Key Ingredients

Our formulas are made with clean, natural ingredients, with clinically-validated dosages to support health and performance.

Cluster Dextrin® (Highly Branched Cyclic Dextrin)

20g
Cluster Dextrin® (Highly Branched Cyclic Dextrin) is a premium carbohydrate designed to support energy, endurance, and efficient carbohydrate recovery without digestive discomfort

PeakATP (Adenosine 5’-Triphosphate Disodium)

400mg
Peak ATP® delivers functional adenosine triphosphate (ATP) to blood vessels and muscle tissue, elevating blood flow and cellular energy during exercise.

RedNite® supports systemic nitric oxide levels through a high-potency concentration of natural dietary nitrates and antioxidants.

1,500mg
RedNite® supports systemic nitric oxide levels through a high-potency concentration of natural dietary nitrates and antioxidants.

Calcium

80mg
Calcium is a crucial micronutrient that associates with mitochondria in muscle cells to stimulate ATP (energy) synthesis.

Magnesium (as Aquamin™ Mg)

50mg
Magnesium is a vital electrolyte mineral that has numerous roles in the body, one of which is regulating muscle contraction.

Sodium (as Sodium Citrate and Himalayan Rock Salt)

500mg
Sodium is the primary electrolyte in the fluid outside cells (i.e., the extracellular fluid).

Potassium (as Potassium Citrate, Potassium Chloride, and from Organic Coconut Water)

280mg
Potassium is the primary electrolyte inside cells (i.e., the intracellular space).

Organic Coconut Water Powder

500mg
Coconut water is one of Mother Nature’s most dense sources of electrolytes and trace minerals.

Cluster Dextrin® (Highly Branched Cyclic Dextrin)

20g

Cluster Dextrin is a patented form of highly branched cyclic dextrin, an atypical carbohydrate made from waxy maize amylopectin using branching enzymes that introduce extensive branching into its molecular structure. In turn, highly branched cyclic dextrin has a molecular weight of ~400,000 g/mol, far exceeding that of dextrose (180 g/mol) and maltodextrin (400-2,000 g/mol) found in most carbohydrate supplements [1].

The high molecular weight of highly branched cyclic dextrin imparts high water solubility, very low osmolality, and resistance to retrogradation. As such, Cluster Dextrin® is easier to tolerate for athletes and won’t cause the gastrointestinal discomfort of conventional sports drinks [2]. 

Numerous clinical studies have shown that athletes given highly branched cyclic dextrin pre-workout experience significantly greater peak performance capacity and reduced rates of perceived exertion (RPE) compared to those given sports beverages with dextrose/glucose or maltodextrin [3, 4]. 

Supplementing with Cluster Dextrin® after training helps replenish muscle glycogen and create a more anabolic environment for maximal recovery, especially when combined with a quality protein source like grass-fed whey isolate [5, 6].

PeakATP (Adenosine 5’-Triphosphate Disodium)

400mg

Peak ATP® is a clinically researched, patented form of disodium adenosine 5’-triphosphate structurally identical to human ATP. Using purinergic receptor signaling, Peak ATP® stimulates vasodilation and enhances calcium influx directly within working muscle cells [7].

By increasing extracellular ATP levels and muscular excitability, Peak ATP® can help promote athletic performance (e.g., peak power output) and support lean muscle hypertrophy. Peak ATP® is also a fast-acting performance booster that helps prevent fatigue and sustain work capacity during intense exertion.

RedNite® supports systemic nitric oxide levels through a high-potency concentration of natural dietary nitrates and antioxidants.

1,500mg

RedNite® is a clinically researched, highly soluble beetroot extract derived from fresh beet juice. It provides bioavailable dietary nitrates and antioxidant betalains to fuel the body’s nitrate-nitrite-nitric oxide pathway.

Through supporting nitric oxide production and optimizing muscular oxygen efficiency, beetroot extract can help promote endurance performance and lower the oxygen cost of high-intensity exercise [8].

Calcium

80mg

Calcium is an essential mineral for enhancing the integrity of bone and promoting the growth, proliferation, and differentiation of bone cells [9]. It’s also associated with mitochondria in muscle cells to stimulate ATP synthesis [10]. 

To ensure optimal efficacy and absorption, TL Hydrate features TRAACS chelated calcium and dicalcium phosphate, two highly bioavailable forms of supplemental calcium [11].

Magnesium (as Aquamin™ Mg)

50mg

Extracted from red algae, Aquamin™ is a natural source of magnesium and 72 other trace minerals. 

Aquamin® Magnesium provides magnesium in its native ionic state for optimal biocompatibility.

Consuming adequate amounts of bioavailable magnesium is imperative for active individuals to support muscle contraction during exercise [12]. 

Sodium (as Sodium Citrate and Himalayan Rock Salt)

500mg

Sodium is the primary positive ion (cation) in the fluid outside cells. It modulates the amount of water in the body, and the movement of sodium into and out of cells is essential for proper cell-to-cell signaling.

Potassium (as Potassium Citrate, Potassium Chloride, and from Organic Coconut Water)

280mg

As a counterpart to sodium, potassium is the primary cationic (positively charged) electrolyte inside cells. The balance of sodium and potassium is particularly important for cellular hydration, and potassium is necessary for intra- and intercellular signaling, as well as being a substrate for skeletal muscle contraction.

Organic Coconut Water Powder

500mg

Coconut water powder removes the sugary and fatty constituents of coconut water while retaining the essential electrolyte micronutrients, such as magnesium, potassium, phosphorus, and sodium. Due to its abundant electrolyte profile, coconut water can rapidly rehydrate athletes after intense exercise, making it ideal for pre-, intra-, and post-workout supplementation [13].

Frequently Asked Questions

Cluster Dextrin® has a high molecular weight and low osmolality, meaning it passes through the stomach rapidly. It does not pull water into the gut, so that you get carbohydrate fuel  without the bloating, cramping, or GI discomfort.

 

Yes. Endurance is formulated to work alongside TL Pre-Workout. You can use it during your session while having a pre-workout supplement. Adjust the serving size based on your session length and how much carbohydrate you need.

 

Start with 1 scoop, which provides 22 grams of carbohydrate. If your sessions run longer or your energy demands are higher, increase to 2 scoops. Mix each scoop into 10 to 12 ounces of cold water.

 

Endurance is designed for use around training. It can be used before a long session to pre-load carbohydrates and electrolytes, during exercise to sustain energy and hydration, or post-workout to support glycogen replenishment and recovery. Timing depends on your training and recovery needs.

 

Yes. Endurance is Informed Choice certified and regularly tested for banned substances, making it suitable for athletes who are subject to anti-doping rules.
