Can Vitamin B2 Really Lower Blood Pressure? Zhang's Concerns and the Truth!

Zhang, a 65-year-old man, was diagnosed with hypertension last year and has been taking blood pressure medication to control his condition. However, he is concerned about the long-term use of medication and its potential side effects. He recently came across a video claiming that Vitamin B2 is a magical cure for hypertension, capable of lowering blood pressure. Intrigued, Zhang considered replacing his medication with Vitamin B2. However, his wife immediately reprimanded him, stating that he always jumps to conclusions. Zhang felt wronged. Does Vitamin B2 really lower blood pressure?

I. Vitamin B2 and Blood Pressure: Unveiling the Truth

In recent years, the internet has been buzzing with claims that Vitamin B2 can lower blood pressure, leading many to believe these claims and even discontinuing their existing blood pressure medication. This is a dangerous practice. This claim is a misinterpretation of a study published in the international journal "Hypertension" by researchers at Southern Medical University's Southern Hospital in China.

The study tracked over 12,000 participants, recording their weekly dietary intake and estimating their Vitamin B2 consumption. The results revealed a 26% lower risk of developing hypertension in individuals with higher Vitamin B2 intake. Researchers speculate that Vitamin B2 might facilitate the synthesis of Vitamin B6, which in turn improves insulin receptor sensitivity and protects the vascular endothelium, ultimately aiding in blood pressure control.

However, this does not imply that Vitamin B2 has the same efficacy as blood pressure medication. At best, it plays an auxiliary role in blood pressure regulation and cannot entirely replace prescribed medications. Dr. Lu Linchun, Director of Cardiology at New Mile Hospital in Luoyang, Henan Province, emphasizes that while Vitamin B2 can accelerate fat metabolism, indirectly affecting blood pressure, it does not directly lower blood pressure. Most hypertensive individuals require lifelong medication, and abruptly stopping or reducing medication can lead to excessive blood pressure fluctuations, triggering hypertensive emergencies, severely impacting heart, brain, and kidney functions.

II. The True Role of Vitamin B2: Ameliorating Five Health Issues

Vitamin B2, also known as riboflavin, participates in the oxidation-reduction reactions within human cells, promoting the metabolism of fats, sugars, and proteins. It also plays a vital role in the normal functioning of skin, mucous membranes, and vision. However, Vitamin B2 is easily degraded by light and alkaline solutions, making it difficult to store in large quantities within the body. Consequently, deficiencies are relatively common.

When Vitamin B2 levels are insufficient, the activity of yellow enzymes decreases, leading to metabolic abnormalities and potentially triggering skin, mucosal, and eye-related disorders. Supplementation with appropriate amounts of Vitamin B2 can improve the following health issues:

1. Alleviate Oral Inflammation: Vitamin B2 effectively prevents and eliminates oral inflammation like angular cheilitis, glossitis, and cheilitis.

2. Improve Migraines: Studies have shown a connection between riboflavin, mitochondrial cell function, and migraines. Supplementation with riboflavin can relieve stress and reduce nerve-inflammation-induced migraines.

3. Prevent Anemia: Riboflavin enhances the body's iron absorption, aiding in anemia prevention.

4. Prevent and Manage Cardiovascular Diseases: Research has indicated that high-dose Vitamin B2 supplementation can inhibit platelet aggregation, demonstrating a positive effect in preventing coronary heart disease.

5. Improve Sexual Quality of Life: Vitamin B2 deficiencies can lead to mucosal abnormalities, particularly impacting women, potentially causing vaginal dryness, mucosal congestion/rupture during sexual intercourse, and affecting libido. Supplementation with appropriate amounts of Vitamin B2 can improve sexual quality of life for both partners.

III. Four Warning Signs of Vitamin B2 Deficiency

Individuals with a balanced diet usually don't experience Vitamin B2 deficiencies. However, picky eaters and those with dietary imbalances are more susceptible. Mild deficiencies may not exhibit noticeable symptoms, but severe deficiencies can manifest in the following four areas:

1. Mouth: Pain, swelling, fissures, ulcers on the lips, and tongue swelling.

2. Eyes: Photophobia, excessive tearing, blurred vision, conjunctival congestion, and conjunctivitis.

3. Skin: Seborrheic dermatitis, papules, eczematous balanoposthitis.

4. Scrotum: Erythematous type, papular type, eczematous type balanoposthitis, with the erythematous type being the most common.

IV. Scientific Vitamin B2 Supplementation: Three Key Points to Remember

Vitamin B2 is a water-soluble vitamin, generally considered safe. However, higher doses are typically used for therapeutic purposes, and improper usage can lead to adverse reactions. When supplementing with Vitamin B2, consider the following:

1. Prioritize Dietary Sources: Prioritize dietary sources as the primary method of supplementation. Animal products like organ meats, oysters, poultry, and fish are rich in Vitamin B2. However, individuals with abnormal lipid profiles should moderate their intake. Some plant-based foods like citrus fruits, bananas, carrots, oats, tomatoes, grains, etc., also contain Vitamin B2, but they are not recommended as the primary source of supplementation.

2. Appropriate Supplementation: According to dietary guidelines, the recommended daily intake for men is 1.4-1.8mg, and for women, it's 1.2-1.3mg. Generally, a balanced diet can meet daily requirements. If you are treating Vitamin B2 deficiency, the typical dosage is 5-10mg per dose, 10-30mg per day. However, specific dosages should be determined by medical professionals, and self-medication is not recommended.

3. Adverse Reactions: The most common adverse reactions to supplementation are abdominal pain, diarrhea, nausea, and, in a small number of individuals, rashes and itching due to allergies. During supplementation, urine may turn yellow, but this is usually not concerning and resolves after stopping supplementation.

Vitamin B2 is essential for good health, but it's not a case of "the more, the better." A balanced diet usually eliminates the need for additional Vitamin B2 supplementation.
