If you’ve ever dismissed creatine as just another muscle-building supplement for bodybuilders and gym bros, here’s a wake-up call: science is rewriting that script. Although Dwayne "The Rock" Johnson may still be spiking it into his post-gym smoothies, a previously unexpected new population is on to creatine—middle-aged women, health-conscious enthusiasts, and even professionals seeking to enhance cognitive function. Ivanka Trump breezily discussed it in her smoothie regimen, and TikTok is filled with users raving about its mood and mental performance benefits but let's get past anecdote. What is the science really suggesting?

What Is Creatine?

Creatine is a naturally occurring substance, synthesized primarily by the liver, kidneys, and pancreas, and also produced in muscles and the brain. We also obtain trace amounts from animal foods like red meat and fish.

The typical individual produces approximately one gram of creatine per day, but the optimal dose for maximum benefit is three to five grams daily—so most, particularly women (who tend to consume less meat), don't notice.

Creatine's first and foremost function is to assist in the regeneration of ATP, the molecule behind everything from bicep curls to brain activity. Until recently, its fame did not extend beyond the doors of the gym. Today, however, scientists are learning it could have applications in cognitive health, mood stabilization, and even disease prevention.

Cognitive and Mental Health Benefits of Creatine

Perhaps one of the most persuasive discoveries in recent years is the effect of creatine on the brain.

Creatine aids energy metabolism within the brain, which is essential in sustaining attention, memory, and emotional control—most especially during stress. A number of studies demonstrate that supplementation with creatine can decrease brain fog and fatigue and improve working memory.

In one study, conducted by the University of Kansas Medical Center, creatine supplements were linked to enhanced executive function and memory in Alzheimer's patients. In another study, individuals with depression who received a supplement of creatine along with cognitive behavioral therapy were found to have improved more quickly than those receiving therapy alone.

The link? Low levels of creatine have been correlated with decreased brain energy and neurotransmitter activity—factors that affect everything from mood to choice.

Why Women Might Gain Even More

Now comes the interesting part: women generally have lower creatine levels than men, both because they have less muscle mass and due to dietary habits. Studies show that hormonal changes—particularly during menstruation, pregnancy, and menopause—might also influence how creatine is synthesized, transported, and stored.

Menstruation and menopause, when estrogen levels are low, also make women susceptible to fluctuations in energy, muscle function, and mood. Creatine can level out these dips. It's also been found to lower muscle loss and help keep bones strong—something important for women as they grow older.

In one 12-month trial, postmenopausal women who took creatine supplements maintained better bone mineral density than those who didn't.

Early research also indicates that creatine may be involved in pregnancy complications. Evidence indicates that lower levels of maternal creatine are linked with increased stillbirth, premature birth, and reduced birth weight. Though supplementation is not yet routine or even proven safe, scientists are taking particular interest.

Interestingly, researchers have also calculated how much creatine infants would require—about 7–8.4 mg a day based on age—even though breast milk contains only a small proportion of that amount.

And then there's long COVID: women are more susceptible to it, and researchers think that variations in creatine metabolism could help explain why, in part. Since creatine helps with cellular energy, it could aid in alleviating fatigue and brain fog in long COVID patients.

As cognitive and hormonal benefits are hogging the limelight, the traditional muscle benefits of creatine haven't disappeared.

Creatine is a performance powerhouse for physical activity—particularly for short durations of high-intensity exercise. Research indicates it can enhance strength, endurance, and recovery, making it perfect not only for bodybuilders but also for anyone concerned with age-related muscle loss (sarcopenia). Approximately 5% to 16% of adults aged over 65 suffer from sarcopenia, and creatine has the potential to counteract this.

It also increases intracellular water in muscle cells, which increases hydration and muscle mass. That's why other users become bloated—a normal but normally harmless side effect.

How Much Creatine Is Enough?

General health requires 3–5 grams daily according to most experts. Creatine monohydrate is still the standard: it's the most researched, most affordable, and most bioavailable variety.

One scoop (roughly 5 grams) mixed into water or a smoothie is enough for most people. What matters most is consistency—it takes a few weeks for the body to fully saturate its creatine stores.

When to take it? Research is still mixed. Some prefer post-workout, others in the morning. The key is regularity rather than timing.

Is Creatine Safe for Everyone?

For healthy adults in general, creatine is very safe when used as directed. But it's not suitable for everybody.

It should be avoided by individuals with kidney disease or a history of kidney transplant. There are also problems for individuals who have bipolar disorder. Creatine is filtered through the kidneys, and in exceptional instances, has been connected to liver stress.

It's not yet indicated in pregnancy or lactation for a lack of definitive safety studies. Always consult a healthcare professional before supplementation—particularly if you're on drugs or dealing with chronic illness.

