Pork is one of the most widely consumed meats after chicken and beef, but it has a higher content of vitamin B3 when compared to both.

You can have pork few times in a week, but always opt for lean cuts to keep the fat content to the minimum.
Beef is another great source of vitamin B3 providing 9 mg or 45% DV in a 100 grams serving of cooked lean rib. Other beef cuts that are good sources of niacin include lean sirloin steak (38% DV), beef fillet (37% DV) and tenderloin (36% DV) in a 3 oz. serving.
