Lack of what vitamins can cause cracked lips? since i had gastric bypass (5 yrs ago), my lips have been chronically cracked. it's really bad. i take all my vitamins. labs ok. do i need more vitamins?

Check with your doc: All kind of weird stuff can happen afterwards. Better check with your doc.

Cheilitis: If you are getting a cracks at the corners, b2, iron and zinc may all be responsible.

Malabsorption: Many of gastric by pass patients have problems absorbing some of the essential vitamins via the stomach or duodenum-jejunum. No matter how much vitamins you swallow, it will not be absorbed into your body. You may need some vitamin injections, or try isotonic formulations of vitamins.

Certain vitamins : And minerals are not adequately absorbed after gastric bypass like vitamin b 12, vitamin c, folate, iron , calcium etc. Take chewable multivitamins instead of tablets, vitamin b oral drips, chewable calcium etc. Use lip balms, blistex , aveeno (oatmeal) lip moisturizer balms etc get tested for specific vitamin deficiency , read link below. Hope u feel better !

May be food allergy: Riboflavin (b2), zinc, or iron deficiency can cause cheilosis (cracked corners of mouth), so it may help to take higher doses of these due to possible absorption problems. Check with your doc. In addition to what's been said, you could have a chronic food allergy causing your cracked lips. Common causes include gluten/gliadin (wheat), dairy, soy, and eggs. An elimination diet may help.
