Hair Loss Causes: Can Too Much Vitamin A Cause Balding

One of the most common causes of hair loss is irregular nutrition and vitamin deficiency. Especially deficiency of vitamins and minerals such as B12, vitamin D, folic acid, biotin, zinc, and iron can lead to temporary shedding. Vitamin and mineral analysis should be done to detect the cause of hair loss.

Zinc, iron, magnesium, vitamin A, vitamin C, calcium, and biotin are essential for hair health. It is sufficient to wash the hair twice a week too. Vitamin A is a crucial vitamin that takes part in many functions, such as immune system and bone development. It is abundant in foods such as meat, liver, fish, milk, yoghurt, eggs, cheese, and butter. Its deficiency may lead to hair loss.

Vitamin A is effective in maintaining skin health. However, excess of this vitamin has a toxic effect on the liver. It also causes undesirable effects, such as headaches, depression, psychological disorders, abdominal pain, fatty liver, and yes, sometimes hair loss and baldness. Therefore, people who want to use vitamin A supplements should consult their physicians first. The daily dose of vitamin A should not exceed 1000 mcg.

Zinc Deficiency Treatments And Considerations

In one study of 312 people with AA, TE, and male and female pattern hair loss, all were shown to have lower zinc concentrations compared to 30 people with no hair loss. Those with AA and TE had the lowest levels of zinc. Another study showed those with AA and low zinc levels benefitted from zinc supplementation .

Researchers warn that using supplements when zinc levels are already normal can be dangerous and do not show a benefit. Zinc toxicity can cause pain, vomiting, and diarrhea, and long-term over-supplementation can lead to adverse interactions with iron and reduced immune function .

A few things to consider if you think you may be suffering from hair loss due to a zinc deficiency include :

  • Zinc deficiencies are uncommon in North America, but they can occur with conditions that make it harder to absorb zinc, such as inflammatory bowel disease, gastric bypass surgery, pregnancy, and alcoholism.
  • Vegetarians have an increased risk of deficiency because zinc levels are lower in vegetables than in meat.
  • Foods high in zinc include oysters, red meat, poultry are the highest other good sources: seafood, nuts, beans, whole grains, fortified breakfast cereals, and dairy products.

Taking Too Much Vitamin C Can Cause Digestive Issues

Too much vitamin A can cause hair loss, so make sure youre getting ...

Overdoing water-soluble vitamins is less dangerous than overdoing fat-soluble ones, but overdosing on vitamin C, for example, while rare, can still cause nausea, diarrhea, and stomach cramps, according to Lambert.

Vitamin C has many benefits, including keeping the immune system healthy, but most people dont need a supplement if theyre eating a decent amount of fruit and vegetables, she said.

An orange or a cup of strawberries, chopped red pepper, or broccoli provides the recommended daily 65-90 milligrams of vitamin C, according to the Mayo Clinic.

A post shared by RHIANNON LAMBERT BSc MSc RNutr

Lambert and other experts recommend a food first approach to nutrition, because its easier for your body to absorb vitamins from food, rather than in supplement form.

Some capsules dont disintegrate quickly enough for the body to use the nutrients, especially if the coating is shiny or waxy, she said.

Vitamin Deficiency And Hair Loss In Women Over 40

There are many factors that can contribute to hair loss in women over 40. For example, hair loss can be triggered by symptoms related to age, genetics, and hormones. In particular, menopause can cause hormones that affect hair growth as well as the overall look and vitality of hair. This is all a very normal part of aging.

Most causes of hair loss, however, are within our control. Vitamin deficiency is also a major cause of hair loss in women over 40. Focusing on taking care of our bodies through proper diet, nutrition, and vitamin intake can help foster stronger, healthier hair. When we are lacking certain nutrients, our bodies respond, sometimes causing effects such as hair loss, hair thinning, and breakage.

Although aging is a natural and beautiful part of life, many people relate strong, thick looking hair to beauty and health. To achieve this at any age we have to pay attention to our vitamin intake and our overall health. Just like our bones, skin, eyes, and heart, our hair is reliant on what we put into and on our bodies. That means that the best haircare products for hair loss are those that contain the right vitamins and nutrients that our bodies need in order to thrive.

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. This can have 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 in two forms. Retinol is naturally found in liver and dairy, while beta-carotene is naturally found in vegetables such as carrots.

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.

It also helps us regenerate bodily tissues like our skin and hair.

There are two different types of vitamin A preformed , which is found in animal products like meat, poultry, eggs, and fish, and provitamin A, which comes from fruits and vegetables. The recommended daily allowance for vitamin A is 700 micrograms for adult women, which most people can get from food alone. However, because of its proposed benefits for aging, many older folks resort to taking vitamin A supplements but health experts say this may be unsafe.

Doesnt Vitamin A Stimulate Hair Growth

Vitamin A is essential for healthy hair. It repairs it and helps to keep the scalp moist. Many hair loss treatments contain Vitamin A as it is thought to stimulate hair growth.

Moreover, beta-carotene, one of the two forms of Vitamin A, has been found by research to have beneficial anti-inflammatory properties which are particularly beneficial to patients with Alopecia Areata .

Vitamin A is a fat-soluble vitamin, which means its stores can build up in the liver where it is stored. While vitamin A is vital for your overall health, over time, excessive intake can actually cause vitamin A toxicity. This may lead to vertigo, headaches, and nausea, as well as skin peeling and weight loss .

Too much vitamin A takes its toll on your hair, too. If you take too many supplements of the Retinol kind over a prolonged period of time, the hair follicles will go into overdrive. This means that your hair will be reaching the end of the growth phase too quickly and falling out. If your body is unable to make new hair quickly to replace it, you can end up experiencing hair thinning and in severe cases, baldness.

Types Of Vitamin A Deficiency

There are two types of Vitamin A deficiency: primary and secondary.

In primary deficiency, you do not get enough dietary vitamin A from what you eat â different animal and plant sources such as liver, dark leafy vegetables or fruits. This deficiency can be treated either by increasing the dietary intake of vitamin A or taking supplements.

In case of secondary deficiency, different factors such as alcoholism, smoking or zinc deficiency affect the effective absorption of vitamin A from your intestines. This leads to an increased deficiency of vitamin A in the body. This type of deficiency can only be treated by fixing whatever is contributing to decreased absorption of vitamin A.

Symptoms of vitamin A deficiency in the body include impaired vision, dry eyes, conjunctivitis and a weakened immune system.
