D, L-Phenylalanine, 500 mg, 100 Vegetarian Capsules

Life Extension's D, L-Phenylalanine capsules have been very effective for me. The ingredients include D, L-Phenylalanine, which supports mood and cognitive function. The capsules are vegetarian and easy to swallow. I've noticed improvements in my mood and mental clarity since I started taking them. The quality is excellent, and the packaging is convenient with a secure lid. They are definitely worth buying for anyone looking to support their mental well-being.

I can feel the difference in my baseline mood and motivation on a day-to-day basis. It's subtle but quite noticeable. For those who are wondering my "good mood" supplement stacks consist of magnesium bisglycinate, l-tyrosine, d,l-phenylalanine, and l- theanine. So far it works pretty well in terms of increasing my productivity definitely a money well spent.

Do phenylalanine is an amino acid that works well for deoression and stress. I pair this with 5 HTP and lithium orotate and this is a great combo to keep me from slumping back in the blues. Highly recommend!

Great product for ADHD symptoms (and even depression, I have heard). Helps to keep concentration and energy level in good shape whole day. Beneficial product. Great quality. No taste.

I've been using Life Extension D, L-Phenylalanine for a few weeks, and it's been a great addition to my routine. It helps support my mood and focus without causing any jitters. I feel more balanced and clear-headed throughout the day. Highly recommend it for anyone looking to support their cognitive health.

I found it really helpful during times when I’ve been in an emotional low, especially related to perimenopause. It gives me a gentle lift in mood and helps me feel more balanced and motivated throughout the day.

All the indicators suggest that i should have reaped massive benefit from this particular supplement, but i don't remember ever having taken them (Have since run out and am writing this almost a year after purchasing) maybe i'll restock to double check

Something about this ingredient seems to have a detrimental effect on my energy. I used to take it in the morning with my Stimulants, and at first it worked well but eventually I started becoming severely fatigued in the evening or late afternoon. Could just be the combination of this and my stimulants, though.

What Is D, L-Phenylalanine Capsules? Phenylalanine is an essential amino acid, which means your body can’t produce sufficient amounts and requires it from an external source. It’s converted to L-tyrosine in the liver, which is then converted into dopamine, norepinephrine and epinephrine (adrenaline) hormones that can become depleted for a variety of reasons. Replenishing norepinephrine in the brain can support brain health. The neurotransmitters produced from phenylalanine supplementation bring a wide range of cognitive health benefits. D, L-Phenylalanine Benefits Supports production of L-tyrosine, which is used to make dopamine, norepinephrine & epinephrine Helps promote healthy mood & sleep Supports healthy cognitive function Provides protection for brain cells

I have ADHD and CFS and find this supplement is great for boosting energy levels and helping me to stay focussed on tasks for longer. I trust Life Extension as a quality brand in the supplement market.
