If you often wake up feeling sluggish, these healthy morning habits can help set a more energized tone for your day.
Let’s explore the science-backed list of the best vitamins for energy and tiredness that can help you feel more alert, focused, and energized throughout the day.
1. Vitamin B12

Vitamin B12 helps convert food into glucose, which your body uses for energy. A deficiency can lead to extreme fatigue, brain fog, and even depression.
Sources: Eggs, dairy, fish, and fortified cereals.
Tip: If you’re vegetarian or vegan, consider a B12 supplement.
Vitamin B12 helps convert food into energy and is essential for red blood cell production, according to the NIH Office of Dietary Supplements.
Pairing B vitamins with the right pre- and post-workout meals can enhance nutrient absorption and energy use.
2. Iron

Iron supports the production of hemoglobin, which carries oxygen throughout the body. Low iron levels can cause anemia, a major cause of chronic fatigue.
Sources: Red meat, spinach, lentils, and tofu.
Tip: Pair iron-rich foods with vitamin C to improve absorption.
Iron deficiency is one of the most common causes of fatigue worldwide, as highlighted by the World Health Organization (WHO).
3. Vitamin D
Low vitamin D levels are linked to tiredness and low mood. It helps regulate calcium and boosts immune and energy functions.
Sources: Sunlight, fortified foods, and fatty fish.
Tip: Get 15–20 minutes of sun exposure daily or take a D3 supplement.
4. Magnesium
Magnesium is involved in over 300 biochemical reactions, including those that convert food into energy. Deficiency can lead to muscle weakness and fatigue.
Sources: Nuts, seeds, whole grains, and dark leafy greens.
5. Coenzyme Q10 (CoQ10)
This antioxidant helps your cells produce energy. CoQ10 levels naturally decrease with age and certain medications (like statins).
Sources: Organ meats, fatty fish, and whole grains.
Tip: Supplements are especially useful for people over 40.
6. B6 (Pyridoxine)
Vitamin B6 supports adrenal function and helps your body make serotonin and norepinephrine, which affect mood and energy.
Sources: Chickpeas, poultry, bananas, and potatoes.
7. Folate (Vitamin B9)

Folate is critical for DNA production and energy metabolism. It also supports mood and brain function.
Sources: Leafy greens, legumes, and citrus fruits.
Note: Folic acid (synthetic) is often added to fortified foods.
8. Vitamin C
Known for its immune support, vitamin C also helps transport fatty acids into mitochondria—your body’s energy factories.
Sources: Oranges, kiwi, strawberries, and bell peppers.
9. Iodine
Iodine supports proper thyroid function, which regulates metabolism and energy levels.
Sources: Iodized salt, seaweed, and seafood.
10. Zinc
Zinc supports immune function and energy metabolism. A deficiency can make you feel tired and run down more often.
Sources: Meat, shellfish, legumes, and seeds.
11. Ashwagandha (Bonus Herbal Adaptogen)
Though not a vitamin, this adaptogenic herb helps manage stress and improve energy by balancing cortisol levels.
Tip: Take in capsule or tea form for best results.
Combining Ashwagandha with morning meditation may further reduce fatigue caused by chronic stress.
