This product offers a convenient blend of L-Tryptophan, Niacinamide, and L-Lysine, highly effective for mood, stress, and sleep support, with secondary benefits for energy metabolism, skin, and immunity. Its main strength lies in the high L-Tryptophan dose.
Life Extension's Optimized Tryptophan Plus is formulated with a synergistic blend of L-Tryptophan, Niacinamide, and L-Lysine, aiming to support a broad spectrum of health goals. The high dose of L-Tryptophan (1000mg) is a key feature, making it particularly effective for enhancing mood, reducing stress, and improving sleep quality by supporting serotonin and melatonin production. Niacinamide, an essential B vitamin, contributes to metabolic processes and nervous system health, while L-Lysine, an essential amino acid, plays a role in protein synthesis and immune function. Online reviews generally reflect user satisfaction, particularly regarding its calming and sleep-enhancing effects. However, while comprehensive, the dosages of Niacinamide and L-Lysine are moderate, meaning for specific needs in those areas, standalone supplements might be more targeted.
- Provides a high and effective dose of L-Tryptophan, strongly supporting mood, stress relief, and sleep.
- Includes Niacinamide and L-Lysine, offering synergistic benefits and convenience in a single supplement.
- Generally positive online reviews indicate user satisfaction with its primary effects.
- The dosages of L-Lysine are relatively modest compared to standalone L-Lysine supplements, potentially not sufficient for higher therapeutic needs.
- Some of the broader health goals, such as Heart Health and Hair Health, are not as robustly addressed by the specific ingredients and their forms in this product.

The 1000mg dose of L-Tryptophan is substantial and effective, making it a core strength of this product for supporting mood, relaxation, and sleep.
Niacin 70.0
Provides a good supporting dose of Niacinamide, which is well-tolerated and useful for various metabolic processes and nervous system support. However, it's not a high dose for specific Niacin deficiencies.
Lysine 50.0
The 250mg dose of L-Lysine is relatively low compared to typical standalone supplements (500-1000mg) for specific uses like cold sore prevention. It offers some foundational support but not a potent therapeutic dose.
