      American GAINZ Introduces "CORE"!

      American GAINZ Introduces "CORE"!

      At American GAINZ Nutrition we rely heavily on the fitness community to shape the direction of our performance nutrition offerings.  THANK YOU to all of our supporting athletes from around the country!  Your input is incredibly valuable and led to the development of our latest creation - American Gainz CORE!  

      We have listened, sourced, and created a product we are stoked to launch as we welcome in the 2018 competition season.

      After overwhelming success during the last stages of sensory testing, we are excited to share the basis of the “AGN Core” design with our community as we prepare for launch!

      Performance Nutrition
      • 25 Grams Protein from Whey
      • > 5 grams of naturally occurring BCAAs

      Organic & Natural Ingredients
      • Nothing Unnecessary – Protein, Flavor, & Sweetener
      • Pasture-fed Premium Whey, Organic Coconut Sugar, Organic Cocoa, Sea Salt
      • The cleaner the ingredients, the cleaner the taste, the better the product…FACT

      Quantity & Package
      • 2 ½ lbs.  –  ½ lb more protein than the typical 2 lb. quantity
      • Same durable material and gym bag compatible stand-up pouch

      • We simply added Organic Cocoa, so naturally, that’s what it tastes like!
      • Sea Salt - yes, a pinch of sea salt was added after the second sensory trial to smooth out the raw silhouette of cocoa
      • It's Light - yes, if you love liquid brownies, this isn't for you.  Think of it like this; If the typical GNC dessert powder is orange juice, Core Protein is like Orange sparkling water.  It's light, fluffy, many sweet tooth consumers add a small serving of their favorite organic sweetener :) 

      *Important - Directions for Use
      Core Only requires 2 scoops per serving and ONLY 8 Ounces of water; due to the organic nature of the product's flavor, too much water can easily water down the flavor quickly.

      8 Ounces is no more than a cup of coffee for reference. On a classic blender bottle shaker, the 8 fl oz marker is ONLY a third of the way up a shaker bottle as depicted!




      Balanced Sweetener
      • Organic Coconut Sugar - Fastest growing natural sweetener sourced in the U.S.
      • Reformulation process for the new and improved Tactical Recovery is taking place now!
      • AGN Core is just sweet enough to balance the natural bitterness of cocoa

      USADA & WADA & FDA & Lab Testing
      • Although the USADA does not certify, endorse, or approve supplements, Core is NOT a supplement. It’s protein from milk with all natural ingredients.
      • Categorized by the FDA, AGN Core is considered a conventional “food” product
      • American Gainz Nutrition guarantees our products do not contain any ingredients on the WADA prohibited list.
      • 3rd Party Lab Results for all products will be posted to the website before the new year!

      If you have any questions or ideas for future products, please feel free to email us

      Stevia or Sucralose to Sweeten Your Whey Protein…

      Stevia or Sucralose to Sweeten Your Whey Protein…

      clean sugars: stevia vs sucralose in whey protein powderThe word "clean" appears a lot in conversations surrounding protein. Clean can mean a lean ingredient list, no chemicals, no fats, no heavy metals, minimal cholesterol, no fillers, or even Made in the USA. Sometimes "clean" refers to no sugars. It is important for you to understand what is sweetening your daily protein supplement when it does not contain sugar.

      The Backstory

      As the health and wellness boom sweeps across the globe, athletes in particular are beginning to pay more attention when exploring new supplements or proteins. If you are focused on making gains and consuming a protein powder without consuming tons of unnecessary calories, your natural tendency may be to stay away from simple sugars (i.e., fructose, sucrose, and lactose).  Let's be clear, our market is the fitness community.  We don't believe sugar in moderation is bad, and as a matter of fact our latest product launches "Core" and "Tactical Recovery" both contain Organic Coconut Sugar (comparable to 2 apple slices) in place of a artificial sweeteners. 

      Despite the FDA regulations on nutrition facts panels (NFPs), many protein brands forgo disclosing that their product contains “simple sugars," especially in the form of lactose*. These same brands display warning statements in bold that read, “If you are Lactose Intolerant do not use this product." By putting two and two together, you can begin to understand these common practices in nondisclosure. The NFP does not list sugar; yet, the manufacturer warns the consumer that the product is loaded with lactose. Another way to determine when sugar is not disclosed on the NFP is to look at the number of carbohydrates in grams and subtract everything else in the sub-heading (for example, fiber). The remainder can indicate the undisclosed sugar. Keep in mind, "Supplement Facts" are designed to look like a traditional regulated NFP, but below is a good example of why we suggest to stay away any protein products that are classified as "Dietary Supplements".

