Why it matters
Key nutrients in Kefir
Lactobacillus & Bifidobacterium
10โ30 billion CFU
Support the estrobolome: the gut bacteria that metabolise oestrogen. Key for oestrogen-dominant conditions.
Calcium
120mg / 100ml
Clinically reduces PMS severity.
B12
0.48mcg / 100ml
Red blood cell production and energy.
Vitamin K2
Significant
Bone density: directs calcium to bones rather than arteries.
Cycle nutrition
When Kefir is most valuable
The gut microbiome directly affects how oestrogen is metabolised and recycled. Kefir's probiotic profile supports healthy oestrogen clearance in the follicular phase, and calcium reduces PMS symptoms in the luteal phase.

How to track Kefir accurately
"250ml kefir" or "1 glass of kefir" are both accurate entries. Specify full-fat vs low-fat. Flavoured kefir adds significant sugar: log plain kefir and track any additions separately.
