Improves Sleep Quality

L-Ornithine HCl has been reported to improve sleep quality, specifically the sensation of having slept longer. In clinical studies, participants taking L-Ornithine HCl for 5 weeks showed significant improvement in sleep duration scores compared to placebo. This supports better rest without drowsiness the next day.

Systematic Review Completed

Reduces Morning Fatigue

Crocin, derived from gardenia fruit, has been reported to reduce fatigue upon waking. In a randomized, double-blind crossover study with adults aged 35-60, participants taking 7.5mg of crocin for 2 weeks showed improved fatigue recovery scores compared to control group.

Research-backed Ingredients

4

Comprehensive Vitamin B Support

Includes Vitamin B1 (15mg), B2 (6mg), and B6 (10mg) plus Inositol (40mg) to support energy metabolism. These essential B-vitamins complement the functional ingredients for overall wellness support throughout the day.

Nutritional Support

L-Ornithine HCl for Sleep Quality

L-Ornithine HCl dissolves in water to become L-Ornithine, an amino acid that supports sleep quality.

Research shows it improves:

The sensation of sleeping longer
Better mood upon waking

Each daily serving provides the equivalent of approximately 900 shijimi clams worth of ornithine (produced via fermentation).

Crocin for Fatigue Relief

Crocin (crocetin) is a yellow pigment found in gardenia fruit and saffron, related to beta-carotene and lycopene.

It has been reported to reduce fatigue upon waking. The systematic review of crocin research confirms its effects on morning fatigue reduction.

Sleep + Fatigue Recovery Cycle

Sleep is naturally when your body should recover from fatigue. FANCL noticed that many people still feel tired upon waking, despite adequate sleep hours.

Quality sleep is essential for fatigue relief. This supplement addresses both factors: improving sleep quality AND reducing morning fatigue.
