開始健身後你肯定有想過喝高蛋白幫助增肌，這當然沒錯啊，但如果只懂喝高蛋白你其實還未懂健身，因為肌肉不會因為高蛋白而增力，要瞬間提升肌肉爆發力你需要的是提高肌肽水平（Muscle carnosine levels）！

肌肽（Carnosine）是一種重要的抗氧化劑，能保護細胞免受破壞和緩衝（buffer）引起肌肉疲勞的酸性，而且雖然這種作用常被視為提高肌耐力的關鍵（慢肌纖維中作用更大），肌肽的水平同時也與肌肉能使出多少最大力量（peak power output）有關。

對此，一個澳洲相關研究就發現到補充肌肽能增加鈣質在肌肉中的敏感度，那是觸發肌肉收縮的重要礦物質。這裡當然不是指補充鈣質就會同樣的效果，因為鈣質在肌肉中的敏感度才是其作用原理。

那麼肌肽水平怎樣提高呢？日常飲食中也能攝取這種抗氧化劑，但相關健身補充品能提供的份量當然多出很多，才有機會達至肌肉力量提高的效果。不過，在實際運用中我們很少直接服用肌肽補充品，因為以補充β-丙氨酸（Beta-alanine）的方式更有效提高肌肉中的肌肽水平，所以提高健身訓練表現的補充品也多含有β-丙氨酸（Beta-alanine）。

• Boosts Strength
• Enhances Endurance
• Increases Carnosine
• Reduces Lactic Acid

Beta Alanine contributes to the build-up of Carnosine in the body. Carnosine helps to prevent the pH level drop, which is the primary cause of muscle fatigue and workout failure. Beta Alanine is the rate-limiting amino acid for Carnosine synthesis.

Ensuring that you've got optimum levels of Beta Alanine coursing through your system as you walk into the gym will allow you to reduce lactic acid build-up in your working muscles so you can push harder for longer.

International Protein's Beta Alanine features CarnoSyn®, the most effective, highest quality Beta alanine available anywhere. CarnoSyn® is backed by years of scientific research and is the only patented form of Beta Alanine that exists.

International Protein Beta Alanine has just one ingredient . . . 100% Carnosyn Beta Alanine. CarnoSyn® is the only clinically proven, patent-protected Beta Alanine to deliver fast, effective and safe results.

Anyone who is looking for that extra performance boost that will allow them to perform with more endurance and intensity, whether on the gym floor, the running track or the sports field, will gain that edge with Beta Alanine supplementation. Athletes and recreational gym-goers who lift weights will especially benefit from this supplement. 

Mix 1.2 g (one scoop) of International Protein Beta Alanine in 200 ml water or add to your pre-workout. Take it 30 minutes before your workout for the best effect. Use Beta alanine daily for 15 days straight to allow it to build up in your body.
