Potassium Nitrate and Male Sexual Libido
Is there a decrease in male sexual libido from using potassium nitrate in anti-sensitivity toothpaste, specifically “Colgate Sensitive Multiprotection”, which contains 5% potassium nitrate?
There are very low levels of potassium nitrate in any toothpaste. When you go on to consider that it is not ingested, but expectorated, there is almost none going into your system to affect libido.
