A number of websites claim that sugar cravings may be a sign of a magnesium deficiency.

For example: Genesis Medical Scheme is one of many sites that carry an article that claims:

Magnesium regulates glucose and insulin levels, as well as the neurotransmitter dopamine. A deficiency will cause intense sugar cravings, especially for chocolate.

Does magnesium deficiency lead to people craving sugar?

  • But, the link says "Because chocolate is high in magnesium, it's been suggested that a deficiency may play a role in these cravings," she says. "This is a research area that needs more investigation, but it does present an intriguing possibility in terms of what might be the underlying cause of these cravings." They say it is because chocolate contains the deficient mineral, not because it is sweet.
