The Hidden Reason Vitamin D Fails in People with Obesity

Extra body fat interferes with how vitamin D works after it enters your body, which explains why low levels often persist despite supplements or sun exposure Vitamin D can become trapped in fat tissue and fail to convert into its usable form, leaving blood tests low even when intake appears sufficient Deep belly fat and liver fat have the strongest impact on vitamin D availability, making waist size more important than body weight alone Taking higher doses of vitamin D doesn't always fix the problem if metabolic signals from excess fat remain unchanged Reducing visceral fat, restoring metabolic health, and supporting proper vitamin D activation help vitamin D function normally again
