Is Vitamin B12 Important for Hair Growth?

When you start researching hair loss, it doesn’t take long before vitamins enter the conversation. One of the most commonly talked about? Vitamin B12.

But can low B12 actually affect your hair? And should you be paying attention to it if you’re noticing thinning or shedding?

Let’s break it down.

What Is Vitamin B12?

Vitamin B12 is an essential vitamin that helps your body function properly. It plays a role in energy production, red blood cell formation, nervous system health and overall cell function.

Your body doesn’t naturally produce vitamin B12 on its own, which means you need to get it through food or supplements.

Low levels of B12 can sometimes leave people feeling tired, foggy, weak or run down. And in some cases, it may also impact hair health.

What Does Vitamin B12 Have to Do With Hair?

Healthy hair growth relies on healthy blood flow and oxygen reaching the hair follicles.

Vitamin B12 helps your body produce red blood cells, which carry oxygen and nutrients around the body, including to your scalp and hair follicles.

When your body is low in B12, your follicles may not receive the support they need to function at their best. For some women, this can contribute to increased shedding or slower hair growth over time.

That being said, hair loss is rarely caused by one thing alone. Hormones, genetics, stress, illness, iron levels and other nutritional deficiencies can all play a role too.

If you’re concerned about sudden or ongoing hair loss, it’s always worth speaking with your doctor and requesting blood work to rule out any underlying deficiencies.

Signs You Might Be Low in B12

Some common symptoms associated with low vitamin B12 can include:

• Fatigue or low energy
• Brain fog
• Dizziness
• Weakness
• Tingling hands or feet
• Pale skin
• Increased hair shedding

Of course, these symptoms can be linked to many different things, so it’s important not to self-diagnose.

How can you increase your Vitamin B12 intake? Here are some foods Rich in Vitamin B12

Vitamin B12 is found mostly in animal-based foods.

Some common sources include:

• Eggs
• Beef
• Salmon
• Tuna
• Milk
• Cheese
• Yogurt
• Fortified cereals
• Fortified plant-based milks

Women following vegetarian or vegan diets may sometimes struggle to get enough B12 through food alone, which is why supplementation is occasionally recommended by healthcare professionals.
