Liposomal NAD+ supplements are often described as gentle and well-tolerated, but like any supplement, they can cause side effects for some people.
Most reported effects are mild, temporary, and linked to dose or individual sensitivity. Knowing what to expect helps you decide if it fits your routine and how to use it more comfortably.
TL;DR:
Most people tolerate liposomal NAD+ without serious issues. Some notice mild effects like nausea, headaches, or fatigue, especially when starting or using higher doses. These usually ease as the body adjusts or when the dose is lowered.

What Is Liposomal NAD+?

Liposomal NAD+ is a form of NAD+ that uses a fat-based coating to help protect it during digestion and support absorption.
NAD+ is a coenzyme found in every cell. It helps cells turn food into energy and supports processes like DNA repair.
NAD+ levels tend to decline with age. Research has reported that NAD+ levels drop by roughly 50% between ages 40 and 60, which is why interest in supplementation has grown (1).
The liposomal form wraps NAD+ inside tiny lipid bubbles. These are similar to cell membranes. This delivery style is designed to protect NAD+ from breaking down too early in the digestive tract, which may change how the body responds compared to standard oral forms.
How It Works in the Body
After ingestion, liposomal particles pass through digestion and release NAD+ or related compounds into circulation. From there, cells can use these molecules in normal metabolic pathways.
Inside the body, NAD+ plays several roles:
Supports energy production inside mitochondria
Helps enzymes involved in DNA repair function properly
Participates in cell signaling linked to stress response and aging
Acts as a cofactor for proteins that regulate metabolism and circadian rhythm
Because NAD+ is involved in so many systems, changes in its availability can sometimes be felt as short-term side effects while the body adjusts.
Common Liposomal NAD+ Side Effects

Most reported side effects are mild and tend to appear early, often within the first few days or weeks of use. They are more likely at higher doses or when starting without a gradual increase.
Digestive discomfort
Some people report nausea, stomach upset, bloating, or loose stools. Clinical reports of NAD-related compounds note that gastrointestinal symptoms are among the most common early effects (2).
These reactions may happen because digestion and liver pathways are adjusting to higher nicotinamide exposure.
Taking liposomal NAD+ with food and starting at a lower dose often helps reduce these symptoms.
Headaches or lightheaded feeling
Headaches are another commonly reported effect. These are usually described as mild pressure or dull pain rather than severe migraines.
Research on NAD precursors has reported headaches at doses around 500 to 1,000 mg per day in some participants, with symptoms often resolving without intervention (3).
Staying hydrated and lowering the dose can make a difference.
Fatigue or low energy at first
Although NAD+ is linked to energy production, some people feel temporarily tired when starting. This may seem counterintuitive, but it is often explained as a short adjustment phase while cellular metabolism shifts.
This effect is usually brief and tends to fade as the body adapts.
Flushing or warmth
A feeling of warmth, mild flushing, or skin tingling can occur, though it appears less common with liposomal forms than with high-dose niacin. This reaction is related to blood vessel dilation and is usually harmless, though uncomfortable for some.
Lower doses reduce the chance of this happening.
Dizziness
Occasional dizziness has been reported, especially in people sensitive to changes in blood pressure or energy metabolism. This is more likely when taking higher doses or combining NAD+ supplements with other compounds that affect circulation.
If dizziness persists, stopping the supplement and speaking with a healthcare professional is advised.
Less Common or Higher Dose Side Effects

