Biomarkers, explained
Each guide covers one result from the Holohabits panel: what it measures, what a low or high number indicates, and which changes to diet, sleep or supplementation actually move it. The reference ranges shown are the ones your report uses.

Markers on the panel
DHA (C22:6 n-3)The omega-3 that makes up the structure of brain and retinal tissue.Fatty acids
DHA to EPA ratioHow your two long-chain omega-3s sit relative to each other.Fatty acids
EPA (C20:5 n-3)The omega-3 most closely tied to inflammatory signalling and mood.Fatty acids
Linoleic acid (LA)The omega-6 fat that seed oils supply in far larger amounts than the body was built for.Fatty acids
Oleic acidThe monounsaturated fat that dominates olive oil and much of your own body fat.Fatty acids
Omega-3 IndexThe share of your red blood cell membranes made up of the omega-3 fats EPA and DHA.Fatty acids
Omega-6 to omega-3 ratioLinoleic acid measured against your combined EPA and DHA.Fatty acids
Active vitamin B12The fraction of vitamin B12 your cells can actually take up and use.Vitamins
Total Vitamin DThe circulating store of vitamin D, built from sunlight on skin and from what you eat.Vitamins
Vitamin A (Retinol)The preformed vitamin A your eyes, immune system and skin depend on.Vitamins
Vitamin E (Alpha-tocopherol)The main fat-soluble antioxidant guarding your cell membranes from oxidation.Vitamins
CopperA trace mineral your body needs for iron transport, collagen and nerve function.Minerals
Copper:Zinc ratioThe balance between two minerals that compete for the same absorption pathway.Minerals
FerritinThe protein that stores iron, and the best single indicator of how much iron you have banked.Minerals
Magnesium (erythrocytes)Magnesium measured inside red blood cells, where most of the body's supply actually sits.Longevity
NAD+The coenzyme every cell uses to turn fuel into energy and to repair DNA.Longevity
Selenium (erythrocytes)A trace mineral your thyroid and antioxidant enzymes cannot work without.Longevity
Zinc (erythrocytes)Zinc measured inside red blood cells, a steadier read than serum zinc.Longevity
CortisolThe main stress hormone, and the one that sets your daily energy rhythm.Hormones
Testosterone/Cortisol ratioThe balance between the hormone that builds tissue and the one that breaks it down.Hormones
Total TestosteroneThe full circulating amount of testosterone, both bound and free.Hormones
ArginineThe amino acid your blood vessels use to make nitric oxide.Amino acids
AsparagineA non-essential amino acid your liver makes, used in nerve function and nitrogen transport.Amino acids
BCAA to tyrosine ratioMuscle-building amino acids measured against the dopamine precursor.Amino acids
Branched-chain amino acids (BCAA)Leucine, isoleucine and valine, the three amino acids muscle burns and builds with.Amino acids
CarnitineThe shuttle that carries fatty acids into mitochondria to be burned for energy.Amino acids
CitrullineThe amino acid that converts to arginine and drives blood flow during exercise.Amino acids
GlutamineThe most abundant amino acid in your blood, and the main fuel for gut and immune cells.Amino acids
Glutamine to proline ratioGut-lining fuel measured against connective tissue repair material.Amino acids
ProlineThe amino acid that gives collagen its structure, and therefore your skin, joints and blood vessels.Amino acids
TaurineA sulphur amino acid concentrated in heart, muscle and nerve tissue.Amino acids
ThreonineThe essential amino acid your gut uses to build its protective mucus layer.Amino acids
TryptophanThe essential amino acid your body turns into serotonin and melatonin.Amino acids
Tryptophan to tyrosine ratioThe serotonin precursor measured against the dopamine precursor.Amino acids
TyrosineThe amino acid behind dopamine, noradrenaline and thyroid hormone.Amino acids
ValineOne of the three branched-chain amino acids, used in muscle repair and nitrogen balance.Amino acids
