Choline

Why I’m Paying Attention to Citicoline on a Vegan Diet (and Why It Matters More With Hashimoto’s)

I’ve been mostly vegan (with rare vegetarian exceptions that never convinced me) since 2007.

I am vegan for the animals. I simply love animals and don’t want them to be exploited. And there are some other big-picture benefits—higher fiber, more micronutrients from plants, and less reliance on animal products.

But over time, I started digging deeper into nutrients that don’t always get enough attention in plant-based eating patterns.

You know the deal, we always hear about B12 and amino acids, but not so much about iron and certainly nothing about choline.

But choline can be crucial for your health, and more specifically, a form called citicoline (also known as CDP-choline). It’s become a supplement I personally started supplementing DAILY, especially in the context of energy, focus, and Hashimoto.

Choline on a vegan diet: not absent, but often lower

Vegan diets are extremely low on choline.

It’s not accurate to say vegans “lack” choline entirely. The body can get it from foods like soybeans, quinoa, broccoli, peanuts, and legumes. But in practice, many plant-based diets still fall short of optimal intake levels, especially if those foods aren’t eaten in large or consistent amounts. (Truth be told, those quantities can’t be eaten, not for choline, you just won’t get there. If you are vegan and you want choline, you have to supplement.)

Choline is essential for:

  • Acetylcholine production (a key neurotransmitter for memory and focus)
  • Liver function and fat metabolism
  • Cell membrane integrity
  • Methylation processes (important for detox and gene regulation)

Because of these roles, low intake doesn’t always show up immediately—but over time it can feel like brain fog, sluggish cognition, or reduced mental clarity for some people.

Citicoline vs CDP-choline vs choline bitartrate (what’s actually different?)

This part confused me at first, because the names are used interchangeably online.

Citicoline = CDP-choline

These are the same compound.

  • Citicoline is the common supplement name
  • CDP-choline (cytidine diphosphate-choline) is the biochemical name

Once ingested, citicoline breaks down into:

  • Choline
  • Cytidine (which can convert into uridine in the body)

The interesting part is that citicoline doesn’t just dump choline into circulation—it supports brain phospholipid synthesis and may cross the blood-brain barrier more effectively than simpler forms.

Choline bitartrate

This is a more basic, cheaper form of choline.

  • Provides raw choline
  • Less efficient for brain uptake
  • More commonly used for general nutritional supplementation than cognitive support

Think of it as: quantity-focused, not brain-targeted

Why I chose citicoline specifically

For me, the decision came down to function rather than just choline content.

I was more interested in:

  • Mental clarity
  • Focus consistency
  • Neurotransmitter support
  • Brain phospholipid health

Citicoline felt like a better fit because it supports not just choline levels, but also the downstream processes involved in brain cell membrane maintenance and acetylcholine production.

In simple terms: I wasn’t just trying to “add choline”—I was trying to support brain chemistry more holistically.

Where Hashimoto’s comes into the picture

Hashimoto’s thyroiditis is an autoimmune condition affecting the thyroid, and it often comes with symptoms like:

  • Fatigue
  • Brain fog
  • Slower cognition
  • Mood fluctuations

I want to be careful here: citicoline is not a treatment for Hashimoto’s and does not address the autoimmune process itself.

But there are a few reasons people with thyroid conditions often pay attention to nutrients like choline:

1. Brain fog and neurotransmitters

Thyroid imbalance can affect cognitive function. Since acetylcholine is involved in attention and memory, supporting its building blocks may help some people feel more mentally sharp.

2. Liver and hormone metabolism

The liver plays a role in hormone conversion and detox pathways. Choline is important for liver lipid metabolism, which indirectly connects to overall endocrine balance.

3. Methylation demand

Autoimmune conditions can increase metabolic stress on methylation pathways. Choline is one of the nutrients involved in those cycles.

None of this is a cure narrative—it’s more about supporting systems that are under extra load.

Final thoughts

For me, citicoline isn’t about fixing anything dramatic. It’s more subtle than that—it’s about supporting cognitive energy and filling a potential nutritional gap that’s easy to overlook on a vegan diet.

The key takeaway is this:

  • Vegan diets can be healthy and complete
  • But choline intake can still run low depending on food choices
  • Citicoline (CDP-choline) is a more brain-targeted form than basic choline salts
  • And in conditions like Hashimoto’s, cognitive support nutrients often get extra attention—though they are not treatments
