Sound familiar?

The plan is working. Your head is a step behind.

  1. 01You read the same paragraph three times and could not tell anyone what it said.
  2. 02The word is right there, on the tip of your tongue, and it will not come.
  3. 03You walked into the room, stopped, and could not remember why.
  4. 04By early afternoon you are running at about eighty percent, and the day is not done.

You are not losing your edge. You are running on less.

What the research shows

  • People on a GLP-1 protocol typically take in 16 to 39 percent fewer calories than before.[8]
  • People who are dieting score lower on immediate word recall and react more slowly on attention tests. Researchers first measured it decades ago.[6]
  • Even mild dehydration, one to two percent of body weight, dents short-term memory and concentration.[7]

Fewer calories, less water, shorter nights, and a lot still expected of you. The weight-loss side of this got remarkable. The support for everything else did not keep up. Focus is built for that gap.

Why memory, not just focus

Built for memory, not just focus.

Most focus products are a caffeine pill with a better label. Focus starts somewhere else.

Your brain runs attention and recall on the same neurotransmitter: acetylcholine. Finding the word. Holding the thread of a conversation. Remembering what you walked in for. When acetylcholine runs short, all three get harder.

To make it, your brain needs choline. Citicoline (CDP Choline) is the form of choline built for the job. Once absorbed it splits into choline and cytidine, and your brain uses both. Choline becomes acetylcholine. Choline and cytidine together become phosphatidylcholine, a main building block of the membranes your neurons signal through.

That is why citicoline is the one ingredient in Focus that is not about the first hour. The L-theanine and caffeine you feel the same morning. Citicoline's support for memory and learning builds with consistent daily use, which makes Focus a two-tablets-every-morning habit, not a pill you take when you remember to.

Citicoline has been studied in placebo-controlled human trials for both attention and memory in healthy adults. Focus gives you 250 mg per serving, the daily amount used in a four-week, placebo-controlled attention study, and every dose is on the label so you can look it up yourself.[1][2]

What is inside, and how much

Every dose, on the label.

Seven actives, each at a dose you can look up. This is the whole point of Retabolic. Here is exactly what is in a serving.

  • Citicoline (CDP Choline)250 mg The memory ingredient most caffeine-based focus products skip. Supports memory, learning, and recall.
  • L-Theanine200 mg Smooths the edge off caffeine for calm, steady attention. The amount used in the attention studies.
  • Caffeine (from caffeine anhydrous)160 mg About one strong cup of coffee, paired with theanine so it is not a jolt.
  • L-Glutamine150 mg An amino acid the body leans on when you are eating less.
  • L-Leucine110 mg A branched-chain amino acid, there for the days you train in a deficit.
  • L-Glutathione100 mg The body's master antioxidant. Supports your own antioxidant defenses.
  • Chromium30 mcg Supports normal macronutrient metabolism.

No proprietary blends. No fairy dusting. If it is on the label, it is in the bottle at the dose shown.

Energy without the crash.

Coffee gives you the caffeine and the drop. Focus pairs about the caffeine in one strong cup with 200 mg of L-theanine, the amino acid in green tea that smooths the edge. That pairing is why the energy feels steady instead of spiky, and why you are less likely to feel the slump a couple of hours later.

In placebo-controlled studies, L-theanine taken with caffeine raised self-rated alertness and lowered self-rated tiredness. The 200 mg of L-theanine in Focus was studied together with exactly the amount of caffeine in one serving, in a placebo-controlled attention trial. Same amounts, no guesswork.[3][4][5]

Take two tablets once a day in the morning, with food. New to it? Start with one tablet for the first week.

Focus versus the usual fixes

Steady focus, not a spike.

Four things a serving of Focus has that the usual fixes do not.

What is in it Focus Coffee Energy drinks Stim-only pills The usual
Caffeine balanced with 200 mg of L-theanine for calm, steady attention Yes No No No No
250 mg of citicoline for memory and recall Yes No No No No
100 mg of L-Glutathione, the master antioxidant Yes No No No No
Amino acid and mineral support for the days you eat less Yes No No No No

Coffee and energy drinks bring the caffeine and the drop. Focus brings the caffeine, the calm, and the memory ingredient, at doses printed on the label.

What it costs

$22.97. Thirty days. About 77 cents a day.

Less than a cup of coffee a day, with the coffee already in it.

Who it is for

Built for the days that ask the most of you.

  1. 01On a GLP-1 protocol, doing everything right, and your head is a step behind.
  2. 02Training in a deficit and still expecting a real session.
  3. 03Busy mornings where you need to be sharp on less fuel.
  4. 04Anyone who reads the label before they buy, and wants the doses to actually be there.

