THE SCIENCE BEHIND SIXCORE
Every ingredient. Every dosage. Backed by peer-reviewed research. Built for performance without compromise.
CREATINE MONOHYDRATE
5,000mg of pure creatine monohydrate per serving — the gold standard dose validated by decades of research. No loading phase required. No bloating. Just results.
Clinical gold standard. 5g daily is the most researched dose — proven to saturate muscle creatine stores without excess.
Increases muscle strength by 8-20% in resistance training
Supports muscle growth by enhancing workout capacity and recovery
Improves high-intensity exercise performance and delays fatigue
Supports mental performance under stress and sleep deprivation
Meta-analysis of 22 studies: creatine supplementation with resistance training increased muscle strength by 8% more than placebo (20% vs 12% strength gains).
View StudySystematic review of 22 trials (721 participants): creatine supplementation resulted in 1.37kg greater increase in lean tissue mass and significant improvements in both upper and lower body strength.
View StudyELECTROLYTE COMPLEX
Four essential electrolytes in citrate and bisglycinate forms for superior absorption. Optimized ratios to support hydration, muscle function, and sustained performance without GI distress.
Primary electrolyte for fluid balance and nerve function. Citrate form buffers lactate accumulation.
Critical for muscle contraction and blood pressure regulation. Prevents cramping during intense exercise.
Highest bioavailability magnesium form. Supports 300+ enzymatic reactions, muscle recovery, and sleep quality.
Essential for bone health and muscle contraction. Citrate form absorbs independently of stomach acid.
Study of electrolyte drinks rich in sodium and potassium before/after exhaustive exercise showed significant improvements in body water utilization and recovery. Sodium and potassium levels significantly increased with electrolyte supplementation compared to regular water.
View StudyComprehensive review found that beverages containing both sodium and potassium displayed important fluid retention properties for rehydration. Optimal sports drinks should contain 400-1,100mg/L sodium plus potassium for rapid intestinal absorption.
View StudyCrossover study comparing magnesium oxide, citrate, and bisglycinate: bisglycinate demonstrated superior absorption with significantly lower GI side effects.
View StudyVITAMIN COMPLEX
Four bioavailable vitamins chosen for synergy with creatine and electrolytes. Not a multivitamin — a targeted formula to amplify performance, recovery, and long-term health.
Potent antioxidant supporting immune function, collagen synthesis, and exercise recovery. Reduces oxidative stress from training.
Essential for calcium absorption, bone health, and immune function. D3 is the most bioactive form.
Directs calcium to bones (not arteries). MK-7 has longest half-life. Works synergistically with D3.
Active methylated form. Supports energy metabolism, red blood cell formation. No conversion required.
49.5% of UK adults had vitamin D levels below optimal range (75-100 nmol/L). Average level was 75 nmol/L. Women averaged 73 nmol/L, below minimum. Ages 18-29 had lowest levels (70 nmol/L) with 56% deficient.
View StudySevere vitamin D deficiency (≤25 nmol/L) prevalence: 57.2% of Asians in winter/spring, 38.5% of Black Africans, 17.5% of White Europeans. Lower socioeconomic areas showed highest deficiency rates. Study calls for targeted public health interventions.
View StudyIn large UK surveys, approximately 6% of adults aged ≥60 are vitamin B12 deficient (plasma B12 <148 pmol/L), with prevalence increasing with age. Closer to 20% have marginal status (148-221 pmol/L) in later life.
View Study12.4% of UK women aged 19-39 were B12 deficient (≤150 pmol/L) despite 96% consuming more than the RNI of 1.5 μg/day. Study recommends UK RNI increase to 5-7 μg/day for stable biomarker levels.
View Study2-week vitamin C supplementation (200mg twice daily) had modest beneficial effects on muscle soreness, muscle function, and plasma malondialdehyde after prolonged intermittent exercise. Plasma IL-6 was lower in vitamin C group 2 hours post-exercise.
View Study4-day supplementation with vitamin C (2,000mg/day) and E effectively attenuated exercise-induced tissue damage and inflammatory response during 4 consecutive Taekwondo matches. Short-term antioxidant use beneficial for competition recovery without impairing training adaptations.
View StudyQUALITY & TESTING
Third-party tested for purity, potency, and safety. Every batch screened for heavy metals, microbial contamination, and label accuracy. No shortcuts.
