How to Choose a Mushroom Supplement That Actually Works
4 Things to Watch Out For Before You Buy


1. Fruiting Body vs. Mycelium on Grain
Not all parts of the mushroom are equally potent.
✅ Look for “fruiting body” — this is the actual mushroom and contains the highest concentration of active compounds.
❌ Avoid “mycelium on grain” — this is often ground-up mushroom root grown in oats or rice, and it's usually filled with starch, not active ingredients. Also avoid companies that do not mention which part of the mushroom is used.
Why it matters: Products made mostly from mycelium can be cheap fillers with little to no real effect. Mycelium can be used (especially for cordyceps), but it needs to be a pure mycelium strain, not myceliated grain. Myceliated grain is what mushrooms growers use as seed, it is incredibly cheap and mostly grain.


2. Beneficial Compounds — Go Beyond “Polysaccharides”
The most important compounds in functional mushrooms are Beta 1,3/1,6 D-glucans, triterpenes, and other specific bioactives—not vague, inflated claims like “50% polysaccharides.”
✅ A quality supplement will list Beta 1,3/1,6 D-glucan content (e.g., 20–30%) based on verified lab testing.
❌ “Polysaccharides” is a broad term that can include all kinds of sugar-like compounds—including inactive starch from grain-based fillers.
Why it matters:
Without a clearly stated Beta 1,3/1,6 D-glucan percentage, there's no guarantee the product will deliver real benefits. While polysaccharide content is commonly tested and not inherently bad, brands that only disclose polysaccharides and hide glucan levels often rely on cheap fillers.
Another green flag? When a product is also tested for other beneficial compounds like:
✅ Triterpenes in Reishi
✅Erinacines or hericenones in Lion’s Mane
That said, some of these tests can be prohibitively expensive, especially for small-batch producers, so it’s not necessarily a red flag if certain compounds aren’t listed—especially if the brand is focused on keeping the product affordable and transparent.
3. Extraction Method
Mushrooms need to be extracted to release their active compounds.
✅ Look for hot water or dual extraction (hot water + alcohol). This ensures both water-soluble (like beta-glucans) and fat-soluble (like triterpenes in Reishi) compounds are present.
❌ “Raw” powders with no extraction—they're harder to absorb and much less effective. They can be high quality, but have much less effect.
Why it matters: Unextracted mushrooms pass through the body with less benefit. Polysaccharides – A type of complex carbohydrate found in Lion’s Mane, including beta-glucans, which are widely studied for their role in supporting normal immune function and gut health.


4. Blends? Only If They're Transparent
You deserve to know exactly what’s in your supplement.
✅ Look for products made with 100% pure mushroom extract, with no unnecessary additives or hidden ingredients.
❌ Be cautious of terms like “proprietary blend,” “natural flavor,” “maltodextrin,” or other vague fillers—these often signal diluted formulas.
Why it matters:
Some brands bulk up capsules or powders with cheap ingredients, offering only trace amounts of actual mushroom extract. While blends that include herbs, vitamins, or adaptogens can be beneficial, transparency is key. If a product lists multiple ingredients but doesn’t specify how much mushroom extract is included, chances are it’s not much.
While functional blends can be helpful, always make sure you’re getting a meaningful dose of real mushroom extract—not just marketing fluff.

Lion's Mane – "Brain-Boosting Mushroom"


Lion's mane (Hericium erinaceus) has been used in traditional Chinese medicine for centuries, valued for its potential to support cognitive function and overall well-being. Historical records suggest it was consumed by monks and scholars seeking to enhance focus and mental clarity. Traditionally, it was prepared as a tea or decoction and incorporated into herbal practices aimed at promoting vitality and longevity.
Buddhist Monks & Mental Clarity – Ancient Buddhist monks incorporated Lion’s Mane into their diet, believing it helped sharpen the mind, enhance meditation, and cultivate spiritual awareness. They viewed it as a tool for deepening their connection between mind and spirit.
Modern scientific research has identified several bioactive compounds in lion's mane mushroom, which contribute to its long-standing use in herbal traditions:


Polysaccharides – A type of complex carbohydrate found in Lion’s Mane, including beta-glucans, which are widely studied for their role in supporting normal immune function and gut health.
Hericenones & Erinacines – Unique bioactive compounds found in Lion’s Mane that have been researched for their potential to support nerve growth factor (NGF) production, which plays a key role in brain function, memory, and cognitive health.
Antioxidants – Like many functional mushrooms, Lion’s Mane contains naturally occurring antioxidants that help protect cells from oxidative stress, supporting overall brain and nervous system health.

Such great benefits for my health! I fought off a few colds and did not get sick, my energy levels are better and I do not have end of winter tiredness that I used to have all my life. I also love the taste – no alcohol, no artificial sweeteners. It tastes very potent. Highly recommended.

Lion's mane has helped my brain fog after long COVID. I am less forgetful and more able to concentrate. I feel like I've regained myself! This extract tastes great and is also easy on the stomach – I tried pills before and my digestive system could not tolerate it. Will buy again, thank you.
