Top NAD+ Supplements for Energy in 2025

By Kim Fields

Published: June 28, 2025

Do you often feel sluggish even after a full night's sleep? The reason is not necessarily stress or poor sleep, but can be your reduced NAD+ levels.

NAD+ is a coenzyme naturally present in body cells. NAD+ improves the core functions of our body, like:

Energy metabolism
Cellular repair
Longevity
Overall wellness

But the problem is that NAD+ levels decline as we age. With this decline comes fatigue, slower metabolism, and aging signs.

This makes NAD+ supplements, specifically NAD+ precursor, popular. These nutrients boost NAD levels naturally, providing:

Energy
Sharper focus
Long-term aging benefits

In this article, we will guide you on the best NAD+ supplements available and how to make the best choice.

What Makes a Good NAD+ Supplement?

There are so many choices for cellular energy boosters and anti-aging supplements available in the market, making it difficult to choose what works. Here’s what to pay attention to:

High Purity & Quality Ingredients

Choose supplements with no fillers, binders, or synthetic additives. Trusted companies have transparent supply chains. They use pharmaceutical-grade ingredients. A pure formula is more effective.

Type of NAD+ Precursor

Not all precursors have the same effect. The most popular NAD+ precursors are:

NMN: NMN is a direct NAD+ precursor. It effectively converts to NAD+.
NR: Nicotinamide Riboside is a highly bioactive form. They are often regarded as the best NAD+ vitamins.
Niacin (Vitamin B3): It is a classic precursor. It is budget-friendly and may induce redness.

Absorption & Bioavailability

The best supplement is effectively absorbed and used by our body. The supplements that bypass digestive breakdown are preferred, such as:

Liposomal delivery systems
Sublingual tablets
Prolonged-release capsules

Independent Testing & Certifications

The supplements for which the brands provide third-party testing and certifications like GMP, NSF, or USP are better for intake. This certificate ensures that the supplement contains the claimed ingredients; no more, no less.

Top 5 Best Supplements in 2025

The top NAD+ precursors and supportive compounds that are popular in 2025 are:

Nicotinamide Riboside (NR)

A leading and widely researched NAD+ precursor, NR is the most trusted supplement today. It is converted to NAD+ through a well-mapped biological pathway, enhancing:

Cellular repair
Energy metabolism
Brain health

Top Picks: Tru Niagen®, Life Extension NAD+ Cell Regenerator

Scientific Backing: Proven human clinical data

Best for: Ideal for:

Mental clarity
Metabolic balance
Longevity

Nicotinamide Mononucleotide

NMN supplements are most trusted for a fast NAD+ boost. It easily converts to NAD+. It is a favorite choice for athletes and anti-aging enthusiasts.

Top picks: ProHealth Longevity NMN Pro, Toniiq NMN

Combines well with: Resveratrol and TMG for enhanced effect

Best for: Ideal for:

Physical appearance
Mitochondrial function
Longevity

Resveratrol

Resveratrol does not procure NAD directly. It is a powerful antioxidant that activates sirtuins, which help in DNA repair and longevity.

Bonus: A staple in advanced longevity supplements. It is found in red wine.

Often paired with: NMN or NR in longevity stacks

Best for: Ideal for:

Anti-aging
Inflammation
Cellular metabolic function

Trimethylglycine (TMG)

Methyl groups help our body to convert NMN or NR to NAD+. TMG supports this methylation process. It prevents potential imbalances or fatigue caused by prolonged supplementation.

Best for: Methylation process, mood balance, support in NAD+ stacks, cellular health

Also called: Betaine

Smart tip: For higher intake of NMN or NR, add TMG to your supplementation

Quercetin

Quercetin is a plant-based flavonoid. It is known for its senolytic properties. It helps clear out old, dysfunctional cells that make ineffective use of NAD+.

Best for: Cellular cleanup, immune support, long-term wellness

Natura; source: Onions, apples, green tea

Often found in: NAD+ + senolytic formulas

Niacin (Vitamin B3)

Niacin is a classic, budget-friendly NAD+ precursor. It is an effective supplement that causes a “flushing” sensation at high doses.

Best for: Budget-conscious users, NAD+ beginners

Pterostilbene

Its structure is similar to resveratrol. It is more bioavailable and lasts longer in the body.

Best for: Synergic effect when combined with NMN for advanced longevity support

Often paired with: NR or NMN

Apigenin

Apigenin inhibits CD38, an enzyme that breaks NAD+. It makes NAD+ stick within.

Best for: Ideal for:

NAD+ preservation
Cellular protection
Reduces NAD+ loss

L-Theanine

L-theanine is not a direct NAD+ precursor. It enhances calm, focused energy and complements well with NAD+.

Best for: Ideal for:

Stress-free productivity
Focus
Mental clarity

Fisetin

Fisetin is a senomorphic compound. It works well along with Quercetin. It supports cellular longevity by clearing out damaged or aging cells.

Best for: Anti-aging, longevity

Benefits of the Best NAD+ Supplements

The right NAD+ supplementation offers many benefits beyond just an energy lift. Users report the following benefits:

Boost in Energy & Stamina

NAD+ is vital for ATP production. It boosts both physical and mental energy throughout the day.

Improved Cognitive Function

NAD+ supplements improve cognitive abilities like:

Better focus
Memory
Clarity
Neuron health

Slower Aging Signs

NAD+ activates longevity-related pathways. It supports DNA repair, slowing visible and internal aging.

Better Metabolic Health

NAD+ improves metabolic health. Increased NAD+ levels help improve:

Fat oxidation
Insulin sensitivity
Metabolic health

How to Choose the Right NAD+ Supplement for You

No supplement is perfect. The following tips will help you personalize your pics:

Your Age

NAD+ levels will start to decline at the age of 35. You must choose the NMN or the premium NR supplement.

Your Health Goals

For Better Workouts NMN + TMG

Focus and brain support NR + Resveratrol

Anti-aging Full NAD+ stack with senolytics

Your Budget

High-end stacks offer synergy but come with a price tag.
Niacin + quercetin offers benefits at a more affordable cost.

Your Lifestyle Needs

Want simple labels? Seek supplements that are vegan, gluten-free, and non-GMO.
Need convenience? Prefer shelf-stable capsules or sublingual tablets.

Tips for Maximizing Effectiveness

Some simple strategies will maximize the effectiveness of the supplement:

Time is Everything

Prefer taking NAD+ booster in the morning when your body’s natural NAD+ cycle is highest. If taking Resveratrol, take it with a light fat source for better absorption.

Pairing with Other Supplements

Stacking NMN or NMN with TMG and resveratrol helps amplify stress reduction using methylation pathways.

Support with Lifestyle

You can support NAD+ working by the following lifestyle changes:

Exercise
Antioxidant-rich diet
Sleep well
Avoid alcohol and refined sugar

Conclusion

The technology behind NAD+ is improving. 2025 has brought us a new wave of supplements that will help maximize cellular capabilities. If you want to stay sharp in your 30s or you want longevity in your 60s, boosting NAD levels naturally can help you feel:
