Japanese-made endurance nutrition for athletes racing in Malaysian conditions. As Stamina Sports (Malaysia), we bring you Katsuo Stamina, our flagship supplement made in Japan using Migratory Fish Extract (hydrolysed katsuo/bonito peptide). Alongside it, QC Stamina provides protein during very long events, and ELEC Stamina electrolyte tablets help replace the sodium you lose in heat and humidity. Carbohydrate, fluid and pacing come first in any race plan. We will tell you where our products fit, and where they do not.

Japanese Sports Science Behind Every Katsuo Stamina Formula

Katsuo Stamina is developed in Japan, drawing on Japanese sports nutrition research to support athletes who push their limits. As Stamina Sports (Malaysia), we bring this formulation to marathon runners, triathletes and endurance athletes across Malaysia. Katsuo Stamina was previously certified under the Informed-Sport and Informed-Choice programmes; that certification has lapsed and we are working to restore it.

Electrolyte Tablets & Long-Duration Protein for Endurance Athletes

Fuelling and hydrating over long distances in heat is one of the biggest challenges for runners and cyclists. Here is the job each product in the range is designed to do:

• Katsuo Stamina — a Japan-made pre-race option using Migratory Fish Extract. An unusual ingredient, so we set out what the research does and does not show.
• QC Stamina — protein for very long events, relevant once your carbohydrate intake is already covered.
• ELEC Stamina — electrolytes plus B1/B2 to help replace sodium lost through sweat over long, hot efforts. Cramping has several causes, and electrolytes are not a cure for it.

Used by Marathon, Ultra-Trail & Triathlon Athletes Across Malaysia

We work with everyday runners, ultra-trail racers, triathletes and weekend warriors preparing for races in year-round heat and humidity. Whether you are training for a marathon, a long trail event, or simply building weekly volume, we would rather help you get the basics right first, then show you where KATSUO, QC and ELEC genuinely fit into your own race plan.
