Vitamin C-rich foods are well-known for their immune-boosting qualities, but they also help to raise platelet counts. Vitamin C, which is usually found in citrus fruits, also helps the body absorb iron, which is another important component for increasing platelet count. Increasing your consumption of a specific nutrient can also help you avoid getting a cold or the flu throughout the winter. The only thing to keep in mind is that heat might cause vitamin C to be destroyed. As a result, it's preferable to eat vitamin C-rich foods fresh. This vitamin is found in broccoli, oranges, grapefruits, bell peppers, and strawberries, among other foods.
