These compounds are required for the synthesis of DNA as well as for protecting the body against infections and cellular damage. Selenoproteins also control the metabolism and reproduction of thyroid hormones.

Cataplex E2 is staple supplement for cardiovascular health. It’s especially effective at high altitudes, keeping you going when you start having altitude sickness. It’s also good for flying. It’s extra nutrients for your blood, so can be benefical for healing up as well as general health. Like all Standard Process products, it’s best to let your nutrional / homeopath Dr. recommend what supplements are best for your situation. I’ve been using Standard Process for years. They are the best of the best.

Have you tried this product?

Since I live at 5000 feet and quite frequently suffer from shortness of breath I decided to give it a try! All I can say is that the mountain climbers are right, it works fast and I love it!

Patricia D. Hoyt

Perfect source of natural and complete vitamin E. Along with other Standard Process products keeps the old heart ticking as it should.


Cataplex E is a great supplement but it is not in any way a homeopathic remedy as stated in this article.

I take Cataplex E every spring and autumn to build my immunity and for it’s powerful antioxidant properties. I rarely catch a cold, and when it happens, I’m back on my feet in a couple of days. I used to be a sickly person by nature, so I’m more than happy with the effects.
