Bodybuilding.com Relaunches its Private Label Brand, Signature™ Supplements

Signature™, Bodybuilding.com’s private label line, is back and better than ever. The line originally debuted in 2018 but enters the year with new formulas, the omission of artificial dyes and coloring, and an increased sourcing standard. Touting a whopping 45 skus and over six new products, Bodybuilding.com has set its sights on delivering Signature™ to millions of gym goers and fitness enthusiasts in 2025.

The line covers pre, intra and post workout nutrition, as well as key products geared towards muscle building, weight loss and general health goals. From whey and plant proteins to EAA and greens, Signature™is geared for any goal.

“Our Bodybuilding.com Signature™ Series sets the benchmark for innovation and quality,” said Steve Marada, Head of Product Development for Bodybuilding.com. “Every  product we develop is backed by cutting-edge science, from new ingredient forms to  enhanced flavors, all produced by U.S.-based manufacturers adhering to the highest  standards, including GMP-certified practices. Our mission is to push the boundaries of  what’s possible in sports nutrition without ever compromising on quality or safety. When you choose Signature™, you’re choosing unparalleled excellence.”

The line features four core categories to help consumers reach their health and fitness goals.

Building Bigger Muscle 

True to the history of BBCOM, the line leads with its top performers – proteins and creatine. It also releases L-Glutamine and a testosterone booster.

The line’s most sought out supplement, Signature™️ 100% Whey Protein is back by popular demand in classic flavors like chocolate and vanilla in addition to a new favorite, cinnamon cereal. Each scoop has 25 grams of protein, 2 grams of carbohydrates, and 1 gram of fat as  well as 11.9g of essential amino acids (EAAs) and 5.5g of branched chain amino acids  (BCAAs). The powder contains digestive enzymes to help break down and absorb protein more efficiently.

Signature™️ also brings a 100% Isolate. With 25 grams of pure whey protein isolate, it’s  filtered to remove the majority of the lactose, fat and carbs, making it higher in protein, leaner, and faster digesting than standard whey protein. Its quick release of amino acids is ideal for supporting post-workout muscle growth and recovery.

New to Signature™️ and marking the first ever in BBCOM’s private label history, a plant protein makes its debut in chocolate and vanilla. Signature™️ Plant Protein combines a  powerful blend of pea, rice, and fava beans, delivering a solid 25 grams of high-quality  plant-based protein in every serving. Designed to support muscle growth, recovery, and  daily nutrition, this complete protein blend provides all essential amino acids without any dairy.

Creatine Monohydrate, arguably the most studied supplement on the market, remains in line as the demand for creatine booms across demographics and age groups. Historically  known for its muscle building properties, today’s research is also showing promising  results on longevity and cognitive health. Signature™️ Creatine comes with a 200-mesh rating.

Fueling Workouts and Performance: 

No stranger to propelling performance, Bodybuilding.com debuts a new electrolyte powder, EAAs, and caffeine capsules while returning BCAAs and pre-workout.

Bodybuilding.com’s Signature™️ electrolytes formula delivers a well-balanced blend of  sodium, potassium, magnesium, and calcium to support peak muscular performance, muscle contractions, and hydration. It contains 5.4 grams of electrolytes per serving including 900mg of potassium, 680mg sodium,100mg calcium, and 50mg magnesium to help you stay hydrated before, during, and after workouts.

Signature™️ EAA supplement offers a proven formulation to help build more muscle, recover faster, and help maintain hydration. In a single 10g serving, one gets 5.2g of BCAAs  at a 2:1:1 ratio of leucine, isoleucine, and valine; plus, histidine, methionine, phenylalanine, threonine, and tryptophan; as well as electrolytes: sodium, potassium,  magnesium, and calcium.

While EAAs offer more complete support for muscle building, Signature™️ BCAAs are a  highly effective, affordable option for consumers looking to support their training goals.

BCAAs are rapidly absorbed, making them perfect for quick intra-workout support, especially when focusing on muscle preservation and immediate energy during training.

Signature™️ Caffeine capsules feature 100% coffea robusta extract which is designed for sports-minded individuals who seek a powerful energy boost. With a medium dose of 200  mg of natural caffeine, it can help enhance energy levels, focus, and performance. Coffea robusta offers a stronger caffeine concentration than its Arabica counterpart, with a  sustainable, eco-friendly cultivation process that supports both environmental and personal wellness. This product is ideal for athletes who want to amplify their training with a naturally sourced, sustainable energy boost.

Signature™️ Pre-Workout contains proven ingredients to help with muscle growth, energy  production, muscular endurance, blood flow, mental focus, and hydration. The biggest  reason to take Signature™️ Pre over other pre-workouts is that it contains L-leucine, which  has shown to greatly increase muscle mass, help with fat loss, and prevent muscular  fatigue.

Shredding Fat: 

With a $4.6B weight loss market in the U.S., consumers are struggling to lose weight. Bodybuilding.com stands by the notion that the right workout and nutrition plan can help  users tackle stubborn fat, along with a supporting supplement stack. In fact, the brand  debuted a new fitness app in early 2025, aimed at helping users build muscle, lose fat and  become more athletic. New users can unlock a $49.99 product voucher with annual  membership sign up along with year-round free shipping and 10% off all Signature™️ supps.

Signature™️ Shred, a new product and formula for BBCOM, contains a blend of CLA, Garcinia, and CaloriBurn GP while providing sustained energy, enhanced fat metabolism,  and optimal calorie expenditure. With its range of scientifically supported benefits, this powder supports those on a journey to shed fat, improve muscle retention, and achieve a  balanced, lean body composition.

Bodybuilding.com Signature™️ Diuretic can be a safe and effective way for anyone looking to reduce bloating, increase metabolism, or simply burn more fat during workouts. With the majority of its ingredients coming from natural sources, one can have peace of mind about adding this supplement into their stack.

For those seeking a supplement to help with cravings or regulating blood sugar and insulin  sensitivity, this is it. The Signature™️ Appetite Control formulation contains natural  ingredients that help boost metabolism, lower fasted glucose levels, make sugary food less appealing, block carb absorption, and increase satiety through serotonin increase.
