Sex supplements often contain Viagra ingredients

Herbal supplements aimed at improving men's sexual abilities often contain the active ingredients in erectile dysfunction pills such as Viagra, according to a new study.
Additionally, researchers found that some of these over-the-counter herbal remedies contained more of the ingredient than is allowed in prescription-only pharmaceuticals.

 Although 57 of the products claimed to be "all natural," 81 percent of them contained the tadalafil or sildenafil (marketed as Cialis and Viagra, respectively) or similar ingredients that are not approved by the FDA.
