Levelle Nutrition Launches First-Ever Cycle Syncing Protein Formulated for Women’s Unique Physiology

August 19, 2025

NEW YORK, NY (August 19, 2025) /SPORTSWIRE WOMEN/  – Levelle Nutrition today announced the official launch of its Cycle Syncing Protein, the first protein powder intentionally developed to support the shifting nutritional needs of menstruating women throughout their cycle. Despite the fact that women experience more than 450 hormonal cycles in a lifetime, the vast majority of protein supplements remain modeled on male physiology. Levelle’s Cycle Syncing Protein addresses this critical gap in the market by offering a clinically informed, phase-based solution tailored to the female body.

This launch arrives at a pivotal time for women’s health and performance. Recent reports highlight a long-overdue shift in the study of female biology, with women now comprising over 50% of newly launched clinical trials, according to Nature Medicine (2024). At the same time, mainstream attention to muscle health, metabolic support, and protein intake is on the rise, driven by the growth of GLP-1 weight loss drugs and the broader consumer movement toward functional nutrition (FMCG Gurus, 2025). In this context, Levelle’s Cycle Syncing Protein provides a real-food product that reflects both the science and lived experiences of women.

Created by Dr. Linda Alvarez, a physician-turned-formulator and co-founder of Levelle Nutrition, the Cycle Syncing Protein product is designed to meet the female body’s changing nutritional demands across the menstrual cycle with precision. The formulation is structured around two distinct phases. Phase 1, intended for Days 1–14, delivers 15 grams of protein, 25 grams of complex carbohydrates, and a targeted micronutrient blend rich in fiber, iron, potassium, magnesium, and zinc to support recovery and ovulation. Phase 2, covering Days 15–28, provides 22 grams of protein, 18 grams of carbohydrates, and a nutrient profile calibrated for energy, muscle tone, and inflammation resolution, including calcium, phosphorus, potassium, and zinc.

Early consumer response affirms the value of cyclical nutrition: 7 in 10 pre-sale customers opted for both Phase 1 and Phase 2, signaling a readiness among women for products designed to align with their physiology. This data suggests a clear demand for solutions that reflect a more nuanced and scientifically grounded understanding of women’s bodies.

Levelle’s Cycle Syncing Protein also marks a major advance in ingredient technology. The product is powered by effera™, a precision-fermented, human-identical lactoferrin developed by biotech company Helaina. Unlike bovine-derived lactoferrin, effera™ is structurally identical to the lactoferrin found in human milk.

effera™ is supported by dozens of preclinical and clinical studies, including a 2024 human safety study (Peterson et al.) demonstrating no antibody production against effera™, even at high daily doses. This confirms the body recognizes effera™ as its own, not as a foreign protein. The protein also breaks down into the same beneficial peptides as naturally occurring human lactoferrin, offering targeted support for immunity, gut health, and recovery.

“effera™ was born to serve women’s health from the inside out. Its inclusion in Levelle’s Cycle Syncing Protein speaks to the ability of modern biotechnology to support complex physiological processes safely and accurately,” said Laura Katz, Founder and CEO of Helaina. “This represents an important step forward in making precision nutrition accessible and effective for women.”

Levelle Nutrition has been recognized by the Nutrition Business Journal with a Growth and Innovation Award for its leadership in female-focused product development. The company’s growing portfolio includes its signature line of real-food-based performance gels, also designed specifically for female athletes.

Levelle intends to continue its focus on women’s life stages, and is in the process of formulating a protein powder targeting menopause and post-menopause. Each product reflects Levelle’s commitment to evidence-based formulation, clean ingredients, and the advancement of women’s performance through science.

“This isn’t just about macros. It’s about giving women a protein powder that finally reflects their physiology, their performance, and their potential,” said Dr. Alvarez. “This product reflects what women have needed all along: nutrition that keeps pace with their physiology, not the other way around.”
