3 Documented Benefits
2/5 Evidence Score

FenuKale™ Nu is Mibelle's oral blend of blue fenugreek (Trigonella caerulea) and kale (Brassica oleracea), a polyphenol/flavonoid-rich extract marketed for skin protection against pollution via Nrf2-mediated detox signaling. Its branded trial was placebo-controlled in a high-pollution Mumbai cohort and reported improved skin moisture and reduced water loss. Honest framing: one manufacturer-associated trial; the broader fenugreek and cruciferous-vegetable literature supports the antioxidant rationale.

Studied Dose Branded skin trial: 350 mg/day for 56 days. Taken as a capsule.
Active Compound Polyphenol and flavonoid blend from blue fenugreek (Trigonella caerulea) and kale (Brassica oleracea), spray-dried. FenuKale™ Nu is manufactured by Mibelle Biochemistry.

Benefits

Skin moisture and barrier in a polluted environment (branded RCT)

In a placebo-controlled trial in a high-pollution city, oral FenuKale (350 mg/day) increased skin moisture and reduced transepidermal water loss versus placebo. One manufacturer-associated study.

Supported by Trial 1

Nrf2-pathway antioxidant / pollution-detox support

The blend is designed to activate Nrf2, the master switch for the body's antioxidant and detoxification enzymes, helping skin cope with oxidative pollution stress.

Supported by Trial 1

Cruciferous and fenugreek polyphenol antioxidant intake

Kale and fenugreek contribute glucosinolate-derived and flavonoid antioxidants, consistent with general antioxidant and skin-from-within support.

Supported by Trial 1

Mechanism of action

1

Nrf2 activation

Polyphenols and kale-derived isothiocyanate precursors induce Nrf2-regulated antioxidant and phase-II detox enzymes, the proposed route to pollution protection.

2

Antioxidant scavenging

Fenugreek and kale flavonoids directly neutralize reactive oxygen species generated by UV and airborne pollutants in skin.

Clinical trials

1
Blue Fenugreek Kale Skin RCT (high-pollution cohort)

Placebo-controlled trial, oral 350 mg/day for 56 days (Clinical, Cosmetic and Investigational Dermatology, 2022).

Adults in a high-pollution urban (Mumbai) environment

Improved skin moisture and reduced transepidermal water loss versus placebo. Manufacturer-associated.

Side effects and drug interactions

Common Potential side effects

Generally well tolerated; both plants are foods.
Mild gastrointestinal upset possible.
Fenugreek can cause a maple-like body odor at higher intakes and may not suit those with legume/fenugreek allergy.
Pregnancy: fenugreek in larger amounts is traditionally uterine-active, so precautionary avoidance of concentrated extracts is reasonable.

Important Drug interactions

Antidiabetic medications: fenugreek can lower blood glucose; monitor for additive effects.
Anticoagulants: fenugreek has theoretical mild antiplatelet activity.
Thyroid/iodine: very high cruciferous intake is goitrogenic in theory, not a concern at supplement doses.
