Fat-soluble and water-soluble vitamins For example, while it's safe to take vitamin D with vitamin B12, it's not recommended, says Dr. Virgilio Sanchez, a board-certified family medicine doctor at the Conviva Care Center in Miami, Florida. Vitamin C is an antioxidant essential to the health of the immune system. Vitamin B-12 helps maintain the nervous system and form red blood cells.
Studies show that taking these two supplements at the same time can reduce the amount of vitamin B-12 you get. Therefore, experts recommend taking these supplements at least two hours apart. For example, vitamins B1, B2, B3 and biotin are needed for energy; vitamin B6 for amino acid metabolism; and vitamin B12 and folic acid for cell division, according to Michigan Medicine. Therefore, talk to your doctor to check your vitamin levels before adding these supplements to your regimen.
Poor diet, age, genetics, being vegan, medical conditions, some medications and alcohol abuse can increase the body's need for B vitamins, according to the Colorado State University Extension. When it comes to the type of fat-soluble vitamin (vitamins A, D, E and K), it's best to take them at mealtime. Adequate intake of vitamins, including vitamin D and the B complex group, is essential for good health. You may need a supplement that contains vitamin D if you have symptoms of a deficiency, such as bone pain, easy bone fractures, stooped posture, muscle cramps, fatigue, weakness, tingling, and depression or anxiety.
The time needed to meet your DV varies from person to person, but the Vitamin D Council recommends half the amount of sun exposure needed for your skin to begin to burn. While both of these B vitamins are important, taking too much folic acid or folate can hide the symptoms of a vitamin B12 deficiency. Vitamin D plays an important role in the body, contributing to bone health, hormonal regulation, normal cellular function, the reduction of inflammation and the synthesis of connective tissue. If you need to supplement your diet with vitamin pills, don't worry about combining vitamin D and B complex, as toxicity is rare.
Because B vitamins are soluble in water, any excess supplements are excreted in the urine, making toxic effects unlikely. However, one rule remains the same: the most important time to take a vitamin pill is a moment you'll remember day after day. If you follow a balanced diet that includes fish, poultry, meat, eggs, dairy products, green leafy vegetables and legumes, along with fortified cereals and bread, you are likely to meet your daily needs for all your B vitamins. However, megadoses of vitamin D from supplements can cause toxicity and cause a buildup of calcium in the blood, known as hypercalcemia.
Vitamin A and vitamin K can have negative interactions with blood thinners, so you should avoid taking both.
