About

PhazeFuel makes science-backed nutrition products designed for female athletes who refuse to let their menstrual cycle slow them down.

PhazeFuel was founded by Leah Klingel, a student-athlete at the University of Tampa, after she could not find a single sports supplement designed for female physiology.

Why We Exist

The supplement industry was built for men. Research studies are conducted on male athletes. Formulas are designed for male physiology. Women are told to just take the same thing — maybe in a smaller dose, definitely in a pink bottle.

But female athletes are not small men. Your hormones fluctuate. Your recovery needs change throughout the month. Your energy demands shift with your cycle. And yet — walk into any supplement store and try to find something actually designed for you.

You will not find it. So we built it.

What Makes PhazeFuel Different

  • Research-backed formulation. Every ingredient is supported by peer-reviewed research conducted on female populations. No trends. No hype.
  • Clean label. No artificial sweeteners, no proprietary blends, no fillers. Every ingredient listed with its exact dose.
  • Designed for athletes. Not a multivitamin with a fitness label. Not a wellness brand that dabbles in sports. Built from the ground up for women who train hard and compete harder.

Who This Is For

PhazeFuel is for female athletes ages 18–35 who:

  • Train consistently and compete seriously
  • Experience menstrual cycle symptoms that affect performance
  • Want science-backed support without synthetic hormones
  • Care about what goes into their body

Our Commitment

We will never make exaggerated health claims. We will never hide ingredient doses in proprietary blends. We will never use artificial additives just to make a product taste better. And we will never forget who we are building this for.

Every decision — from formulation to packaging to marketing — is made with one question: Does this serve female athletes better?

If the answer is no, we do not do it.