      *Lactose is a milk sugar (made up of glucose and galactose units) that remains along with the whey protein once water is removed in the process of creating whey protein concentrate (WPC) from wet whey.


      examples of Nutrition Facts disclosing and non-disclosing sugars


      Not disclosing the sugar content is one thing, but listing 0 grams of sugar is where the need for sugar alternatives comes into play, especially when talking about whey protein isolate (WPI) or whey protein hydrolysate (WPH), which each contain minimal natural sugar (lactose) when compared to whey protein concentrate (WPC). The most common sweeteners to compensate for the lack of lactose are sucralose or stevia.

      What is Sucralose?

      Sucralose is the only type of artificial sweetener derived from real sugar molecules. It is created by substituting one part of a sugar molecule with chlorine to create a substance that is about 600 times sweeter than sucrose; this is why so little is needed to sweeten even the most bitter protein powders. This is great because when talking about clean and lean protein powders, a protein utilizing sucralose essentially has 0 grams of the daily serving attributed to the sweetener, which leaves each serving loaded with what the consumer wants and is paying for — protein. Sucralose also differs from other artificial sweeteners in that it passes through the digestive system without being metabolized, which is why it contains no calories. It is made right here in the USA. The taste profile is immediate, and in your face sweet, it's often used to mask undesired flavors by tying the pallet up with intense sweetness. 

      What is Stevia?

      Stevia is obtained from an herb known as yerba dulce, which is grown in Paraguay, Brazil, Southeast Asia and other places (tropical climates, not made in the USA). When stevia was first introduced to the U.S. market, it was only available as a dietary supplement but quickly gained popularity as it can be marketed as "Natural". Stevia contains different chemical compounds that make it sweet, including its principal sweetening agent, rebaudioside A. These compounds make stevia anywhere from 40-300 times sweeter than table sugar. Thus, one teaspoon of stevia extract has about the same sweetening potency as an entire cup of sugar.

      Are they FDA approved Sweeteners?


      Yes. Sucralose has an excellent safety profile. More than 100 safety studies, representing over 20 years of research, have shown sucralose to be safe. Sucralose was FDA approved as an all-purpose sweetener in 1998 in the USA, and further recognized and approved by numerous global FDA equivalents:

      • European Union Scientific Committee on Food (SCF)
      • Food Standards Australia/New Zealand (FSANZ)
      • Health Protection Branch of Health and Welfare Canada
      • (Food and Agriculture Organization/World Health Organization) Joint Expert Committee on Food Additives (JECFA)
      • Japan’s Ministry of Health and Welfare


      In the United States, high-purity stevia glycoside extracts are generally recognized as safe (GRAS) and are allowed as non-nutritive ingredients in food products without a formal "approval".  GRAS is different than "approved by the FDA".  The FDA has simply put, not questioned the GRAS notice of stevia glycosides as a high intensity sweetener.  So unlike Sucralose, Stevia does not have "Approved" status as food additive.

      In more detail, these stevia glycocides are what can be found sweetening many protein powders.  This said, its important to know, both stevia leaf and crude extracts do not have GRAS notices or Food and Drug Administration (FDA) approval for use in food.  To see how these glycosides are extracted here is the best video we found. Link to Real Stevia Extraction process (American Gainz Nutrition Disclaimer - We had zero choice in the music selection on this video, lol). 

      Although stevia is assumed safe by many due to its status as a natural sweetener, the Center for Science in the Public Interest (CSPI) notes that being natural does not guarantee safety. Both Canadian and U.S. regulatory agencies have rejected stevia in the past. In addition, a European Community scientific panel made the decision that stevia was not an acceptable food additive. 

      The Take-Away

      If you are the type of health-conscious athlete who relies on nutrition in order to achieve peak performance, at American GAINZ Nutrition we strongly recommend always going with a lean & clean protein powder with minimal ingredients regardless of your preference of sweetener, as long as you understand all the ingredients and they are all openly disclosed on the packaging.  We encourage you to avoid the calories from excess simple sugars and any brands that do not disclose their sugars in the nutritional fact or supplement fact panels. Our latest launch of both "Core" & "Tactical Recovery" proteins utilizes the latest and greatest FDA Nutrition Facts Panel which fully discloses "Added Sugars" as a component of the total sugar.  If you prefer a pure, unflavored option, check out The Best Grass-Fed Whey, no sweeteners at all, just the worlds best certified Grass-fed Whey.

