You really need B vitamins
The B vitamins are a group of eight water-soluble vitamins. They are coenzymes in a variety of metabolic processes in the body, and often work together—though each has a unique role as well. B vitamins are critical for building and repairing DNA and RNA, for producing energy, supporting mitochondrial function, and for synthesizing neurochemicals. And because they are involved in so many processes, deficiencies in B vitamins can lead to many problems. Are you getting enough B vitamins?
Vitamin B2 - Riboflavin
Riboflavin—vitamin B2—is a critical vitamin for overall health, supporting metabolism (especially fat metabolism), iron metabolism, eye health, and methylation while preventing oxidative stress. It’s present in a varied diet, with good sources including greens, seeds and nuts, eggs, and lean meats and fish. It can be taken supplementally and is usually part of a multivitamin. There’s no known toxicity of high doses, though most supplements have way more than the RDA (sometimes more than 100 times). The RDA is 1.1 to 1.3 mg; many people may need more than that by 2x or 5x. The best way to know if you need riboflavin is to test for it!
MTHFR. Do you have it? And is it affecting your health?
MTHFR is a gene that gets a lot of press. It can be very relevant for many people, and may be linked to symptoms like fatigue, depression, blood clots, OCD, poor memory, insomnia, and heart disease.1 But it also sometimes gets unfair blame. So what does it do? And does it matter for you?
