You just need to graduate from college with the qualifying credentials and gain admission to a medical school!
As stated below, a 17 yr old graduated from medical school in 1995. To answer your question, I don't see an age limitation in medical school applications.
"Balamurali Ambati became the youngest doctor in the world after graduating at age 17 from Mt. Sinai School of Medicine in 1995. He completed an ophthalmology residency at Harvard University and a fellowship in cornea and refractive surgery at Duke University. He practices and teaches at the University of Utah."
As mentioned above, you do not have an age limit to go to medical school as long as you have completed MCAT and premed. Some professionals change their mind mid- carrier and attend medical school in thirties or even forties after completing the prerequisites. However, the earlier you enter more convenient you may find it because the family responsibilities and financial needs could interfere with successful completion of medical school. The other reason to start early is that medical school and residency takes several years before you become an independent physician/ surgeon. I know an engineer and a lawyer who changed their mind about the career after 35 and attended medical school and completed residency. However, one reason for their success was they were completely dedicated and were comfortable with the change.

So a typical student at a US medical school will be 22 or older.
As mentioned above, age itself doesn't matter so much, but you do need a college degree and you need to take the MCAT exam (Medical College Admission Test). Like the SATs, the better your MCAT score, the better your chances are of getting into a medical school. Check out https://www.aamc.org/students/applying/mcat/ for more info on the exam.

There is no limit. I started medical school at age 40 and it was the best career decision I ever made.
You are never to old.