      Ingredients vs. Claims Vol. 2: Casein

      Ingredients vs. Claims Vol. 2:  Casein

      Ingredients vs. Claims Vol. 2: Casein
      Written by American Gainz Nutrition

      At American Gainz Nutrition, we believe Casein proteins are the keystones to achieving GAINZ, and thus created a short Q&A to best share the information.


      1.  What is the role Casein plays in milk’s nutritional value?

      A two-month old calf will drink an average of eight liters of milk per day.   In less than 15 months, this cow will tip the scale at ~ 2,400 lbs. Likewise, a human baby will have tripled his/her body weight in the first six months just by drinking milk. So the purpose of milk seems clear - growth & development.

      But what is it about milk that promotes this type of growth? Most athletes are under the impression that the whey protein in milk is what contributes to growth, when in fact, cow milk protein is nearly 80% Casein and only 20% Whey. The majority of Gainz from milk comes from casein protein.  

      2.  Why aren’t there more Casein Protein powders marketed to Athletes?

      The easiest answer is money. It costs more. Extracting Micellar Casein protein can only occur at the sacrifice of the cheese making process as it involves extracting protein directly from the milk. Whey protein, on the other hand, is separated from the curds and drained as part of the cheese manufacturing process, leaving the cheese unaffected. It’s often described as a byproduct of cheese manufacturing.

      Whey protein is also naturally sweeter. This is because the lactose (simple sugar) stays with the whey when it is separated from the curds which explains why it is very difficult to find a whey protein concentrate that does not contain lactose and Casein is often labeled as 100% lactose free.

      3.  Why is Casein considered a slower digesting protein relative to whey?

      Casein is incredibly sticky. It is slower digesting because of its gel forming properties, which literally slows down intestinal motility.  Casein protein is also highly digestible relative to whey protein. This is why whey protein can sometimes stimulate a localized intestinal response often attributed to “milk allergies” when really, it’s due to an inability of a portion of the protein to be broken down.

      As performance athletes, we need slow amino acid release as numerous studies have proven this pattern to be the most powerful at promoting an anti-catabolic environment for muscle growth. The fact is, you grow and recover the most while sleeping.

      4.  What does “Micellar” mean when referring to Casein?

      Micellar casein refers to the molecular structure of the protein being intact and therefore containing the peptides in their natural form (undenatured). To retain an abundance of micellar protein during processing, a specialized treatment of the milk has to be performed which sacrifices the ability to make cheese, thereby making the process very expensive.

      Because the casein micelle is in suspension, it can be separated from the rest of the milk through centrifugation at a very high speed. Utilizing ultrafiltration or microfiltration along with avoiding exposure to heat, acid or other chemicals, the micellar casein structure will remain intact. Thus, more bioactive peptides, with immuno- and growth-modulating effects, are present in the protein. Gainz!!!

      5.  What is the general process difference for Whey Protein vs. Micellar Casein Protein?


      1. Milk – Collected from cows
      2. Standardization – The milk is pasteurized
      3. Culture & Coagulant – Bacteria used to trigger coagulation
      4. Cutting – Liquid whey & curds are separated
      5. Whey Draining – Whey is drained, leaving the solids behind called curds
      6. Whey is dehydrated and considered WPC (Whey protein concentrate) 20% Fat & Lactose

      Micellar Casein (undenatured)

      1. Milk – Collected from cows
      2. Standardization – The milk is pasteurized
      3. Centrifugation – The intact Casein Micellar structures are extracted and dehydrated

      In closing, both casein and whey proteins, if utilized correctly, are an amazing performance combo added to any fitness regime - whey to spike the blood with instant amino acids and casein to keep the BCAAs flowing!!!

      Ingredients vs. Claims Vol. 1: “Lactate” - Written by American Gainz Nutrition

      Ingredients vs. Claims Vol. 1: “Lactate” - Written by American Gainz Nutrition

      Ingredients vs. Claims Vol. 1: “Lactate”
      Written by American Gainz Nutrition
      Contributor: Rodrigo Salas, M.D. CFL1


      Ever wonder what the hype over “lactate” based energy supplements is all about?

