Improve your hair: 14 delicious biotin-rich foods to add to your diet right now

Eat these great foods for healthier hair and skin

Hair loss is one the biggest fears among all men, affecting up to 70% of them. If you research hair loss, you will eventually come across the importance of biotin, which is one of the B vitamins. Studies have shown biotin’s ability to increase hair strength, thickness, and growth. Biotin also improves the health of nails and performs other critical functions in the body. For example, biotin plays a crucial role in specific metabolic and energy-generating pathways by helping break down carbs, proteins, and fats into usable energy. Biotin also helps regulate blood sugar, supports healthy skin, and assists in cell signaling.

Biotin is a water-soluble vitamin, meaning the body cannot store significant amounts, therefore it must be consumed regularly in the diet. The recommended daily intake (RDA) of biotin for most adults is 30 to 100 mcg. While supplements are always an option, it’s better to get you micronutrients through diet. Luckily, there are plenty of foods high in biotin. Consuming a variety of biotin-rich foods will help ensure adequate intake to support a healthy metabolism, energy generation, a full head of hair, and youthful skin. With that in mind, here are some of the foods high in biotin to help you maintain your luscious locks.

Eggs with yolk.

Egg yolks

Eggs are one of nature’s little packages of vital nutrients. For example, an egg is a complete source of protein, meaning it contains all essential amino acids. Egg yolks are also rich in vitamin D, a fat-soluble vitamin that plays important roles in bone health, along with iron, which helps transport oxygen in the blood to every cell and tissue in the body. Egg yolks are also rich in B vitamins, especially biotin, with 10 mcg of biotin (33% DV) per whole egg. It’s important to note that eggs must be cooked to capitalize on this biotin, as raw egg whites contain avidin, a protein that interferes with biotin absorption.

Salmon and other fatty fish are revered for their high omega-3 fatty acid content, which helps reduce inflammation in the body. Salmon is also a great source of biotin, with each 3-ounce serving of cooked salmon providing 5 mcg of biotin. Because salmon also contains healthy fats, it’s an excellent food for healthy skin and hair.

Brewer’s yeast, which is used to make bread and beer, contains a decent amount of biotin, as does nutritional yeast, a product used in many vegan cheeses and non-dairy substitutes. There is 21 mcg in every 2-tablespoon serving of nutritional yeast, for example. If you’re not sure how to use it, think of it somewhat like a Parmesan cheese substitute. Sprinkle it on salads, pasta dishes, soups, or even popcorn.

Pork chops


If you love the carnivorous part of your diet, you’re in luck. Meats such as hamburgers and pork chops are rich sources of biotin. A 3-ounce serving of either contains 13% of the DV, or 3.8 mcg, of biotin. Opt for lean meats to maximize the health benefits.

The majority of legumes, such as beans, lentils, peanuts, and soybeans, are a great source of biotin. They also provide complex carbohydrates, plenty of fiber, prebiotics, and iron. Peanuts and soybeans contain the most biotin among this group. For example, a 1-ounce (28 grams) serving of roasted peanuts contains nearly 5 mcg of biotin, which is 17% of the recommended daily value. When considering soybeans, there is a whopping 19.3 mcg of biotin (64% DV) per 3/4 cup.

Pan fried liver.


Although it’s not everyone’s cup of tea, liver is one of the best dietary sources of biotin because biotin is stored in the liver (in limited quantities since it’s a water-soluble vitamin). Cooked chicken liver is an extremely rich source of biotin, with an impressive 138 mcg per 3-ounce serving, which is equivalent to 460% of the DV. Cooked beef liver is a slightly less potent source of biotin, but still provides 31 mcg (103% DV) per 3-ounce serving. Liver can take some getting used to, with a prominent metallic flavor due to its high iron content. However, its nutritional benefits are enough to win over some initially reluctant eaters, so you might consider giving it a try.

Sunflower seeds

Sunflower seeds

Many people consider seeds to be superfoods, as they provide an array of key vitamins, minerals, and essential fats. Hemp seeds, for example, also provide a lot of fiber, and minerals such as calcium, magnesium, phosphorus, iron, zinc, and copper. Moreover, they are a rich source of biotin. Another good option for seed lovers is sunflower seeds, with each 1/4 cup (20 grams) serving of roasted sunflower seeds providing 2.6 micrograms of biotin, which is roughly 10% of the recommended daily value.

