Omega‑3 capsules typically provide EPA and DHA, the two primary omega‑3 fatty acids that occur naturally in foods like oily fish. In fitness, these nutrients can enhance a well‑balanced diet and promote general wellbeing, especially for individuals who seldom consume fish. However, omega‑3 supplements do not directly increase muscle mass or accelerate fat loss. Your core focus should stay on strength training, sufficient protein intake, proper calorie intake, protein snacks, staying hydrated, and getting enough rest.
