17 markers in this category
Active Vitamin B12
Active Vitamin B12 measures the bioavailable B12 your cells can utilise. For active individuals, B12 may support oxygen transport, energy metabolism, and recovery.
Folate (Folic Acid)
Folate measures vitamin B9, a nutrient that may support oxygen-carrying red blood cell production and tissue repair.
Holotranscobalamin
Holotranscobalamin measures the earliest sign of B12 depletion. For active individuals, catching B12 deficiency early may help maintain red blood cell production, oxygen transport, and optimal recovery from intense training.
Intrinsic Factor Antibodies
Intrinsic Factor Antibodies tests for autoimmune B12 malabsorption.
Methylmalonic Acid (MMA) (Blood)
MMA Blood measures functional B12 activity at the cellular level.
Methylmalonic Acid (MMA) (Urine)
MMA Urine is a non-invasive functional B12 assessment.
Vitamin A
Vitamin A measures retinol, a fat-soluble vitamin that may support physical performance through its role in immune function, vision, and tissue repair.
Vitamin B1 (Thiamine)
Vitamin B1 (thiamine) is considered essential for converting carbohydrates into energy during exercise. Active individuals may have higher requirements due to increased metabolic demands.
Vitamin B12
Vitamin B12 is considered important for oxygen transport via red blood cells and energy metabolism during exercise. Active individuals may have increased requirements.
Vitamin B2 (Riboflavin)
Vitamin B2 (riboflavin) is considered essential for energy metabolism and antioxidant defence during intense physical activity. Active individuals may have increased requirements.
Vitamin B3 (Niacin)
Vitamin B3 (niacin) is considered a key precursor to NAD+, which may support energy production and cellular recovery during physical training. Active individuals may have increased metabolic demands for niacin.
Vitamin B6
Vitamin B6 is considered essential for amino acid metabolism during exercise, which may directly support muscle protein synthesis and recovery. Active individuals may have increased requirements.
Vitamin B7 (Biotin)
Vitamin B7 (biotin) is considered important for macronutrient metabolism during physical performance. It may support efficient energy utilisation from fats, proteins, and carbohydrates.
Vitamin C
Vitamin C is considered a critical antioxidant for active individuals, potentially supporting immune function during intense training and aiding tissue repair and recovery.
Vitamin D (25-OH)
Your vitamin D level tells you how much vitamin D your body has in store, and that store drops between October and March, exactly the months when your training load peaks.
Vitamin E
Vitamin E is a powerful antioxidant that may support exercise recovery by reducing oxidative stress from intense training. Monitoring levels can help optimise your recovery strategy.
Vitamin K1
Vitamin K1 supports bone mineralisation and blood clotting — both essential for active individuals. Adequate levels may help reduce fracture risk and support recovery from training.
