L-methylfolate : CerefolinNAC
A medical food for the dietary management of neurovascular oxidative stress and/or hyperhomocysteinemia.
L-methylfolate
L-methylfolate in Cerefolin®NAC offers homocysteine protection
L-methylfolate is directly involved in Hcy metabolism.
In a comparison of single dose 5mg L-methylfolate to 5mg folic acid, L-methylfolate was 3X more effective in decreasing plasma homocysteine.
Cerefolin®NAC provides your patients with the superior homocysteine effect of 5mg L-methylfolate.

L-methylfolate in Cerefolin®NAC Offers Superior Bioavailability
Data on file
- 5mg L-methylfolate is 7x more bioavailable than 5mg folic acid.
- The peak concentration (Cmax) of L-methylfolate was higher (129 ng vs 14.1 ng) after 5 mg oral dose L-methylfolate compared to 5 mg oral dose folic acid.
Folic Acid Blocks Transport of L-methylfolate Across the Blood Brain Barrier

- L-methylfolate is 7x more bioavailable than folic acid.
- Cerefolin®NAC contains the active form of folate (L-methyfolate) that crosses the blood brain barrier and is immediately used by the brain to
- reduce homocysteine and oxidative stress
- normalize acetylcholine
2 out of 3 cognitively impaired patients may have a compromised ability to get folate into the brain
Early memory loss patients have low Cerebral Spinal Fluid (CSF) levels of folate. L-methylfolate in Cerefolin®NAC provides the nutritional requirements to increase folate levels in the brain.4 Patients with the MTHFR polymorphism and elevated homocysteine, particularly when associated with low serum folate levels, are 6X more likely to develop progressive memory loss.1

Due to the MTHFR polymorphism, 2 out of 3 memory impaired patients have a distinct need to get L-methylfolate into the brain. 2
L-methylfolate in Cerefolin®NAC is the only form of folate used by the brain3

- L-methylfolate is unaffected by the CT/TT genotypes of MTHFR.
- No conversion is required with L-methylfolate.
- Cerefolin®NAC contains L-methylfolate, the active form of folate, to:
- reduce homocysteine and oxidative stress
- support the synthesis of acetylcholine
