Persistent fatigue is most commonly linked to deficiencies in Vitamin B12, Vitamin D, and Iron. While several vitamins support energy metabolism, these three are the most frequent culprits for unexplained tiredness.
What vitamins can cause extreme fatigue?
While this may be true to an extent, it's essential to note that taking too much of specific vitamins can cause fatigue. For example, vitamins B6 and B12 play a key role in energy metabolism. However, taking large doses of these vitamins can also cause fatigue and other symptoms such as headaches, diarrhea, and nausea.
What do you crave when your B12 is low?
When Vitamin B12 is low, you often crave animal-based products like red meat (beef, lamb), fish, and eggs. These cravings arise because the body seeks nutrient-dense foods to correct the deficiency, resulting in sudden, intense hunger for protein-heavy meals. Some individuals may also crave sugar due to fatigue.

Vitamin D levels are primarily drained by medications that accelerate its breakdown (steroids, anti-seizure drugs), conditions causing fat malabsorption (Crohn's, celiac disease, gastric bypass), and lack of sunlight exposure. Obesity also lowers levels because fat tissues bind the vitamin, making it unavailable, while kidney/liver diseases prevent activation.

To eat enough on Zepbound, prioritize protein first, adopt a "small and frequent" meal schedule (4-5 times a day) rather than three large meals, and consume calorie-dense, nutritious foods.

Fortified energy drinks, such as certain GHOST energy drinks or Vitamin Energy shots, often contain the highest amounts of vitamin B12, sometimes exceeding 14,000% of the daily value.

Two eggs a day provide roughly 46%–50% of the recommended daily value (DV) of Vitamin B12, making them a significant contributor but not a complete daily source, as they contain about 0.6 mcg of B12 per egg against a 2.4 mcg recommendation. While they are highly nutritious, relying solely on two eggs may not meet the full daily need for most adults.
