Your mood on a daily basis is influenced by a number of factors‚ but one of the chief contributors is how your body is functioning and feeling at any given time. There are several ways to help improve your mood as well as any deficiencies that my be present in your body's constitution. One way may be taking an amino acid supplement such as D‚ L-Phenylalanine by Metabolic Maintenance.

This blend supplies two forms of phenylalanine‚ an essential nonpolar amino acid. The L form acts as a precursor to several important processes‚ including the creation of the DNA-encoded amino acid tyrosine‚ which in turn is converted into chemicals such as dopamine‚ norepinephrine (noradrenaline)‚ and epinephrine (adrenaline). The D form of phenylalanine may have a role in blocking a nervous system enzyme that can amplify pain signals‚ preventing a potential breakdown of the brain's natural narcotics. When combined‚ these two forms have the ability to work quickly to support general mood‚ feelings‚ and physical discomforts. D‚ L-Phenylalanine comes in a vegetarian capsule‚ and according to the promise to its consumers by Metabolic Maintenance through Pure Formulas‚ all products are made with pure active ingredients‚ with no fillers‚ binders‚ or preservatives.

Each 60 capsule bottle of D‚ L-Phenylalanine 750mg by Metabolic Maintenance should last for approximately 2 months at the recommended dosage of 1 capsule a day‚ or as recommended by a healthcare professional. This supplement is best taken between meals.

Metabolic Maintenance vitamins and supplements are time-tested and physician-approved. All products are truly excipient-free‚ meaning that they have no fillers like cellulose or silicon dioxide that other manufacturers often add to products. Using only the purest ingredients and cutting-edge medical technologies‚ Metabolic Maintenance vitamins and supplements come in tinted glass bottles to best store them without losing their potency and effectiveness.

      Happy in a bottle

      from Washington on 3/16/2013
      My ND recommended DL-Phenylalanine to me as part of my pre-menopause plan to help with minor mood swings. It has brought me back to the happy calm person I remember! She said if I need them I would feel the difference right away (I did indeed!) and if I didnt I would not feel a change so I had my husband take one as an experiment (he was not experiencing the mood/depression that I was) and he did not notice a thing...


      If you are lacking the amino-acids these pills contain you will notice a mood elevation with in 15min. that lasts all day (at least for me is does). If you dont need them you will not notice any change in mood at all.


      Some people aparently need to take 2 per day at intervals to reach max benifits I only need 1. Go to an MD or a ND 1st to see if thats what they recommend because if you dont need these aminos they will not work for you (duh right?)

      Good Quality and Price

      from NJ on 3/08/2011
      I use D,L-Phenylalanine by Metabolic Maintenance together with LDN/OGF to enhence the production and effect of endorphins and enkephalins. These are proteins which bind to opiate receptor sites in the brain thereby influencing the perception of discomfort. By obstructing the action of this enzyme DPA may extend the life of endorphins and enkephalins and their positive influence on comfort levels. L-Phenylalanine is the precursor to two neurotransmitters that help support an alert state.