A just-released study that included 25,000 adults aged over 52 discovered a convincing association: each 0.09-gram boost in creatine consumption corresponded with a 14% reduced risk of cancer.

While preliminary and not definitive, this contributes to a steadily expanding list of possible advantages, such as antioxidant activity, improved mitochondrial function, and even possible tumor-inhibiting effects in animal models.

Creatine is experiencing a renaissance—and not only among jocks. With increasing evidence validating its cognitive function benefits, mental health benefits, bone mineral content benefits, and hormone regulation benefits, creatine is becoming an all-around staple beyond the weight room.

It's not just about gaining muscle anymore. It's about fueling total-body vitality, brain resilience, and optimal long-term health.

If you're a woman going through hormonal shifts, a senior looking to remain resilient, or anyone interested in brain wellness, creatine may be worth reconsideration.

Dwayne “The Rock” Johnson has always been synonymous with strength, charisma, and an iconic muscular frame. But this week, fans barely recognized him. At 53, the actor unveiled a dramatically slimmer look while promoting his latest film, The Smashing Machine, leaving social media buzzing. Dropping an astonishing 60 pounds for his role as MMA champion Mark Kerr, Johnson’s transformation has sparked curiosity, how did one of Hollywood’s most ripped stars achieve such a drastic change and could it really be done safely? From diet tweaks to intense training, this transformation is surely a masterclass in discipline, science, and sheer determination.

From his WWE wrestling days to blockbuster hits like Fast & Furious and Black Adam, his signature look has been about size, strength, and power. But when he stepped onto the red carpet at the 82nd Venice International Film Festival, fans were stunned. Johnson, 53, appeared dramatically slimmer, having shed close to 60 pounds for his role in The Smashing Machine, a biopic about MMA legend Mark Kerr.

Clad in a sharp double-breasted suit and subtle glasses, Johnson looked nearly unrecognizable. Social media lit up with reactions ranging from admiration to disbelief. “The Rock turned into a pebble,” one fan quipped on X, while others speculated whether Hollywood’s latest weight-loss trend—injectables like Ozempic or Mounjaro played a role.

So how did the world’s most famous action star pull off such a radical transformation?

Dwayne Johnson Weight Loss: The Acting Role That Sparked a Transformation

The Smashing Machine, tells the turbulent story of Mark Kerr, a former NCAA wrestling champion; to do justice to Kerr’s complicated journey, Johnson didn’t just rely on prosthetics and wigs. He physically reshaped his body to mirror the leaner, battle-worn frame of an MMA fighter from the late 1990s. Speaking at Venice, Johnson admitted:

“This transformation was something I was really hungry to do. I’ve been fortunate in my career, but there was a little voice inside me that said, ‘What if I could do more?’”

How Did Dwayne Johnson Lost 60 Pounds?

Dropping 60 pounds is not a casual feat, especially for someone with Johnson’s naturally muscular build. It requires precision, planning, and science-backed strategies. Here’s a breakdown of what likely fueled his transformation:

1. A New Approach to Nutrition

Johnson has long been known for his intense, protein-rich “cheat meals” and high-calorie fueling. But slimming down for The Smashing Machine would have meant rethinking everything.

Caloric Deficit: To lose weight, he would have needed to burn more calories than he consumed daily. Reports suggest that his intake was strategically lowered while still supporting performance and energy.

Lean Proteins: While reducing muscle bulk, protein remains essential for muscle maintenance. Sources like grilled fish, egg whites, and lean chicken likely became staples.

Lower Carbs, Smarter Fats: Instead of bulking carbs, Johnson likely shifted toward complex carbs (like sweet potatoes and oats) and healthy fats (avocados, olive oil, nuts).

Hydration and Water Manipulation: A technique Johnson previously described during Black Adam prep. Adjusting water and sodium intake helps achieve a leaner, tighter look.

2. Training Like a Fighter, Not a Bodybuilder

Unlike superheroes or action roles that required maximum size, portraying Kerr demanded a more athletic, fight-ready build. Johnson’s training likely included:

Functional Strength Workouts: More bodyweight exercises, compound lifts, and fight-specific movements rather than sheer heavy lifting.

Cardio Conditioning: Interval training, long sessions of steady-state cardio, and possibly combat drills to replicate an MMA fighter’s stamina.

Mobility & Agility Training: Essential for replicating Kerr’s fighting style and reducing the risk of injury at 53.

Did Dwayne Johnson Use Ozempic or Fat-Loss Injections?

The internet buzzed with speculation about whether Johnson joined the list of celebrities turning to medications like Ozempic or Mounjaro, designed for diabetes but widely used for rapid weight loss.

There’s no confirmation from Johnson himself, and given his history of meticulous training regimens and diet transparency, it seems more plausible that his transformation was the result of strict lifestyle changes rather than pharmaceutical shortcuts.

