Recent (well more recent studies) have shown that taking 20g of creatine per day has benefits for the mind. For older people or even for someone a bit younger going through a stressful time or jet lag. To get 20g from eating beef you would need 4-4.5kg of beef (8.8-10lbs). Which is difficult to do in a day. Makes sense to supplement. Even for 10g for muscles and bone benefits.
But for sure 1st step is to make sure diet is on point before adding anything.
