Launched in October 2025, Solgar Cellular Energy capsules are formulated to support cellular vitality, energy and healthy ageing by focusing on NAD+ production.

What is NAD+?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme used in every living cell. It is key to converting food into cellular energy, aiding DNA repair, sustaining gene expression, and enabling enzymes called sirtuins that regulate metabolism and longevity.

As people age, their NAD+ levels naturally decline. That decline is thought to contribute to fatigue, slower recovery and reduced cellular performance.

How Solgar Cellular Energy Works

Solgar Cellular Energy delivers Niagen® Nicotinamide Riboside (NR), a patented and well-researched form of vitamin B3. Inside your body, NR is converted into NAD+ within cells, which may help to generate energy more efficiently, support repair functions, and boost resilience.

To complement NR, the formula includes B vitamins and vitamin C. These nutrients support energy metabolism, help reduce fatigue, protect cells against oxidative stress and assist a healthy nervous system. Together, the ingredients aim to help your energy feel steadier and more sustainable.

What are the main benefits of Solgar Cellular Energy?

• Boosts natural energy levels: Solgar Cellular Energy supports your body’s ability to turn food into energy by increasing NAD+, a key molecule that fuels every cell. Research shows that Nicotinamide Riboside (NR) safely raises NAD+ levels in healthy adults, helping reduce tiredness and improve vitality.
• Supports healthy cell repair: NAD+ activates enzymes involved in DNA repair and cellular maintenance. By maintaining these processes, Solgar Cellular Energy helps protect your cells from everyday stress and supports normal tissue repair.
• Enhances mental and physical performance: Healthy NAD+ levels improve the efficiency of mitochondria, the energy-producing structures inside cells. This supports steady physical energy, mental focus and endurance throughout the day.
• Promotes healthy ageing: NAD+ levels naturally decline with age, affecting how cells renew and function. Supporting NAD+ production helps maintain normal cellular resilience, vitality and overall wellbeing.

Who would benefit from Cellular energy the most:

Solgar Cellular Energy is ideal for anyone experiencing low energy, poor focus or general fatigue and looking for a long-term, stimulant-free solution. It is particularly suited to adults who want to support healthy ageing, maintain cellular vitality, or enhance recovery and mental clarity.

Those with demanding lifestyles, high stress, or age-related dips in energy may notice the most benefit, especially when combined with balanced nutrition, exercise and good sleep. While not a replacement for medical treatment, it offers meaningful support for anyone aiming to optimise their energy and wellbeing at a cellular level.

Other research findings:

• Several human trials confirm that oral NR supplementation increases NAD+, often without serious side effects.
• Preclinical studies show NR activates sirtuins (e.g. SIRT1, SIRT3) and improves mitochondrial and oxidative metabolism in animals.
• Reviews see NR and other NAD+ precursors (like NMN) as promising in age-related diseases, though they emphasise the need for more rigorous clinical trials in humans. 
• Safety trials reinforce that high-dose NR is well tolerated.

Our honest opinion: is Solgar’s cellular energy worth it?

Yes, Solgar Cellular Energy is worth it. As Girish Desai, Pharmacist at Landys Chemist, explains, it is a high-quality, evidence-based choice for anyone seeking genuine cellular support rather than a quick energy fix. Solgar’s patented Niagen® Nicotinamide Riboside is a clinically validated form of vitamin B3 that converts efficiently into NAD+. This advanced form is more bioavailable and dependable than standard NAD+ supplements, allowing your body to use it more effectively for sustained energy, sharper focus and healthy ageing.

If you are looking for a supplement that supports your body’s natural energy production, cellular repair and vitality, Solgar Cellular Energy stands out as one of the best NAD+ supplements you can choose.
