Uridine is a powerful cognitive enhancer, a potent neuroprotectant, and a fundamental biological component so important that life can’t exist without it.
URIDINE COMMON NAME
Uridine, Uridine monophosphate, Uridine-5′-monophosphoric acid, UMP, 5′-Uridylic acid.
IN A NUTSHELL
Supports cognitive function
WHAT IS URIDINE?
Uridine is one of the 5 standard nucleosides; the others are adenosine, cytidine, guanosine, and thymidine. These compounds are the building blocks of the main information carrier molecules in the body (DNA and RNA), and play a central role in cellular metabolism. ATP – the “A” standing for adenosine – is known for its role in carrying packets of chemical energy needed for cellular functions. Uridine plays a similar role in two non-ATP high-energy molecules used in a subset of metabolic reactions. Uridine is needed for UTP (made from uridine instead of adenosine) as an activator of substrates in some specific metabolic reactions. Uridine can also be converted into cytidine and support CTP. In this role, it is used for the synthesis of the glycerophospholipids (including phosphatidylcholine in the Kennedy pathway) needed for healthy cell membranes throughout the body and in the brain. And uridine may support different neuroregulatory processes and neurotransmitters. Uridine also crosses the blood brain barrier [1–6]. These structural and functional roles have led to it being used as a nootropic. Uridine is considered to be one of the natural sleep-promoting substances made by the brain, acting via uridine receptors in the areas of the brain which regulate natural sleep [7, 8].
MARCO’S GROUNDS URIDINE SOURCING
Uridine is supplied in a phosphorylated form as Uridine-5′-monophosphoric acid because this form is more stable, helps it get past the digestive system and liver intact, and allows it to cross the blood-brain barrier.
Uridine is Non-GMO and Vegan.
URIDINE DOSING PRINCIPLES AND RATIONALE
One of our dosing principles is to determine whether there is a dosing range, in which many of the benefits occur and above which there appears to be diminishing returns, i.e., a threshold, and to provide a dose within this threshold range (see Marco’s Grounds Dosing Philosophy). We consider uridine to be one of these threshold compounds. Uridine is most commonly used for cognition support. In this functional role, it is common to take a dose of between 150-250 mg. For cognition enhancing purposes, we dose uridine in this range.
