Creatine Sees Surge in Popularity, Particularly Among Women

Once associated primarily with bodybuilders, creatine is experiencing a significant surge in popularity, with women now leading the demand. Analytics platform SmartScout reported that searches for terms like 'creatine for women' have risen by more than 300% year-on-year, indicating a substantial shift in the supplement's user base.

Wellness industry data suggests that women now constitute nearly half of all new creatine buyers. This trend transforms creatine from a niche product for male athletes into a widely adopted supplement for various demographics, including midlife women.

What is Creatine? Creatine is a naturally occurring compound produced by the body from amino acids. While the body synthesizes some creatine, dietary intake or supplements are needed to reach higher levels. Foods rich in creatine include red meat and fish. However, obtaining gram-level doses solely through diet can be challenging, with a common supplemental dose for healthy adults being 3-5 grams per day. Nutritional therapist Kirsten Humphries noted that many individuals do not consume enough creatine-rich foods to meet these levels.

Humphries also clarified that creatine supplements are typically vegan and vegetarian-friendly, making them accessible for those avoiding animal products. She particularly encourages vegans and vegetarians to consider supplementation due to their lower dietary intake.

How Creatine Works Creatine plays a crucial role in energy production by helping to regenerate adenosine triphosphate (ATP), the body's primary energy molecule. Approximately 95% of creatine is stored in the muscles, where it exists as free creatine or phosphocreatine. During intense physical activity, phosphocreatine can donate a phosphate group to adenosine diphosphate (ADP), enabling the rapid resynthesis of ATP. This process allows for sustained energy output during short, high-intensity efforts, supporting improved training performance and recovery.

Dr. Alan Desmond, an NHS gastroenterologist and GP, confirmed that creatine's established role is in energy regeneration during exercise. He also cited evidence suggesting it can help preserve or increase muscle mass when combined with resistance training. This is particularly relevant for women in midlife and beyond, as maintaining muscle mass is crucial for metabolic health, bone density, mobility, and overall independence.

Emerging research also points to potential benefits for cognition, memory, and healthy aging, although this evidence is still considered promising rather than definitive.

Nutritional therapist Emma Bardwell highlighted creatine's potential as a "game-changer" during perimenopause and menopause, a period often associated with hormonal shifts that can lead to muscle loss, changes in metabolism, and cognitive fog. Bardwell emphasized that creatine's benefits are maximized when combined with consistent resistance exercise.

Addressing Myths Despite a strong safety record, several myths persist regarding creatine supplementation.

Water Retention: Creatine can cause a degree of water retention as it draws water into muscle cells. This may lead to a slight, temporary increase in body weight but is not indicative of fat gain and typically subsides. IMAGE2 Kidney Damage: In healthy individuals, recommended doses of creatine have not been shown to impair kidney function. However, creatine supplementation can slightly elevate blood creatinine levels, which might affect the interpretation of kidney function tests. Individuals with pre-existing kidney conditions should consult their doctor before use. Hair Loss: One study noted an increase in dihydrotestosterone (DHT) levels in rugby players taking creatine, a hormone linked to hair loss. However, this finding has not been consistently replicated, and other studies have not demonstrated a causal link between creatine and hair loss. Tummy Troubles: Some individuals may experience gastrointestinal issues like bloating or nausea, particularly when starting with high doses or if they have a sensitive stomach. Using micronized creatine powder and starting with lower doses (e.g., 2.5 grams per day), gradually increasing over time, can help mitigate these effects. IMAGE1

Experts advise caution and consultation with a healthcare provider for individuals with conditions such as endometriosis or pre-existing kidney issues before starting creatine supplementation.
