Malic acid didn't help me. General detoxification(detox teas, or licorice root, dandelion, ginger, dandelion, etc. helped me.
So does molybdenum). Extra magnesium helps. Those on a low sodium diet might benefit from taking in some additional sodium. Eating plenty of low carb vegetables is important to get enough potassium. Also make sure to drink plenty of water.

I believe numbness and tingling are mostly due to a magnesium deficiency. Try taking more magnesium in a good form(perhaps citrate or ascorbate?).
