The Most Common Gaps

Millions of people fall short on key micronutrients without knowing it. Vitamin D insufficiency affects more than 40% of adults, which can hurt bone health, immunity, and mood. Magnesium drives over 300 enzyme reactions, yet most diets supply too little.

Iron deficiency is especially common in women, causing fatigue and poor focus that get written off as stress. Vitamin B12, vital for nerve function, often runs low on plant-based diets.

The tricky part is that mild deficiencies rarely cause obvious symptoms. You just feel a little off, a little tired, a little foggy — and assume that is your normal baseline.
