What it does

Supports gut health & digestion

Three complementary probiotic strains help balance the gut microbiome and support healthy digestion.

Brighter, clearer, healthier-looking skin

Targets the gut–skin axis with strains known to support skin health, plus zinc for visible clarity.

Better mood & more stable energy

Bioavailable B vitamins support mental clarity, focus and steady energy throughout the day.

Strong immune support

Vitamins D3, K2 and zinc work together to support natural immunity and overall health.

Sleep deeper, naturally

BeTheanine® and magnesium bisglycinate calm the mind before bed and support high-quality, deeper sleep.

Wake restored, not groggy

Supports overnight skin repair

Antioxidants help your skin recover from pollution, stress and UV exposure accumulated through the day.

The Science Behind our Supplements

Built by a gut–skin science team

Developed collaboratively by experts in microbiome science, nutrition and cosmetic science to support gut health, skin clarity and immune function in two daily capsules.

Multi-strain probiotics chosen for synergy

Three complementary strains — Lpc-37, BI-04 and HN019 — selected for their ability to work together without inhibiting one another, supporting gut comfort, immunity and the gut–skin axis.

Bioavailable vitamins for steady energy & clarity

Highly absorbable B vitamins, Vitamin D3, Vitamin K2 and Zinc Bisglycinate support energy, focus, immunity and skin health throughout the day.

Clinical-grade BeTheanine® for deep, calm sleep

BeTheanine® is our premium L-theanine, 100% derived from decaffeinated green tea, and clinically proven to promote deep, restorative sleep without heavy sedation.

Magnesium bisglycinate for nervous system support

A highly bioavailable form of magnesium that supports the nervous system, eases muscle tension and helps stabilise sleep cycles through the night.

Antioxidant support for overnight skin repair

Polyphenol-rich grape seed extract, copper and selenium help protect cells from oxidative stress, supporting the skin’s natural repair processes while you sleep.

Proven results, by concern

Wrinkle depth decreased by 14 percentage points.

7 person clinical study using medical-grade imaging, 100% used Regime, 2026

Very effective day and night creams - fine lines really reduced. Day and night pills also excellent - a real boost in energy and feeling of well-being, perhaps due to more consistent / better sleep.
