Why CHRY Works for Women: The Science Behind Our Formula

Tart Cherry: Natural Anti-Inflammatory & Sleep Support

Montmorency tart cherry contains anthocyanins — the deep red pigments responsible for its potent antioxidant and anti-inflammatory properties. What makes tart cherry especially relevant for women is how it supports the body's inflammatory response: by interacting with cyclooxygenase-2 (COX-2), the same enzyme targeted by NSAIDs like ibuprofen. This pathway is involved in many of the inflammatory processes women experience monthly.

A 2018 study in the American Journal of Therapeutics (Losso et al.) found that tart cherry juice was associated with increased sleep time and improved sleep efficiency in adults with difficulty sleeping. The mechanism? Tart cherry's procyanidin B-2 increases tryptophan availability — a precursor to both serotonin and melatonin. This dual-pathway effect on both mood and sleep makes tart cherry particularly compelling for women.

In 2022, Gratwicke et al. published a randomized controlled trial in the International Journal of Environmental Research and Public Health specifically studying elite female field hockey players. Tart cherry juice improved sleep quality around competitive matches and supported recovery from exercise-induced inflammation — one of the few tart cherry studies conducted exclusively in women.

Creatine: Not Just for Gym Bros

Creatine has an image problem. Most women associate it with bulky bodybuilders and water retention. The reality? Creatine may be more important for women than men — and the research is striking.

Women have 70–80% lower endogenous creatine stores than men, according to a 2021 comprehensive review in Nutrients by Smith-Ryan et al. titled “Creatine Supplementation in Women's Health: A Lifespan Perspective.” The review found that due to hormonal changes across the menstrual cycle — particularly fluctuations in estrogen and progesterone that affect creatine kinase activity — supplementation may be especially important during the luteal phase when performance and energy levels naturally dip.

But perhaps the most remarkable finding comes from mood research. A 2012 randomized, double-blind, placebo-controlled trial published in the American Journal of Psychiatry (Lyoo et al.) studied 52 women and found that those who received creatine alongside standard care showed significant improvements in mood scores as early as week 2. These findings suggest creatine may play a role in supporting brain energy metabolism related to mood regulation.

A follow-up brain imaging study by Kondo et al. (2016) in Amino Acids showed that creatine supplementation increased frontal lobe phosphocreatine levels in adolescent females in a dose-dependent manner. These brain energy levels were associated with mood regulation scores, suggesting creatine may support the brain's energy-intensive mood-regulating regions.

More recently, Gordon et al. (2023) in Nutrients studied 39 active women across their menstrual cycles and found that creatine supplementation may help counteract the performance decrements women experience in the luteal phase — the high-hormone phase before your period when energy, strength, and motivation often plummet.

Magnesium: The Women's Wellness Mineral

If there's one mineral premenopausal women are most likely to be deficient in — and most likely to benefit from supplementing — it's magnesium. Research suggests women may have lower magnesium concentrations during certain phases of the menstrual cycle, particularly the luteal phase. And the evidence for supplementation is compelling.

A 1991 double-blind study in Obstetrics & Gynecology (Facchinetti et al.) gave 32 women either magnesium or placebo from day 15 of their cycle to the onset of menstruation. By the second cycle, the magnesium group reported improvements in mood-related scores on the Menstrual Distress Questionnaire.

Walker et al. (1998) in the Journal of Women's Health found that daily magnesium supplementation was associated with improvements in premenstrual comfort compared to placebo. CHRY provides 300mg of magnesium glycinate per serving.

A 2017 systematic review in Magnesium Research by Parazzini et al. brought the evidence together, concluding that magnesium supplementation may support women's comfort and wellbeing during the menstrual cycle.

CHRY uses magnesium glycinate — a chelated form bound to two molecules of the amino acid glycine. Compared to common forms like magnesium oxide, glycinate has significantly better absorption and is gentler on the stomach. The glycine itself has additional calming effects, making this form ideal for evening use.

L-Theanine: The Cortisol Antidote

L-theanine, an amino acid found in green tea, is known for promoting a state of calm focus. But its most important benefit for premenopausal women may be its direct effect on cortisol — the stress hormone that, when chronically elevated, can disrupt the hypothalamic-pituitary-gonadal (HPG) axis and worsen PMS, menstrual irregularities, and sleep problems.

Hidese et al. (2019) published a randomized controlled trial in Nutrients with a study population that was 70% female. After 4 weeks of 200mg L-theanine daily — the same dose in CHRY — participants showed significant decreases in depression (p=0.019), anxiety (p=0.006), and sleep disturbance (p=0.013). Verbal fluency and executive function also improved.

The cortisol-lowering effect works fast, too. Scholey et al. (2021) in Neurology and Therapy demonstrated that a single 200mg dose of L-theanine significantly reduced salivary cortisol within 1 hour (p<0.001) and increased alpha brain wave activity — the signature of relaxed alertness — compared to placebo.

In 2023, Rao et al. published a study in Food & Function conducted specifically in healthy young women, finding that L-theanine maintained sleep quality by suppressing caffeine-induced wakefulness after sleep onset — particularly relevant for women who consume caffeine earlier in the day and struggle with sleep later.
