Who Manufactures Ultimate H2™?

Ultimate H2 is manufactured by Gundry MD. It is a renowned brand founded by Dr. Steven Gundry, who is a well-known Cardiologist and Subject Matter Expert in health and nutrition. This brand is recognized for producing premium supplements that are committed to improving the health and well-being of their users.

How Does Ultimate H2™ Work?

The Ultimate H2 tablet offers a potent dose of molecular hydrogen that provides the most potent antioxidant benefits. Molecular Hydrogen is clinically proven to penetrate deeply into the cells and eliminate oxidative stress to promote Mitochondrial health.

A study published in the National Library of Health, cited by Front Physiol and 119 others, states that Hydrogen has a relatively small molecular mass, which helps it quickly spread and penetrate cell membranes to exert a wide range of biological effects. It may play a role in the treatment and prevention of a variety of acute and chronic inflammatory diseases, such as acute pancreatitis, sepsis, respiratory disease, ischemia-reperfusion injury diseases, autoimmunity diseases, etc.

Ultimate H2 also contains Citicoline for added cognitive health benefits. Citicoline is proven to improve neural communication to enhance memory, focus, and overall cognitive functions. A 2023 study in the Journal of the National Library of Health supports the claim that oral Citicoline intake positively influences memory function in humans who encounter age-related memory impairment.

The third ingredient of Ultimate H2 is Methylcobalamin (Vitamin B12), which is crucial for the production of cellular energy. A 2013 study published in the Journal of the National Library of Health, cited by Neural Plast. And 184 others show that Methylcobalamin improves nerve conduction, promotes the regeneration of injured nerves, and inhibits ectopic spontaneous discharges of injured primary sensory neurons.

By incorporating Hydrogen, Citicoline, and Methylcobalamin (Vitamin B12), Ultimate H2 not only supports physical energy but also strengthens mental clarity, digestive health, and metabolism to offer an all-around and natural boost in energy and wellness daily.

What Are the Ingredients In Ultimate H2™?

The main ingredients in Ultimate H2™ are:.

Methylcobalamin (Vitamin B12)

It is an activated form of Vitamin B12 that is commonly used in most oral medicines and dietary supplements. Methylcobalamin assists in the efficient functioning of the Neurons (Brain Cells), promotes Nerve health, and the production of Red Blood Cells. In a 2013 study by the National Institutes of Health, Methylcobalamin improved nerve conduction, promoted the regeneration of injured nerves, and inhibited ectopic spontaneous discharges of injured primary sensory neurons.

Citicoline

Citicoline is essential for protecting brain health; it improves mental clarity, focus, and overall cognitive functions. It is also effective in treating depression, Schizophrenia, stroke, Parkinson’s disease, brain injury, Alzheimer’s disease, cerebrovascular disorders, and is also known for ophthalmologic benefits. The Alzheimer’s Drug Discovery Foundation defines Citicholine as the best form of Choline that is absorbed by the brain.

Magnesium

It is the most essential mineral for energy production, oxidative phosphorylation, and glycolysis. Magnesium regulates heart health, blood pressure, cholesterol levels and is highly essential for maintaining bone density and structure. The University Hospitals Organization published a study in 2022 describing the health benefits, deficiencies, and health requirements of Magnesium, including heart health, bone health, metabolic health, sleep, and stress management.

These ingredients work together to provide a comprehensive solution for energy, digestion, and mental clarity.

Tired feeling – I have been taking this for about 2 months so far I think. I have noticed after about 1 hour after drinking this I feel tired. I have attributed this to these tablets since these are the only new thing I have been taking.
