How to Choose the Best Lion’s Mane Supplement in New Zealand
Lion’s Mane has become one of the most popular mushroom supplements in New Zealand, especially for people looking to support focus, clarity, and cognitive wellbeing.
But with more products now available, choosing the best Lion’s Mane supplement is not always straightforward.
Some products use fruiting body. Some use mycelium. Some are extracted, some are simply powdered, and some provide clear independent testing while others offer very little detail at all.
If you’re trying to choose a high-quality Lion’s Mane supplement in New Zealand, here are the key things worth looking for.
Quick Answer: What Makes a Good Lion’s Mane Supplement?
A good Lion’s Mane supplement should clearly state the species used, be made from a quality mushroom source, use an appropriate extraction method, and provide independent testing for purity and potency.
For most people looking for cognitive support, the species to look for is Hericium erinaceus, the Lion’s Mane mushroom used in the majority of scientific research.
What to Look for at a Glance
| Factor | What to Look For | Why It Matters |
|---|---|---|
| Species | Hericium erinaceus | This is the Lion’s Mane species most commonly used in research. |
| Mushroom material | Fruiting body, or clearly explained mycelium | Helps avoid low-quality products diluted with grain. |
| Extraction | Extracted, ideally dual-extracted | Extraction helps concentrate the beneficial compounds. |
| Testing | Independent beta-glucan and contaminant testing | Confirms purity, potency, and product quality. |
| Transparency | Clear sourcing, ingredients, and lab reports | Makes it easier to know what you’re actually buying. |
1. Check the Species Name
The first thing to check is the species name.
True Lion’s Mane is Hericium erinaceus. This is the mushroom most people are referring to when they talk about Lion’s Mane supplements for focus, clarity, and cognitive support.
In New Zealand, this can get confusing because Pekepeke-Kiore, a native species also known as Hericium novae-zealandiae, is sometimes referred to as “NZ Lion’s Mane.”
While both mushrooms belong to the Hericium genus, they are different species. If you’re looking for the Lion’s Mane used in most scientific research, look for Hericium erinaceus on the label.

2. Understand Fruiting Body vs Mycelium
Lion’s Mane, like other mushrooms, has different parts. The fruiting body is the visible mushroom itself. The mycelium is the root-like network that grows through a substrate such as wood, grain, or liquid culture.
Many traditional mushroom supplements use the fruiting body because it is the part people recognise as the actual mushroom and is naturally rich in beneficial compounds such as beta-glucans.
Mycelium is not automatically bad. In some cases, mycelium can be valuable, especially when it is grown in a clean liquid culture and properly separated before extraction.
The concern is usually with mycelium grown on grain. In these products, the mycelium is often not fully separated from the grain before processing, meaning the final product can contain a significant amount of starch or grain material rather than pure mushroom extract.
That’s why it’s important to look for clear labelling. If a product uses mycelium, it should explain how it is grown, whether grain is present, and how the final extract is tested.
3. Look for an Extract, Not Just Mushroom Powder
Not all Lion’s Mane products are extracted.
Some products are simply dried mushroom powder. While this still contains mushroom compounds, much of the beneficial material remains locked within the mushroom’s tough chitin cell walls, which humans struggle to digest effectively.
Extraction helps break down these cell walls and concentrate the beneficial compounds, making them far more accessible and bioavailable.
High-quality Lion’s Mane extracts often use hot water extraction, alcohol extraction, or both. Water extraction is commonly used to draw out beta-glucans, while alcohol extraction is used to extract compounds such as hericenones.
A dual-extracted Lion’s Mane supplement uses both water and alcohol extraction to capture a broader range of compounds from the mushroom.
If a product does not clearly explain whether it is an extract or simply a powder, that is worth questioning.
4. Check for Beta-Glucan Testing
Beta-glucans are one of the key groups of compounds found in functional mushrooms. They are commonly used as a measurable marker of mushroom extract quality and potency.
This matters because some products only list “polysaccharides,” which can be misleading. Polysaccharides can include beta-glucans, but they can also include starches from grain or other filler material.
A product that only advertises a high polysaccharide percentage may not actually be high in meaningful mushroom compounds.
Independent beta-glucan testing gives a clearer picture of what is actually in the product.
Beta-glucan levels can vary significantly between products depending on the mushroom material used, the extraction method, and whether grain is present in the final extract. In independent testing, we have seen Lion’s Mane products range from the low 20% range through to over 30% beta-glucans.
Flow State’s Lion’s Mane is tested for beta-glucans every batch, with results published through our third-party testing reports.

5. Look for Independent Testing for Purity and Safety
Mushrooms are bioaccumulators, which means they can absorb substances from the environment they are grown in.
That is why independent testing matters.
A good Lion’s Mane supplement should be tested for more than just active compounds. It should also be tested for contaminants such as heavy metals, pesticides, and microbial contamination.
This is especially important if you are taking a supplement daily.
When choosing a Lion’s Mane supplement in New Zealand, look for a brand that is open about its testing process and willing to share lab reports publicly.
6. Be Careful With “NZ Grown” Marketing
Many New Zealanders naturally prefer locally grown products, and in many food categories that makes sense.
But with Lion’s Mane supplements, “local” does not automatically mean better.
True Lion’s Mane (Hericium erinaceus) cannot legally be cultivated in New Zealand, so products marketed as “NZ Lion’s Mane” are typically referring to Pekepeke-Kiore, a different native species.
That does not mean those products have no value. It simply means they should not be treated as identical to the Lion’s Mane used in most scientific research.
The more important questions are:
- What species is being used?
- Is it fruiting body, mycelium, or a combination?
- Has it been extracted?
- Has it been independently tested?
- Are the test results available?
In other words, quality depends less on the country of origin and more on the species, growing method, extraction method, and testing standards.
7. Choose a Format That Fits Your Routine
The best Lion’s Mane supplement is also one you’ll actually take consistently.
Capsules are simple, convenient, and easy to add to a daily routine. Powders can be added to drinks, smoothies, or coffee alternatives, but they require a little more preparation.
For many people, capsules are the easiest place to start because the serving size is consistent and there is no taste or mixing involved.
If you prefer a morning drink ritual, a Lion’s Mane powder or blend may be a better fit.
Liquid tinctures are another increasingly popular format in New Zealand. Some tinctures are made using properly extracted mushroom material, while others may contain relatively low amounts of actual mushroom extract.
One of the challenges with tinctures is that it can be difficult to tell how much concentrated mushroom extract you are actually getting, especially if the product does not clearly state extraction ratios, mushroom content, or beta-glucan levels.
A high-quality tincture should still clearly explain the species used, extraction method, and amount of mushroom material present, rather than simply focusing on the liquid format itself.

Final Thoughts: The Best Lion’s Mane Supplement Is the One You Can Trust
When choosing the best Lion’s Mane supplement in New Zealand, it’s easy to get caught up in bold claims, local marketing, or impressive-sounding percentages.
But the most important details are usually simple:
- Does the product clearly state the species?
- Does it explain what part of the mushroom is used?
- Is it extracted?
- Is it independently tested?
- Can you view the results?
