Our bodies are designed to receive sodium chloride in combination with other minerals and trace elements as are found in natural salt. Unrefined salt allows liquids to freely cross the 80 trillion or so cell membranes that make up our body. The benefits include:

Regulating the water content throughout your body
Replenishing your supply of electrolytes when you sweat heavily
Regulating blood pressure
Promoting healthy pH balance in your cells, particularly brain cells
Helping to make stomach acid
Promoting blood sugar health and helping to reduce the signs of aging
Absorption of food particles through your intestinal tract
Promoting sinus health
Prevention of muscle cramps
Promoting bone strength
Regulating sleep — it naturally promotes sleep
Supporting libido
Promoting vascular health
It is very difficult for your body to absorb too much-unrefined salt since there are powerful and effective feedback loops that regulate this process. Natural salts promote a healthy balance and do not contribute to high blood pressure.
