-
No Fillers or Additives: Purest Mushrooms explicitly contains “no added starch, grains, additives, preservatives, radiation or fillers”. This means you get only lion’s mane extract, without common bulking agents.
-
Organic & Traceable: All mushrooms are USDA-certified organic and grown on hardwood logs (their preferred substrate). This avoids contamination from grain substrates, and the farm-to-capsule process is fully traceable.
-
Third-Party Verification: Purest Mushrooms tests each batch in independent labs to verify beta-glucan content and purity, ensuring the reliability of any marketing claims the company makes about the quality of its compounds. The label only discloses quality-proven ingredients. (They also offer a 100% money-back guarantee for satisfaction.)
Taken together, these measures give Purest Mushrooms a best-in-class formulation. By using only fruiting bodies and a thorough extraction, Purest’s tablets maximize the neuroactive and immune-boosting compounds in lion’s mane. For example, the website emphasizes “100% Organic Lion’s Mane fruiting body extract” and no grains or fillers, an uncommon standard in the supplement industry.
Lion’s Mane Benefits: Cognitive, Neurological, and Immune Support
The potential health benefits of lion’s mane mushrooms are extensive, with a growing body of research suggesting that consuming lion’s mane mushrooms can enhance memory, cognitive performance, and overall mood. The bioactive compounds found in lion’s mane, such as hericenones and erinacines, play a crucial role in stimulating the production of nerve growth factor (NGF). This stimulation can lead to improved brain function and neuroprotection, safeguarding neurons from damage and promoting nerve regeneration. Additionally, lion’s mane exhibits significant anti-inflammatory properties, which can help reduce inflammation and support overall well-being. Lion’s mane supplements have also been associated with antidepressant-like effects and neuroprotective properties, making them a valuable resource for those looking to support their brain health and enhance cognitive performance.
Research and Studies
Clinical research on lion's mane mushroom is ongoing, with promising findings suggesting that lion’s mane supplements may offer significant cognitive benefits. For instance, a double-blind, placebo-controlled study demonstrated that lion’s mane extract improved cognitive function in individuals with mild cognitive impairment. Another study found that lion’s mane supplementation reduced symptoms of anxiety and depression in menopausal women. While further research is needed to fully understand the extent of lion’s mane’s benefits, the existing evidence indicates that it may be a valuable addition to a healthy diet and lifestyle, supporting cognitive performance and mental well-being.
Lion’s mane (Hericium erinaceus) has been studied for a variety of health effects. Its unique compounds (hericenones in the fruiting body and erinacines in the mycelium) have powerful neurotrophic and anti-inflammatory actions. Research highlights include:
-
Nerve Growth Factor (NGF) Stimulation: Lion’s mane contains both hericenones and erinacines that “promote nerve growth factor synthesis and secretion”. NGF is critical for the growth and maintenance of neurons. By boosting NGF, lion’s mane may support nerve regeneration and brain plasticity. In animal studies, these compounds crossed the blood–brain barrier and stimulated NGF production. One recent review notes lion’s mane “is capable of stimulating NGF release, regulating inflammatory processes, reducing oxidative stress, and safeguarding nerve cells”.
-
BDNF and Brain Health: In overweight humans, lion’s mane extract raised brain-derived neurotrophic factor (BDNF) levels, coinciding with improvements in memory and mood. BDNF is another neurotrophic factor linked to learning, memory and antidepressant effects. By enhancing BDNF and NGF, lion’s mane supports overall brain function and resilience.
-
Cognitive Performance: Clinical trials have begun to confirm mental benefits. In one double-blind pilot study of healthy adults, a single 1.8 g dose of lion’s mane led to significantly faster processing speed on a cognitive task (Stroop test) compared to placebo. After 4 weeks of daily use, participants also showed a trend toward lower subjective stress. These findings suggest lion’s mane can acutely sharpen attention and may reduce stress when taken consistently.
-
Mild Cognitive Impairment and Alzheimer’s: Longer trials in older adults are promising. A 16-week study in elderly individuals with mild cognitive impairment (MCI) found that 3 g/day of lion’s mane improved cognitive scores on memory tests (Mini-Mental State Exam). Another trial gave Alzheimer’s patients erinacine-enriched lion’s mane mycelium for 49 weeks and found significant gains: the treatment group improved in MMSE and daily living scales relative to placebo. In short, lion’s mane supplementation was associated with better cognition and less decline in Alzheimer’s-related measures. While more research is needed, these human studies echo decades of animal data showing lion’s mane’s neuroprotective effects.