Still, experts note that rapid and dramatic changes like this are usually only sustainable under professional supervision something Johnson has access to with his longtime trainer, Dave Rienzi.

This isn’t the first time Johnson has dramatically altered his physique for a role. For Black Adam (2022), he revealed how he worked “harder than ever” on dieting and training, manipulating sodium and water retention to achieve a superhero’s shredded frame.

The difference this time? Instead of aiming for mass and density, he trimmed down to reflect vulnerability, endurance, and realism. It’s a striking reminder that body transformations in Hollywood aren’t always about getting bigger—they’re about embodying a character.

Why Are Celebrity Weight Loss Transformations Becoming Popular?

Johnson’s transformation adds fuel to the ongoing discussion about how actors reshape their bodies for roles. Christian Bale, Matthew McConaughey, and Joaquin Phoenix all underwent dramatic shifts for character authenticity. But for Johnson a man defined by his physique it’s particularly startling.

His leaner frame also resonates with broader health conversation and the possible use of weight loss injections to transform into a leaner more "fitter" body. With obesity rates soaring and plant-based diets, intermittent fasting, and medical interventions gaining traction, fans are asking whether their favorite stars are adopting the same tools everyday people use—or something far more extreme.

Fitness Lessons You Can Apply To Your Journey

Dwayne Johnson’s new look may be for a role, but it underscores timeless lessons about health and body transformation:

1. Significant weight changes require discipline, nutrition, and tailored exercise.
2. Quick fixes, like weight-loss injections, remain controversial and should be supervised by medical professionals.

Even at 53, with the right guidance, it’s possible to reshape your body dramatically though sustainability depends on balance, not extremes.

Johnson has proven once again that his career is about more than action-hero brawn. His latest transformation shows he’s still willing to push physical and emotional limits to tell a story reminding fans that even “The Rock” is capable of change.

When you hear the word exercise, your mind probably jumps to images of sweat-covered gyms, thudding treadmills, and high-intensity interval training. But what if the most overlooked type of movement—the kind that doesn't really feel like exercise at all—had incredible health benefits? Welcome to "zone zero" exercise, a strategy that flips conventional fitness wisdom on its head.

Zone zero is very low-intensity activity, slower and more relaxed than most fitness trackers would call zone one. It's activity so relaxed that you could talk easily the whole time. It's the opposite of stressing yourself to the limit: a walk around the block, some gentle yoga movement, stretching waiting for your coffee, or even light gardening. Athough it looks simple, zone zero can enhance health indicators, promote mental health, and even provide for longevity.

What are Zone Zero Workouts?

In endurance training, heart rate zones are used to organize workouts. Zone one is generally around 50-60% of your maximum heart rate—a slow, aerobic pace. Zone zero falls even lower, usually just above complete inactivity. Sports scientists argue whether it should be considered its own category, but its idea has drawn attention because it is so accessible and may have benefits.

Zone zero cares less about performance metrics and more about sustainability and consistency. It reminds us that it is better to move, albeit slowly, than to sit. In a world of sedentary lifestyle and intense fitness culture, the slow pace of zone zero provides an alternative, more sustainable way.

Zone Zero: Does Science Support Moving Slowly?

Zone zero advantages go beyond convenience. Research indicates even small amounts of physical activity can increase circulation, stabilize blood sugar, and promote mental health. Slow motion stimulates glucose uptake in muscles after eating, reducing the likelihood of insulin resistance and type 2 diabetes.

Light exercise also accesses fat stores for energy more efficiently than high-intensity workouts, which depend so much on glucose. A leisurely walk, or even standing at work, can slowly lower body fat while improving cardiovascular health.

Recovery is another significant benefit. Intensive training requires rest to rebuild muscles and restore energy. Zone zero offers a restful alternative. It melts stress and tension without draining energy resources, making it suitable for working professionals or family and work-committed individuals.

Mental Health and Consistency

Perhaps the most underappreciated aspect of zone zero is its mental health benefits. Low-intensity activity promotes mindfulness, alleviates stress, and helps regulate mood. It also helps build habits. Individuals are more likely to maintain a practice that is low-stress and feels accomplished, translating to compounded dividends: improved sleep, enhanced life satisfaction, and decreased risk of chronic illness.

Even on stressful days or lazy workdays, zone zero enables one to stay active. Small actions, such as dog walking, standing over a cup of coffee while reading emails, or a leisurely post-lunch walk, can, over time, change the mood, energy, and overall health.

Does Zone Zero Fit in 'Busy' Modern Lifestyle?

For some, fitness guidance can be overwhelming: steps, intensity, frequency. Zone zero makes it easy. It's about incorporating movement into daily life organically. Long periods of sitting are associated with higher health risks, even among people who do vigorous exercise sporadically. Regular, low-key activity can counteract these risks and supplement more intense exercise.

