Proprietary blends
The KORE fuel standard

Formulated the way sports science actually reads.

We don't chase trends. We chase peer-reviewed dose ranges, verified sourcing, and honest labels. Every serving hits the number that clinical research suggests, not the number that looks good on the front of a bag.

“Half the industry hides behind proprietary blends. KORE just prints the mg — that alone made me switch.”

Finally, electrolytes without the sugar dump.

I've tried them all. The Citrus sticks are the first hydration mix that actually feels like the ratios I need on a 20-miler. No stomach hit, no crash, no candy taste.

Daily Electrolytes

The recovery formula that finally kept me asleep.

Between the casein and magnesium glycinate, my sleep score jumped almost overnight. Deloads used to wreck me — this took a full week of soreness off.

Night Recovery

Clean stim, no jitters, hits at mile 3.

The Sharp Pre-Workout doesn't feel theatrical. It just kicks in around the second mile and stays even. Only complaint — I wish it came in a berry flavor too.

  • Every batch of every KORE nutrition SKU is sent to an ISO/IEC 17025-accredited lab for identity, potency and banned-substance testing. Scan the batch code on the bottom of any container — the corresponding Certificate of Analysis loads instantly on our site.

  • Yes. Our nutrition line is Informed Sport and NSF Certified for Sport, meaning it is screened for the WADA prohibited-substances list. That certification is what lets us stock athletes across the NFL, MLB and Olympic pool.

  • No. Every active ingredient is listed with its full milligram dose on the label. If we can't defend the dose with published research, we don't put it in the bag.

  • ISO-Whey works best within 60 minutes of finishing a session — that's when whey isolate is absorbed the fastest. Night Recovery uses slow-release casein, so take it 30–45 minutes before bed to feed muscle repair through the night. They're designed to complement, not compete.

  • Free ground shipping on nutrition orders over $80 within the US. If a formula isn't working for you, we'll take it back within 60 days — even if the container is opened. No questions, no restocking fees.
