Hello, Healthy People, and Welcome Again to my Website where I write about the most complex Health Topics in very simplified language so normal people can understand them properly.

Today I have also taken an underrated as well as the topic which everyone will be curious to know about. And I’m sure by reading the title, you also had a curiosity about this. So if you’re new here then you can also check my other sections on my website and I’m sure you would love to read 🙂

So before I step ahead explaining all of these, Do you have any idea about Vitamin B12 and Hypothyroidism? If not then don’t worry because you will know them here 🙂

What is Vitamin B12?

For those who are curious, vitamin B12 is an important form of Vitamin B that helps with how cells use energy and has a role in your nervous system. Without enough Vitamin B12, you won’t be able to make DNA or red blood cells and will have to take it through supplements or injections to get it into your body. People without enough vitamin B12 can be at risk for anemia.

The general population is recommended to get 2.4 micrograms of Vitamin B12 a day, and vegetarians should get three times that amount (6.8 micrograms per day). Most experts agree that there is no harm in getting more vitamin B12 than you need.

Adding vitamin B12 to the water supply has been suggested as a way to help vegetarians and older people get enough. China has already added Vitamin B12 to its water supply. However, this method of administration isn’t practical for most cases, but it’s an interesting idea for the future.

Vitamin B12 is nice to have in your body, but if you’re living a healthy lifestyle, it shouldn’t be a priority to get the recommended amount into your system every day.

If you directly search it in google about vitamin B12, you will find its synonym which is Cyanocobalamin.

Don’t get confused with Riboflavin as its synonym of Vitamin B not B12.

Lack of Vitamin B12 (Cyanocobalamin)?

Vitamin B12 is a water-soluble vitamin that makes up part of the complex molecule known as methylcobalamin. The body needs B12 to help break down food and synthesize DNA. Vitamin B12 deficiency can cause anemia, fatigue, weakness, cognitive impairment, digestive problems, and neurological symptoms, such as impaired memory and thought disorders.

Research indicates that vitamin B12 deficiency is widespread. A study published in the March 2009 issue of “Clinical Chemistry” found that up to 40 percent of older people had insufficient or deficient levels of Vitamin B12. A study published in the June 2010 issue of “Clinical Nutrition” found that over 70 percent of people aged 60 and older had at least marginal Vitamin B12 deficiency.

Dr. Jessica Volpe, an internist, and dietitian at the University of Maryland Medical Center says “If you have adequate amounts of it in your diet, you don’t see a deficiency.”

The body turns Vitamin B12 into a substance called methylcobalamin after it is absorbed through the stomach and intestines. Methylcobalamin is then broken down into its active form, a substance known as adenosylcobalamin.

The nutrient is manufactured in the liver, which turns methylmalonic acid into adenosylhomocysteinase. This substance is then broken down and converted to cobalamin. I know this will go over your head but this is just for information purposes.

Vitamin B12 deficiency primarily affects older adults, breastfed infants, and people who follow vegetarian diets that are low in animal protein. Phew, long princess. Isn’t it?

Which Food Has Vitamin B12?

Vitamin B12 is essential for the proper functioning of the brain and nervous system. Vitamin B12 can be found in meat, poultry, fish, eggs, fortified cereals like fortified cereal flakes, or wheat germ. If you know your daily recommended allowances of vitamin B12 in grams a day: two for adults and three for pregnant women; then you would know that a cup of water-packed tuna has 9.8 μg (micrograms), which meets 6% of your daily requirement. Beans, raw chicken breast, cooked beef round tip, and 2 scrambled eggs have a total of 8.8 μg (micrograms), which is equivalent to 5% of the recommended daily intake. An 8-ounce glass of fortified soy milk contains 3.4 μg (micrograms) of vitamin B12, which meets 2% of your daily requirement. An 8-ounce glass of fortified orange juice contains 3.3 μg (micrograms) of vitamin B12, which meets 2% of your daily requirement.

Vitamin B12 is a water-soluble vitamin that can’t be stored in the body and must be consumed daily from food sources.

Whatever the doses that are written here are based on Research so if you feel like taking Vitamin B12, consider going to Doctors’ First.

Now, you must have got at least an Idea about What is VItamin B12 and How it is useful for the Body and its sources. But we are not on our main point yet as there is another term which is well known and complex so I’m going to explain it here first so you can have a better idea about it.

What is Hypothyroidism?

Before we jump onto Hypothyroidism, let’s make it clear What is Thyroid.

An underactive thyroid can lead to a variety of issues. It can affect the way your body uses energy, how well it converts food into usable nutrients, how well it regulates your body’s temperature, and even causes a swollen and painful neck. In short: those with hypothyroidism may feel tired, experience weight gain or loss as a result of the imbalance between metabolism and calorie-burning capabilities. However, it’s not only your body that is affected.

