Ever had someone's name right on the tip of your tongue — and it just won't come?

That's not aging. That's low acetylcholine.

From my research into brain chemistry, acetylcholine is the neurotransmitter that runs your memory, your learning, your focus. Every time you remember a name, learn something new, or concentrate on a task — acetylcholine is doing the heavy lifting.

And your brain makes it from one thing. Choline.

No choline, no acetylcholine. Most people aren't getting anywhere near enough. Eggs are the best food source — about 150 milligrams per egg. But you need 400 to 550 milligrams a day. Unless you're eating three or four eggs every morning, you're falling short.

And you're feeling it. The brain fog. The forgetfulness. That frustrating blank where a word used to be.

Two forms worth knowing. Alpha GPC — about 40 percent choline by weight, crosses the blood-brain barrier efficiently. Citicoline — also called CDP-choline — gives you both choline and a compound that repairs brain cell membranes. Both work. Citicoline has a slight edge for overall brain cell health.

300 to 600 milligrams of Alpha GPC. Or 250 to 500 milligrams of citicoline. Morning.

Now step back and look at what we've built.

Magnesium l-threonate — strengthening connections. Lion's Mane — growing new neurons. Choline — supplying the raw material for your brain's primary memory chemical.

Three supplements. Three different pathways. All working together.

But there's one more piece. The actual building material of your brain cells. Ask me about Omega-3 DHA.

Your brain is literally made of it.