Sliced mushrooms.


Mushrooms provide you with antioxidants along with minerals like selenium and magnesium. They also contain biotin, with each cup of fresh button mushrooms providing 5.6 mcg. Consider adding mushrooms to salads, stir-fries, sandwiches, or hearty winter soups.

Fresh broccoli.


Though the biotin content in broccoli is fairly low — at 0.4 micrograms per half-cup — it’s such a powerhouse of other key nutrients like vitamin C, fiber, water, and calcium, that it never hurts to add it to your plate.

Sweet potatoes

Sweet potatoes are packed with nutrients such as vitamin A and beta-carotene, vitamin C, fiber, manganese, potassium, copper, and magnesium. They are also one of the best vegetable sources of biotin. There is 2.4 mcg (8% of the recommended daily value) of biotin per 1/2 cup of cooked sweet potato. Along with the vitamin A in sweet potatoes, which is also good for the eyes and skin, the biotin makes sweet potatoes a superfood for skin health. Enjoy sweet potatoes baked, microwaved, steamed, roasted, mashed, spiralized, grilled, or even riced. If you prefer less starchy root vegetables, carrots also contain a decent amount of biotin and plenty of vitamin A as well.

Tuna fish in oil

Tuna fish

Canned tuna is inexpensive and convenient. Moreover, it’s a good source of biotin. A 3-ounce can of tuna packed in water provides 0.6 micrograms of biotin. Canned tuna also provides nutrients like tryptophan, which can aid sleep and promote the production of serotonin, a feel-good neurotransmitter that elevates mood.

Whole almonds.


Almonds are a good source of biotin, with 1.5 mcg per quarter cup. Almonds also provide healthy monounsaturated fats and omega-3 fatty acids, which help reduce inflammation and support heart health. They also contain vitamin E, another essential nutrient for hair and skin health. To boost your biotin dose, consider pairing almonds with another biotin-rich food, such as oatmeal. If you prefer to go the trail mix route, combine almonds with peanuts, which provide about 0.8 mcg per serving.

Fresh spinach.

There are many health benefits to eating your leafy greens. From fiber and foods high in vitamin C to polyphenols and antioxidants, spinach is chock full of essential nutrients. It also provides 0.5 mcg of biotin per 1/2 cup of cooked spinach.

Cheeses with biotin.

Cheese and other dairy

Cheddar cheese is the best dairy source of biotin, with 0.4 mcg per 1-ounce serving. Milk and plain yogurt are also good sources. Foods with melatonin, such as milk can help regulate your sleep cycle to keep you from tossing and turning at night.

How do I know if I have a biotin deficiency?

Biotin deficiencies are extremely uncommon, so it’s likely that you don’t have to worry about this. The foods we listed above are in most people’s regular diet, making hitting your daily biotin goals rather effortless.

However, there is nothing wrong with keeping an eye out for any nutrient deficiency, including biotin. If you experience the following symptoms, your diet may be lacking in biotin.

  • Dry skin

Need to reduce your daily sugar intake? Eliminate these surprising foods
Sugar is sneaky, hiding itself in many surprising places (like these foods)
Bacon frying in pan

It's no surprise that we as a society are eating far too much sugar. On average, American adults consume around 77 grams of sugar per day. That's more than three times the USDA's recommended daily sugar intake. Sure, it's easy to point our fingers at the conveniently located candy bars in the checkout lane, or the super-sized sodas everywhere you turn. Easy-to-munch sugary snacks like cookies are far too easy to take advantage of. And those pretty little pastries with our morning coffee are obvious culprits, too.
What might not be so obvious, though, are the sneaky ways sugar makes itself at home in such a vast amount of the food we consume. Ice cream and candy, sure. But milk? Marinara sauce? What about those "healthy" foods with labels that read low-fat or low-sodium? We'll let you in on a little secret -- if they're cutting one ingredient, they're probably making up for it with sugar.
Sugar is sneaky, creeping into surprising foods and then disguising itself with an exotic name tag on the nutrition label. Common aliases include cane crystals, corn sweetener, corn syrup, crystalline, evaporated cane juice, fructose, fruit juice concentrates, and syrup, to name only a few!
So if you're trying to watch your sugar intake, the smartest thing you can do is read the label of everything you're bringing home from the grocery store, because that sugar will creep up out of nowhere if you aren't careful. To help you be better prepared, though, here is a list of foods sugar loves to hide in.

