23 Vitamin B7 Foods for a Balanced Diet

Vitamin B7 Foods

Vitamin B7, also known as biotin, is one of eight B-complex vitamins responsible for creating energy in the body. Since our body cannot synthesize this vitamin and store it, it is necessary to include vitamin B7 foods in our daily diet.

Here you will find out why this vitamin is crucial for your health and which foods are rich in biotin.

What Is Vitamin B7?

Biotin, or vitamin B7, is also known as coenzyme R, vitamin B8, and vitamin H. It is a coenzyme that has a vital role in the metabolism of glucose, fatty acids, and amino acids. Coenzymes are compounds that help enzymes trigger or speed up biological reactions. Therefore, many systems in our body depend on this vitamin.

Vitamin B7 Benefits

Vitamin B7 is involved in energy metabolism. Like other vitamins from the B-complex family, it helps the body convert food to usable energy.

As for biotin and pregnancy, it’s essential to know that this vitamin takes part in fetal development. That is why pregnant women need to keep their biotin levels in check to promote the baby’s health. Overall, biotin is safe during pregnancy. However, high doses of this vitamin can be dangerous for the baby.

Biotin vitamin benefits our nails, skin, and hair as it keeps them strong and healthy. That’s why it is sometimes called vitamin H, where H stands for “Haar” and “Haut,” German words for hair and skin.

Although there is not enough evidence, biotin may contribute to the treatment of people with diabetes. According to some studies, it helps the body use glucose more efficiently, too. This study also showed that biotin could increase insulin secretion.

Biotin Foods

Various foods are good sources of this vitamin. For example, meat, fish, eggs, seeds, and nuts are foods high in biotin.

Note that food processing can reduce the content of this vitamin. For example, avidin, a protein found in raw egg whites, binds to biotin and prevents the body from absorbing it. However, avidin loses this ability when cooked, making the vitamin’s absorption in the gastrointestinal tract possible.

Beef Liver

We start this vitamin B7 foods list with beef liver — one of the richest sources of this vitamin. As little as three ounces of beef liver provide 30.8 mcg of biotin. Not only is this type of meat the best source of biotin, but it is also an excellent source of vitamin B5.

Other types of meat are also excellent sources of biotin. Notably, a three-ounce serving of cooked pork chop contains 3.8 mcg of vitamin B7. Besides being one of the biotin food sources, pork is exceptionally high in thiamine, and it is an excellent source of other B vitamins. What’s more, loin cuts are lower in fat, so they are a healthier option than spareribs and bacon.

Tuna rightfully belongs to vitamin B7 rich foods, as three ounces of canned-in-water tuna contain 0.6 mcg of this nutrient. In addition, this type of fish is packed with niacin and vitamin B12. If you include it in your diet, you will also get a fair amount of selenium and phosphorus.

Recommended Daily Intake

You can find the recommended daily intakes for all the nutrients, including vitamin B7 — biotin — in the Dietary Reference Intakes devised by the Food and Nutrition Board (FNB). Since the FNB didn’t have enough data to define more precise values for biotin, it provided Adequate Intakes (AI) for this vitamin.

Whether you take biotin tablets or you get vitamin B7 only through your diet, here are the AIs for biotin:

  • from birth to 6 months — 5 mcg
  • from 7 to 12 months — 6 mcg
  • from 1 to 3 years — 8 mcg
  • from 4 to 8 years — 12 mcg
  • from 9 to 13 years — 20 mcg
  • from 14 to 18 years — 25 mcg
  • 19+ years — 30 mcg

As you can see, the AIs for vitamin B7 differ depending on age. Also, women should increase their daily intake of biotin during pregnancy to 30 mcg. And during lactation, they need 35 mcg of biotin per day.

Vitamin B7 Deficiency

This vitamin deficiency is uncommon as a healthy eating plan tends to suffice in most cases.

That said, some of the biotin deficiency symptoms are:

  • hair loss
  • brittle nails
  • scaly, red rash around the eyes, nose, and mouth
  • dry eyes
  • conjunctivitis

Other symptoms are related to neurological problems, and they include depression, lethargy, and hallucinations.

As for the vitamin B7 deficiency diseases, we should mention alopecia and developmental delay in children.

Thankfully, we can treat biotin deficiency with supplementation or more vitamin-packed foods in the diet. However, to get adequate treatment, it is imperative to find the cause of low vitamin levels.

Who Should Take Biotin Supplements?

Supplements are often recommended to people who are more likely to have low levels of this vitamin.

Usually, people with biotinidase deficiency are also deficient in biotin — vitamin B7 — since this hereditary disorder prevents the body from processing biotin. If this serious medical condition is not treated, it can cause many complications, including:

  • breathing problems
  • vision or hearing loss
  • weak muscle tone
  • coma or even death

Alcoholics are another group at risk of developing vitamin B7 deficiency symptoms, as alcohol reduces the absorption of vitamin B7.

Also, pregnant and breastfeeding women often have lower concentrations of biotin. Following that, many women are advised to increase their vitamin intake as biotin is crucial for normal fetal development.

Side Effects of Taking Biotin

The FNB didn’t define tolerable upper intake levels for biotin as it hasn’t been found that high doses of biotin have side effects. However, high intakes of biotin may interfere with laboratory tests, which can consequently produce false results. For example, high doses of supplemental biotin affect some tests that measure hormone levels and a test used for diagnosing a heart attack.

Conclusion

Biotin plays a crucial role in the body. Along with other B vitamins, it is responsible for energy production. Another essential vitamin B7 function is promoting normal fetal development.

All things considered, our diet has to be rich in this nutrient. Fortunately, there are many biotin-rich foods, making it easy to cover the recommended daily intake.

Please note that even though high doses of vitamin B7 supplements are not toxic, they can interfere with some laboratory tests. That’s why you should exercise caution. As always, we advise consulting a healthcare provider before taking any dietary supplements.
