Energy density in breastmilk is primarily driven by fat content. Nutrient-dense foods such as avocados, nut butters, whole grains, and lean proteins are associated with well-balanced caloric output in breastmilk.

Total Fat
Optimal
4.3 g / 100 mL
Reference 2.5–6.0 g  ·  Optimal zone 3.5–4.5 g
2.5 g6.0 g

Total fat varies naturally across a feeding — hindmilk is notably richer in fat than foremilk. Diets emphasising healthy fats from olive oil, avocados, nuts, and fatty fish are associated with a favorable fat profile.

Protein
Slightly Low
0.88 g / 100 mL
Reference 0.7–1.5 g  ·  Optimal zone 0.9–1.2 g
0.7 g1.5 g

Protein-rich foods such as lean meats, eggs, fish, legumes, and Greek yogurt are associated with higher protein concentrations in breastmilk. A total daily protein intake of 70 g or more is generally linked to optimal milk protein levels during lactation.

Carbohydrates / Lactose
Optimal
7.2 g / 100 mL
Reference 5.8–8.2 g  ·  Optimal zone 6.5–7.5 g
5.8 g8.2 g

Lactose is the primary carbohydrate in breastmilk and remains relatively stable regardless of maternal diet. Adequate daily hydration and overall caloric intake are most closely associated with consistent lactose production.

Cow's Milk Proteins  ·  Detected
Dairy proteins consumed by the mother are known to pass into breastmilk. Some infants may show sensitivity through signs such as persistent fussiness, skin rash, or digestive discomfort. If these signs are present, discussing dietary adjustments with a pediatrician is commonly recommended.
Peanut Proteins  ·  Trace Detected
Peanut proteins can appear in breastmilk following dietary consumption. Current research suggests early, low-level peanut exposure through breastmilk may support immune tolerance development in some infants, though individual responses vary. Discussing peanut exposure with a pediatric provider is commonly suggested.
Fatty Acid Profile
DHA (Omega-3)
Optimal
17.4 mg / 100 mL
Reference 5–35 mg  ·  Optimal zone 15–30 mg
5 mg35 mg

DHA levels consistent with a diet that includes omega-3 rich sources. DHA found in fatty fish (salmon, sardines, mackerel) and algae-based supplements is known to support infant neurological and visual development.

Omega-6 : Omega-3 Ratio
Elevated
7.8 : 1
Reference 2:1–15:1  ·  Optimal: below 5:1
2 : 115 : 1

Reducing vegetable oils high in omega-6 (sunflower, corn, soybean oil) while increasing omega-3 sources such as fatty fish, walnuts, flaxseeds, and chia seeds is associated with a more balanced omega-6 to omega-3 ratio in breastmilk.

Fat Composition Breakdown

17%
Saturated  47%  (ref 40–58%)
Monounsaturated  36%  (ref 30–45%)
Polyunsaturated  17%  (ref 12–25%)

All three fat fractions fall within normal reference ranges. A varied diet including fatty fish, olive oil, avocados, and seeds is associated with a balanced polyunsaturated fat profile. Increasing dietary omega-3 intake would also help improve the omega-6 : omega-3 ratio.

Key Micronutrients
Vitamin D
Below Optimal
32 IU / L
Ref 10–120 IU/L  ·  Optimal 50–120
10 IU120 IU

Vitamin D from fatty fish, egg yolks, and fortified dairy is known to influence breastmilk Vitamin D levels. Sun exposure and Vitamin D3 supplementation — discussed with a healthcare provider — are among the most studied approaches for raising breastmilk Vitamin D concentrations.

Vitamin B12
Slightly Low
0.42 μg / L
Ref 0.2–1.2 μg/L  ·  Optimal 0.5–1.0
0.2 μg1.2 μg

B12 is found primarily in animal products — meat, fish, poultry, eggs, and dairy. Plant-based diets are known to produce lower B12 concentrations in breastmilk. A B12 supplement is commonly discussed for those following vegan or vegetarian diets while lactating.

Iron
Optimal
0.41 mg / L
Ref 0.2–0.8 mg/L  ·  Optimal 0.3–0.6
0.2 mg0.8 mg

Iron in breastmilk is highly bioavailable. Its absorption is enhanced by Vitamin C-rich foods. Red meat, lentils, spinach, and fortified cereals are among the foods most associated with healthy iron intake during lactation.

Lifestyle Exposure

Caffeine
Moderate

Not DetectedLowModerate ◀High

Caffeine from coffee, tea, energy drinks, and chocolate is known to pass into breastmilk, with peak concentrations typically appearing 1–2 hours after consumption. The caffeine half-life in young infants is significantly longer than in adults, which is why spacing caffeine intake away from feeding times is a commonly discussed approach.

Alcohol (Ethanol)
Not Detected

No alcohol was detected in this sample. Alcohol is known to pass freely into breastmilk, with concentrations mirroring blood alcohol levels. Waiting approximately 2–3 hours per standard drink before nursing is a widely referenced guideline for minimising infant exposure.
