# 5 Signs Your Body Might Need More NR

Published April 3, 2026 • Longevity Futures Research Team

## Is Your Body Telling You Something?

Your body is constantly sending you signals. The problem is, most of us have learned to ignore them — or chalk them up to "just getting older." But sometimes, these signals point to something specific and fixable.

Here are 5 signs that NR might be exactly what your body is asking for:

### 1. You're noticing more brain fog during the day

This is one of the subtle signs that your body could benefit from NR supplementation. NR plays a key role in NAD+ production, and when levels are suboptimal, this is often one of the first things people notice.

It's not just about age — stress, diet, and lifestyle all affect how much NR your body can utilise effectively.

### 2. You're struggling to maintain your weight despite eating well

This is one of the subtle signs that your body could benefit from NR supplementation. NR plays a key role in Cellular repair, and when levels are suboptimal, this is often one of the first things people notice.

It's not just about age — stress, diet, and lifestyle all affect how much NR your body can utilise effectively.

### 3. You get sick more often than you'd like

This is one of the subtle signs that your body could benefit from NR supplementation. NR plays a key role in Brain health, and when levels are suboptimal, this is often one of the first things people notice.

### 4. Your skin has lost some of its glow

This is one of the subtle signs that your body could benefit from NR supplementation. NR plays a key role in Heart health, and when levels are suboptimal, this is often one of the first things people notice.

It's not just about age — stress, diet, and lifestyle all affect how much NR your body can utilise effectively.

### 5. Your recovery from exercise takes longer than it used to
