Our Patients' Results

Speak for Themselves

+3

hrs

of daily energy gained

"Every day around 2 in the afternoon I would hit a wall and basically shut down. Six weeks into NAD+ injections and that crash is completely gone. My whole afternoon is productive now and I have not touched an energy drink since week three."

Sarah M., 44
A real Lttl patient

8

weeks

to think clearly again

"The brain fog was the worst part. I am a financial advisor and I could not stay sharp through a long meeting anymore. Eight weeks on NAD+ and I am tracking everything again. My clients have noticed. My wife has noticed. I feel like myself."

Mark T., 52
A real Lttl patient

4

weeks

no afternoon fatigue

"I have two kids and run a small business. The afternoon crashes were killing my productivity. After four weeks of NAD+ I stopped reaching for coffee after lunch and actually feel sharp through dinner. I did not expect it to work this fast."

Jennifer K., 38
A real Lttl patient

6

months

on NAD+ and counting

"I am a retired surgeon and I am extremely skeptical of wellness trends. I started NAD+ after reading the peer-reviewed literature on mitochondrial function. Six months later my memory recall is better than it was at 45. The science checks out."

David R., 57
A real Lttl patient

12

lbs

lost without major diet changes

"My doctor recommended NAD+ alongside my longevity plan. Within three months my metabolism felt like it woke up again. I lost twelve pounds without changing my diet significantly and my skin actually looks different. I feel ten years younger."

Maria S., 31
A real Lttl patient

2

weeks

back to morning workouts

"I have been lifting for twenty years and the last three I felt like I was running on empty. Two weeks into NAD+ and my recovery was completely different. I am sleeping deeper, waking up ready to go, and hitting numbers in the gym I have not seen since my thirties."

A real Lttl patient

90

days

to feel like myself again

"Perimenopause hit me hard. The fatigue and brain fog were constant and nothing was helping. My gynecologist suggested NAD+ as part of a hormonal support protocol. Ninety days later I finally feel like the person I was before all of this started."

Patricia L., 55
A real Lttl patient

+2

hrs

of focused work daily

"I run a finance team and I need to be sharp for twelve hour days. After three weeks on NAD+ I noticed I could sustain focus for two extra hours without hitting a wall. My assistant asked what changed. I told her nothing and she did not believe me."

We've got you!

You have questions, we have answers.

NAD+ (Nicotinamide adenine dinucleotide) is a coenzyme that plays a crucial role in various cellular processes, including energy metabolism, DNA repair, and cellular stress response. NAD+ levels decline with age, and supplementation with NAD+ has been shown to have beneficial effects on health and longevity.

NAD+ works at the cellular level by fueling the mitochondria, which produce your body's energy. It also activates sirtuins, a family of proteins linked to longevity and inflammation control, and supports DNA repair enzymes that keep your cells functioning correctly as you age.

Lttl is a telehealth medicine company that connects patients with licensed physicians to prescribe evidence-based treatments including NAD+ injections. We handle everything from your initial consultation to pharmacy-direct delivery, so you can focus on feeling better.

No. Lttl operates outside of the traditional insurance model. You pay a straightforward subscription price with no hidden fees, no monthly membership traps, and no prior authorization delays. Everything is transparent and billed directly.

Early research suggests NAD+ may support brain health by reducing neuroinflammation and supporting mitochondrial function in neurons. While it is not a cure or approved treatment for Alzheimer's, preliminary studies show promise and our physicians can help you understand whether it fits your longevity goals.

Dosing depends on your age, weight, health history, and treatment goals. After your intake, a licensed Lttl physician will review your information and recommend a starting dose. Most patients begin at 100mg and adjust over the first few weeks based on response.

Yes. Every Lttl patient is reviewed and approved by a licensed physician in their state. Your doctor sets your prescription, monitors your progress, and is available for follow-up. You are not getting a wellness app recommendation, you are getting a real medical opinion.

Yes. All medications dispensed through Lttl are compounded by 503A and 503B licensed pharmacies that operate under FDA oversight. Every batch is tested for purity, potency, and sterility before it ships to your door.
