Questions & Answers

4 Customer Questions

Is there supposed to be a small hole in the top of the cap?! There seems to be a corresponding "pilot hole" in the seal as well.
Answer by ChewyJul 20, 2021
There is supposed to be a small hole in the lid of Mushroom Immune Gold. The reason this exists is because otherwise the bottle would burst while traveling by airplane. This product is manufactured in the US, and then regularly distributed to countries around the globe, so the hole is necessary to prevent damage.

Can this be used if my pet is taking prednisone?
Answer by ChewyFeb 07, 2021
If your pet has a medical condition and is taking other medication, we recommend consulting with your veterinarian to ensure that this supplement is safe to use.

Can this be combined with Pet Wellbeing Kidney Support Gold?
Answer by ChewySep 14, 2019
Dietary and other healthcare changes should be made under the guidance of your vet, particularly when underlying health conditions exist.

How long is this good for once it has been opened?
Answer by ChewyDec 10, 2022
Pet Wellbeing products maintain full potency for roughly 3-5 years on average. If you turn over the bottle/s you have, you will see an expiration date printed on the bottom of the bottle. The supplement does not spoil or 'go bad' after that date passes, though it may become less potent.

I believe in this mushroom extract

After three surgeries to remove the MCT’s in which they kept coming back. I decided not to put her thru anymore surgeries, although I was told she needed chemotherapy afterwards, but I opted to try this immune gold Mushroom extract. It has helped shrink my bellboo’s tumors. She had two burst MCT’s and now they have completely disappeared. I’m a believer!!

Amended product?

Just went to give this to my dog for the 1st time and there appears to be a hole in the top of the cap. There is a corresponding imprint in the inside "foam" part, but the product itself was sealed. Very weird. I don't know how this stuff is supposed to smell, so I am very leary and not going to give to my dog. Very bizarre! Expensive chance to have taken on soemthing new. Will try ordering product direct, as they seem to be reputable!

On Third Bottle

We have an 11 year old Texas Heeler named Hank who has EPI (limited pancreas) his whole life. We add pig pancreas to his food to help him digest it and get nutrients from it. Dogs with EPI are prone to very painful bacterial infections in their gut. He started getting masses (I can't call them tumors) on his chest and one of his hip and neck in 2019. My heart sank when I saw them get bigger. EPI dogs can have other health issues brought on by the condition. We took him to the vet in Jan 2020. She said they are fatty masses, keep an eye on them to make sure they don't grow. I have already used Pet Wellbeing Thyroid Support tincture that has benefited our cat Timmy Duncan tremendously for over a decade so my next call was to Pet Wellbeing support to see what formula they recommended. They take care to find out what meds and supplements your pet is on and cross reference any side effects. They recommended these magic mushrooms. At first I thought they were pricey but Each bottle last nearly 6 months. My pet's health is priceless. Hank's two small masses have gone away and two of the golf ball sized ones have shrank to a quarter size and stopped and no new masses. We are overjoyed! We got a great review at the vet recently! We recommend Pet Wellbeing every chance we get.

I have to have hope!

My vet said nothing can be done. I have to keep trying until he is in pain I cannot control. He still has a good quality of life. And it will be a while before Gold kicks in but I will know I'm doing everything I can!
