XOULTRA is an extra-strength ketone supplement designed to elevate your body into a deeper state of ketosis—where fat becomes your primary fuel source, not sugar.
Formulated with a proprietary, no-sodium blend.

XO8 is an ideal and convenient solution to achieve faster, more effective ketosis, as well as helping to support physical and mental performance.

Programs are professionally
monitored and individually
tailored to ensure lasting success
and efficacy.

Increased mitochondrial efficiency
can lead to increased energy
production and improved
cognitive performance.

BHB ketones have been shown
to reduce neuronal damage and
promote the growth and survival
of neurons.

The BHB acid combined in XO Ultra produces rapid and higher peak ketosis than BHB electrolytes alone.

BHB helps support synaptic
plasticity — which not only enhances memory formation, but reduces oxidative stress and inflammasomes

Patients using XOULTRA
consistently report feeling
mentally sharper and
emotionally calmer.
“Prior to starting Keto5 Ketones, I was in extreme pain with a torn labrum and osteoarthrosis in my hips. I feel so good, and my pain is reduced such that I canceled my surgery. This is huge as I couldn’t get in and out of a car easily. Now I can. I am not a suggestible person; this is real.”

As a breast cancer survivor, I faced a whirlwind of challenges after being prescribed anastrozole to block estrogen following my treatment. Before this, I had been optimized on hormone replacement therapy (HRT), so the shift was nothing short of extreme. Within just eight weeks, I gained 20 pounds, battled severe joint pain, and was overwhelmed by hot flashes, intense cravings for unhealthy foods, brain fog, mild depression, short-term memory loss, sleepless nights, and a complete lack of energy. It felt like every part of my life was unraveling, and when I turned to my oncologist for help, I was told it was just menopause and that there was nothing to be done. I felt stuck, like my quality of life was slipping away. Then, everything changed when I received a sample of XOImmune. From the very first dose, it was like a lightning bolt of clarity and vitality hit me. I had energy again, and my mind felt sharp—I could actually think clearly! Within a week, I noticed remarkable improvements: I lost 5 pounds, my joint pain dropped from an 8 to a 2, my cravings for unhealthy foods vanished, my depression lifted, and I started sleeping better. It was as if I was reclaiming my life. Now, 2.5 years later, XOImmune has become an essential part of my daily routine. If I miss a day, I can feel the difference—it’s that powerful. My pain is manageable, my weight is stable, my mood is brighter, and I’m sleeping through the night. XOImmune didn’t just help me cope with the side effects of anastrozole; it gave me back my energy, my clarity, and my joy. I’m beyond grateful for this product. It’s been a true game-changer in my journey as a breast cancer survivor.

Even though I am currently not on a diet I did not gain any weight over the holidays even though I ate like a mad woman.

This product has been game-changing for me. I have more energy and sleep better. Pain level lower and improved focus.
