One Supplement Women Should Add To Their Rotation If They Want To Get Stronger

Women are no longer just sticking to the cardio machines at the gym. We're migrating in droves to the weight room—lining up for the squat racks and lifting increasingly heavy free weights and kettlebells. Our focus is no longer to be smaller but to be stronger. 

If building strength is on your agenda, pairing resistance training with adequate protein will be vital for building muscle. From there, one supplement could really give you a physical and mental edge: creatine.* 

Creatine is one of the most studied supplements out there. Creatine is a compound that the body makes naturally using the amino acids1 methionine, glycine, and arginine. 

This compound piqued the interest of gym goers first because about 95% of creatine is stored in muscles2, where it's used for energy. It's particularly important for energy production during short, high-intensity exercises, like lifting weights or sprints. So, not having enough stores of creatine during a workout may limit the energy or workload the muscle is able to handle. 

There's also a small amount of creatine stored in the brain3. 

A comprehensive review of creatine supplementation and women's health4 published in 2021 stated that supplementation is beneficial at every life stage—with very little risk. "Recent research has shown that supplementation with creatine can be beneficial for women's health during menstruation, postpartum, and peri- and postmenopause,"* says board-certified sports nutritionist Stevie Lyn Smith, M.S., RDN, CSSD.

"In premenopausal women, creatine can improve exercise and strength capacity. When it's alongside resistance training, creatine can lead to an increase in muscle mass and can potentially improve bone mineral density, particularly in postmenopausal women,"* Smith notes.

As creatine is also found in the brain, there's emerging evidence that creatine intake is linked to better mood regulation, improved cognitive performance6, and less mental fatigue.*

Women are more likely to experience sleep challenges7 (in part due to pregnancy and menopause) that impact mental capacity, further supporting the important potential of creatine supplementation for women.

Creatine supplements aren't associated with much risk. Creatine is widely studied and has a robust safety profile, it's also consumed in food in most diets. "The biggest pushback I hear from women is around the potential for some weight gain and bloating when starting creatine," says Smith. "But this is from cellular hydration—or water retention—in the muscles." 

With proper dosing, these effects can be minimized (more on this next), and they're not something everyone will experience. If individuals do experience these effects there's likely only a small and short-term increase in weight (that's due to water weight, not body fat) during the initial period of supplementation. These effects are also more associated with a "loading" dose phase, such as 20 grams a day.

New to creatine supplements? Set a strong base for yourself by starting with the right daily amount. Too much may lead to unwanted bloating, and too little won't have the effect you want. 

The recommended creatine dose for optimizing strength and muscle health is 5 grams per day8. Evidence suggests that a creatine intake of at least 3 grams a day is enough to provide significant health benefits, although many clinical trials support a 5-gram daily dose. Additionally, research suggests a 5 to 10 gram daily dose of creatine is good for supporting brain health4.

Most creatine supplements only come as creatine monohydrate. But you can choose to pair it with other cellular energy or strength-supporting ingredients like taurine. Similar to creatine, taurine is abundant in the muscles and the brain. Supplementing with this amino acid supports strength, power, endurance, and cognition.*
