Supplements can assist in achieving fitness goals by providing essential vitamins, minerals, and nutrients that may be lacking in the diet. For example, protein powders can help meet daily protein needs for muscle growth and recovery, while creatine may enhance strength and power during workouts. Other supplements, like omega-3 fatty acids or BCAAs, might support recovery and reduce muscle soreness. However, it’s important to consult a healthcare professional before starting any supplementation to ensure safety and appropriateness for individual health needs.
