5-HTP

Overview

5-Hydroxytryptophan (5-HTP) is a naturally occurring amino acid and a direct precursor to serotonin, a critical neurotransmitter responsible for regulating mood, sleep, and appetite. Known for its ability to promote emotional balance and enhance overall well-being, 5-HTP has become a popular supplement for managing stress, sleep disturbances, and mild depressive symptoms.

Derived primarily from the seeds of the African plant Griffonia simplicifolia, 5-HTP offers a natural way to support healthy serotonin levels, contributing to improved mental and emotional health.

Other Common Names

Oxitriptan
L-5-HTP

Top Benefits

Reduces stress and anxiety
Supports appetite regulation and weight management

What Is 5-HTP?

5-HTP is a direct precursor to serotonin, synthesized naturally in the body from the amino acid tryptophan. Serotonin plays a central role in mood regulation, relaxation, and the sleep-wake cycle. Low serotonin levels are often linked to stress, anxiety, depression, and sleep disorders.

Supplementation with 5-HTP helps bridge the gap between dietary tryptophan intake and serotonin production. By bypassing several metabolic steps, 5-HTP offers a more direct path to boosting serotonin levels, making it an effe

ctive tool for enhancing mental and emotional well-being.

Extracted from the seeds of Griffonia simplicifolia, a plant native to West Africa, 5-HTP is a potent yet natural solution for improving mood, reducing stress, and supporting restful sleep.

Marco’s Grounds™ 5-HTP Sourcing

At Marco’s Grounds™, our 5-Hydroxytryptophan (5-HTP) is sourced from a family-owned farm in West Africa, where Griffonia simplicifolia grows naturally in nutrient-rich soils.

Using a meticulous extraction process, we derive 5-HTP directly from the plant’s seeds — preserving its purity and potency. This natural approach ensures a clean, bioavailable form that supports serotonin production, emotional balance, and restful sleep with every dose.

5-HTP Dosing Principles and Rationale

Clinical studies suggest effective doses of 5-HTP range from 50 to 300 mg daily, depending on individual needs and health goals. Marco’s Grounds™ applies hormetic dosing principles (see Marco’s Grounds Dosing Philosophy), ensuring that each dose delivers maximum benefits without disrupting the body’s natural equilibrium.

For mood enhancement and stress relief, 5-HTP is best taken in divided doses throughout the day.
For sleep support, it is most effective when taken 30–60 minutes before bedtime.

5-HTP Key Mechanisms

1. Mood Support

Increases serotonin production in the brain, enhancing emotional balance and reducing symptoms of mild depression [1].
Modulates stress responses and mitigates anxiety via serotonergic pathways [2].

2. Sleep Enhancement

Boosts melatonin synthesis by increasing serotonin availability, promoting better sleep quality and duration [3].
Shortens sleep latency (time to fall asleep) and reduces nighttime awakenings [4].

3. Appetite Regulation and Weight Management

Supports appetite control by acting on the hypothalamus, reducing hunger and food intake [5].
Helps reduce stress-induced overeating, aiding healthy weight management [6].

4. Neuroprotective Properties

Provides antioxidant activity that protects neurons from oxidative stress and inflammation, supporting long-term brain health [7].
