How long does it take for salt/sodium to get into the bloodstream from swallowing it?

Short: It starts getting into blood in seconds after swallowing it. It can enter blood from the mucus membrane of the mouth, even before you swallow it. Have a healthy diet, exercise 30 minutes/day, drink plenty of water, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Get HPV vaccine. Wish you good health!