Stack it right

Focus is the focus piece. Keep your basics.

Eating less can leave gaps that no focus formula fills. In one study of more than 460,000 adults, more than 1 in 5 who started a GLP-1 protocol were diagnosed with a nutritional deficiency within their first year.[9] Focus is not a multivitamin, and it does not pretend to be.

Keep the basics that fit your protocol. Focus does not contain any of them, so it stacks cleanly on top of all of them. One more line on the same page of your morning.

If you take a prescription medication, check with your healthcare provider before adding Focus to your routine.

  • Protein at every mealThe first thing a smaller appetite crowds out.
  • Water with electrolytesMild dehydration shows up as fog before it shows up as thirst.
  • B12 and vitamin DThe two your provider is most likely to check.
  • Creatine, if you take itStacks alongside Focus without overlap.

Most brain supplements hide the dose. We print it.

What to expect

The first hour, the first week, and after.

Two tablets, every morning, with food.

Day 1

Two tablets with breakfast. Within about an hour, the lift: alert, calm, on task. That is the L-theanine and caffeine.

Week 1

New to it? One tablet a day for the first week, then two. Morning only. Caffeine late in the day can get in the way of sleep.

Weeks 2 to 4, and on

Citicoline's support for memory and learning builds with daily use. Keep the habit. Results vary from person to person, which is why we print the doses instead of promises.

From the founder

I have run GS Labs since 2004. I built Focus because the people I hear from, on a GLP-1 protocol or just cutting hard, keep telling me the same thing: the plan is working and my head is not. Most brain supplements answer that with a proprietary blend and a big promise. I wanted the opposite. Seven actives, every dose printed on the label, a memory ingredient most caffeine-based focus products skip, and a price that makes sense without a subscription. If it is not for you, reach out to our support team at hello@retabolics.com and we will make it right.

Questions

Straight answers.

Is Retabolic Focus a memory supplement or a focus supplement?
Both. It is a brain supplement for memory and focus. Citicoline supports memory, learning, and recall; L-theanine and caffeine support attention and steady energy. Most focus products stop at the caffeine. Focus does not.
Can I take it on a GLP-1 protocol?
Focus was designed with GLP-1 protocols in mind. It supports focus, memory, and clean mental energy during a caloric deficit. It is a dietary supplement, not a medicine, and it does not replace food, water, or your basics. If you take a prescription medication, check with your healthcare provider before adding it to your routine.
Will it help with brain fog?
Brain fog is not a diagnosis. It is the word people use for feeling slow, foggy, and a step behind. Focus is built to support mental clarity, focus, and steady energy on the days you are running on less. It is a dietary supplement, not a medicine.
How much caffeine is in it?
160 mg per two-tablet serving, about one strong cup of coffee, balanced with 200 mg of L-theanine so the energy is steady, not jittery. New to it? Start with one tablet, which is half that.
When should I take it?
Two tablets once a day in the morning, with food. New to it? Start with one tablet for the first week. Because of the caffeine, take it earlier in the day rather than later.
Can I take it with coffee?
You can, but count the caffeine. A serving of Focus is about one strong cup. If you add coffee on top, keep an eye on your total for the day, and take Focus earlier rather than later.
What does it cost, and is there a bigger pack?
$22.97 for 60 tablets, a 30-day supply, on Amazon. A two-bottle, 60-day pack is on the same Amazon page for $38.97. Prices are set on Amazon and can change; the Amazon page is always current.
Does it replace my vitamins?
No. Focus is a focus and memory formula, not a multivitamin. Keep the basics that fit your protocol: protein, water with electrolytes, and the B12 and vitamin D your provider recommends.
Any side effects?
Focus contains caffeine. If you are sensitive to caffeine, start with one tablet, take it early, and avoid stacking it with other caffeine. Do not take it late in the day; caffeine can get in the way of sleep. Not for anyone under 18. Talk to your provider first if you are pregnant, nursing, or take a prescription medication.
Is it third-party tested?
Yes. Retabolic Focus is third-party tested for purity and potency.
What makes it different?
Full label transparency. Every active is listed at its exact dose, there are no proprietary blends, the doses are clinically informed, and it costs $22.97 a bottle with no subscription.
Where do I buy it?
Right now, on Amazon, with fast Prime shipping. The full Retabolic store is coming soon.
What is your return policy?
If Focus is not right for you, email our support team at hello@retabolics.com and we will make it right.
