A supplement is a substance that is taken in addition to the diet to improve health or physical performance. Some common supplements include vitamin and mineral supplements, protein supplements, and herbal supplements. The use of supplements can be controversial, as there is limited evidence to support their benefits and some supplements may have harmful side effects. The benefits of taking supplements are vast and include both physical and mental health improvements. For example, supplements can help improve overall energy levels, aid in weight loss or weight management, support cardiovascular health, boost cognitive performance, and enhance overall mood. Additionally, many supplements are packed with essential vitamins and minerals that are necessary for optimal health, making them a great way to fill in any nutritional gaps in your diet.
