Best 10 Benefits of Riboflavin

Riboflavin is an alternative name for vitamin B2. Found naturally in foods such as oysters, salmon, avocados, eggs, leafy green vegetables, additional supplementation may not be needed. Always talk to your doctor before beginning new supplements. But first, let’s look at ten benefits of increased riboflavin intake:

1. Treats anemia

Anemia is caused by an insufficient supply of red blood cells. Symptoms include weakness, fatigue, shortness of breath, and more. Luckily, vitamin B2 has been shown to stimulate healthy red blood cell production, thus fighting against anemia.

2. Boosts energy

Energy reserves can be boosted by regular consumption of riboflavin. Metabolism and digestion are also improved by B2 intake.

3. Produces collagen

Got wrinkles? Riboflavin supplements may benefit you. This vitamin is essential in producing and maintaining healthy levels of collagen, which promotes healthy hair and prevents wrinkles from forming by improving skin elasticity.

4. Relieves migraines

Patients with migraines may be suffering from a riboflavin deficiency. Its ability to treat migraines makes it a worthy investment for chronic sufferers.

5. Aids the nervous system

Riboflavin is an extremely versatile vitamin. Its properties are known to relieve several disorders of the nervous system, including numbness, anxiety, and carpal tunnel syndrome. This vitamin has also shown success in alleviating symptoms of epilepsy, multiple sclerosis, and Alzheimer’s.

6. Promotes optical health

The risk of developing eye diseases is greatly reduced by ingesting proper amounts of riboflavin. This vitamin protects the eyes from conditions such as cataracts, glaucoma, and keratoconus.

7. Increases mineral absorption

Vitamin B2 improves the health of the digestive tract, thereby increasing nutrient absorption; additionally, the vitamin itself is able to absorb other minerals such as iron, folic acid, and other B complexes.

8. Promotes fetal development

As with all nutrients, developing fetuses need riboflavin. This vitamin ensures the fetus develops properly and is born at a healthy birth weight.

9. Aids digestion

Riboflavin is essential in maintaining the mucosal lining of the digestive tract, which keeps digestion speedy and efficient.

10. Works as an antioxidant

Arguably the best property of riboflavin is its role as an antioxidant. Adequate riboflavin helps kill harmful free radicals by producing glutathione. Elimination of free radicals is essential in preventing disease.
