What is GRS Ultra and Is it Legit?

Its absence or presence in lower levels signifies a weaker immunity that may not withstand the onslaught it may be subjected to during real disease attacks.

The supplement is a product of Nutra Active Pvt Ltd based in the state of New York, USA. It mainly comprises clinically proven ingredients guaranteed to give the body with glutathione. 

It is a trusted supplement that has been around for a while and has received thousands of positive reviews from satisfied users.

Here is a brief look at some of the ingredients used in the manufacture of this super supplement. We have also highlighted some of the specific health benefits that come with taking these individual components.

Red Orange Complex – ROC

This substance is found in a variety of Mediterranean oranges and it has always made it to the list of ingredients used in the manufacture of a variety of dietary supplements aimed at boosting the immune system. 

Some of its health benefits include-:

Potent antioxidant activities – clinical studies show that ROC can increase the plasma concentration of biomarkers normally found in antioxidants of endogenous substances like thiolic groups. It can also reduce the levels of oxidative stress biomarkers to the normal physiological range.

N-Acetyl Cysteine – NAC

Cysteine is a semi-essential amino acid that becomes essential when the dietary uptake of serine and methionine is low. NAC is supplementation of cysteine. It is a powerful amino acid that comes with a horde of health benefits, including but not limited to-:

Vital for making glutathione – NAC is highly cherished for the role it plays in the production of glutathione. For glutathione to be manufactured in the body, NAC must be used in conjunction with glycine and glutamine.

Helps in detoxifying the liver and kidney – detoxification is a vital process in getting rid of toxins from the body to prevent the occurrence of a variety of health conditions. NAC plays a very important role in the detoxification process which in turn helps in reducing damage to the kidneys and liver as a result of high levels of toxins in the body.

Improves psychiatric disorders and addictive behaviors – NAC is effective in helping to regulate the levels of glutamate in the body. Glutamate is one of the most important neurotransmitters produced by the brain. It is necessary for normal brain activity. 

When glutamate is available in excess while the levels of glutathione are low, there may be very high chances of brain damage. 

Such an unfortunate combination may lead to a variety of mental health conditions, with the most probable ones being an obsessive-compulsive disorder, schizophrenia, addictive behavior, and bipolar disorder. Studies suggest that ANC may decrease the symptoms associated with depression and bipolar disease. 

Clinical trials also suggest that it may also be used for treating mild to severe OCD.

This is due to its ability to act as an expectorant and antioxidant by helping to loosen the mucus found in the linings of the passageways. 

Also, an antioxidant, it can help in improving the glutathione levels present in the lungs so as to stop the lunge tissues and the bronchial tubes from being inflamed.

Boosts brain health – NAC can boost brain health by replenishing glutathione while at the same time regulating glutamate. Glutamate is a neurotransmitter involved in a variety of learning, memory, and behavior actions. 

Glutathione, on the other hand, regulates the oxidative damage caused to the brain as a result of aging. Since NAC can replenish glutathione and regulate the levels of glutamate, it may help those suffering from brain and memory ailments.

May improve fertility in both men and women – it is estimated that nearly 15% of all the couples trying for a family are usually affected by infertility. 

Nearly half of all these cases are normally attributed to male infertility. Most of the male infertility issues do arise when the level of antioxidant is not sufficient enough to clear the free radicals affecting the reproductive system. 

Studies have shown that NAC can be used to improve male fertility, including those that may require surgery as the primary treatment.
