Can NAD+ be harmful?

Nicotinamide adenine dinucleotide (NAD+) is a coenzyme found in every cell of the human body. It plays a crucial role in energy production and cellular repair, which is why it has become a popular supplement for those looking to support overall health and ageing. However, as with any supplement, it is essential to understand both the benefits and the risks before starting use. This article explores what NAD+ is, whether it can be harmful, its possible side effects and who should be cautious about taking it.

Key Takeaways

Here are the five biggest takeaways from this article about NAD+ and whether it can be harmful:

• NAD+ is a vital coenzyme involved in energy production and cellular health.

• While generally considered safe, NAD+ can cause mild side effects in some people.

• Long-term effects of NAD+ supplementation are not fully understood and require further research.

• Side effects can range from fatigue and headaches to more complex concerns in specific cases.

• Certain individuals should consult a healthcare professional before using NAD+.

What is NAD+ and why is it important?

NAD+ is a coenzyme found in all living cells. It is critical for converting nutrients into energy and supports many biological processes, including DNA repair and maintaining healthy cell function. As we age, NAD+ levels naturally decline, which can affect cellular energy and repair mechanisms. For this reason, supplements and therapies aiming to boost NAD+ have grown in popularity, particularly among those seeking anti-ageing benefits or improved cognitive and physical performance. One of the best and most popular NAD+ supplements is the Vivere NAD+ injection pen. This is a self-injectable supplement that delivers high-quality NAD+ subcutaneously.

Can NAD+ be harmful?

Studies have shown that NAD+ supplementation is generally well tolerated, but some side effects have been reported. Common side effects include muscle pain, nervous system disorders, fatigue, sleep disturbances and headaches [1]. These side effects were not considered serious or life-threatening, but they do indicate that NAD+ may not be suitable for everyone. The overall safety profile is promising, but it is essential to approach supplementation with caution, particularly if you have underlying health conditions or are taking other medications.

Is NAD dangerous in the long term?

There is limited research on the long-term use of NAD+ supplements. Early evidence suggests that while NAD+ has significant potential benefits, the impact of prolonged use remains unclear [2]. 

Some concerns include changes to cellular processes and the possible promotion of unwanted cell growth, though more research is needed to understand these risks fully.

As with many supplements, it is important to balance potential benefits with the unknowns of long-term use. For those considering ongoing NAD+ supplementation, regular consultations with a healthcare provider are recommended.

Possible side effects of NAD+ supplementation

While NAD+ can be beneficial, it is important to understand the potential risks. Reported side effects include [3]:

• Nausea

• Fatigue

• Headaches

• Mild discomfort during intravenous administration

Some studies have also highlighted possible metabolic changes and concerns that NAD+ could enhance certain cellular processes linked to tumour growth in theory [4]. These findings do not mean that NAD+ causes cancer, but they emphasise the need for further research, especially in people with a history of cancer or other metabolic conditions.

Who should be careful with NAD+?

NAD+ supplements are not suitable for everyone. People who are pregnant, breastfeeding, have certain medical conditions, or take specific medications should get advice from a healthcare professional before starting NAD+ [5]. 

People with a history of cancer, autoimmune disorders or chronic illnesses should also be cautious. A consultation with a qualified healthcare provider can help determine whether NAD+ supplementation is appropriate based on your health profile.

Final Thoughts

NAD+ plays an essential role in maintaining energy and cellular health, and supplementation can offer benefits for certain individuals. However, while generally well tolerated, NAD+ can cause mild side effects, and its long-term effects remain uncertain. Individuals considering NAD+ supplementation should seek medical guidance, especially if they belong to a group that requires extra caution.
