Oxidative Stress

When the balance of oxidants outweighs the balance of antioxidants

What it does

Oxidative stress causes inflammation in conditions such as chronic fatigue, heart disease, cancer, diabetes, arthritis, stroke, Alzheimer’s, Parkinson’s, psoriasis, alopecia, Crohn’s and fibromyalgia. It also accelerates ageing.

Signs and Symptoms

Oxidative stress is hard to directly measure as it affects the entire body in many different ways

Some people may experience

Tiredness, fatigue, accelerated ageing, poor immune function, continual recurring infections (colds or flu), poor memory, brain fog, muscle and joint pain, wrinkles, headaches and slow recovery times.


Your body's defence against oxidants and oxidative stress

What is an antioxidant?

Antioxidants are molecules that remove oxidants from our body and keep us healthy and in balance. There are two main types of antioxidants: (i) Those from food we eat (vitamins, phytochemicals, polyphenols etc) and (ii) natural enzymes that our body makes

Life changing

Seleno Health is incredible! The best quality life changing, body and mind healing effects of the maca has changed my life at an astonishing rate! Now nearly 3 months after being my maca journey I have stopped all pain relief. My fatigue has nearly completely gone and general mood so much higher than it has been in over a decade. Healing my body from endometriosis, this has been the only supplement I'm taking.
The black helps mentally, focus, clarity, while the red and women's blend helps with hormones and other areas.
I can't recommend highly enough to anyone looking for a better way of life. Thank you seleno health for changing my life for the better ❤️😘🙏🤗☺️

Helping my chronic fatigue

My chronic fatigue was reasonably severe and I had to change my life to cope and I also missed out on doing a lot of things. I went to a Seleno health talk at Raw Balance in Taupo and purchased a bag of Seleno maca. I have been taking 1.5tsp everyday since and my life has improved dramatically. Every now and then I have a bad day but it is rare. I have been able to start exercising daily, I can do everything i want to do and my life no longer revolves around cfs. I am extremely happy and have recommended this product to all my friends. Thank you so much !!!

I was so glad i found The Maca Experts as they really seemed to know their stuff. They advised me on what to take and after combining maca for men with some of the red extracts i had big improvements in energy, clarity and vitality. I felt able to be more active and have since lost 15kg. My blood pressure has come down and my libido has gone libido up!! Ive also seen improvements in my prostate with the red sachets, can sleep through the night easily now without needing to get up to urinate. Wow this stuff really works
