With a BMI of 15.8, the priority should be healthy weight gain rather than depending on weight-gain supplements. Before suggesting any supplement, we need to assess her age, height, current weight, medical concerns, food habits, appetite, activity level, and other relevant details. I would generally suggest starting with a calorie-surplus diet with 3 balanced meals and 2 healthy snacks. Based on provided details, we can plan the appropriate calorie, protein, carbohydrate, fat, and other nutritional requirements to support gradual and healthy weight gain. Choose nutrient-dense foods such as milk/curd, eggs or other protein sources, nuts and seeds, paneer/tofu, pulses, rice, whole grains and healthy fats. Avoid relying mainly on junk foods or sugary drinks for weight gain. If she has unexplained weight loss, poor appetite, digestive symptoms, or any medical concern, it is important to get evaluated by a doctor.

Health Tips
Aim for 3 balanced meals + 2–3 healthy snacks every day.
Add calorie-dense foods like nuts, seeds, nut butter, paneer, curd, milk, avocado and healthy oils.
Include a good protein source in every main meal to support muscle gain.
You can use homemade smoothies/shakes with milk or curd, banana, oats, nuts and seeds.
Avoid filling up on tea/coffee or excess water just before meals if your appetite is low.
Combine the diet with strength/resistance exercises to encourage muscle rather than only fat gain.
Increase portions gradually instead of suddenly eating very large meals.
Track your weight regularly; gradual, consistent gain is preferable to rapid weight gain.
