THORNE NiaCel 400 - NAD Supplement - Nicotinamide Riboside - 60 Capsules

Top Ingredients: Nicotinamide Riboside

Nicotinamide riboside (NR) is a form of vitamin B3 that acts as a precursor to NAD+. Unlike niacin or niacinamide, NR does not cause flushing and is converted more efficiently to NAD+ in the body. It occurs naturally in small amounts in milk and other foods, but supplementation provides a concentrated dose to boost NAD+ levels effectively.

THORNE uses high-purity NR in their NiaCel 400 formula, manufactured to meet stringent quality standards. The capsules are vegan-friendly and free from gluten, dairy, soya, and other common allergens.

What Is NiaCel 400?

NiaCel 400 from THORNE is a targeted NAD supplement containing nicotinamide riboside, a precursor to NAD+ (nicotinamide adenine dinucleotide). NAD+ is a vital coenzyme found in every cell, playing a centre role in cellular energy production, DNA repair, and maintaining a healthy circadian rhythm. As we age, NAD+ levels naturally decline, which may impact energy, recovery, and overall vitality. NiaCel 400 provides 400 mg of nicotinamide riboside per serving to help replenish NAD+ levels and support normal cellular function.*

This supplement is NSF Certified for Sport, meaning it has been rigorously tested for purity, label accuracy, and the absence of over 280 substances banned by major athletic organisations. It is also vegan and gluten-free, making it suitable for a wide range of dietary preferences.

How to Choose a NAD Supplement

When selecting a NAD booster, consider the form of the precursor. Nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) are the most researched. NR is well-absorbed and converts to NAD+ via a multi-step pathway. Look for third-party testing and certification, like NSF Certified for Sport, to ensure quality and purity. Dosage is also key – research typically uses 250-500 mg of NR daily. NiaCel 400 provides 400 mg, a clinically studied amount.

Avoid products with fillers, artificial additives, or proprietary blends that hide ingredient amounts. THORNE’s transparency and commitment to quality make their formula a trusted choice.

Who Should Consider NAD Supplementation?

NAD+ support is particularly relevant for individuals over 40, as endogenous NAD+ production declines with age. Athletes and active individuals may also benefit from improved cellular energy and recovery. Additionally, those with demanding lifestyles or irregular sleep patterns may find NiaCel 400 helps maintain energy balance and circadian rhythm.*

As with any supplement, consult a health care professional before uses, especially if you are pregnant, nursing, or taking medication.

Key Benefits of NAD+ Support

NAD+ is essential for converting nutrients into cellular energy (ATP) and activating enzymes called sirtuins, which are involved in cellular repair and longevity. By maintaining optimal NAD+ levels, NiaCel 400 may:

• Support normal cellular function as part of a healthy lifestyle.*
• Enhance energy metabolism and reduce fatigue.*
• Promote a normal sleep-wake cycle.*
• Support muscle recovery and exercise performance.*

These benefits are backed by research on nicotinamide riboside, one of the most bio-available NAD+ precursors. Unlike other forms, NR is efficiently converted to NAD+ in the body, making it a preferred choice for supplementation.

Frequently Asked Questions

What is NAD+ and why is it important?

NAD+ is a coenzyme centre to metabolism and cellular repair. It declines with age, which may contribute to age-related changes. Supporting NAD+ levels can promote normal cellular function.*

How long does it take to see results?

Individual responses vary. Some users notice improved energy and sleep within a few weeks, whilst others may need longer consistent uses.

Is NiaCel 400 safe for athletes?

Yes. NiaCel 400 is NSF Certified for Sport, meaning it has been tested for prohibited substances and is safe for competitive athletes.

Can I take NiaCel 400 with other supplements?

Generally yes, but it’s best to consult a health care provider, especially if you take other NAD boosters or B3 supplements.
