Why holy cap? Why holy cap?


HOLY CAP combines Eastern and Western holistic remedies to create unique blends that maximizes the benefits of functional mushrooms and superfoods for dogs and cats.

Our approach addresses health issues from multiple angles. We use functional mushrooms to enhance and maintain the immune system and essential bodily functions, while using superfoods to target specific symptoms and ailments.

According to our customers, positive effects may be noticeable within the first 2 weeks, sometimes even within a few days. However, as a pure natural food supplement, it may take 6-8 weeks to reach its full potential.

Vet Formulated

HOLY CAP was born with the help of Dr. Vicky Simon, a veterinary surgeon who practices integrated veterinary medicine by combining conventional and holistic approaches. Dr. Simon is particularly passionate about the fusion of functional mushrooms and superfoods and uses them extensively in her own holistic medicine referral practice in Somerset, South West England to help treat a wide range of conditions in cats, dogs, and other animals.

No fluff, no fillers

We strictly use whole food ingredients ONLY. We avoid additives, preservatives, flavor enhancers, and other artificial ingredients. With us, what you see is what you get! No nonsense, just the good stuff.

100% Mushroom Extract Powder

Our mushrooms undergo a dual extraction process using a patented technique called "membrane separation technology." This process removes heavy metals from our mushroom extracts, allowing us to produce 100% pure extracts and increase the bioavailability of active ingredients. It's not simply crushed mushroom powder.

Extracts from Mushroom Fruiting Body Only

Our mushroom extracts come strictly from the mushrooms’ fruiting body only, and not from the mycelium (Except for Chaga, all the good stuff is in that rock looking mycelium mass).

Fruiting body = 100% mushroom, where the highest level of beta-glucans are found. Mycelium on the other hand, contains the substrate that the mushrooms grow on (wood, rice, oats, grains), aka fillers.

HOLY CAP is designed to be versatile and applicable for any type of diet you feed your pet!
