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.

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.

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.

Yes. HYK Original contains 6g of sugar, and HYK Essentials contains 5g, primarily from cane sugar. This small amount helps your body absorb electrolytes efficiently while keeping calories low.

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 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.
