut roasts or stuffing recipes.

Nutritional Yeast Side Effects

While nutritional yeast has numerous advantages, it’s not a universal solution and may not be suitable for everyone. Research suggests that individuals with conditions such as glaucoma, inflammatory bowel disease (IBD), and hypertension should exercise caution and refrain from using nutritional yeast, as it could potentially exacerbate their symptoms. 

Those with yeast sensitivity or allergy should also steer clear of nutritional yeast to avoid adverse reactions. Moreover, some experts recommend that individuals at a higher risk of gout may find it prudent to avoid nutritional yeast.


Nutritional yeast is a powerhouse of nutrients, containing essential vitamins, minerals, and proteins. When it comes to hair health, its rich amino acid profile and the abundance of B vitamins, including biotin, make it a valuable addition to your diet. These components contribute to stronger hair, improved moisture retention, and overall hair growth support. 

Nutritional yeast’s versatility in flake or powder form allows it to enhance a variety of dishes. However, it’s worth noting that some individuals with specific health conditions or sensitivities should exercise caution with its consumption, as it may not be suitable for everyone.
