Although some supplements like Testosterone Support can help to address factors that are linked to erectile dysfunction (such as testosterone levels), many men find it more convenient to take erectile dysfunction medicine (e.g. sildenafil or tadalafil) because it usually treats erectile dysfunction symptoms faster than taking a supplement. It can take a long time (sometimes months) for the beneficial effects of supplements to build in the body. However, erectile dysfunction tablets can help men to achieve stronger erections in as little as 30 minutes, which is why they are often regarded as “go-to” treatments for erectile dysfunction.
