Supports collagen synthesis and wound healing and improves non-haem iron absorption.
Supports DNA synthesis and red-blood-cell production and works closely with B12.
Supports red-blood-cell formation, DNA synthesis, and the nervous system.
Regulates calcium and phosphate and supports bone and muscle function. Test status when clinically indicated.
Supports extracellular fluid balance, nerve impulses, and contraction; needs rise with heavy sweating.
Regulates intracellular fluid balance, nerve signals, and muscle contraction.
Supports bone structure, muscle contraction, nerve signalling, and blood clotting.
Helps ATP use, nerve and muscle function, and bone health. High supplemental doses may cause diarrhoea.
Supports antioxidant enzymes and thyroid-hormone metabolism. Excess intake is toxic.
Needed to make thyroid hormones that regulate metabolism, growth, temperature, and energy.
Supports iron metabolism, connective tissue, antioxidant enzymes, and the nervous system.
Supports enzymes, protein synthesis, immunity, and wound healing. Avoid chronic high-dose supplementation.
Supports haemoglobin, myoglobin, oxygen transport, and energy enzymes. Vitamin C improves plant-iron absorption.
Supports circulation, temperature control, and transport. Drink regularly and adjust for heat and sweat.
Supports bowel function, satiety, and the gut microbiome. Eat varied plants and increase gradually.
Provides energy, essential fatty acids, and supports absorption of vitamins A, D, E, and K.
Supplies glucose and glycogen for harder and longer training. Adjust intake to activity.
Provides amino acids for muscle and tissue repair. Include a meaningful source at several meals.
