Gold Evidence Rating

Highest evidence tier · Primary claim backed by systematic reviews & meta-analyses.

🛡️

Every rated Kasivit supplement has passed our Evidence Review. Gold, Silver, and Bronze all meet our standard — the rating tells you the strength of the clinical research behind the primary claim, not whether the product is worth buying. We don’t list a Kasivit supplement unless it passes our review. View the Evidence Standard →

Why It Works

Key Benefits

💪
Strength & Power Output
Creatine replenishes phosphocreatine in skeletal muscle — the primary fuel for high-intensity contractions. This allows more total work per set and faster recovery between efforts. Multiple systematic reviews confirm significant improvements in one-rep max strength and peak power across resistance-trained and untrained populations.
🏋️
Lean Muscle Mass
The most replicated finding in creatine research: consistent 5g/day supplementation combined with resistance training produces greater gains in lean mass than training alone. Benefits extend to older adults — creatine is one of the few supplements with strong RCT evidence for muscle preservation in aging populations.
Exercise Performance
Creatine benefits extend beyond the weight room. Human trials show improved performance in sprint intervals, high-intensity cycling, and repeated-effort sports. The mechanism is consistent: faster phosphocreatine resynthesis between high-intensity bouts enables sustained output.
🧠
Cognitive Performance
Creatine is present in the brain, where it supports ATP production for neurons. Multiple controlled trials show improved cognitive processing under sleep deprivation and in aging populations taking creatine daily. This is a well-replicated finding in human subjects.
🛡️
Muscle Preservation
Creatine has been studied as a protective agent during periods of reduced activity, aging, and caloric deficit. RCTs in older adults and rehabilitation populations show it helps maintain lean mass when anabolic stimuli are reduced — making it relevant well beyond athletic performance.
This product is for you if…
You do resistance training or high-intensity exercise and want to support strength and power output
You are over 50 and want to preserve muscle mass and support healthy aging
You experience cognitive fatigue or work under high mental demand
You want to support muscle recovery between training sessions
You are looking for the most researched, evidence-backed performance supplement available
⚠️Consult your healthcare provider if…
You have chronic kidney disease or significantly reduced kidney function — creatine increases creatinine levels which can confuse kidney function lab results; consult your healthcare provider
You have a known creatine transporter deficiency (rare genetic condition)
You are under 18 — while creatine is generally considered safe, pediatric long-term safety data is limited

Science

Clinical Evidence

Every Kasivit product is backed by peer-reviewed research. Here's what the science says.

🔬
Creatine monohydrate supplementation over ten weeks showed a synergistic effect on aerobic power output in trained subjects
🔬
Post-workout creatine supplementation produced superior gains in lean mass and strength compared to pre-workout in a randomized controlled trial
🔬
Creatine supplementation increased brain creatine content in healthy human subjects, providing a plausible mechanism for cognitive and neuroprotective benefits
🔬
Cognitive processing impaired by sleep deprivation or aging can be improved with creatine supplementation in controlled human studies

Kasivit Creatine Monohydrate delivers 5,000mg of pure creatine monohydrate per serving — unflavored, with no fillers and nothing else. Creatine is the most extensively researched performance supplement in existence, supported by decades of human clinical trials and multiple independent systematic reviews across athletic performance, muscle preservation, and cognitive function.

What creatine monohydrate supports

  • Strength & power output — replenishes phosphocreatine stores used during high-intensity effort, enabling more work per set and faster recovery between efforts
  • Lean muscle mass — well-documented across resistance-training populations of all ages, including older adults
  • Exercise performance — benefits seen across resistance training, sprint intervals, and high-intensity work
  • Cognitive performance — creatine in the brain supports ATP production; human trials show benefit under sleep deprivation and in aging populations
  • Muscle preservation — studied in contexts of reduced activity, aging, and caloric restriction

The science behind creatine monohydrate

Creatine and athletic performance

A controlled study examining creatine monohydrate supplementation over ten weeks demonstrated a synergistic effect on aerobic power output in trained subjects. View source →

Creatine timing and body composition

A randomized trial found that consuming creatine immediately post-workout was superior to pre-workout supplementation for improvements in body composition and strength, suggesting timing may influence outcomes for those seeking muscle adaptations.

Creatine and brain energy

Creatine supplementation has been shown to increase brain creatine content in human subjects, providing a mechanism by which creatine may support cognitive function and neuroprotection beyond its musculoskeletal effects. View source →

Creatine and cognitive function

Multiple controlled studies demonstrate that cognitive processing — whether impaired experimentally through sleep deprivation or naturally through aging — can be improved with creatine supplementation, supporting its role as a brain energy substrate. View source →

Ingredients

Creatine Monohydrate (5,000mg per serving). No other ingredients.

Flavor: Unflavored  |  Manufacturer: USA  |  Amount: 250g (50 servings)  |  Gross Weight: 0.65 lb (295g)

Suggested use

Mix one (1) scoop (5g) in 8 oz of water or your preferred beverage and take once daily. No loading phase is required — consistent daily use at 5g produces equivalent long-term results over 3–4 weeks. Post-workout timing may offer a marginal advantage for muscle creatine resynthesis, or take at any time that suits your routine.

Warning

Keep out of reach of children. Do not use if the safety seal is damaged or missing. Store in a cool, dry place away from direct light. Individuals with kidney disease or a known medical condition should consult their healthcare provider before use.