The thyroid gland, the butterfly-shaped endocrine gland located at the front of your neck, helps regulate how fast your body grows and uses energy. For millions of years, our bodies have been designed to regulate their functions — and that includes our hormones. Because hypothyroidism can cause a variety of symptoms, many doctors are unsure how to diagnose the condition correctly.

So what exactly is hypothyroidism, anyway?

As we know, the thyroid gland is one of the most important endocrine glands in humans. It plays a crucial role in regulating our body metabolism, and most importantly, it affects the growth and health of our brain. This is why hypothyroidism can be dangerous. Those who suffer from this disorder can experience problems with memory, judgment, rational thinking skills, restlessness, and depression among other symptoms.

For the thyroid to produce the right amount of hormones, it requires iodine and selenium. The thyroid also requires selenium to produce enzymes that are vital for thyroid hormone synthesis. Although iodine is abundant in many foods, the western diet is deficient in selenium. 

It is a common thing that some people have problems with the absorption of both iodine and selenium. If this happens regularly and there are no other underlying illnesses present, it is called an autoimmune disease. A study showed that the body can absorb sufficient amounts of selenium if the levels of iodine are normal, but there is a problem with the absorption of selenium in people who have low iodine levels. This is due to an autoimmune disease.

It has been estimated that approximately two percent of all people are affected by Hashimoto’s disease: an autoimmune disease that affects the thyroid gland. People with this disorder cannot properly absorb T3 and T4, and as a result, they produce only small amounts of thyroid hormones. These are the hormones that are responsible for regulating metabolism and, therefore, this can result in several problems including but not limited to mental disorders.

The thyroid gland plays an important role in regulating your body’s metabolism. Without enough thyroid hormone produced by the gland, you may experience a variety of symptoms including fatigue, poor concentration, cold hands and feet, muscle weakness, depression, dry skin, acne, memory loss, and weight gain or loss. Thyroid hormone is also an essential part of the body’s ability to regulate temperature. Without enough of it, you may find yourself suffering from hypothermia or hyperthermia.

The thyroid has an important function in balancing all of the hormones that affect your body. One of the most significant roles in regulating your metabolism, or how fast your body burns calories and converts nutrients into energy.

Your thyroid produces three types of hormones: thyroxine, triiodothyronine, and calcitonin. Thyroxine and triiodothyronine help regulate your basal metabolic rate. Your basal metabolic rate refers to the number of calories needed to keep the body functioning.

How to keep Thyroid Hormones Level Sufficient?

As the body needs thyroid hormone, it’s our job to maintain its level all the time to save yourself from Hypothyroidism.

Before we know How to maintain Thyroid Hormone Levels, you need to know from where they are created or synthesized right?

See, the main ingredient to create Thyroid Hormone is Iodine. And I’m not saying that you should consume Iodine directly but there are other ways to consume it and give iodine to the thyroid gland.

The thing is that, if you want to provide Iodine then the best source would be Salt with Iodine. You can find a company in your town which produces salt-containing enough iodine that is necessary for your Thyroid Gland. 

You can also consume salted nuts but the key thing is Salt should be with iodine.

Not just Iodine but Selenium is also required for Thyroid Hormone activation. You can get Selenium from Brazil Nuts, Chicken, Fish, etc.

Hypothyroidism and Vitamin B12

See as I mentioned earlier that How Much Vitamin B12 is important but Do you know that almost 50% of people who have Hypothyroidism have Vitamin B12 deficiency too. Strange, isn’t it? But you know why see I mentioned Anemia in Vitamin B12 Deficiency as if a person does not have enough amount of Vitamin B12, he will be suffering from anemia. That’s the key because Anemia and Vitamin B12 are connected indirectly. Again surprised? Don’t worry it’s just these medical terms that seem to be harder but they will be easier for you to understand because I’m here.

So, Anemia is nothing but the condition where we don’t have enough Healthy RBCs ( Red Blood Cells ) and hence there is also a lack of Oxygen carried to the Body. And Pernicious Anemia decreased absorption of Vitamin B12. 

Now, Whatever I will be showing here will be the result of an experiment done by a group of scientists on Hyporhytoid Patients. Almost more than 90 Women and less than 25 men were taken under this study. Scientists found out that almost 45% of patients with Hypothyroidism were also having Vitamin B12 deficiency. 

See the % is less than even half so there is no thumb rule that a patient with Hypothyroidism is also Vitamin B12 deficient. Also in that study, it was concluded that not all patients with Vitamin B12 deficiency had Anemia. However, Vitamin B12 administration was found effective in Hypothyroid Patients to some extent. 

So, I can conclude that if you say if there is a 100% relationship between Hypothyroidism and Vitamin B12 deficiency then I would answer it with that It depends on Patient to Patient. Yes, Vitamin B12 supplements indeed helped Hypothyroidism patients to get improvement in their Health but this doesn’t mean if you feel like symptoms I mentioned and you went to a medical store and bought yourself some injections of VItamin B12. Please keep in mind that this is Doctor and Pharmacist’s Job to determine the doses so if you still have any confusion then you must meet the family doctor for sure.
