Active Folate Crosses the Blood-Brain Barrier to Work in the Brain
The active folate found in DEPLIN®, L-methylfolate, crosses the blood-brain barrier and is thought to help enhance production of the neurotransmitters required by many patients to help achieve and maintain the benefits of antidepressants.1-6
- L-methylfolate is the biologically active form of folate and is involved in neurotransmitter synthesis. L-methylfolate modulates the synthesis of monoamines1,2,4
- It assists in the formation of the enzyme co-factor BH4, also known as tetrahydrobiopterin
- BH4 activates the rate-limiting enzymes tryptophan hydroxylase and tyrosine hydroxylase for monoamine synthesis
- Activation of tryptophan hydroxylase initiates a cascade that leads to the synthesis of serotonin, and
- Activation of tyrosine hydroxylase initiates a cascade that leads to the synthesis of dopamine and norepinephrine
- The addition of L-methylfolate may boost monoamine synthesis and help to manage depression by augmenting the therapeutic benefits of antidepressants4
Have confidence knowing DEPLIN® can be safely
added to patients’ current therapy.
