Vitamin B8 Functions & Benefits

The roles of Inositol cover a wide range of potential health conditions and afflictions, although scientific evidence sometimes fails to confirm these benefits. It has been observed that a deficiency of this nutrient may affect ATP synthesis and RNA synthesis.

Further research is ongoing and trying to determine the exact extent of this nutrient’s action range and action fields.

There is increased interest in demonstrating the relationship between Vitamin B8 and its stress-relieving effects. Stress is widely defined as including numerous potential sources, from mental-psychological stressors to physical and emotional stress. Conditions such as depression, OCD (obsessive-Compulsive Disorder), phobias, and panic attacks may be the result of stress. It appears that some clinical studies concluded that Inositol might benefit patients with associated symptoms, in the sense of diminishing these effects. One study in particular states clear advantages of the nutrient against conditions that include panic attacks and agoraphobia (the fear of crowds). Patients suffering from anxiety appear to have taken advantage from intake of Inositol, as one study reveals. Also, Inositol was proven by one study to be at least as effective as fluvoxamine in treating symptoms of depression for a significant number of patients, without the unpleasant side effects associated to fluvoxamine.

There are further evidence and many years of clinical settings that testify to certain benefits of Inositol in treating the following disorders: OCD (Obsessive Compulsive Disorder), Bipolar Disorder, moderate and mild depression, senile dementia, panic attacks, and anxiety.

The nutrient has also been touted for benefits against colon cancer, mainly referring to Inositol hexakisphosphate or Phytic acid. The conclusion needs confirmation from large-scale human studies. However, there seems to be a certain connection between high fiber diets (which are rich in Inositol) and decrease colon cancer risk.

Another set of benefits for the substance is linked to its ability to enhance nerve transmission, which further benefits some health conditions such as diabetic neuropathy (a condition experienced by people with diabetes, where severe pain and numbness of the peripheral members is felt) or peripheral injury of any kind.

Other benefits for which the nutrient is undergoing research include promotion of healthy hair and nails, prevention of premature graying, enhancement and ensuring support for the immune system function, and involvement in the metabolism of carbohydrates, fats, and proteins.

Caution

A deficiency in vitamin B8 is uncommon, while toxicity is highly unlikely. However, given that caffeine consumption largely diminishes inositol, caution is advised for heavy coffee drinkers. Inositol is called a conditional vitamin because as the body is exposed to increased levels of stress, the bodily needs for the nutrient increase. Attention should hence be given to providing your body with sufficient amounts of this nutrient in such cases of stress.

A deficiency is usually signaled through such symptoms as skin rashes, increased cholesterol, enhanced homocysteine levels, constipation, vision problems, hair loss, physical fatigue, eczema, tingling hands, drowsiness, confusion, heart and lung disease heightened risk, and other physical and mental symptoms. Excess amounts may also lead, in rare cases, to such symptoms as hallucinations, nausea, vomiting, lethargy, and mental confusion.

There is no recommended daily dose in case of this nutrient as daily requirements have not been established so far. Commonly, supplements contain a 500 mg dose of Inositol, in combination with other nutrients, including other B vitamins. It is estimated that the average American consumes the equivalent of 1 g of Inositol per day.

Adults experiencing extremely stressful periods characterized by episodes of depression or anxiety are particularly recommended to start taking a supplement. However, given that the nature of these conditions (regarding causality and treatment) is highly involved, we do not recommend that you use a dietary supplement without a healthcare provider’s advice in advance. Also, people who regularly exceed 2 cups of coffee per day should also consider increasing the daily intake as depletion of Inositol is done at a much faster pace.

Potential side effects of Inositol are unusual and usually manifest as various gastro-intestinal discomfort symptoms. The nutrient is suitable for children, however, pregnant and breastfeeding women are not advised to supplement their diets with this nutrient.

Sources

Vitamin B8 is abundantly available in a large number of foods. Some of the richest food sources include mushrooms, milk, cheese, whole wheat bread, rice bran, peanuts, peanut butter, walnuts, hazelnuts, oatmeal, egg white, liver (particularly beef liver), yogurt, and almonds, to briefly mention a few of the foods that are rich in Inositol. Starting October 2012, the US Department of Agriculture has not set a daily recommended allowance for this nutrient, nor is Inositol considered an essential nutrient. The nutrient can also be found in some vegetables and cereals in the form of Phytic acid. Lecithin contains large amounts of Inositol, hence the brain function protective benefits of lecithin.

The nutrient enjoys a large variety of benefits but is most frequently featured (alone or in combinations), in a significant number of medicines that aim to alleviate symptoms of stress and anxiety.

    How does one check for levels of B8?
    Can Inositol be taken just depending on symptoms?? If yes for how long and what dosage?

      There is really no sure way to check. Most vitamin blood tests just shows what is circulating in the blood but not what is actually being used by the cells. It is also the condition of your intestines and whether they are absorbing the nutrients they receive. But if it shows up in blood tests as very low or deficient then it is really bad. Symptoms is mostly the way. The most natural way is via your foods look up food rich in b complexes, because each vitamin they mention is actually only one member of a host of the same vitamin – like a family- that’s why the different names each vitamin has (inositol has like 9 with the same beginning name and another word attached to inositol). They just choose the one that science feels is the most active of the whole family. But you see foods have the WHOLE compound working together – the whole family. I guess that’s why nature is so genius? Look up BodyEcology Donna Gates and learn to make fermented veges which will contain not only b vitamins but bacteria that heals your intestines. Natural animal and vegetable oils as well as bone broth which is natural gelatin also heal the intestines, where they once again absord nutrients. Bacteria also convert nutrients and carry them across the intestinal walls into the blood. Oh and beware that most vitamins you see in stores are synthetic -man made – molecules manipulated by man that do not exist in nature. They are NOT the same as they claim. You want to buy the natural whole food based- they’re more expensive but don’t have side effects synthetic ones have . Look up those natural forms. It’s tricky, you have to search through many articles . Or look up vitamin companies that process them as whole foods. Hope this helps.

    I had a surgery called ileoanalanastamosis. I was told that I wouldn’t be able to make b12 or something because I no longer have any large intestine and old have less than 2 feet of small intestine…. is there anything I can do to make sure I get the benefits from my food… I definitely struggle with stress and depression

      Hi Sharlene. Boy, do I have alot to say. I’m going through bad withdrawal symptoms now from ambien. Was on it 4 long time. Started feeling very weak, lethargic, absolutely no energy. I’m crying alot now. Depression. Can’t sleep due to the discontinued use of ambien. I talked with a very knowledgeable man today from GNC about my symptoms, etc. I bought a all natural sleep aid as well as inositol powder. Started taking it today. I have to have high hopes now for myself. Inositol DOES help with depression and anxiety. The powder gets into our bodies faster than the tablets. Along with B-6, to calm nerves. I’m pushing myself now, every day to take a walk but not pushing too hard. If you can take natural supplements instead of meds, DO IT!!! Meds just make all of us worse. Dr’s keep then adding more meds to cover up the last problem. We have to treat and heal our body from inside out. And try keep positive. We will SEE the results!!
