What helps, what is a waste of money

Electrolytes: Essential

When you fast, insulin drops and your kidneys excrete more sodium, potassium, and magnesium. This causes headaches, fatigue, and cramps. A pinch of Himalayan salt in your water fixes most "fasting flu" symptoms.

Magnesium: Highly Recommended

Many people are magnesium-deficient, and fasting can worsen it. Magnesium glycinate (200-400mg before bed) supports sleep, muscle function, and relaxation. Does not break a fast.

BCAAs / EAAs: Optional

The evidence is mixed. Some people find 5-10g before fasted training helps with energy. Others say it is a waste. If you train fasted and feel weak, try them. If not, skip.

Creatine: Yes, But Timing Does Not Matter

Creatine supports strength and muscle preservation. Take it whenever — morning, evening, with food or without. It does not break a fast and the timing is irrelevant.
