Rapid Rehydration

Promote Muscle Recovery

Transparent Labs Hydrate Black includes adaptogens and taurine to support recovery after physical activity.

Promote Muscle Recovery

Energy Support

Enhances focus, alertness, and aids in providing clean energy to keep you performing at your best

Energy Support

Enhance Exercise Performance

Adequate hydration lays the foundation for athletes to perform at their best, whether engaging in high-intensity exercise or endurance sessions.

Enhance Exercise Performance

Key Ingredients

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

SenActiv™

50 mg

SenActiv® is a patented adaptogenic complex that helps accelerate muscle recovery during/after strenuous exercise.

SenActiv™

Taurine

1,000 mg

Taurine is a sulfur-containing amino acid with numerous performance enhancing properties

Taurine

PurCaf®

100 mg

PurCaf® provides natural caffeine from organic green coffee beans to enhance stamina and delay fatigue.

PurCaf®

Calcium (as TRAACS® Calcium Bisglycinate and Di-Calcium Phosphate)

84 mg

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

Calcium (as TRAACS® Calcium Bisglycinate and Di-Calcium Phosphate)

SenActiv™

50 mg

SenActiv® is a patented, clinically studied ergogenic adaptogen complex that provides highly purified and fractionated extracts of Panax notoginseng and Rosa roxburghii (rose hips).

 The unique phytochemicals in SenActiv® have been shown to enhance cellular processes that accelerate muscle recovery after exhaustive exercise [1]. 

These compounds also possess adaptogenic properties to facilitate athletic performance and healthy aging [2].

SenActiv™

Taurine

1,000 mg

Taurine is a naturally occurring amino acid not abundant in the diet. One of the primary benefits of taurine is its role in enhancing exercise capacity through influencing calcium dynamics in muscle cells. Taurine facilitates calcium release necessary for muscle contractions. [3

Transparent Labs Hydrate Black includes a clinically-validated dose of taurine to improve exercise performance and support recovery. Clinical studies  show that taurine supplementation can enhance anaerobic performance, increase time to exhaustion, and reduce oxidative stress.  [3, 4]

Taurine

PurCaf®

100 mg

On the molecular level, caffeine (chemically known as 1,3,7-trimethylxanthine) is an alkaline, organic substance derived from xanthine — a biologically important purine base found in many bodily tissues and fluids. 

Methylxanthines like caffeine and theobromine stimulate the central nervous system (CNS) and heart to promote wakefulness and motivation.

Numerous studies have shown that taking caffeine before exercise can significantly improve overall performance, largely by reducing the rate of perceived exertion [5]. Caffeine may also enhance endurance and strength by increasing fatty acid oxidation and sparing muscle glycogen [6].

PurCaf®

Calcium (as TRAACS® Calcium Bisglycinate and Di-Calcium Phosphate)

84 mg

Calcium is an essential mineral for enhancing the integrity of bone and promoting the growth, proliferation, and differentiation of bone cells [7]. It’s also associated with mitochondria in muscle cells to stimulate ATP synthesis [8]. 

To ensure optimal efficacy and absorption, TL Hydrate Black features TRAACS chelated calcium and dicalcium phosphate, two highly bioavailable forms of supplemental calcium [9].

Calcium (as TRAACS® Calcium Bisglycinate and Di-Calcium Phosphate)

Magnesium (as Aquamin™ Mg)

50 mg

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 [10]. 

Magnesium (as Aquamin™ Mg)

Sodium (as Sodium Citrate and Himalayan Rock Salt)

1000 mg

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.

Sodium (as Sodium Citrate and Himalayan Rock Salt)

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

250 mg

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.

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

Organic Coconut Water Powder

500 mg

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 [11].

Frequently Asked
Questions

How is Hydrate Black different from Classic Hydrate?

Both formulas share electrolytes, taurine, coconut water powder, and Senactiv®. Hydrate Black is “supercharged” with 100 mg of natural caffeine and double the sodium (1000 mg vs. 500 mg)—ideal for high-intensity workouts or for endurance athletes needing more electrolyte replacement.

Is Hydrate Black right for everyone?

Hydrate Black is best for those who want added caffeine and higher sodium content. If you want a caffeine-free daily hydration formula, Transparent Labs classic Hydrate may be the better choice.

Is it tested for banned substances?

Yes, Hydrate Black (like Classic Hydrate) is Informed-Choice® certified.

When should I take it?

Mix 1 stick with 10–12 oz cold water before, during, or after exercise. Use 1–2 servings daily depending on training and hydration needs.

How Do You Tell if Your Electrolytes are Low?

Signs of low electrolytes include muscle cramps, fatigue, dizziness, headaches, and dehydration. If you’re sweating heavily, feeling weak, or experiencing irregular heartbeats, your body might be lacking key minerals like sodium, potassium, and magnesium. Stay ahead by hydrating and replenishing electrolytes as necessary.