These effects are reported less often and tend to show up at higher doses or in people with specific sensitivities. They are not seen in most users, but they are worth knowing about.
Changes in blood sugar response
Some research on high doses of nicotinamide has reported short-term changes in insulin sensitivity. In small human trials, doses around 1,000 to 2,000 mg per day were associated with reduced insulin sensitivity over a few weeks (4).
This does not happen in everyone, but people with prediabetes may notice changes sooner.
Liver strain at very high intakes
High doses of nicotinamide have been linked to temporary liver enzyme changes in some studies (5). These effects were seen at doses much higher than those commonly used in supplements.
For most people using moderate doses, this has not been a reported issue, but it highlights why dose matters.
Sleep changes or vivid dreams
Some people report trouble falling asleep or more vivid dreams. NAD+ is involved in circadian rhythm signaling, so changes in timing or dose may affect sleep quality, especially if taken later in the day.
Blood pressure shifts
Research on NAD precursors has reported small drops in blood pressure in some participants (6). For people who already have low blood pressure or take blood pressure medication, this may feel like lightheadedness or dizziness.
Why Liposomal NAD+ Can Cause Side Effects
Liposomal NAD+ affects basic cellular processes, which explains why side effects can happen during the adjustment phase. NAD+ plays a role in energy production, metabolism, and cellular repair. When levels change, the body sometimes needs time to adapt.
As NAD+ availability increases, several systems respond at once:
Cells increase energy-related activity
Enzymes linked to repair and stress response become more active
The liver processes more nicotinamide byproducts
Blood flow and nervous system signaling may shift slightly
These changes are usually temporary. For most people, side effects ease as the body finds a new balance, especially when the dose is increased slowly.

Is Liposomal NAD+ Safe for Long-Term Use?
Current human research suggests NAD-related supplements are generally well tolerated at moderate doses, but long-term data on liposomal NAD+ specifically is still limited.
Clinical studies on NAD precursors such as nicotinamide riboside and nicotinamide mononucleotide have reported good safety profiles over weeks to months.
Reported side effects were mostly mild and similar to placebo groups. Liposomal NAD+ uses a different delivery method, so findings are not identical, but they offer helpful context.
Long term data is limited because liposomal NAD+ is relatively new. Most studies focus on short-term use, not years of continuous supplementation. This means questions around lifetime use, very high doses, and specific medical conditions are still being explored.
Dose, product quality, and duration matter. Lower doses used consistently appear to carry less risk than high doses taken long term.
Products that are third-party tested and clearly labeled reduce the chance of unwanted reactions. Periodic breaks and medical guidance may also help reduce long-term concerns.
Who Should Be Careful or Avoid Liposomal NAD+
Some people may need extra caution or professional guidance before using liposomal NAD+.
People with prediabetes or diabetes
Those with liver conditions or elevated liver enzymes
Anyone taking blood pressure medications
People with known methylation-related genetic issues
Pregnant or breastfeeding women
Children, unless advised by a healthcare professional
If any of these apply, it is best to speak with a qualified healthcare provider before starting supplementation.
How to Reduce the Risk of Side Effects
Most side effects can be reduced with simple habits and a careful approach, especially when starting.
Start with a low dose and increase slowly over one to two weeks
Take liposomal NAD+ earlier in the day to avoid sleep disruption
Take it with food if you notice stomach discomfort
Avoid stacking it with high-dose niacin or multiple NAD boosters
Stay well hydrated, especially during the first few days
Choose products that are third-party tested and clearly labeled
Listening to your body and adjusting dose or timing often makes a noticeable difference.
Final Words
Liposomal NAD+ is generally well tolerated, but mild side effects can happen, especially at higher doses or during the adjustment period.
Most effects are temporary and related to how NAD+ supports energy production, metabolism, and cellular repair. Starting slowly and using a quality product helps lower the chance of discomfort.

FAQs
What are the most common liposomal NAD+ side effects?
The most commonly reported effects include mild nausea, headaches, fatigue, dizziness, or a warm flushing sensation. These usually appear early and tend to ease as the body adjusts or when the dose is lowered.
Can liposomal NAD+ affect blood sugar or insulin levels?
Some research on high doses of nicotinamide has reported short-term changes in insulin sensitivity. This appears more relevant at higher intakes and may matter more for people with prediabetes.
Is liposomal NAD+ safer than NAD+ IV therapy?
Oral liposomal supplements avoid risks linked to IV use, such as injection site reactions. Research also suggests that IV NAD+ does not work as marketed, since NAD+ molecules are too large to be effectively taken up by cells through drips.
How long do liposomal NAD+ side effects last?
Most mild side effects last hours to a few days. In many cases, they improve within the first one to two weeks as the body adapts.
Who should not take liposomal NAD+ supplements?
People who are pregnant or breastfeeding, children, those with liver conditions, blood sugar issues, or on blood pressure medication should speak with a healthcare professional before use.
