Does Taking Too Much Vitamin B Make Your Hair Fall Out

Does Vitamin D3 Deficiency Cause Hair Loss?

Vitamin B is not a single vitamin, but rather a group of vitamins consisting of eight members: Thiamine, riboflavin, niacin, pantothenic acid, B-6, biotin, B-12 and folate. B vitamins are water soluble, which means if you get too much the excess is excreted in your urine and unlikely to cause health problems. However, a deficiency in any of the B vitamins can cause troubling symptoms, including hair loss. If you think you are deficient in the B vitamins, speak to your doctor about boosting your blood levels.

What Is Vitamin D Deficiency

If you are not getting enough Vitamin D in the body, either due to a lack of sunlight or due to a poor diet, you develop a vitamin D deficiency. Your skin is capable of producing Vitamin D when exposed to sunlight, however, if you live in a cold country with limited access to the sun or have a sedentary indoor lifestyle it may cause low vitamin D levels. Fair-skinned individuals can convert more sunshine into vitamin D, those with more melanin in the skin are less efficient in producing vitamin D.

How Much Is Too Much

For an adult over 19 years of age, 4300 International Units of Vitamin A per day is considered sufficient for the proper functioning of the organism. These are normally ensured by a balanced diet, with little need for supplementation in a healthy person.

In order to overdose on Vitamin A, you would have to consume around double your recommended daily intake. According to government guidelines, the upper threshold to which excess intake of Vitamin A is tolerated by your body is 10,000 IU. Exceeding this threshold over a prolonged period of time will lead to overdosing and Vitamin A Toxicity, with severe effects for your health.

If you are planning on taking any Vitamin A supplements, it is advised that you speak to your doctor first. It is relatively difficult to overdose on Vitamin A purely by eating the foods in which it is found.

Vitamin A can be ingested under two forms: retinol and beta-carotene .

However, as the same study cited above points out, Vitamin A toxicity does not occur from the ingestion of beta-carotene, regardless of the dosage. It is only reported when overdosing on retinol. This can only happen through supplementation, as the doses normally ingested through diet even in large portions, are far too small to do real harm.

What Does Vitamin D Have To Do With Hair Loss

Lack of vitamin D may not be the reason for all types of hair loss, but it may play an important role in the development of alopecia areata and pattern baldness.

Vitamin D works by binding to vitamin D receptors found in all kinds of cells in your body, such as immune cells, kidney cells, and hair follicles. One important function of vitamin D is to help regulate cell cycles, which is particularly important when it comes to hair growth. In patients with alopecia areata, for example, research seems to show that hair follicle cycling is disrupted due to low levels of vitamin D .

In one study, researchers found that patients with alopecia areata were more likely to be vitamin D deficient .

Less research exists linking vitamin D to pattern hair loss, however, recent research found that lower vitamin D levels correlated with more severe cases of this type of hair loss . Not just thattheres even evidence that treatment with vitamin D may help restore hair growth. More on that below.

âThere is a link between vitamin D deficiency and alopecia, and it is often one of the common causes of thinning hair or hair loss in men or women,â Arielle Levitan, MD, an internal medicine physician in Chicago, tells WebMD Connect to Care.

A 2017 review in the International Journal of Molecular Sciences found that low vitamin D levels have been linked to:

Vitamin D Benefits And Warnings

Although the research is still hazy, some people will benefit from taking vitamin D supplements, along with sufficient calcium intake, to promote their bone health. But they don’t require large amounts of vitamin D to get the benefit. “More is not necessarily better. In fact, more can be worse,” says Dr. Manson. For example, a 2010 study published in JAMA showed that intake of very high doses of vitamin D in older women was associated with more falls and fractures.

In addition, taking a supplement that contains too much vitamin D can be toxic in rare cases. It can lead to hypercalcemia, a condition in which too much calcium builds up in the blood, potentially forming deposits in the arteries or soft tissues. It may also predispose women to painful kidney stones.

If you’re taking vitamin D supplements, the take-home message is moderation. Taking too much can limit the benefits of the sunshine vitamin.

Vitamin D supplements could help if a vitamin D deficiency is contributing to your hair loss. Vitamin D can come in a pill, or it can be applied to the skin through creams like calcipotriol, a psoriasis drug that has shown promise in treating hair loss.

âSupplementing vitamin D can often be helpful since most people are deficientâalong with other key nutrients, typically iron, vitamin C, and biotinâin restoring hair loss. It certainly helps thicken existing hair,â Levitan says. âThe amount to take varies on the individual’s needs, based on who they are, sun exposure, and other medical problems.â

Getting 10 to 30 minutes of sun exposure is a way to get vitamin D, but this could raise skin cancer risks. The amount of sun needed to form Vitamin D will vary depending on your skin type, how much skin is exposed, and where you live. According to Levitan, getting between 800 and 2,000 IUâor 20 to 50 microgramsâof vitamin D daily is usually enough, and âtoo much can cause toxicity.â Some people require 5,000 IU daily to maintain optimum blood levels and Vitamin D should be taken in the morning with Magnesium for maximum bioavailability.

What Is Vitamin D

According to the National Institutes of Health, Vitamin D is an essential, fat-soluble vitamin that plays a role in numerous biological processes within your body.

Unlike most vitamins, vitamin D isnt commonly found in foods. While some foods, such as milk, soy and certain types of fish, contain vitamin D, most vitamin D is produced endogenously when UV rays from sunlight come into contact with your skin.

In its natural form, vitamin D is biologically inert. To use vitamin D, your body needs to convert it into a usable form using the liver and kidneys.

This complex, multi-step process is referred to as hydroxylation, and allows your body to use vitamin D for a variety of important processes.

Vitamin D plays a role in countless biological processes within your body. Its responsible for:

  • Promoting calcium absorption

  • Ensuring healthy bone growth and remodeling

  • Modulating cell growth

  • Reducing inflammation

  • Maintaining a healthy immune system

Vitamin D also plays a key role in preventing certain diseases. People with low levels of vitamin D have an increased risk of developing rickets and osteomalacia two diseases that can affect the health and integrity of your bones.

Low levels of vitamin D are also linked to certain forms of hair loss a topic weve discussed in more detail below.

What Happens If You Have Too Much Vitamin D

Although its important to take in a certain minimum amount of vitamin D for optimal health, its definitely possible to get too much vitamin D.

Your body limits the amount of vitamin D that it will produce due to sun exposure. This means that theres no real risk of you overdosing on vitamin D if you spend too much time outside on a sunny day, although there are obviously other risks involved in excessive sun exposure.

However, overusing vitamin D supplements can cause something called vitamin D toxicity a potentially harmful condition that can cause nausea, vomiting, constipation, weakness, weight loss, reduced appetite, heart rhythm problems and even damage to your kidneys.

To avoid vitamin D toxicity, only use vitamin D supplements as recommended by your healthcare provider or other healthcare professional.

However, taking too much Vitamin D can produce a lot of calcium in your bones and can even damage the kidneys and heart.

If you have any underlying medical conditions which may impact your ability to consume supplements you must ensure you take advice from your doctor before starting any kind of supplementation regimen.
