Optimize your workout results and build the lean muscle mass that boosts strength.* The Amino Complex formula also enhances cellular energy production.* 

Amino acids are the building blocks of protein. They fuel muscle gain and other physiological functions, including enzyme production, hormone regulation, cognitive ability, neurotransmitter balance, metabolism, and energy production.* As we age, we lose muscle mass, which can cause other health issues, so it is important to promote the growth of lean muscle mass.* 

Of the 20 amino acids in total, nine are classified as essential amino acids (EAAs), those the body cannot produce itself. Therefore, they must be consumed through diet and supplementation to support the body’s internal production of energy.* 

Thorne’s Amino Complex is a comprehensive blend of essential amino acids, which is high in branched-chain amino acids (BCAAs) – a group of amino acids validated through clinical trials to promote the growth of lean muscle mass and enhance muscle strength.* 

EAAs benefit the body in multiple ways:

• Support muscle repair and recovery*
• Reduce muscle soreness*
• Increase energy production*
• Promote healthy blood sugar*
• Support cardiovascular health*
• Strengthen connective tissue*

Amino Complex’s formula supports sports, fitness, and training-related activities.* Additionally, it promotes the growth of muscle mass in individuals who need to preserve muscle mass, including the elderly.*

Amino Complex comes in two flavors – lemon and berry – and is lightly sweetened. It mixes easily with warm or cold liquids, and contains flavors and sweeteners derived from natural sources.

It is best taken after a workout to facilitate the recovery process.* It’s an ideal formula for active individuals, individuals managing calories, or anyone who has difficulty consuming whole foods or protein powders, particularly after heavy exercise.

Because athletes need to know their supplements are trustworthy and compliant, every batch of an NSF Certified for Sport® product is tested for compliance with label claims and to ensure the absence of more than 200 substances banned by many major athletic organizations.
