LinumLife® (Flaxseed Lignan Extract — IFF)

Linum usitatissimum
Evidence Level
Moderate
1 Clinical Trial
3 Documented Benefits
3/5 Evidence Score

LinumLife® is a flaxseed (Linum usitatissimum) hull extract standardized for lignans, especially SDG (secoisolariciresinol diglucoside). Flax lignans are converted by gut bacteria into enterolignans, plant compounds with mild estrogen-balancing activity, and LinumLife is studied for easing menopausal symptoms.

Studied Dose A standardized daily dose providing a defined amount of SDG lignans.
Active Compound Flaxseed hull extract standardized to lignans, primarily secoisolariciresinol diglucoside (SDG), a precursor to the enterolignans.

Benefits

Menopausal symptom support

In a clinical study, flaxseed hull lignan extract supported relief of menopausal symptoms, offering a plant-based option for hormonal transition.

Supported by Trial 1

Hormone balance

Lignans have mild, balancing activity at estrogen receptors, which may help smooth the hormonal swings of perimenopause and menopause.

Supported by Trial 1

Antioxidant lignans

The lignans and their gut-derived metabolites act as antioxidants, supporting general and hormonal health.

Mechanism of action

1

Enterolignan conversion

Gut bacteria convert SDG into enterolactone and enterodiol, which weakly modulate estrogen receptors and support hormonal balance.

2

Selective estrogenic activity

The enterolignans can act as mild estrogen agonists or antagonists depending on the tissue, helping buffer hormonal fluctuations.
