Too Many Vitamins Can Be Bad For You

When too much of good things can be lethal!

Vitamins are organic compounds needed in small quantities to sustain life, Medical News Today reported. We normally get the necessary amount from our daily diet, but sometimes, due to dietary restraints, individuals will develop vitamin deficiencies. However, Marissa Puleo, a registered diectian, told Medical Daily that one needs to be careful with vitamin intake.

“Taking too many vitamins and supplements does have negative consequences,” Puleo said. Although many water soluable vitamins are excreted when too much is taken, others remain in the body. “These vitamins can reach toxic levels and cause adverse side effects.”

 

Iron
Anemia is a condition when one doesn’t have enough healthy red blood cells to carry adequate oxygen to your tissues. It’s more common among women and can cause symptoms such as fatigue and feeling weak. Do not self-diagnose your anemia and especially don’t self-treat it. Unnecessary iron can accumulate in the body and even rise to toxic levels.

Probably one the most widely known and one of the most dangerous vitamin overdoses, particularly for children, is an iron overdose.  While iron is necessary for red blood cells and the prevention of anemia, an iron overdose can lead to death, and is actually the leading cause of fatal poisoning in children younger than 5.

As reported by Livestrong, a one-time overdose of iron can kill you. The limit for iron intake is put at around 20mg of elemental iron per kilogram of body weight. Any more than this and a person may experience abdominal pain, persistent vomiting, rapid breathing, and coma!

Vitamin C
Vitamin C one of the most popular and widely recognized of all vitamins. Deficiencies of vitamin C can cause tooth lose, acne, fatigue, and even death. Taking vitamin C to help fight off a cold is also recommended by doctors. Still, despite all this there is still such a thing as having too much of it. Too much vitamin C or zinc could cause nausea, diarrhea, and stomach cramps. Too much selenium could lead to hair loss, gastrointestinal upset, fatigue, and mild nerve damage.

Vitamin A
Known for promoting good vision and helps in forming and maintaining healthy skin, teeth, skeletal and soft tissue, and the mucous membrane. Medline Plus reports that individuals who do not get enough vitamin A are more likely to get infectious disease and vision problems.

A high dose of vitamin A can cause the following side effects: nausea, vomiting, diarrhea, loss of appetite, tiredness, headaches, dizziness, blurred vision, poor muscle coordination, itchiness and scaling of the skin, bone pain, hair loss, irregular menstruation in women, osteoporosis, and temporary or permanent liver damage.

Vitamin B
B vitamins, a group of 8 distinct vitamins, each responsible for aiding various functions in the body.  The functions of the vitamin B group range from supporting the rate of metabolism, promotion of healthy skin and hair, as well as memory support.  Vitamin B6 overdose can lead to nerve toxicity, while B3 can lead to nausea, jaundice, and liver toxicity.  Too much folic acid, too, can mask the symptoms of a B12 deficiency.  So how much is too much?  Typically, 300 mg of B6 is scary territory, while 2000 mg of B3 is risky.  For folate, the Institute of Medicine recommends adult men and women not consume more than 1000 mg per day. In order to avoid a vitamin B overdose, make sure you consult your healthcare professional.

Vitamin D
Vitamin D responsible for the regulation of calcium and phosphorus in the bones. Coupled with a lack of calcium intake and physical activity, your bones would likely become soft and weak over time, increasing the risk of osteoporosis, discomfort in the bones, and even a greater risk of broken bones!

Even vitamin D overdose is extremely rare, there is such a thing as too much. Too much vitamin D can cause permanent damage to your kidneys and heart. Vitamin D overdose symptoms although perhaps temporarycould cause nausea, vomiting, alternating constipation and diarrhea. Sometimes vitamin D overdose can even result in dangerous heart rhythm abnormalities. In addition, a vitamin D overdose in pregnancy has been shown to increase the potential of mental retardation in babies. Though the recommended daily requirement of vitamin D is around 1,000 IU, many doctors believe this is too low and regularly prescribe more to those who are vitamin D deficient.

The best way to determine the appropriate amount of vitamin D for you and avoid overdose is to avoid so-called mega-dosing, consult your own healthcare professional, and have your levels tested.