For athletes, zone zero provides a strategic advantage. Scientists have found that faster marathon runners spend much of their race in low-intensity zones, becoming endurance-building without exhausting themselves. Low-intensity movement might help recovery, rebuild heart structure, or prime slow-twitch muscle fibers, all leading to improved performance over time.

Can Anyone Do Zone Zero Exercise?

Zone zero is not reserved for elite athletes or those in their golden years; it can be tailored for anyone. Its greatness is accessibility. No equipment, heart rate monitors, or strict regimens are necessary, unlike traditional training. Anyone can weave gentle movement into the day and gain both acute and chronic health benefits.

Whether it's a retiree wanting to stay mobile, a working professional needing stress relief, or an injury returnee, zone zero provides a low-barrier way to get into regular exercise. Its focus on sustainability ensures movement becomes a lifelong practice and not a temporary commitment.

How to Add Zone Zero Exercise In Your Workout?

Following are practical suggestions for integrating zone zero in everyday life:

Gentle Walking: A leisurely neighborhood walk, short post-meal walks, or walking on the phone.

Easy Yoga or Stretching: Add stretches to your morning and evening routine without exhausting yourself.

Gardening and Yard Work: Light digging, planting, or weeding is low-intensity exercise.

Standing Activities: Employ standing desks or switch between sitting and standing while working.

Household Chores: Cleaning, dusting, or tidying up keeps your body in motion without structured exercise.

Casual Cycling: A slow bike ride at a speed that permits normal conversation.

Active Breaks: Brief, slow walks during work breaks to interrupt extended periods of sitting.

Recreational Hobbies: Light dancing, tai chi, or easy play with children or pets.

Zone zero contradicts conventional notions of how exercise "ought" to be. Its merit is not in intensity but in regularity, accessibility, and accumulation of benefits. Even small, persistent movement can boost circulation, stabilize blood sugar, improve mental well-being, and lead to longevity.

In a culture that values efficiency and peak performance, the idea of flowing slowly may seem contradictory. But growing evidence demonstrates that on occasion the easiest, slowest way is the one most likely to have significant implications for health, fitness, and well-being.

Our hearts works very hard to make sure we have the energy and strength to do everything we need. However, as gracious our organs are to us, most of us are not as helpful back to it. Whether it is eating junk food, not exercising, sleeping late etc. However, did you know, your heart is not the only one bearing the burden? You also have another heart in your body contributing to your health.

Heart transplant cardiologist Dr. Dmitry Yaranov calls your calf muscles your "second heart" for a very good reason. When you move your legs, these muscles squeeze and relax, which helps push blood back up toward your main heart.

This pumping action is essential for good circulation throughout your body. Without it, blood can pool in your lower legs, making it harder for your heart to work. By keeping your calf muscles strong, you help your body's entire circulatory system run smoothly, which can prevent problems like dangerous blood clots.

How Your ‘Sitting’ Lifestyle Is Killing Your Heart

Our modern lives often involve a lot of sitting, which is a big problem for our calves and our hearts. When we don't use our calf muscles, they weaken and lose their ability to pump blood effectively.

Dr. Yaranov warns that this forces your main heart to work much harder to circulate blood on its own. Over time, this extra strain can cause circulation to slow down, leading to swelling in your legs, high blood pressure, and a much higher risk of heart failure. No pill can replace the natural, powerful benefits of simply moving your body.

Simple Ways to Keep Your Calves Strong

The good news is that you can easily strengthen your calf muscles without a gym. Dr. Yaranov suggests simple changes to your daily routine. Try to walk every day to get your blood flowing.

You can also do calf raises while you're sitting at your desk or waiting in line at the grocery store. Whenever possible, choose to take the stairs instead of the elevator. These small, consistent actions will help keep your "second heart" strong and healthy for life, which in turn protects your main heart.

Calf Exercises You Can Do At Home

Calf Raises

Stand with your feet flat on the ground. Slowly lift your heels as high as you can, balancing on your toes, then lower yourself back down with control. Repeat for several repetitions to build strength.

Single Leg Calf Raise

Stand on one leg, using a chair or wall for balance. Lift your heel as high as possible, then lower it back down slowly. This variation helps improve your balance and builds strength one leg at a time.

Standing Calf Stretch

Stand a few feet from a wall and place your hands on it. Step one foot back and lean forward, keeping your back heel on the floor to feel a deep stretch in your calf. Hold for 30 seconds.

Dumbbell Calf Raise

Hold a dumbbell in each hand. Stand with your feet flat on the ground. Lift your heels and rise up onto your toes. Squeeze your calf muscles at the top before slowly lowering yourself back down.

Seated Calf Raise

Sit on a chair and place your feet flat on the floor. Place a heavy book or a dumbbell on your knees for weight. Lift your heels as high as you can, then slowly lower them for a controlled movement.
