What Goes Into Every KYRONFIT Supplement
We believe you have the right to know exactly what you're putting in your body. No proprietary blends. No hidden fillers. Just clean, science-backed ingredients at effective doses.
We Only Use What Your Body Needs
The supplement industry is full of products packed with cheap fillers, artificial colours, and underdosed "proprietary blends" that hide exactly how little of the active ingredient you're actually getting.
At KYRONFIT, every ingredient is chosen based on three criteria: scientific evidence for effectiveness, safety at the doses we use, and sourcing transparency from our suppliers.
We list every ingredient and every dose clearly on our labels. Always.
We use the same doses proven effective in human clinical trials — not token amounts added just to put an ingredient on the label.
Zero artificial colours, sweeteners, flavours, or preservatives. Ever.
Every raw material is tested for purity before use. Every finished batch is independently tested before shipping.
Made in facilities certified to Good Manufacturing Practice standards — the same standard as pharmaceutical production.
Key Ingredients We Use & Why
These are the science-backed compounds you'll find across our product range.
Ashwagandha (KSM-66®)
Sleep · Stress · RecoveryOne of the most researched adaptogens in the world. KSM-66® is the highest-concentration full-spectrum ashwagandha root extract available. Clinical studies show it significantly reduces cortisol (stress hormone), improves sleep quality, and supports muscle recovery.
Magnesium Glycinate
Sleep · Muscle Function · Blood SugarMagnesium is involved in over 300 enzymatic reactions in the body. Glycinate is the most bioavailable form — far better absorbed than cheaper oxide forms. It supports deep sleep, muscle relaxation, blood sugar regulation and nervous system health.
L-Theanine
Focus · Sleep · Calm EnergyA naturally occurring amino acid found in green tea. L-Theanine promotes a state of "calm alertness" — reducing anxiety and improving focus without sedation. Combined with caffeine, it smooths out energy spikes. Alone, it aids sleep quality and mental clarity.
Rhodiola Rosea
Energy · Mental Performance · FatigueA powerful adaptogen used for centuries in Scandinavian and Russian traditional medicine. Clinical evidence shows Rhodiola reduces physical and mental fatigue, improves exercise performance, and supports cognitive function under stress.
Berberine HCl
Blood Sugar · Metabolism · Gut HealthOne of the most studied natural compounds for metabolic health. Berberine activates AMPK — often called the "metabolic master switch" — to support healthy blood glucose levels, lipid metabolism, and gut microbiome balance.
Vitamin D3 + K2
Immunity · Bone · Recovery · MoodVitamin D3 is essential for immune function, mood regulation, muscle strength, and bone health. Combined with K2, it ensures calcium is directed to bones rather than arteries. Over 40% of Europeans are deficient in Vitamin D, especially in winter months.
Probiotics (Multi-Strain)
Digestion · Immunity · Gut HealthWe use a multi-strain probiotic blend including Lactobacillus and Bifidobacterium species, chosen for their clinical evidence in supporting gut microbiome diversity, reducing bloating, improving digestion, and strengthening immune response.
B-Vitamin Complex
Energy · Nervous System · MetabolismB-vitamins are essential co-factors for energy production in every cell of your body. Our complex includes B1, B2, B3, B5, B6, B9 (folate, not folic acid), and B12 (methylcobalamin — the active form) at doses optimized for cellular energy metabolism.