Yogurt has been living under the comfortable "health food" label for decades. And not without reason. Yogurt has some tremendous health benefits like probiotics and calcium. Unfortunately, it's also laden with sugar. Many common low-fat varieties contain up to 33 grams of sugar in one 8-ounce serving.

Your guide to the low-sodium diet (plus, a simple meal plan to follow)
A complete list of low-sodium foods for your diet
Canned soup is high in sodium.

Hypertension, also referred to as high blood pressure, affects nearly half of the adults in the U.S. The number of men that have hypertension is slightly higher than women, and if you are one of them, you may find your doctor recommending that you follow a low-sodium diet.
Although your body does need some sodium -- as it's an important electrolyte involved in muscle contractions, conducting electrical impulses in the heart, and regulating fluid balance -- the typical American diet is extremely high in sodium. Excess sodium contributes to high blood pressure and can tax the heart over time.
The Dietary Guidelines for Americans recommends adults limit their daily sodium intake to less than 2,300 mg per day, which is equal to one teaspoon of table salt. However, 97% of males aged 19 to 59 are exceeding the recommended intake for their age; they sometimes even reach twice the recommended limit.
A low-sodium diet deliberately limits the amount of sodium consumed each day and has been shown to effectively reduce blood pressure and improve heart function. It can be daunting to get started on a low-sodium diet, and it may feel like you have to give up some of your favorite foods.
The good news is that there are many delicious, nutritious foods you can still eat on a low-sodium diet, and you’re likely to feel so much better that any sacrifices will feel well worth it. Keep reading for our full guide containing everything you need to know about a low-sodium diet.

What is a low-sodium diet?
Sodium, which is essentially various forms of salt, is present naturally in certain foods like eggs and spinach. Still, the majority of the sodium we consume is added to processed and prepared foods to improve their flavor and shelf life. Additional table salt enters the diet when people salt and season their food before eating it.
A low-sodium diet usually limits daily sodium intake to 1,500 mg, which is lower than the recommended daily limit of 2,300 mg and significantly lower than what the average American adult is actually consuming. Very low-sodium diets limit sodium even further. High-sodium foods should be completely eliminated from the diet, and the emphasis should be on whole, natural, unprocessed foods with little to no table salt added.
When following a low-sodium diet, it’s really important to read the nutrition label on any packaged food to gauge the sodium content. Look for foods that contain less than 140 mg of sodium per serving. There are also labels used on products to denote their sodium content, including the following:

12 delicious foods high in vitamin E for skin, hair, and heart health
Vitamin E is crucial for good health: These are great ways to get your daily dose
Bottle of olive oil

Vitamin E is typically associated with skincare, but it does so much beyond nourishing your skin and hair. Vitamin E foods provide the body with powerful antioxidants that aid in reducing inflammation and destroying free radicals to protect your cells from oxidative damage.
Moreover, since vitamin E also plays several roles in supporting the immune system and protecting against diseases such as heart disease and cancer, deficiencies can make you more prone to illnesses, infections, and inflammatory diseases, as well as eyesight impairments and muscle weakness.
Since vitamin E is a fat-soluble nutrient, absorption increases in the presence of dietary fat. Therefore, when eating any food high in vitamin E that isn’t oil or fat itself, it’s best to pair the vitamin E food with another food that contains fat.
Fortunately, there are quite a few foods that contain at least some vitamin E, though the best dietary sources of vitamin E are high in alpha-tocopherol, the most bioactive form of the nutrient. To ensure you have the shiniest, full head of hair, supple and soft skin, and a formidable immune system, keep reading for a list of the foods highest in vitamin E.

How much vitamin E do you need?
The recommended daily value of vitamin E for individuals 14 years of age and older is 15 mg. You can generally get your daily dose of vitamin E through a balanced diet. Taking oral supplements is also available, but you should exercise caution when taking supplements. Excessive vitamin E can create side effects.
Where can you get vitamin E from?
The food groups rich in vitamin E include fats such as canola oil and olive oil. You can get vitamin E from nuts and seeds such as almonds and peanuts. Meat, dairy, leafy greens, and fortified cereals are other great sources of vitamin E.