      Products containing “lactate” are becoming increasingly popular and many specifically target the box community with extremely attractive claims:

      Increase work capacity | Reduce muscle fatigue | Increase endurance | Increase recovery speed |Reduce Lactic Acid | Improve Aerobic Threshold |Reduce Muscle Soreness

      Well due to the recent flood of emails we’ve been receiving with inquiries around these specific claims, we thought we would just put this information out there, and then leave it up to you to experiment and let us know. Specifically we are talking about powdered pre-workout or energy supplements that contain Calcium Carbonate, Calcium Lactate, Magnesium Lactate, or a combination of all three.  

      For those who do not have a full awareness of lactates role in the body, we did our best to cover it at a high level, unfortunately biochemistry is a bit unforgiving when over simplified. So here it goes:

      Of the 3 energy systems, it’s the Anaerobic Pathway where “lactate” comes into play.

      Unlike the ATP-Phosphocreatine System (PC) which utilizes high energy phosphates stored within the muscle tissue, the Aerobic and Lactic Acid (Anaerobic) pathways rely on a different mechanism to produce energy. They both need a chemical substrate that has to be cleaved in subsequent reactions to provide the cell with its main energy currency, ATP. The most used chemical substrate in the tissues is Glucose, whether it is coming from regular diet or intrinsic metabolic pathways such as glycogenolysis or gluconeogenesis, it is the downstream cascade of reactions that are to be taken in account to objectively evaluate abovementioned claims.

      It’s important to note, although both the PC and Lactic Acid systems are considered anaerobic, they are not part of the same type of performance (mechanical work). PC is responsible for the explosive, fast twitch contractions 0-10 seconds, 1 RM, or 40 yard dash type of work. Whereas the Lactic Acid system is responsible for your performance during an intense 10-30 second exercise range, limited by the energy output of this pathway and the chemical properties of lactate (lactate acid) that’s proven to interfere with cellular homeostasis.  

      Each glucose molecule entering a cell during an energy demanding state goes through a process called Glycolysis, where they are cleaved by several enzymatic reactions to synthesize “Pyruvate”. This fact is why “Pyruvate” and more specifically “Creatine Pyruvate” can be found in several popular pre-workouts. This molecule with energetic potential has two downstream options that rely on the presence or absence of Oxygen, hence aerobic and anaerobic pathways. The difference between both pathways is that the aerobic goes through a secondary phase called Kreb’s Cycle, providing with 32 ATP per glucose molecule overall, while the anaerobic goes directly to lactate and provides only 2 ATP per glucose molecule.

      This “lactate” moves passively out of the muscle cell membranes to the bloodstream and heads to the liver to be metabolized. This process is called “Cori Cycle”. In this cycle, lactate is reconverted to glucose by liver cells by a process called gluconeogenesis (new synthesis of glucose), but this reaction requires energy. As lactate produces 2 ATP in the muscle tissue, it uses 6 ATP in liver cells, giving a total output of negative 4 ATP, so this high energy demanding metabolic process by itself is not efficient in overall performance.

      The abovementioned fact is the main argument of why lactate intake would not be the most efficient supplementation to increase performance. Since you are already taking the molecule “lactate”, the muscle tissue is not creating the 2 ATP that would be produced during anaerobic glycolysis, and is also depleting the liver of 6 total ATP for each 2 lactate molecules that are being converted to 1 Glucose and sent to the muscle tissue latter on. This process, by quantifiable fact, is not very efficient.  

      Moreover, lactate by itself, regardless of ATP production, has chemical properties that can alter normal molecular behavior. Lactate is an acid, meaning that it can decrease the pH of its surrounding environment, and as the cell is exposed to unnatural conditions, some enzymes that are in charge of glycogen breakdown stop working properly. Acidity will interfere with calcium binding to troponin preventing efficient contractile force. Continuous exposure to an acid environment will deplete cells from potassium, originating an electrolyte imbalance within the muscle cell, hence, subnormal muscle response - “the burn”.


      There is some scientific literature that supports that lactate intake can increase performance, but the majority lack proper biochemistry support. Also, their sample sizes are not big enough to give a statistically significant conclusion. Of the studies available, the stated hypotheses do not include all of the surrounding implications. However, as the possibility of these claims to be true should not be ruled out entirely, there are no current studies that properly support them.

      So before you drop $50 on magic engine powder containing the same ingredients found in TUMS (Calcium Carbonate), please note that ingesting “Calcium Carbonate” or “Lactates” is not currently a scientifically accepted practice that can produce these abundant performance enhancing claims.
