Description
Product Overview
Life Extension D, L-Phenylalanine is a well-formulated dietary supplement delivering 500 mg of the essential amino acid phenylalanine per capsule. The product comes in convenient capsules, making it easy to integrate into your daily routine. Life Extension is a brand with a long history of developing products based on rigorous scientific research and strict quality standards. The company was founded with the goal of offering supplements that support the body's natural functions in a transparent and reliable way, and their commitment to purity and efficacy has made them a respected name in the health industry.
By combining the D- and L-forms of phenylalanine, this supplement offers a balanced amino acid important for several bodily processes. Phenylalanine is essential, meaning the body cannot produce it itself and requires intake through diet or supplements. Life Extension's product is also free from gluten and genetically modified ingredients, reflecting their focus on pure and safe raw materials.
Active Ingredients 26 Science
The active ingredient in this product is D, L-phenylalanine, an amino acid that plays a central role in the body's biochemistry. L-phenylalanine is the natural form that the body can convert into tyrosine, another amino acid that is a building block for several important neurotransmitters in the nervous system. D-phenylalanine is its mirror-image isomer and contributes unique properties that complement the L-form. Together they provide a synergistic effect that may be beneficial for normal mental function and well-being.
Benefits 26 Uses
- Support for mental clarity and focus: Individuals looking to maintain or improve their concentration may benefit from regular intake.
- Contributes to normal mood: Phenylalanine is a building block for neurotransmitters such as dopamine, which are important for our well-being.
- Suitable for active lifestyles: For those with a busy schedule needing to maintain mental sharpness throughout the day.
- Complements a protein-rich diet: Especially relevant for people who have difficulty obtaining sufficient amino acids through diet, such as vegetarians or older adults.
- Practical form: The capsules are easy to dose and suitable as a daily supplement in combination with other nutritional products.
Usage 26 Dosage
The recommended dose is one capsule per day, providing 500 mg of D, L-Phenylalanine. It can be taken with a meal for better absorption and to reduce potential stomach irritation. Some choose to take the supplement in the morning to support daily activities, but it can be adjusted according to individual needs. For optimal effect, the product can be combined with other amino acids or nutrients that support cognitive health, but it is always advisable to consult healthcare professionals if uncertain.
Quality 26 Manufacturing
Life Extension has a solid quality philosophy that permeates the entire production chain. The supplement is manufactured under strictly controlled conditions with a focus on purity and safety. The products undergo regular testing to ensure they are free from unwanted substances and meet high standards regarding content and dosage.
