HYK (pronounced "hike") is a hydration brand built for endurance athletes. We pride ourselves on providing science-backed products with ingredients in the correct doses to support energy, focus, hydration, and recovery, helping athletes perform at their best. Learn more about the science behind HYK ingredients.

HYK Original is an all-in-one endurance formula with electrolytes, energy, focus, and recovery ingredients. HYK Essentials is a streamlined electrolyte mix for daily hydration with our Advanced Absorption Formula.

Absolutely — HYK Original is specifically formulated for ultra runners and endurance athletes who demand more than basic hydration. It’s an all-in-one formula that delivers energy, focus, hydration, and recovery support in a single drink, helping you perform at your best over long, intense efforts. Unlike other products on the market, HYK is designed for the unique needs of marathons, ultramarathons, trail runs, and other extended endurance challenges, giving you the fuel and support you need to push further, recover faster, and stay sharp mile after mile.

For longer runs or multi-stage events, HYK Essentials is the perfect complement. While HYK Original powers your energy, focus, hydration, and recovery, Essentials provides clean, everyday electrolyte support to help you maintain optimal hydration and stay steady throughout the remainder of your run or event — keeping you performing at your best from start to finish.

HYK can be used before, during, or after workouts depending on your goals. HYK Original is designed for endurance and performance, so it’s best used during intense activity. Original can be consumed up to 30 minutes prior to activity to begin feeling the energy and focus needed for the event. HYK Essentials is perfect for hydration anytime, including before or after exercise.

No. We pride ourselves on transparent labeling with no hidden ingredients, no proprietary blends, and no artificial fillers.

No, not exactly — your body can absorb electrolytes without sugar. However, small amounts of glucose can help enhance absorption, particularly for sodium and water, by supporting more efficient transport in the gut. That’s why HYK includes a targeted amount of cane sugar — not for sweetness, but to help optimize hydration and support performance for endurance runners and trail athletes without unnecessary excess.

Electrolytes alone don’t prevent bonking, but they play an important role in helping you stay properly hydrated, maintain muscle function, and avoid early fatigue. HYK Original goes a step further by combining hydration, energy, and focus-supporting ingredients in one formula — helping you stay sharp, maintain output, and avoid the kind of drop-off that leads to bonking during long efforts.

Electrolytes should be taken before, during, and after runs, depending on distance and intensity. For shorter runs, pre-hydration may be enough. For longer runs, trail runs, or endurance sessions, taking electrolytes during your run helps replace what you lose through sweat — especially sodium, potassium, magnesium, and calcium. HYK products are designed to support all phases of your run, from preparation to recovery.

During one hour of intense endurance exercise, athletes can lose a significant amount of electrolytes through sweat, which are crucial for muscle function, nerve signaling, and hydration balance:

• Sodium: 800 – 1,200 mg per hour (can vary based on sweat rate and climate)
• Potassium: 200–400 mg per hour
• Magnesium: 20–60 mg per hour
• Calcium: 10–30 mg per hour

These losses depend on factors like temperature, humidity, sweat rate, and individual physiology. If these electrolytes aren’t replenished, athletes may experience muscle cramps, fatigue, impaired focus, and slower recovery. HYK is formulated to replace these key electrolytes in scientifically supported ratios, using pure sea salt, potassium, and magnesium, ensuring you maintain hydration and performance during long or intense workouts.

Yes. All HYK products are formulated with ingredients that are safe for competitive athletes. None of the ingredients in our products appear on the World Anti-Doping Agency (WADA) list of prohibited substances, which is the global standard for banned performance-enhancing substances in sports.

HYK is a strong alternative to LMNT for athletes who want more than just sodium-heavy hydration. While LMNT focuses primarily on electrolytes, HYK Original is designed for endurance athletes, delivering a balanced blend of electrolytes, energy, focus, and recovery support in one formula. If you’re running long distances or training hard, HYK provides a more complete fueling strategy.

HYK offers a more performance-focused alternative to Liquid I.V. While Liquid I.V. is widely used for general hydration, HYK is specifically built for runners, trail athletes, and endurance training, with a focus on electrolyte balance, sustained energy, and ingredient transparency — no unnecessary fillers or hidden blends.

HYK is a premium alternative to Instant Hydration for athletes who want fully transparent, purpose-driven formulas. Instead of basic hydration, HYK Original is formulated to support endurance performance, helping you stay hydrated, energized, and focused during longer efforts.

HYK is committed to premium quality and safety. All of our products are manufactured in a cGMP-certified facility, which stands for current Good Manufacturing Practices. This means the facility follows strict guidelines for ingredient sourcing, production, packaging, and quality control, ensuring every batch meets the highest standards.

In addition, our products are tested by SGS, a globally recognized independent quality and safety testing organization. SGS verifies that our ingredients are accurately labeled, free from contaminants, and meet strict purity standards. This combination of cGMP manufacturing and SGS testing ensures that every packet of HYK you use is safe, reliable, and effective, giving athletes confidence in their hydration and performance support.

Sea salt contains trace minerals naturally lost in sweat and is free from the additives and anti-caking agents found in table salt. This makes it ideal for optimal hydration and mineral replenishment.

HYK Essentials contains no caffeine or stimulants. HYK Original contains 120mg of caffeine from green tea leaves, providing calm, sustained energy. No other stimulants are included in our formulas.
