Catalase is an enzyme that is made in the human liver, and it breaks down toxic hydrogen peroxide (made during cellular metabolism) and turns it into water and oxygen.*  It’s a free radical fighter that protects the cells and precious DNA. It supports skin health, beautiful hair, and skin, as well as liver function.*

May support vibrant healthy-looking hair and skin by allowing for more healthy peroxidation processes* Many people use it because it helps fight “grey and gloom” and other issues resulting from peroxidation.*

Each DR® acid resistant vegetarian capsule contains 12,500 Catu (Catalase units) of Catalase enzyme which is equivalent to 500mg per capsule. 

The formula is optimized to give you the very highest bioavailability. Catalase supplements must be in acid-resistant capsules in order to work. The delicate enzyme is destroyed by your stomach acid, so for that reason, this brand uses DR® capsules. It means this formula works! 


Take 1 capsule daily without regard to meals. This is an enzyme, and you may increase it to 2 capsules (1,000 mg) daily if desired. If you take two capsules per day, you may take them both at the same time.


Q:  When is the best time to take Catalase?
A:  It doesn’t matter, most people take it in the morning. 

Q:  Can I take Catalase at the same time as I’m taking HashiScript since HashiScript has some catalase in it?
A:  Yes, many people like this combination because it works synergistically. 

Q:  Can I take Catalase at the same time that I take my other supplements?
A:  Yes.  Catalase is an antioxidant, so it’s even better if taken with other antioxidants like Vitamin C or D. 

Q:  Are there any “animal-derived” ingredients in Catalase?
A:  No, Catalase is all vegan.  Catalase is NOT derived from animal liver – it is plant-derived.

Q:  What if I miss taking Catalase for a day?
A:  Because Catalase is an antioxidant, if you miss taking it, it’s okay to take it as soon as you remember, or, if you’re only taking it once a day, and you miss a day, then you can take two capsules the next day.

Q:  Is Catalase gluten-free?
A:  Yes

Improves my skin elasticity

I bought it overall for controlling grey hair, can’t tell if it’s slowing down yet, I will give it more time. But what I have noticed is that my skin seems more elastic than before. Some wrinkle areas a lot smoother. I will buy more in the future to continue these results.

Catalase Antioxidant Caps

At this time I’m giving you the 5 stars only because Catalase is suppose to be good for me - I have no way of knowing as I have various issues (which I will not name) and it’s difficult for me to know if anything is helping - with the exception of still being alive!

I have been using this for at least a couple of years and I feel great.

It Works for Me

Catalase works exceptionally well over time. I've been taking it daily for over three years, and there is a noticeable difference when I don't take it. For one, I have few grey hairs as a result. I am in my mid-sixties and don't need to color my hair. That is not genetic.

Catalase brings out the best in my hair color and keeps it feeling thicker and looking shiney. All good attributes at my age!
