  • What is Protein and why do I need it?

    Protein makes up 40% of the human body (in the absence of water). Protein is needed by everyone and is an essential nutrient for the growth and maintenance of muscle tissue. Your body is in a constant state of protein turnover so it is important that you consume enough protein throughout the day to balance this out. If you are looking to develop your muscle or simply maintain it as part of active lifestyle, your requirement for protein intake increases.

  • I am new to Sports Nutrition & Protein. Where do I start?

    When you exercise you push yourself harder which means that your diet needs to work harder for you as well. If you’ve ever asked yourself ‘What is Protein?’ and felt silly, don’t. Lots of people fail to see that protein is a key part of every exercisers diet needed in order to nourish working muscles and help support the maintenance, growth & development of muscle following exercise. Put simply, the more you train, the more protein that your body needs. Supplementing your diet with high quality protein helps you to get the most from your exercise.

  • When is best time to have Protein? And how much do I need?

    For healthy living, it is recommended you consume 0.8g of protein per kilogram of your bodyweight per day. However, exercise increases the demand on your body for more protein to achieve a balance and support your muscle maintenance and development following exercise.

    It is recommended that when you exercise, you increase your protein intake to 1-2g of protein per kilogram you weigh, per day. Ideally the best time to consume proteins is every 2-3 hours in your meals or as part of snack in between.

    After exercise, 20-30g of protein is recommended as the optimal dose of protein. Research has shown that this amount supports the development and growth of muscle tissue at this time, but you may wish to take more depending on your level of exercise, goal and weight.
