Analysis

NOW Double Strength 5-HTP 200 mg (120 servings) builds on the strengths of its smaller counterpart by offering a highly effective blend of 5-HTP, Niacinamide, and Glycine for mental well-being and sleep support. 5-HTP serves as a crucial building block for serotonin, influencing mood stability and healthy sleep patterns. Niacinamide contributes to metabolic and nervous system health, while Glycine enhances calmness and sleep quality. This product is well-regarded in online reviews and aligns with nutritionist recommendations for addressing mood and sleep concerns, presenting a synergistic formula at a particularly attractive price point.

Pros
  • Offers a potent and well-chosen dose of 5-HTP, a key ingredient for mood and sleep regulation.
  • The synergistic combination with Niacinamide and Glycine enhances overall effectiveness for nervous system support and relaxation.
  • Comes from NOW, a highly respected brand known for rigorous quality control and product integrity.
  • Provides exceptional value per serving, making it economical for regular, long-term use.
Cons
  • Some of the listed health goals, such as Vision Support and Digestive Health, are not directly addressed by the product's ingredients.
  • The Niacinamide content, while supportive, may not be high enough for individuals seeking therapeutic doses for specific Niacin-related conditions.
  • The collection 'Taurine' is listed, but the ingredient itself is absent from the product's formulation, which could cause confusion.

Categories
5-HTP 95.0
At 200mg of 5-HTP from Griffonia simplicifolia, this product provides a robust and highly effective dose for its intended purpose of supporting serotonin production, mood, and sleep.
Niacin 70.0
The product includes 20mg of Niacin as Niacinamide, a standard dose that contributes to daily nutritional requirements and metabolic function. It's a good supportive amount but not a high therapeutic dose.
Glycine 70.0
The 100mg of Glycine provides a beneficial amount that can aid in calming and sleep support. While effective, some studies use higher doses (e.g., 3000mg) for more pronounced sleep effects, suggesting it's a supportive rather than a primary dose.
Goals
Sleep Support 95.0
5-HTP readily converts to serotonin and subsequently to melatonin, the hormone essential for regulating sleep cycles. Glycine also aids sleep by promoting a calming effect and lowering body temperature, making this an excellent formula for sleep support.
Mood Support 95.0
The primary ingredient, 5-HTP, is highly effective for mood support by directly increasing serotonin, a neurotransmitter strongly associated with feelings of well-being, happiness, and emotional stability.
Stress Relief 90.0
By increasing serotonin levels, 5-HTP contributes significantly to mood stability and stress reduction. Glycine further enhances relaxation and calmness by acting as an inhibitory neurotransmitter, making this an effective blend for stress relief.
