High estrogen is typically defined as “levels exceeding the normal range” for a specific age and menstrual phase, often accompanied by other symptoms (more on this soon), she says.
[10] [15] During normal human pregnancy, estrogen production increases progressively and extremely high estrogen levels are attained. [19] Estradiol levels range from 1,000 to 40,000 pg/mL across pregnancy, [20] are on average 25,000 pg/mL at term, and reach levels as high as 75,000 pg/mL in some women. [21
During the reproductive years of human females, levels of estradiol are somewhat higher than that of estrone, except during the early follicular phase of the menstrual cycle; thus, estradiol may be considered the predominant estrogen during human female reproductive years in terms of absolute serum levels and estrogenic activity.
In a normal adult female, the normal range of estrogen in the luteal phase (when ovulation happens, as well as the vascular tissue preparing for the potential zygote [3]) is 100 pg/ml, in comparison to the proliferative phase (when the uterine lining is thickening [4]) 40-250 pg/ml. [5]
Krill oil capsules. Krill oil is an extract prepared from a species of Antarctic krill, Euphausia superba.Processed krill oil is commonly sold as a dietary supplement.Two components of krill oil are omega-3 fatty acids similar to those in fish oil, and phospholipid-derived fatty acids (PLFA), mainly phosphatidylcholine (alternatively referred to as marine lecithin).

Estradiol is an estrogen, or an agonist of the nuclear estrogen receptors (ERs), the estrogen receptor alpha (ERα) and the estrogen receptor beta (ERβ). [1] [2] [6] In one study, the EC 50 Tooltip half-maximal effective concentration value of estradiol for the human ERα was 50 pM (0.05 nM) and for the human ERβ was 200 pM (0.2 nM).
Levels of estriol increase 1,000-fold during pregnancy, [8] whereas levels of estradiol and estrone increase 100-fold, [12] and estriol accounts for 90% of the estrogens in the urine of pregnant women. [5] At term, the daily production of estriol by the placenta is 35 to 45 mg, [12] and levels in the maternal circulation are 8 to 13 ng/dL. [3]
