So these are the foods you need to add to your regular diet immediately in order to increase the blood platelet count naturally. You need to maintain a normal platelet count between 150,000 to 450,000 per microliter of blood. If your platelet count is low you can manage it with proper diet and supplements. But when the count is severely low you have to consult a doctor. Also, take expert opinion before consuming supplements. Eat healthily, take your medicines regularly, and go for regular checkups.
