Why is My Libido So Low?

It’s a question many people ask themselves at some point in life: Why is my sex drive lower than it used to be? A dip in libido can feel frustrating and even worrying, but the truth is, it’s a very common experience — and one with many possible explanations.

What Causes Low Libido?

Several factors can influence your sexual desire. These can include:

• Stress and mental health – Anxiety, depression and chronic stress are some of the biggest libido-killers.
  

• Hormonal changes – Shifts in testosterone, oestrogen or cortisol can impact desire and performance.
  

• Poor lifestyle habits – Lack of sleep, excess alcohol and poor diet all play a role.
  

• Underlying health issues – Diabetes, cardiovascular problems and other chronic conditions can affect sexual function.
  

While these factors are widely known, there’s another piece of the puzzle that often goes overlooked: cellular health, specifically your NAD⁺ levels.

The Link Between NAD⁺ and Libido

NAD⁺ (nicotinamide adenine dinucleotide) is a molecule found in every cell of your body. It plays a central role in energy production, DNA repair and overall cellular function. Research suggests that NAD⁺ may also influence sexual health in several ways:

• Energy and performance: Healthy NAD⁺ levels help fuel ATP production — the energy your body needs for physical activity, stamina and performance.
  

• Hormonal balance: NAD⁺ is involved in pathways that support testosterone and other hormones linked to libido.
  

• Blood flow and circulation: NAD⁺ supports endothelial function, which plays a role in healthy blood flow — an essential factor for arousal and performance.
  

• Stress resilience: By helping regulate the body’s stress response and inflammation, NAD⁺ may reduce some of the barriers that dampen desire.
  

When NAD⁺ levels decline with age — or due to stress, poor diet, or lack of sleep — the result can be fatigue, hormonal imbalance, and a reduced sex drive.

Can Boosting NAD⁺ Improve Libido?

Supporting your NAD⁺ levels may help address some of the underlying issues linked to low libido. For example:

• If fatigue is impacting your sex drive, better NAD⁺ support could mean more natural energy.
  

• If stress and poor recovery are the problem, NAD⁺ may help your body bounce back more effectively.
  

• If circulation or hormonal changes are affecting your sexual health, NAD⁺ may play a supportive role.
  

Optimising your levels could be one part of a wider strategy for improving libido alongside lifestyle changes, good nutrition and stress management.

Supporting NAD⁺ Levels

There are natural ways to keep your NAD⁺ stores healthy:

• Exercise regularly, particularly HIIT or strength training.
  

• Prioritise restorative sleep.
  

• Eat foods rich in NAD⁺ precursors (like B vitamins, tryptophan, and polyphenols).
  

• Limit alcohol, which depletes NAD⁺.
  

For more targeted support, supplementation may help restore NAD⁺ more effectively. At NADclinic, our NADSQx Smart Pen offers an innovative way to top up NAD⁺ through precision microdosing. Portable, discreet and easy to use, it’s designed to fit seamlessly into your lifestyle and help you stay consistent with your supplementation whether at home or on the go.

The Takeaway

Low libido is rarely about one single factor. Stress, lifestyle, hormones and cellular health all play a part. If you’ve been noticing your sexual desires dip recently, it may be worth looking beyond surface-level fixes and supporting your body at the cellular level.

By restoring balance with healthy habits, and considering NAD⁺ supplementation for extra support, you can take meaningful steps toward feeling more energised, resilient and ready to reconnect with your sexual health.
