Vitamins are essential to the well-being of all humans. These organic compounds help keep our bodies running in tip-top shape when consumed as part of a healthy, active lifestyle.

Most people know of vitamin deficiency, the long-term shortage of an essential vitamin or group of vitamins. 

This insufficiency comes from poor vitamin intake, also known as primary deficiency, or a natural inability to properly process vitamins, aka secondary deficiency, due to underlying illness or disease. Depending on the vitamin in question, deficiency can lead to a whole range of medical problems, including fatigue, muscle weakness, hair loss, excessive bleeding, and more.

Unfortunately, far fewer people realize it is also possible to consume too many vitamins, unintentionally exposing their bodies to various unpleasant symptoms and possible illnesses/diseases.

On that note, let’s explore the risks of excessive vitamin consumption to help you better understand the importance of proper intake levels:

The Dangers of Vitamin Overconsumption

Regarding vitamin supplementation, it is crucial to understand that even healthy organic compounds are most useful in moderation.

Your body needs the 13 essential vitamins - vitamins A, C, D, E, K, and the B vitamins (niacin, riboflavin, thiamine, pantothenic acid, biotin, B6, B12, and folate) - to perform optimally. Still, excessive consumption of any of these can be dangerous.

Regularly taking dangerously high doses of vitamins, particularly in conjunction with one another, can negatively influence your body’s ability to regulate its essential functions.

While the effects of excess consumption depend on the form, quality, quantity, etc. of the vitamin(s) taken, possible adverse outcomes include:

  • Easy Bruising/Excessive Bleeding (excessive niacin)
  • Frequent Urination (excessive Vitamin D)
  • Skin Flushing (excessive Vitamin C)
  • Joint and Bone Pain (excessive Vitamin A)
  • Blurred Vision (excessive Vitamin E)
  • Kidney Problems (excessive biotin)
  • And More
  • Can You Overdose on Vitamins?

    Put bluntly, yes. The colloquial term for this is “vitamin toxicity,” and the medical term is “hypervitaminosis.”

    Most people only associate overdoses with recreational drug use or excessive prescription medication intake, but it is possible to overdose on vitamins.

    While it is highly unlikely to enter hypervitaminosis through consuming vitamins naturally found in your food, manufactured supplements are another matter.

    How do Vitamin Overdoses Happen?

    Many people take popular vitamin supplements, like multivitamins, vitamin D, B complex vitamins, etc., in highly concentrated doses. They believe these “super supplements” offer them a leg up on naturally-occurring alternatives or standard supplements.

    When these boosted supplements come from reputable, medically-inclined manufacturers, the suggested dosage of the vitamin will likely be safe, and any risk will come from trying to push the limits. Overdoses through this kind of supplementation often require consistent abuse over an extended period.

    However, when these souped-up vitamins come from illegitimate manufacturers suggesting vitamin consumption in large amounts clearly above the RDA, the remote possibility of a vitamin overdose becomes far more likely. This is particularly true if the patient is abusing multiple vitamins at once.

    Pro Tip: Be exceptionally mindful when supplementing with folic acid and/or vitamin D, as these are two of the vitamins that most often lead to hypervitaminosis.

    How to Identify and Treat a Vitamin Overdose

    While it depends on the vitamin(s) in question, here are some of the general symptoms to watch out for if you believe you or someone you know may be overdosing on vitamins:

  • Severe Nausea or Diarrhea
  • Loss of Sensation (due to Nerve Damage)
  • Highly Irregular Heartbeat
  • Convulsions
  • Debilitating Migraines
  • Dramatic Mood Swings

  • If you experience any of these symptoms, stop your vitamin consumption and closely monitor your condition. You may need to seek immediate medical care. 

    How to Take the Right Amount of Vitamins for You

    To take vitamins properly, you must always consume the recommended daily amount(s) for you and speak with your doctor about any supplementation regime you plan to undertake.

    Understand RDA’s

    Your Recommended Daily Amount (RDA) for a specific vitamin can depend on many factors, including your sex, age, height, weight, diet, pre-existing medical conditions, and lifestyle.

    For example, the RDA of Vitamin D is 400 IU for children <12 months, 600 IU for adults 1-70, and 800 IU for adults over 70. In this case, age is a significant influencing factor on your recommended daily consumption.

    Regardless of the vitamin you supplement with, it’s always essential to research using reputable medical sources and find the RDA that best suits you and your health needs.

    Communicate with Your Doctor

    In addition to your personal research, it is always a good idea to speak with a medical professional before embarking on any vitamin supplementation program.

    A doctor with access to your complete medical history can best identify the type and quantity of vitamins needed to help you reach your health and wellness goals.
