There are number of pills in market, but what i am sharing is personally tried by my brother. Liver-52, my brother was so happy with the results that it improves digestion and also helps to clear stomach well. But he also said that, too much reliance on it could reduce my body's ability to work on the same mechanism, although its good for short span.
Rest you can look for green tea- as it is evident to increase metabolism of our body, then apple vinegar, use of coconut oil in cooking will definitely help. 
Use of nuts and proteins in diet also helps to enhance our body metabolism.
While there are various supplements marketed as metabolism boosters, it's important to note that relying solely on pills for rapid results is not a sustainable or healthy approach. A healthy metabolism depends on various factors, including regular physical activity, a balanced diet, and sufficient sleep. Pills such as caffeine, green tea extract, or thermogenic supplements may provide a temporary increase in metabolism, but their effects can vary among individuals. Instead of focusing solely on pills, consider adopting long-term lifestyle changes like incorporating regular exercise, consuming a well-balanced diet rich in whole foods, staying hydrated, and getting adequate rest to support a healthy metabolism. Always consult with a healthcare professional before starting any new supplement regimen.
