Engineered Nutrition: zero-sugar electrolyte mix for athletes

Engineered Nutrition is a sports supplement brand that sells a zero-sugar powdered electrolyte mix, presented as a complete hydration formula for those who train or need to maintain fluid balance throughout the day. The company targets runners, CrossFit athletes, cyclists, weightlifters and active professionals, and distributes its product mainly through its online store.

The formula and its electrolyte ratio

The product is built around what the company calls the "Golden Hydration Ratio": an electrolyte ratio designed to replicate the way the body loses them through sweat. The formula includes eight dosed components, each with its stated function:

• Sodium: 600 mg (26% DV), aimed at replenishing the loss from an hour of intense training.
• Chloride: 690 mg (30% DV), in a 1:1 ratio with sodium to promote water absorption.
• Potassium: 188 mg (4% DV), associated with the muscle contraction and relaxation cycle.
• Magnesium: 34 mg (8% DV), a cofactor in more than 300 enzymatic reactions, including ATP production.
• Calcium: 52 mg (4% DV), combined with magnesium in a 2:1 ratio for absorption.
• Zinc: 10 mg (90% DV), linked to the immune system and tissue repair.
• Vitamin B6: 3.4 mg (200% DV), related to protein metabolism and neurotransmitter production.
• Vitamin B12: 5 mcg (210% DV), involved in red blood cell formation.

The company states that the product contains no sugar, carbohydrates or calories and is sweetened with stevia. The mix comes in individual stick packs, designed to be carried in a pocket, gym bag or carry-on, with no need for containers or measuring scoops.

Certification and stated guarantees

Engineered Nutrition notes that its product is Informed Sport certified, with batch testing in laboratories accredited under ISO 17025. The company also declares a 30-day money-back guarantee for all orders and offers free shipping on orders over $50, with an average delivery time of three days. According to its own presentation, the mix is made and packaged in the United States.

Available flavors

The store catalog shows five flavors: lemonade, peach mango, mixed berries, pineapple and tamarind.

Customer profile and reviews

The company collects testimonials from users including CrossFit athletes, marathon runners, cyclists, weightlifters and professionals with regular physical activity. Among the featured comments are those from Christine Middleton, an athlete with six CrossFit Games appearances, and other customers who mention the absence of sugar, reduced cramping and improved recovery. The website shows an average rating of 4.81 out of 5 based on 358 reviews, and another section indicates 4.80 out of 5 with 405 verified reviews. The company also publishes the results of its own 14-day survey of users, in which 96% said they felt more hydrated throughout the day, 83% reported faster recovery between sessions, 74% sharper mental focus and 79% steadier energy without crashes. The company itself notes that these are self-reported results and may vary between individuals.

Adaptation timelines according to the company

Engineered Nutrition describes on its website a performance-oriented progression: in the first few days, the formula aims for initial hydration and faster fluid absorption; during the first week, it targets greater training stability and fewer cramps; between the second and third week, improved recovery and less stiffness; and by the fourth week, full system adaptation, with better sleep and greater endurance. The company presents this sequence as part of its product proposition and not as a guaranteed result.
