B vitamins are known to work together, and many people take them in a B complex supplement that contains B12, folic acid, B6, and more. Vitamin C and iron are also beneficial when taken together, as vitamin C helps the body absorb more iron from both food and supplements. Vitamin K and calcium are also a great combination for skeletal and heart health. It's essential to be aware that while it's safe to take vitamin D with vitamin B12, it's not recommended, according to Dr.
Virgilio Sanchez, a board-certified family medicine doctor at the Conviva Care Center in Miami, Florida. This is because vitamin D is a fat-soluble vitamin that is better absorbed with food, while B-12 is a water-soluble vitamin that should be taken on an empty stomach. Your body absorbs some vitamins better with food, so it's best to take them with a meal or snack. It's also important to be aware of the potential risks of taking too much of certain vitamins. For instance, taking too much folic acid or folate can hide the symptoms of a vitamin B12 deficiency.
Older people should also be aware that many vitamins for their age group contain more calcium and vitamins D and B12 than younger people need. Fat-soluble vitamins are stored in the body's cells, so it's important to be aware of how much you're taking. Research indicates that vitamin D and vitamin K work together to ensure that calcium is absorbed into bones instead of accumulating in the arteries. Therefore, it's important to talk to your doctor before adding any supplements to your regimen. Certain foods are so rich in vitamin A that you should only eat them once a week to avoid consuming too much of it. A small study of 60 male patients with coronary artery disease found that a combination of omega-3 and vitamin E had beneficial effects on serum insulin and insulin resistance. It's essential to note that you should not take any individual mineral at the same time as a multivitamin supplement or antioxidant vitamin formula, such as one that contains beta-carotene and lycopene.
In general, water-soluble vitamins can be taken together without food, and fat-soluble vitamins can be taken together with foods that contain healthy fats. Additionally, some vitamins can interfere with the effectiveness of medications and even exacerbate side effects. The joint intake of certain vitamins can affect their absorption in the body, sometimes worsening the situation and other times improving bioavailability. It's important to be aware of these potential risks when taking any combination of vitamins.
