Description

CDP-Choline, also known as citicoline, is a naturally occurring compound found in every cell in the body. Unlike simple choline supplements, citicoline provides two distinct active components: choline, which supports acetylcholine production, and cytidine, which converts to uridine, supporting normal brain cell membrane components.*

Double Wood's CDP-Choline delivers 300mg per capsule. Best taken in the morning or early afternoon; if you're sensitive to taking supplements later in the day, consider morning use. Every batch tested. Third-party tests by ISO/IEC 17025 accredited labs. COAs published openly. For those building a complete morning cognitive routine, CDP-Choline pairs naturally with Lion's Mane. CDP-Choline supports mental clarity and attention, while Lion's Mane supports broader brain health, as part of a well-rounded cognitive wellness routine.*

Benefits
  • Choline and cytidine, two active components in a single capsule. Unlike simple choline sources, citicoline delivers both choline (for acetylcholine production) and cytidine (which converts to uridine, supporting normal brain cell membrane components).*
  • Supports mental clarity, attention, and cognitive performance.*
  • 300mg per capsule in a straightforward daily format, manufactured in a cGMP-certified USA facility.
  • Commonly paired with Lion's Mane. CDP-Choline supports mental clarity and attention, while Lion's Mane supports broader brain health, a two-part morning cognitive routine.*
  • Every batch tested. Third-party tests by ISO/IEC 17025 accredited labs. COAs published openly.

Directions & Dosage

Take one capsule once or twice daily, preferably in the morning or early afternoon. Can be taken with or without food. If you're sensitive to taking supplements later in the day, consider morning use. Consult your healthcare provider for personalized guidance on serving size and timing.

The Science Behind CDP-Choline (Citicoline)

Attention and Cognitive Performance

Citicoline provides choline, a nutrient involved in acetylcholine production, which plays a role in normal cognitive function. Citicoline has been evaluated in clinical research, including randomized controlled designs, across various doses and populations. One such trial, by Nakazaki et al., using Cognizin-brand citicoline at a 500mg daily dose, examined healthy adults with poor sustained attention over 12 weeks. This trial has been presented at a scientific symposium; we'll update this section if and when it's published in a peer-reviewed journal. Double Wood's capsule provides 300mg, a different dose than the one studied.

Choline and Cytidine, Two Pathways

Choline is a nutrient involved in acetylcholine production, which plays a role in normal cognitive function. Cytidine, the second component citicoline provides, is converted to uridine in the body, involved in supporting normal brain cell membrane components. This two-component profile is what distinguishes citicoline from single-pathway choline sources like Alpha GPC or choline bitartrate.*

Benefits

CDP-Choline (Citicoline)

CDP-Choline (cytidine diphosphocholine, also called citicoline) is a naturally occurring phospholipid intermediate found in every cell in the body. When consumed as a supplement, it is cleaved in the gut into choline and cytidine. Choline is absorbed and used to synthesize acetylcholine, a neurotransmitter involved in attention and cognitive function, and supports normal brain cell membrane components. Cytidine is converted to uridine in the body, which plays a role in supporting normal brain cell membrane components. This dual-component profile distinguishes citicoline from simpler choline supplements.* Every batch tested for purity, potency, heavy metals, and microbial safety.

Frequently Asked Questions

What is CDP-Choline (citicoline) and what does it do?

CDP-Choline (citicoline) is a naturally occurring compound that provides both choline and cytidine when absorbed. Choline supports acetylcholine production, while cytidine converts to uridine, supporting normal brain cell membrane components. Together, these components support mental clarity, attention, and cognitive performance.* Double Wood's formula delivers 300mg per capsule.

What is the difference between CDP-Choline and Alpha GPC?

Both are bioavailable choline compounds, but they work through different pathways. Citicoline provides choline plus cytidine, supporting both acetylcholine production and normal brain cell membrane components via the uridine pathway. Alpha GPC provides choline bound to glycerophosphate, supporting acetylcholine production without the cytidine component. For most people, one or the other is sufficient as a primary choline source.

How much CDP-Choline should I take per day and when?

Double Wood CDP-Choline delivers 300mg per capsule. Take one capsule in the morning or early afternoon as part of a consistent daily cognitive routine. If you're sensitive to taking supplements later in the day, consider morning use. Consult your healthcare provider for personalized guidance.

Can you take CDP-Choline every day?

CDP-Choline is designed for consistent daily use as part of a morning cognitive wellness routine. It is generally well-tolerated for daily use at recommended serving sizes.

What supplements pair well with CDP-Choline?

CDP-Choline pairs naturally with Lion's Mane as a complementary morning cognitive routine. CDP-Choline supports mental clarity and attention, while Lion's Mane supports broader brain health, together as part of a daily cognitive routine.*

Is CDP-Choline safe, and are there any side effects?

CDP-Choline is generally well-tolerated at recommended serving sizes. Mild headache, digestive discomfort, or a sense of heightened alertness may occur in some individuals. Avoid taking late in the day if you are sensitive to sleep disruption. Those who are pregnant, nursing, or taking prescription medications, particularly medications affecting acetylcholine or dopamine systems, should consult their healthcare provider before use.

Is Double Wood CDP-Choline third-party tested, and where can I find the COA?

Every batch tested. Third-party tests by ISO/IEC 17025 accredited labs. COAs published openly. Testing verifies identity, potency, heavy metals by ICP-MS, and a full microbial panel. The Certificate of Analysis is publicly available on this product page and searchable by lot number, no request required.

Excellent company

"I ordered the CDP Choline bundle and based on pricing of other supplement companies Double Wood had by far the best prices. Plus, i received my supplements in two days and in eco-friendly packaging! i also appreciate that they post the lab report to verify potency on their website. As for the choline, I’ve only been taking for a couple weeks but i can honestly say that my recall seems to be better. I’ll buy all my supplements from Double Wood henceforth."
