B vitamins: Folate, along with vitamins B6 and B12, has been shown in numerous studies to help lower homocysteine levels. The active form of folate, L-methylfolate, can achieve plasma folate levels up to 700% higher than synthetic folic acid and therefore may be more effective at lowering homocysteine levels.
Can B vitamins lower homocysteine?
The good news: Homocysteine can be lowered easily and inexpensively with a trio of B vitamins — B6, B12, and folic acid. Problem solved? Not so fast. Lowering homocysteine doesn't mean much unless those reduced levels translate into reduced risk for the problems that elevated levels are thought to cause.
How does homocysteine affect bone resorption?
In vitro studies have shown that slightly elevated concentrations of homocysteine (from 10 mmol L−1) increase osteoclast activity and bone resorption [52,53], leading in turn to an inhibitory effect of homocysteine on bone formation [54].
Can B vitamins help prevent Alzheimer’s?
A further study headed by Professor David Smith found those people with raised homocysteine given B vitamins, compared to placebos, had an eight-fold reduction in shrinkage of the medial temporal lobe, which is the specific area of the brain that shrinks in Alzheimer’s [13].
Are B vitamins modifiable factors associated with bone health?
Abstract. This review will explore the emerging evidence of the supporting role of certain B Vitamins as modifiable factors associated with bone health. Individuals with high levels of homocysteine (hcy) exhibit reduced bone mineral density (BMD), alteration in microarchitecture and increased bone fragility.

Which vitamins reduce homocysteine?
Homocysteine is an amino acid in the blood, and elevated levels have been linked to dementia, heart disease, stroke, and osteoporosis. The good news: Homocysteine can be lowered easily and inexpensively with a trio of B vitamins — B6, B12, and folic acid.
Which B vitamins participate in homocysteine metabolism?
The present review focuses on the B-vitamins, i.e. folate, vitamin B12, vitamin B6 and riboflavin, that are involved in homocysteine metabolism.
Does B12 lower homocysteine levels?
The most important nutrients that help lower homocysteine levels are folate, the vitamins B12, B6 and B2, zinc and trimethylglycine (TMG).
Which three B vitamins are necessary for inhibiting the production of homocysteine?
It is known that serum homocysteine is regulated by Vitamin B12 and folic acid, and supplementation with these vitamins decreases serum homocysteine levels. It is also known that folate, Vitamin B12, Vitamin B6 and riboflavin are involved in the metabolism of an S-containing amino acid, homocysteine.
What is the link between homocysteine the B vitamins folate vitamin B12 and vitamin B6 and heart disease?
Homocysteine is an amino acid. Vitamins B12, B6 and folate break down homocysteine to create other chemicals your body needs. High homocysteine levels may mean you have a vitamin deficiency. Without treatment, elevated homocysteine increases your risks for dementia, heart disease and stroke.
How do you reduce homocysteine levels?
Elevated homocysteine levels can be lowered. We know that folic acid, vitamin B6, and vitamin B12 are all involved in breaking down homocysteine in the blood. Therefore, increasing your intake of folic acid and B vitamins may lower your homocysteine level.
Does folate reduce homocysteine?
Folic acid is the most important dietary determinant of homocysteine; daily supplementation with 0.5 to 5.0 mg typically lowers plasma homocysteine levels by about 25 percent.
Does vitamin D lower homocysteine?
In conclusion, vitamin D3 intervention with a treatment dose of 50 000 IU per week for at least 2 months can help decrease BMI and homocysteine levels, which in turn will help prevent or minimize the risk of CVD among overweight women of reproductive age.
How are folic acid vitamin B12 and homocysteine related?
Folate and vitamin B12 are essential nutrients, whose deficiencies are considerable public health problems worldwide, affecting all age groups. Low levels of these vitamins have been associated with high concentrations of homocysteine (Hcy) and can lead to health complications.
What does vitamin B6 do?
Overview. Vitamin B-6 (pyridoxine) is important for normal brain development and for keeping the nervous system and immune system healthy. Food sources of vitamin B-6 include poultry, fish, potatoes, chickpeas, bananas and fortified cereals.
What does Nat B do to the body?
NAT B is used to treat and prevent vitamin B deficiency and support healthy body function in conditions where the requirement for vitamin B may be higher such as increased emotional stress, chronic alcohol consumption, surgery and recovery from sickness.
What is the role of vitamin B12?
Vitamin B12 is needed to form red blood cells and DNA. It is also a key player in the function and development of brain and nerve cells. Vitamin B12 binds to the protein in the foods we eat. In the stomach, hydrochloric acid and enzymes unbind vitamin B12 into its free form.
Which vitamins regulate homocysteine metabolism?
Specifically, up your intake of those B-vitamins that regulate homocysteine metabolism, which are: Vitamin B 6 – in the form of pyridoxal-5-phosphate. Vitamin B 12 – preferably as methylcobalamin. Folic acid – as active folate, i.e., 5-MTHF (5-methyltetrahydrofolate) Other supplements can also be helpful.
Why are methionine, homocysteine, and cysteine important?
Interconversions among methionine, homocysteine, and cysteine are crucial to good health for four main reasons: They enhance the production of glutathione, one of our most important natural antioxidants. They help the binding of minerals such as copper and zinc, thereby making them bioavailable to your body.
How does homocysteine form?
Once it is formed from methionine, homocysteine can do two things: 1 Revert back into methionine by a process called methylation, which is aided by vitamin B 12 and folic acid (also a B-vitamin). 2 Convert into another amino acid, cysteine, by a process called transsulfuration, which is aided by vitamin B 6.
What is the danger of high homocysteine levels?
The Danger of High Homocysteine Levels. High homocysteine levels indicate chronic vascular inflammation. This sets the stage for atherosclerosis (hardening of the arteries) and plaque formation that blocks blood flow. Vascular plaque leads to blood clots, heart attacks, and strokes. Fortunately, certain B-vitamins can go a long way in keeping ...
What is the process of homocysteine?
Once it is formed from methionine, homocysteine can do two things: Revert back into methionine by a process called methylation, which is aided by vitamin B 12 and folic acid (also a B-vitamin). Convert into another amino acid, cysteine, by a process called transsulfuration, which is aided by vitamin B 6.
What is the normal range of homocysteine in blood?
Population surveys from clinical laboratories indicate a normal range of homocysteine in the blood to be 5 to 15 μmol/L. However, the associated heart disease risk increases rapidly at the upper end of this range.
Does homocysteine come and go?
The key point is that the formation of homocysteine is a natural process that is regulated by the presence of vitamins B 6, B 12 and folic acid. Normally homocysteine comes and goes quickly as it converts to either methionine or cysteine. However, if your levels of vitamins B 6, B 12 or folic acid are too low, these interconversions slow down ...
