Focus Supplements Without Caffeine: What Is Studied, What Is Hype

Plenty of people want to concentrate better without reaching for one more coffee. That wish is the gap stimulant-free focus products aim at, and it is where Memodyne is sold: a capsule labeled for focus, clarity and energy, with no caffeine in it.

We sell it. So here is a plain account of what a label like that can promise, what the research on non-stimulant brain products shows, and how regulators have treated memory claims that went too far.

It is a structure/function claim, a type of wording the law allows without FDA approval. The FDA says such claims describe how an ingredient affects normal body function, are not approved in advance, and must be truthful and not misleading (FDA, Structure/Function Claims).

The maker must tell the FDA about the claim within 30 days of selling the product, and the label must carry a disclaimer that the FDA has not evaluated it. The NIH adds that the FDA does not decide whether a supplement works before it goes on sale (NIH ODS, Dietary Supplements: What You Need to Know).

Memodyne prints that disclaimer next to an asterisk on COGNITIVE SUPPORT FORMULA. The words on the bottle are a claim the company stands behind, not a finding anyone has checked.

It is the clearest public example of a memory claim tested in court. Prevagen is made by Quincy Bioscience, a different company with no link to Memodyne. We include it because it shows what regulators expect of any brain claim.

1. 2017

   The lawsuit

   The FTC and the New York Attorney General sued over claims that Prevagen improves memory within 90 days.

2. 2017

   The study problem

   They said the company’s own placebo-controlled study found no statistically significant gain on any of nine tasks.

3. 2019

   Warning letters

   The FTC and FDA wrote to other companies claiming their products treat or cure Alzheimer’s disease.

4. 2022

   The evidence rule

   FTC guidance said health claims need competent and reliable science, usually randomized human trials.

5. 2024

   The ruling

   After seven years, including a jury trial, a federal court ordered Quincy to stop misleading memory claims.

Sources: (FTC, Prevagen complaint (business blog)) (FTC consumer alert, Prevagen's fishy brainpower claims) (FTC consumer alert, FTC & FDA issue warning letters to supplement sellers (2019)) (FTC, Health Products Compliance Guidance) (FTC, Statement on win against Prevagen makers). None of these actions names Memodyne.

Start with the habits health sources do back. The Mayo Clinic’s memory tips include physical activity, quality sleep, staying organized, mental activity and time with other people (Mayo Clinic, Memory loss: 7 tips to improve your memory). None of them comes in a bottle.

• Move before the hardest task of the day, even for a short walk.
• Write tomorrow’s top three tasks down tonight.
• Protect a regular bedtime on work nights.
• Tackle tough problems with a colleague instead of alone.
• Bring your medicine list to your next visit; some medicines affect memory.

If focus has slipped for weeks, look past supplements. The NIA lists depression or stress, medicine side effects and thyroid problems among causes of dementia-like symptoms that treatment may reverse (NIA (Alzheimers.gov), What Is Dementia?). Our memory and focus guide covers the warning signs.
