Is NMN Suitable for Vegans? Plant-Based Supplement Guide Australia

Vegan Supplement Guide · Updated June 2026

Australia has one of the world's highest rates of veganism and plant-based eating — estimates suggest 2.5 million Australians follow a vegan or predominantly plant-based diet. When considering NMN supplementation, vegans reasonably ask: is NMN actually vegan-compatible? The question is more nuanced than a simple yes or no.

The short answer: the NMN molecule is vegan. The capsule you swallow may or may not be. Other formula ingredients need checking. And there is a vegan-specific reason why NAD+ restoration may be more relevant for plant-based eaters, not less.

Is NMN Itself Vegan?

Yes. NMN (Nicotinamide Mononucleotide) is a naturally occurring molecule found in small amounts in plant foods — edamame, broccoli, avocado, tomatoes — as well as in animal products. For commercial supplement production, NMN is manufactured through microbial fermentation — a process that uses bacterial cultures and plant-based feedstocks, producing NMN without any animal involvement.

Pharmaceutical-grade beta-NMN — like Nadovia uses — is produced through fermentation and is inherently vegan. There is no animal-derived component in the NMN molecule or in its standard manufacturing process.

The Capsule Question — The Critical Vegan Check

This is where many supplements fail the vegan test. Capsules come in two primary forms:

Nadovia's entire product range uses vegan HPMC cellulose capsules. Many budget NMN supplements — particularly imported brands — use gelatin capsules without clearly disclosing this. Always check the capsule material, not just the active ingredient, when evaluating NMN for vegan compatibility.

Are the Other Formula Ingredients Vegan?

For vegans considering the Nadovia Longevity Complex (NMN + Resveratrol + Pterostilbene + Quercetin + TMG + B12):

• trans-Resveratrol: Derived from Japanese knotweed or grape extract — plant-derived and vegan ✓
• Pterostilbene: Derived from blueberry extract or synthesised from plant phenols — vegan ✓
• Quercetin: Derived from plant sources (typically sophora japonica flower buds) — vegan ✓
• TMG (Trimethylglycine): Derived from sugar beet — fully vegan ✓
• Methylcobalamin B12: Produced by bacterial fermentation — vegan ✓

The entire Nadovia Longevity Complex formula is vegan-compatible — molecule by molecule, from active ingredients to capsule material to manufacturing process.

Do Vegans Have Lower NAD+ Levels?

This is the vegan-specific consideration most NMN brands miss. There is emerging evidence that plant-based diets may result in lower baseline NAD+ levels than omnivorous diets — for a specific reason:

Dietary NAD+ precursors are found in highest concentrations in animal products. Chicken breast, beef, fish, and dairy provide tryptophan, niacin, and other NAD+ precursors in readily bioavailable forms. While plant foods do contain precursors (edamame, mushrooms, avocado), the total dietary NAD+ precursor load is generally lower on a fully plant-based diet.

Additionally, B12 deficiency is more common in vegans who do not supplement — and B12 is directly required for the methylation cycle that NMN supplementation operates within. Suboptimal B12 can limit the effectiveness of the NMN-TMG-methylation pathway.

The implication: NAD+ restoration via NMN supplementation may be more relevant for vegans than for omnivores — not less. Combined with a methylcobalamin B12 supplement (included in Nadovia's Longevity Complex), it provides both NAD+ restoration and the B12 that vegan longevity protocols should not omit.

B12 for Vegans in a Longevity Stack

This deserves special mention for Australian vegans. B12 deficiency is one of the most common nutritional deficiencies in vegan populations — Healthdirect Australia specifically flags B12 as a nutrient requiring supplementation for most vegans.

Nadovia includes 150mcg methylcobalamin B12 per serving — the active, neurologically bioavailable form — which serves both the methylation cycle support needed for NMN supplementation AND the B12 baseline that vegans need to maintain. For plant-based Australians, Nadovia's Longevity Complex effectively handles two supplementation needs in one daily dose.
