The Surprising Dangers of Vitamin B12: What You Need to Know

Vitamin B12 is often celebrated as an essential nutrient for overall health. It helps produce red blood cells and DNA supports the nervous system and plays a crucial role in brain health. However, like most beneficial things, excessive amounts can be dangerous. Yes, you read that right. Vitamin B12, commonly found in meat, fish, dairy products, and fortified cereals, can be harmful if consumed in excessive amounts. How can something beneficial pose a threat to our health? Let’s explore this further. First, it’s important to understand that our body only needs a certain amount of B12, and any excess is typically excreted through urine. However, consuming high amounts of B12 through supplements or fortified foods can lead to an accumulation of the vitamin in our body, causing a condition called hypervitaminosis B12. This condition, known as hypervitaminosis B12, can manifest in various ways, including numbness and tingling in the limbs, muscle weakness, and fatigue. In… Read More

The Warning Signs of Clogged Arteries

By the time many people reach their 20s, blockages that disrupt the flow of blood already exist within their arteries. Responsible for carrying oxygen-rich blood and life-sustaining nutrients from the heart to the rest of the body, healthy arteries are essential for maintaining a healthy body. But when particles of cholesterol, fat, and other cells build up in arteries—thanks mostly to a Western diet loaded with meat, dairy products, and eggs—they create fatty streaks and eventually form plaques that obstruct blood flow. In coronary artery disease—the most common type of cardiovascular disease and leading killer in the United States—these blockages affect the arteries leading to the heart, causing chest pain and often resulting in heart attack. However blockages do not only affect the arteries in the chest. Atherosclerosis, or the thickening of arteries, can strike any artery in the system, leading to different symptoms throughout the body that can serve as early warning signs for… Read More

What causes low LDL cholesterol?

LDL cholesterol is informally known as “bad” cholesterol. Usually, doctors encourage people to lower LDL cholesterol levels. However, when LDL levels fall below 50 milligrams per deciliter (mg/dL) of blood, this may signal a health problem or cause symptoms. Low LDL cholesterol is less common than low HDL cholesterol. Typically, it is secondary to another medical condition, such as: malnourishment from poor nutrition, or from disorders that affect a person’s ability to absorb nutrients hyperthyroidism chronic infections, such as hepatitis C chronic inflammation blood cancers Three genetic disorders may cause low LDL cholesterol: Hypobetalipoproteinemia: A person must inherit two copies of a gene for this condition to develop. It causes the body to metabolize LDL very quickly. Some people with this disorder have no detectable levels of LDL and need treatment. Others have low but detectable LDL levels and do not usually need treatment. Chylomicron retention disease: To develop this condition, a person has to inherit two copies of a certain gene… Read More

Should You Take Dietary Supplements?

When you reach for that bottle of vitamin C or fish oil pills, you might wonder how well they’ll work and if they’re safe. The first thing to ask yourself is whether you need them in the first place. More than half of all Americans take one or more dietary supplements daily or on occasion. Supplements are available without a prescription and usually come in pill, powder, or liquid form. Common supplements include vitamins, minerals, and herbal products, also known as botanicals. People take these supplements to make sure they get enough essential nutrients and to maintain or improve their health. But not everyone needs to take supplements. “It’s possible to get all of the nutrients you need by eating a variety of healthy foods, so you don’t have to take one,” says Carol Haggans, a registered dietitian and consultant to NIH. “But supplements can be useful for filling in gaps in your diet.” Some… Read More
