Analysis

Source Naturals is a long-standing and respected brand known for its commitment to holistic health, with the 'Serene Science' line specifically targeting mood and stress. This 5-HTP product delivers a robust 100mg dose derived from Griffonia simplicifolia. A significant advantage is its exceptional price per serving (19 cents) for a large 120-count bottle, making it one of the best value options for a pure 5-HTP supplement. While it focuses solely on 5-HTP without the addition of Vitamin B6 (which enhances conversion to serotonin), its purity, effective dosage, and cost-effectiveness make it a highly attractive option for consistent, long-term use, backed by generally positive online reviews.

Pros
  • From a reputable and long-standing brand, Source Naturals, with a dedicated 'Serene Science' line.
  • Provides a standard and effective 100mg dose of 5-HTP.
  • Excellent price per serving (19 cents) for a large 120-count bottle, offering superb value.
  • Derived from Griffonia simplicifolia, a recognized natural source.
Cons
  • Does not include Vitamin B6, which enhances 5-HTP conversion to serotonin.
  • Lower review count compared to some mega-popular alternatives, though still respectable.
Warnings
  • Consult a healthcare professional before use if pregnant, nursing, taking medications (especially antidepressants), or have a medical condition due to potential interactions.
  • May cause drowsiness; use caution when driving or operating machinery after taking.

Goals
Mood Support 82.0
As a precursor to serotonin, 100mg of 5-HTP is a good dose for supporting a balanced mood, and the 'Serene Science' line reflects its targeted purpose. While effective, the lack of Vitamin B6 might mean the body's conversion of 5-HTP to serotonin isn't as efficient for some.
Stress Relief 80.0
The 100mg dosage of 5-HTP is a well-established and generally effective amount for supporting serotonin levels, thus aiding in stress relief. This product provides a direct approach to addressing stress, with its competitive pricing allowing for consistent use.
Sleep Support 80.0
The 100mg dose is suitable for aiding sleep, as serotonin converts to melatonin. This product's excellent price per serving for a 120-count bottle makes it a highly cost-effective option for regular nighttime use to support sleep onset and quality.
