How to Eat Brewers Yeast for Grey Hair

Brewer's yeast is the fungus Saccharomyces cerevisiae and a common component in the fermentation of beer. While not an essential nutrient needed by the body, the University of Maryland Medical Center reports this yeast is a vital source for B-complex vitamins. Two of those vitamins, B5 and B6, can help prevent graying in hair. B5 may work to keep gray hair for forming and B6 helps the body manufacture melanin to sustain natural hair color. As a dietary supplement, brewer's yeast may also help control blood sugar levels and reduce body fat and cholesterol.

Step 1

Purchase brewer's yeast as a powder, tablet or capsule supplement. The University of Michigan recommends high-quality brewer's yeast powder in bulk format to increase your intake of chromium. If you decide on the tablet or capsule instead, read the dosage instructions provided with the product. Try to take at least 15 to 30g a day.

Step 2

Mix 1 tbsp. of brewer's yeast into a glass of water every morning. Initially, it may take your body time to adapt to the yeast. Start at 1 tbsp. and build on the dosage until you reach 2 tbsp. a day. If necessary, mix with juice to improve the taste. The yeast will be bitter. This bitterness indicates that the powder contains biologically active chromium. If it is not bitter, it may not be high-quality.

Step 3

Mix the powder into other foods if you cannot tolerate the drink. For example, you can mix it into low-fat yogurt or sprinkle it over hot cereal.