-
Neuroprotection and Nerve Health: Laboratory studies consistently show lion’s mane has neuroprotective effects. For example, erinacines from lion’s mane promote neurite growth in neuron cells and reduce neuroinflammation in microglial models. One review notes that lion’s mane compounds display “neuroprotective and neurotrophic effects” in animal models of nerve injury, stroke and Alzheimer’s disease. In practical terms, this means lion’s mane extracts may help protect nerves from damage and support recovery after injury or stress.
Beyond the brain, lion’s mane also modulates the immune system. The beta-glucan polysaccharides in lion’s mane are well-known immune boosters. High-molecular-weight polysaccharides from H. erinaceus “strengthen the body’s immune system”. They act as biological response modifiers to increase immune cell activity. Animal studies cited in reviews show lion’s mane supplementation enhanced gut-associated immune activity and overall defense against pathogens. Additionally, erinacines and hericenones exhibit anti-inflammatory and antioxidant effects, helping regulate immune signaling and reduce damaging inflammation. Additionally, lion’s mane exhibits significant anti-inflammatory properties, which can help reduce inflammation and support overall well-being. Consistent use of lion’s mane supplements may lead to long-term cognitive benefits, including improved mental clarity, memory, and decision-making abilities. Furthermore, lion’s mane mushrooms contain bioactive substances known for improving heart health, adding to their extensive list of health benefits.
In summary, scientific evidence supports many of the traditional claims about lion’s mane. It appears to improve focus, memory and mood (through NGF and BDNF pathways), protect against age-related brain decline, and balance the immune system. Lion’s mane supplements have also been shown to reduce perceived stress, making them a valuable addition to a stress-relief regimen. Purest Mushrooms leverages these benefits by delivering concentrated lion’s mane extract in each tablet.
Types of Products
Lion’s mane mushroom supplements are available in various forms, including capsules, powder, and functional mushroom blends. When choosing a product, it is essential to consider the type of lion’s mane extract used and the concentration of bioactive compounds. Some supplements may include additional ingredients, such as other mushrooms like shiitake, to provide a wider range of health benefits. Fresh lion’s mane mushrooms can also be found in some health food stores or grown at home using a mushroom growing kit. For those who prefer a versatile option, lion’s mane mushroom powder can be easily added to coffee, smoothies, or other recipes, offering a convenient way to boost cognitive support and immune system function. Additionally, lion's mane mushroom supplements can come in various forms such as powders, capsules, and gummies, catering to different preferences and lifestyles.
What to Look for in a Mushroom Supplement
When selecting a mushroom supplement, it’s essential to consider several factors to ensure you’re getting a high-quality product. First and foremost, look for supplements made from certified organic mushrooms, such as lion’s mane mushrooms, which are known for their extensive health benefits. Certified organic mushrooms are grown without harmful pesticides and in optimal conditions, ensuring their purity and potency.

Buyer’s Guide: How to Choose a Lion’s Mane Supplement
When evaluating lion’s mane supplements, keep these factors in mind:
-
Mushroom Form (Fruiting Body vs Mycelium): Always check the ingredient source. Fruiting body extracts contain the richest supply of hericenones and polysaccharides, while supplements with mycelium (often grown on grain) may have lower potency or unwanted fillers. The best products use only fruiting bodies.
-
Extraction Method: Dual (hot water + alcohol) or triple extraction yields a full-spectrum extract. Patented or multi-step extraction (like Purest Mushrooms’ dual-extract) ensures both water-soluble and alcohol-soluble compounds are included.
-
Beta-Glucan Content: Look for a stated beta-glucan percentage on the label. Reputable brands guarantee at least 20–30% or more. If a product does not list beta-glucan content, it likely has hidden fillers diluting the potency.
-
Third-Party Testing: Choose brands that publish lab reports or seals from independent testing. Testing for purity (absence of heavy metals, pesticides) and potency (beta-glucan verification) adds trust. Purest Mushrooms tests each batch to confirm its >35% beta-glucan + active compounds guarantee.
-
Ingredients and Fillers: Read the full ingredients. The ideal supplement has only mushroom extract and that's it. Steer clear of added starches, grains, or colorings. As a rule, avoid any product that hides “myceliated grain” under different terms. Product labels for mushroom supplements can be misleading, as many popular brands use fillers like myceliated grain, which can reduce the supplement’s effectiveness.
-
Organic Certification: Organic mushrooms mean less pesticide residue and better growing conditions. The top brands (Purest Mushrooms, Real Mushrooms, FreshCap) use USDA-certified organic lion’s mane.
-
Form Factor and Dosage: Tablets or capsules can vary in size and concentration. Check that each serving (often 1–2 pills) delivers an effective dose (commonly 500–1000 mg extract). Purest Mushrooms’ tablets contain a 30-day supply at 1000 mg/day with high beta-glucans.
In summary, the best lion’s mane brand will be transparent about its source, extraction, and active content. A little research goes a long way in identifying a high-quality supplement.
