###Human: Chronic atopic gastritis has caused osteoporosis and joint weakness. Please suggest supplements. ###Assistant: Hello. After going through your query and detailed report I suggest to calm your gut first which in turn helps to increase absorption of vitamin and calcium and start with L- glutamine supplement 5g capsule daily preferably before going to bed or at least an hour before meals. Later you can opt for multivitamin supplements with good food intake. Along with that follow these tips. 1. Increase high protein diet, including almonds, vegetables, fish, chicken, and eggs. 2. Do muscle strength exercises if allowed by ortho. 3. Increase fluid intake. 4. Do rest for 8-9 hours of sleep. 5. Manage stress with meditation. 6. Do breathing exercises. 7. Manage to follow small frequent meals. 8. Do take 2500 kcal diet. If required you need to add supplement (whey protein) L-Glutamine.
