Why is Boosie’s reishi the best?

Get ready for some mind-blowing reishi facts, my friend! Our reishi is no ordinary mushroom—it packs a punch with a whopping 21% beta-glucans. That's way more than your average reishi extract you'll find out there. We're talking next-level goodness!

Now, let's debunk some marketing mumbo-jumbo. Some brands like to brag about their fancy extraction ratios, but here's the scoop: it doesn't automatically mean top-notch quality. It's just a fancy way of saying how much mushroom material they used compared to the final product. But guess what? Our whole reishi, made from those awesome fruiting bodies, beats many of those extracts claiming to have the highest ratios. We're talking beta-glucan power like you've never seen before!

So, when it comes to reishi, trust the real deal. Our reishi is here to blow your mind with its incredible beta-glucan content. Say goodbye to the average and get ready for a reishi experience that's off the charts!

What are triterpenes?

Alright, let's sprinkle some magic into this! reishi's got these awesome things called triterpenes, and they're like tiny superheroes in the mushroom world! Now, when it comes to our furry pals, these triterpenes can do wonders.

Picture this: they're like natural champions with their anti-inflammatory and antioxidant superpowers! They team up to support your pet's health, making sure their immune system stays in tip-top shape and their liver is happy and healthy.

But wait, there's more! These cool triterpenes can also be your pet's secret weapon against stress and anxiety. So, let's bring on the reishi goodness with its triterpenes, and watch your furry buddy shine with vitality and joy! It's a mushroom party you don't want to miss!

Why can the polysaccharide amount be misleading?

Here's the inside scoop on what some brands may not tell you. When it comes to key nutrients, many brands either keep it under wraps or simply don't bother with testing. Sneaky, right?

Now, let's talk about polysaccharides. Some brands might flaunt the polysaccharide content, but here's the catch: polysaccharides can include things like starch, not just beta-glucans. So, even if you see a high polysaccharide amount, it doesn't necessarily mean you're getting a high dose of beta-glucans. You could be getting a whole lot of starch and little to none of those valuable beta-glucans.

We believe in full transparency, which is why we focus on testing and disclosing the key nutrients in our mushrooms. You deserve to know exactly what you're getting, without any hidden surprises. With us, you can trust that our mushroom powders are packed with the good stuff and free from any unnecessary starchy fillers. It's all about giving you the best of the best!

How are your mushrooms grown?

Our proprietary methods are the result of some serious brainpower and research, thanks to generous grants that fueled our R&D projects. We take pride in growing our mushrooms in small batches, using nothing but the finest organic and plant-based substrates.

Once our mushrooms reach their peak maturity, we carefully dry them at 60°C. Then, we pulverise them, breaking down those stubborn cell walls for maximum goodness.

To seal the deal, we pack the powdered magic into environmentally-friendly amber glass jars before sending them on their way to your doorstep.. It's a treat for you, your furry friends and the planet, all in one package!

Which part of the reishi mushroom do you use?

Our reishi heteropolysaccharides are derived from the fruiting body.

Do you use any fillers or additives?

Nope, not a chance! Our mushroom powders are 100% organic and pure, just like nature intended. No tricks, no extras, only the good stuff for your furry friend's well-being. It's all about keeping it clean and fabulous!

Do you test your mushrooms for heavy metals?

Absolutely! We check our mushrooms for lead, cadmium, mercury, and arsenic.

Are medicinal mushrooms suitable for all pets?

When it comes to medicinal mushrooms, it's important to consider your furry friend's individual needs and consult with your trusted veterinarian.

In general, many pets can benefit from medicinal mushrooms, but there are a few factors to consider:

  • Species and size: Different species of pets may have different sensitivities or responses to medicinal mushrooms. Additionally, the appropriate dosage may vary based on your pet's size.
  • Health condition: If your pet has any pre-existing medical conditions or is on medication, it's essential to consult with your veterinarian before introducing medicinal mushrooms to their routine.
  • Dosage and monitoring: It's important to follow the recommended dosage guidelines provided by your veterinarian. Regular monitoring of your pet's response and any potential changes in their health is essential to ensure their well-being.

Remember, your veterinarian is the guiding star in your pet's health journey. They have the expertise to provide tailored advice and determine if medicinal mushrooms are suitable for your pet.
