Best Supplements for Energy & Fatigue

B-Complex Vitamins

B vitamins, especially B12 and B6, are cofactors your cells use to convert food into usable energy. Low B12 in particular is a well-documented cause of fatigue when levels are actually deficient. A B-complex supplement supports this pathway broadly rather than targeting one specific vitamin.*

Magnesium

Magnesium is involved in hundreds of enzymatic reactions in the body, including energy production at the cellular level. It's also one of the more commonly under-consumed minerals in a typical diet, which is part of why it shows up so often in energy-support formulas.*

CoQ10

Coenzyme Q10 plays a direct role in mitochondrial energy production — the process your cells use to generate ATP, the body's basic energy currency. Levels naturally decline with age, which is why it's frequently paired with other energy-support ingredients.*

Iron (When It's Actually Low)

Iron-deficiency fatigue is real and common, particularly in menstruating women, but supplementing iron when levels are already normal doesn't help and can cause side effects. This is one category worth checking with an actual lab value (like the iron/ferritin markers included in VitaFix's Wellness Panel) before supplementing blindly.*

Vitamin D

Low vitamin D is strongly associated with fatigue and low mood in the research, and deficiency is common, especially in people who spend most of their time indoors. Like iron, this is a category where a lab value is more useful than guessing.*

Adaptogens (Rhodiola, Ashwagandha, and Similar)

Adaptogens are a category of herbs studied for their potential to help the body manage stress, which is a common but often overlooked contributor to the "always tired" feeling. Rhodiola in particular has research behind its use for mental fatigue and endurance.*
