Amino Acid Patches vs. Powders

The Downside Of Protein Powders

Many athletes are accustomed to taking their daily protein supplements in powdered form. Besides the inconvenience of juggling tubs of powder and mixing shakes, the effectiveness of oral delivery is in question. 

  1. GI-Distress: The gastro-intestinal tract presents a significant barrier to the efficient absorption of both orally administered metal drugs and dietary essential trace minerals. Once a protein powder mixture enters your stomach, it is immediately coated with powerful digestive acids.
  2. Slow Digestion: Depending on what else you may have eaten, the protein mixture in your stomach stays there for 2 to 4 hours. During this digestive process, the protein mixture continues to be degraded by these powerful digestive acids.
  3. Lower Absorption: After 2 - 4 hours, the remaining supplement’s nutrient value begins to move into and through the small intestines where it is slowly absorbed into the bloodstream. After first swallowing the mixture, about 10% (or less) of the original mixture's dosage strength survives the harsh acidic environment of the digestive system before entering the small intestine where it is absorbed into the bloodstream.

Transdermal Amino Patches Offer Alternatives To Powders

Time-release transdermal adhesives (patches) are the most effective, and most convenient way to absorb an amino acids into your bloodstream. It takes at least 100mg delivered orally to equal a 10mg dose delivered by a transdermal patch.

The Mechanics Behind Transdermal Patches

Transdermal patches have been used for many years by medical and pharmaceutical companies as an effective means of introducing elements directly into the body's bloodstream.

Apply the patch to your upper forearm or inside your wrist which are locations rich in small blood capillaries. As soon as the patch is applied, your body heat activates the the time-release function of the transdermal patch and the supplement formula begins to transit through the skin for instant and constant delivery over a 4-8 hour period.

Apply transdermal patches to arm, wrist, or stomach    
The main components that make up a transdermal patch include:
  • Liner - Protects the patch during storage. The liner is removed prior to use.
  • Formula – Supplement or medication in direct contact with release liner
  • Adhesive - Serves to adhere the components of the patch together along with adhering the patch to the skin
  • Membrane - Controls the release of the medication or supplement from the reservoir and multi-layer patches
  • Backing - Protects the patch from the outer environment

Component Parts Of Transdermal Patches

EnduroPacks transdermal amino acid patch includes 9 essential amino acids not produced internally 

Each patch contains 9 essential amino acids, including:

  • Lysine - Lysine, or L-Lysine is considered an “essential” amino acid. Our bodies cannot synthesize it, so we must get it from certain foods we eat or from a dietary supplement. Lysine is an important building block for all proteins in our bodies. It works in combination with other Amino Acids to build lean body mass and promote normal growth. Lysine also supports immune system function and a healthy cardiovascular system.
  • Leucine –  Leucine is critically important in that it is the only Amino Acid that stimulates muscle protein synthesis, so as we age it helps to slow normal age-related degradation of muscle tissue. Instead it supports muscle growth. The fact that Leucine stimulates muscle protein synthesis makes it very important to athletes, body builders, and men and women of all ages that have good exercise and, or workout routines. Leucine has also been shown to enhance and slow mental acuity due to aging.
  • Phenylalanine – Phenylalanine, or L-Phenylalanine is an electrically neutral Amino Acid and it is used to biochemically form proteins. Studies have shown that Phenylalanine helps to provide analgesic and antidepressant effects.
  • Valine – Valine, or L-Valine is classified as another “Branched-Chain” amino acid. Because Valine stimulates protein synthesis directly in muscle tissue, it is considered one of the body’s most important “fuels” used in the building of lean muscle tissue and the enhancement of muscle “reaction”. Valine also helps our bodies maintain the proper nitrogen balance. Valine also helps to stimulate the central nervous system for ongoing mental acuity and it may also improve liver functions that may have been degraded by alcohol or drug abuse.
  • Isoleucine - Isoleucine is critical to ongoing muscle tissue maintenance and it helps muscles tore glycogen to produce energy. It further helps prevent protein deterioration during muscle-demanding sports and, or exercise. It helps to repair, heal, and grow damaged muscle tissue. It also helps to reduce recovery time after workouts and, or strenuous exercise routines.
  • Methionine – Methionine, or L-Methionine is a very efficient antioxidant and it supports the natural detoxification. Methionine helps to support joint health and brain function. It also supports healthy skin and nails.
  • Threonine – Threonine, or L-Threonine is an important Amino Acid that supports many critical biological functions such as: immune system, central nervous system, liver, and cardiovascular functions. Threonine also helps to build and maintain tooth enamel and strong bones. It also speeds wound healing.
  • Tryptophan – Tryptophan is an important Amino Acid in protein biosynthesis. It has been shown to be effective for brain conditions associated with low serotonin levels, so it may have antidepressant benefits.
  • Tyrosine – Tyrosine is a critical amino acid that our cells use to synthesize proteins. There are several studies that show that Tyrosine can be beneficial during periods of colds, fatigue, and stress. Tyrosine also helps to improve cognitive and physical performance.
