    Supplements should be used in addition to eating well, rather than as a replacement for it. While some people may benefit from taking supplements, they should be used under the guidance of a healthcare provider and are not intended to replace food. The following supplements may help prevent or treat keto flu:

    Electrolytes are minerals such as sodium, potassium, and magnesium, which are essential for proper bodily function. When following a ketogenic diet, it’s common to lose electrolytes due to increased urination and sweating. Supplementing with electrolytes can help replenish these minerals and alleviate symptoms such as muscle cramps and fatigue.

    MCT oil is made up of medium-chain triglycerides and is processed quickly by the body. Studies suggest it can help increase ketone levels, which might improve cognitive function in those with brain fog or fatigue.

    Omega-3 fatty acids are essential fats that have been shown to reduce inflammation, a common cause of many keto-flu symptoms.

    B-complex vitamins are a group of vitamins that are essential for energy production and proper nervous system function. Supplementing with a B-complex vitamin may help alleviate symptoms such as fatigue and brain fog.

  • Can keto flu occur after being on the ketogenic diet for a while?

    While keto flu is typically experienced by people during the first few days on a low-carbohydrate diet, it can also happen after several weeks or months of eating this way because electrolytes may be disrupted even when there isn’t weight loss.
