What Does The Medical Research Say About Vitamins And Mineral Supplements For Tinnitus
If youre wondering what the medical literature reveals, I recommend the article The Allure of the Magic Pill: What Science Says About Dietary Supplements to Help Tinnitus by Dr. Cláudia Barros Coelho, MD, PhD, a Brazilian otolaryngologist who has specialized in the management of tinnitus and hyperacusis for over 20 years.
If youre determined to try then you should have blood work done to determine if you have vitamin and mineral deficiencies, and discuss with your physician which supplements would be appropriate based on those results, she advises.
Her article summarizes the evidence for gingko biloba, zinc, vitamin B12, melatonin, flavonoids, and magnesium. While nothing stood out as very effective, in some cases a diet lacking in certain vitamins and minerals can lead to tinnitus, so its important to see your doctor first, she said.
If youre determined to try them then you should have blood work done to determine if you have vitamin and mineral deficiencies, and discuss with your physician which supplements would be appropriate based on those results, she advises.

But we also dont need to wait for the next big breakthrough, because valid treatments already existjust not in a bottle of supplements or ear drops.

What Is Folic Acid
Folic acid , also known as vitamin B9, folacin, or pteroyl-L-glutamic acid, is one of the B vitamin complexes. Folic acid becomes bioactive for the body when it is metabolized by the liver, which converts it into dihydrofolic acid.
The body is not able to create folate, or vitamin B9, on its own it needs to receive folate via the diet, or folic acid via supplementation. Folate is found naturally in many foods:
- all cruciferous vegetables
- citrus fruits including oranges, lemons, grapefruits
It is rare that a serious deficiency is found in the body. However, people often choose to take this vitamin as a supplement because the natural vitamin B9 that occurs in food can be damaged by a high temperature when food is cooked.
Many people take vitamin B9 supplements to boost the growth and condition of their hair, skin, and nails because the vitamin is required for the creation and repair of DNA, the coding of proteins, and the synthesis of new cells and tissues.
Vitamin B9 deficiency can compromise the health of the hair and skin and cause a number of conditions such as anemia, chronic diarrhea, or more serious cognitive and neurological issues and birth defects when a serious deficiency is maintained long term.

B12 is stored mainly in the Liver with a total body store of 2-5mgs in an adult. B12 is excreted per day) in the bile and reabsorbed.

What Vitamin B12 Cant Do
The Internet is full of articles lauding the use of vitamin B12 to prevent Alzheimers disease, heart disease, and other chronic conditions or reverse infertility, fatigue, eczema, and a long list of other health problems. Most are based on poor or faulty evidence.
Take Alzheimers disease as an example. Although there is a relationship between low vitamin B12 levels and cognitive decline, clinical studiesincluding those involving people with Alzheimers diseasehave not shown improvement in cognitive function, even doses of the vitamin as high as 1000 micrograms.
For now, its best to get enough vitamin B12 to prevent a deficiency, and not look to it as a remedy for what ails you.

Recommended Doses Of Vitamin D
Its recommended that you get at least 600 IU or 15 micrograms of vitamin D a day starting at the age of 1. Babies younger than 1 should receive 400 IU of vitamin D. For people over the age of 70, the suggested intake jumps to 800 IU . If youre concerned about your vitamin D intake, ask your doctor about checking your vitamin D levels. When you get the recommended daily amount of vitamin D, youre able to maintain hair growth, bone health, and normal calcium breakdown.
Research shows that a lack of vitamin D in your body can lead to hair loss. One role vitamin D plays is stimulating new and old hair follicles. When there isnt enough vitamin D in your system, new hair growth can be stunted.
Vitamin D deficiency has been linked to alopecia, the autoimmune condition that causes bald patches on the scalp and other areas of the body. Both men and women can experience alopecia. Another study found that women 18 to 45 years old who experienced alopecia or other types of hair loss had low levels of vitamin D.
Reasons for insufficient vitamin D levels include spending more time indoors, wearing a lot of sunscreen, and not eating foods packed with the nutrient.

How Vitamin B12 Is Related To Hair Growth
Even though the protein keratin, which is the main ingredient in your hair, is dead, hair follicles beneath it are quite alive and need nutrition. The hair follicles need oxygen and nutrients to grow which can only be supplied through blood.
A new hair strand grows when your hair cells divide and multiply. Your hair bulb base consists of blood vessels that connect your hair follicles to your body’s blood supply.
Vitamin b12 assists the production of oxygen-rich red blood cells, which carry oxygen to your hair follicles. It is a biological process to produce new hair cells and promote hair growth.
The vitamin plays a significant role in cell division, cellular metabolism, and DNA replication. Whenever a hair cell reproduces, it makes a copy of its DNA. Thus, hair growth is dependent on the synthesis of DNA and absorption of vitamin b12.

How Does Vitamin B12 Affect Hair Growth
When the cells in the hair follicle divide and multiply, you have the growth of a new hair strand. You would be surprised to know that the hair bulb has the fastest-growing cells in the human body. The base of the hair bulb consists of the blood vessels which connect the hair follicle to the bodys blood supply. They supply oxygen and other essential nutrients to the hair follicle.
Vitamin B12 aids the production of red blood cells. The red blood cells are oxygen-rich and play a key role in carrying the oxygen from the lungs to all the parts of the body. Thus, appropriate vitamin B12 levels facilitate a healthy scalp and stimulates hair growth. Having appropriate vitamin B12 levels is instrumental to hair growth. Vitamin B12 also plays a key role in cellular metabolism, cell division, and DNA replication. The Vitamin B12 deficiency can hinder the synthesis of DNA during cell division at the hair follicle and result in vitamin B12 deficiency hair loss.

Why Lack Of B12 Causes Hair Loss And Greying
Our hair grows each day as the hair cells divide and multiply, pushing the hair out and above the skin surface. You can imagine hair cells stacking up like Lego blocks, the only thing is that its building from upside down.
Compared to other cells of the body, hair follicle cells are one of the fastest growing cells. And they are dependent on a regular supply of nutrients. One of them is B12, as it is required for DNA synthesis. Without it, the instructions for building the cells are incomplete, and cells are unable to divide and grow.
Therefore, when the levels of B12 go down, the hair cells cant multiply properly. This may cause the hair growth to slow down, or in a few cases, even to stop completely. Also, a lack of B12 affects overall health, and if you are unwell, your hair will not thrive. It will suffer too.
The good news is that when Vitamin B 12 levels are restored, hair cells may be able to grow and replicate properly. And your lost hair could grow back in a few months.
How B12 Deficiency Turns Hair Grey
Our body is all interlinked one compound goes down, the other goes up. So a balance is imperative. When the B12 levels go down, the levels of homocysteine** go up.
Elevated homocysteine is not good for our body as well as our hair. This is because a high level of homocysteine is known to generate hydrogen peroxide which literally bleaches and the hair from the inside out, turning your hair grey.
