B vitamins are vital in the conversion of food into energy your body can use, as well as supporting its nervous system.

Vitamin B12 can be found naturally in meat, fish, dairy products, eggs and fortified foods; vegans and vegetarians may be at an increased risk for vitamin B12 deficiency.

People suffering from certain medical conditions may gain from taking a high-strength B complex supplement, including pregnant women and those with MTHFR gene mutations.

What is B Complex?

Vitamin B complex is an array of eight water-soluble vitamins essential to human metabolism and is consumed through our daily food or supplement regimen. They play key roles in energy production from food, producing glucose from carbohydrates, producing amino acids and transporting oxygen and nutrients around our bodies. A balanced diet provides ample vitamin B complex sources; however supplements may also help improve energy levels and relieve stress.

Vitamin B complex supplements are generally safe to take as long as the dosage doesn’t exceed recommended amounts. Furthermore, some brands of B complex are available with increased concentrations of individual vitamins. It is important to assess your dietary needs and health goals prior to taking supplements in powder or gummy forms.

Niacin can cause skin flushing and liver damage when taken in large doses; additionally, this medication interacts with several drugs; always consult your physician before adding additional supplements such as this one to your regimen.

B6

B6 or pyridoxine and pyridoxal 5’phosphate is a water-soluble vitamin found in many food sources. It serves as an important coenzyme and aids over 100 enzymes with performing their various functions, such as breaking down protein, carbohydrates and fats; maintaining normal homocysteine levels (which may lead to heart issues); supporting immune function and brain health; as well as aiding brain health overall.

Studies have demonstrated the vital role B6 plays in producing hemoglobin, essential for oxygen distribution throughout the body. Furthermore, it plays an integral part in synthesizing DNA and RNA as well as in converting carbohydrates to energy for use as energy source while helping regulate blood sugar levels.

B6 is essential in the production of serotonin and norepinephrine, two key neurotransmitters responsible for mood. Research indicates that lower levels of vitamin B6 could be linked with depression; more research should be conducted into whether supplements could help alleviate its symptoms for those who suffer from low levels of B6.

Folate is a type of vitamin B9 found naturally in many foods and supplements alike. Studies have linked folate with reduced risks of certain forms of cancer and slower rates of cognitive decline for older adults; however, one study involving 156 people with mild dementia indicated that high doses of B6, B12, and folic acid did not decrease mental decline compared to a placebo (17). More research should be conducted into this topic.

B9

The B vitamins (B6, B9 and B12) help convert carbohydrates to fuel for energy production in our bodies, as well as play an integral part in producing red blood cells and helping the nervous system work correctly. Folic acid and vitamin B12 are required for DNA synthesis, methionine metabolism and methylation reactions which regulate gene expression and cell functions – inborn errors in these processes may lead to serious neurological and hematological pathologies; low folate/B12 status is linked with cognitive impairment among older adults as well as neural tube defects in infants born to mothers who intake inadequate amounts.

Folate and vitamin B12 are available both as synthetic supplements and fortified food items, since they’re water-soluble. As one-carbon metabolic cofactors, they also play an integral part in cell signaling pathways and the uptake of iron into cells.

Population-based studies have linked low levels of folate and B12 with an increased risk of cancer [122]. Increased serum folate exposure increases cancer risk while increased methylated TC decreases it; one potential therapeutic strategy would be targeting methionine synthase (MS), the rate-limiting enzyme in one carbon metabolism; inhibiting MS with 5-methyltetrahydrofolate (5-mTHF) or its metabolically active form pyridoxal 5′-phosphate (PLP) can decrease DNA methylation rates as well as increases TC in cancer cells [133,134].

B12

B12 (cobalamin) is a water-soluble vitamin essential to health and wellbeing. It plays an essential role in producing red blood cells and DNA – the genetic material of cells. Naturally found in meat, fish, dairy products and eggs as well as being fortified into foods and supplements alike; further research is underway regarding its potential in protecting against cardiovascular disease, dementia and depression.

Adults generally require 2.4 milligrams (mcg) of vitamin B12 every day for adults. Certain populations, however, such as vegans who avoid animal products as well as those undergoing intestinal surgeries or living with digestive diseases such as Crohn’s and celiac may require more.

Vitamin B12 is essential to the health of both the nervous system and brain. A deficiency may result in memory problems and depression; low levels may even cause anemia.

Studies indicate that vitamin B12 plays an integral part in lowering homocysteine levels, which have been linked to an increased risk for heart disease and stroke as well as dementia-related illnesses such as Alzheimer’s. Studies also suggest it could reduce homocysteine levels to protect against dementia as well as Alzheimer’s.

Studies indicate that increased vitamin B12 intakes and serum concentrations may be linked with lower cancer rates; however, clinical trials have yet to demonstrate this connection. Supplementing with B12 should generally be safe; please check with your healthcare provider first before beginning any new regimens.

Folate

Folate (also known as folic acid) is one of eight B vitamins. As a water-soluble nutrient, foliate plays an essential role in body functioning such as breaking down carbohydrates, fats, and proteins into energy sources; transporting oxygen throughout the body; cell development during gestation and birth of red blood cells formation. Folate can be found in meat, leafy vegetables, dairy products, beans/peas/fortified grains etc.

As it’s essential that all vitamin supplements be taken with care, particularly if taking medications or suffering from depression, B vitamins should only ever be taken upon medical advice and discussion with healthcare providers before being consumed. Although B vitamins are considered safe, some interactions and side effects could occur, so it’s wise to get advice first from healthcare professionals prior to beginning to take them.

People lacking B12 and folate may suffer fatigue, memory loss and depression. Pregnant women must consume sufficient b vitamins during gestation to help avoid birth defects like spina bifida and anencephaly; eating fortified foods as well as taking b complex supplements during these months are highly recommended to ensure they get enough b vitamins to protect their developing babies from these risks. Other symptoms of deficiency in B12 can include decreased appetite, difficulty swallowing food and digestive issues such as abdominal pain and diarrhea; it can also be found naturally in foods such as fish meat dairy dairy nutritional yeast plus fortified products like breakfast cereals.

Vitamin D

Vitamin D is a group of fat-soluble secosteroids that increase intestinal absorption of calcium and magnesium as well as having multiple other biological effects. Between October and April, those living nearer the equator may get most or all of their Vitamin D from sunlight exposure; those further away should ensure they include sufficient sources in their diet such as milk or egg yolks with added Vitamin D fortifications; additionally fatty fish species (notably salmon tuna and mackerel) as well as fortified cereals have higher amounts of Vitamin D content.

Clinical research has established the importance of vitamin D in maintaining bone health and avoiding fractures; however, its effects do not appear to extend to protection from chronic diseases or functional measures, at least not at doses currently used in studies (please refer to “Vitamin D” fact sheet for details). Furthermore, according to Food and Nutrition Board Committee’s DRIs for Vitamin D recommendations there was insufficient evidence supporting that supplementing with this vitamin will increase serum 25(OH)D levels sufficiently across most populations to satisfy public health recommendations.

B vitamins play an essential role in turning carbohydrates, fats and proteins into energy for our bodies, while simultaneously synthesizing neurotransmitters — chemicals which transmit nerve cell signals between nerve cells. Vitamin B12 plays a significant role in red blood cell production as well as energy production by converting homocysteine into methionine for energy production. Adenosylcobalamin is another naturally occurring form of Vitamin B12 which helps boost metabolism while protecting nerve cells via myelin sheath formation.
