Xetina 20 Reviews – Should You Buy Simple Promise Eyesight Support Formula?

Vision is one of those things that people usually take for granted. We seldom ever take the time out of our busy days to appreciate how we might communicate with others and see the world. Only when our vision is impaired do we realize how well we used to see and how much worse it has become. When such awareness takes form, there is usually only so much that can be done to change the situation. Living with decreased vision can be a terrible challenge. Why? For starters, individuals will have to learn to navigate through life’s day to day activities with this new hindrance.

Sure, prescribed glasses exist for a purpose, but admitting that things are changing makes it more difficult for some to wear them. Normally, the recommended solution is usually some type of surgery, either minor or serious. Surgery as the first answer will certainly be intimidating because it is dangerous and has a number of potential side effects. Rather than having to fight too late into the game, individuals may wish to protect their eyes from the get-go, especially those with mild vision impairment. How so? This is where it is fitting to introduce Xetina 20™.

What is Xetina 20™?

Xetina 20™ is an eye health supplement that works to restore, improve, and maintain optimal eye health naturally. Each serving’s contents are trusted to ensure healthy blood circulation to the retina, promote strong blood vessel walls within the eyes, support moisture levels, and alleviate symptoms associated with vision-related diseases. These benefits may be shocking to people who are new to taking supplements.

Doubts are not surprising, given how society has traditionally supported surgical procedures to improve eye health. In truth, certain nutrients originating from natural sources have a better effect, particularly over the long run. Next, we’ll look at the ingredients to see if the Xetina 20™ proprietary blend fits the description.

What does the Xetina 20™ formula mainly comprise?

Each Xetina 20™ serving celebrates a 481mg proprietary blend of:

Xetina 20 Supplement Facts

Lutein & Zeaxanthin

Lutein and zeaxanthin are described as two of the most carotenoids, or pigments produced by plants. There are two key reasons for this: they are powerful antioxidants and are well-known nutrients for eye protection. In particular, this pair of antioxidants has the capacity to neutralize free radicals. When the eyes are exposed to too much oxygen and light, dangerous oxygen free radicals take shape. Fortunately, lutein and zeaxanthin have been shown to cancel out the aforementioned production.

Additionally, they operate as a shield against excessive light, may protect against age-related macular degeneration (AMD), which can lead to blindness, slow the production of cataracts, lower oxidative stress markers, and eliminate inflammatory situations in the eyes. Besides the eyes, lutein and zeaxanthin may protect the skin from sun damage.

Alpha Lipoic Acid

Alpha lipoic acid (ALA) is a naturally occurring chemical present in our cells’ powerhouse, the mitochondria. To put it another way, ALA is essential for energy production, absorption, and digestion. It also has a high concentration of antioxidants, which, as previously said, are vital for protecting the body and its many various components from harmful free radicals. With respect to eye health, this ingredient could serve as a therapy for retinopathy. How? The effect of ALA in neutralizing free radicals, ischemia, and oxidative stress aids in vitamin C action while perhaps protecting retinal ganglion cells and capillaries.

Eyebright & Quercetin

Eyebright is an herb that has traditionally been used to treat minor eye conditions like redness and irritation. Such applications are thought to be conceivable due to the availability of flavonoids such as luteolin and quercetin. This duo works together to suppress mast cells that release histamine. Histamine is a chemical that causes allergy symptoms such as a runny nose and watery eyes, thereby making this herb a potential treatment for seasonal allergies.

Preliminary research also suggests that eyebright may help manage inflammation in cornea cells and protect them from sun-related irritation and damage. Though eyebright has not been fully investigated, quercetin has in terms of treating dry eye, keratoconus (thinning of the cornea), and neovascularization of the cornea (growth of the cornea), which is encouraging.


Rutin is a bioflavonoid (or plant pigment) to have qualified for Xetina 20™. One probable explanation for its presence is that it is converted into quercetin in the gastrointestinal tract, which we saw earlier has a positive effect on eye health. Furthermore, it may control blood flow to the retina, something that, as one source emphasized, is required for clear and sharp vision. It may also act as a barrier against blood vessel illnesses in the eyes, such as diabetic retinopathy. Another source added that animal studies have opened doors to rutin’s role in treating macular degeneration, glaucoma and even cataracts.

Taurine is a non-essential amino acid found in high concentrations in the eyes. While the precise role of taurine in the retina is unknown, several studies have found a link between taurine and osmoregulation, antioxidant activity, stress responses, and protein stability, according to one team of researchers. A lack thereof may result in a diminished ability to fight oxidative stress and age-related changes in the retina. Taurine appears to be of assistance by counteracting the effects of oxidative stress and having antiapoptotic (cell death) actions.

Grape seed Extract

Grape seed extract (GSE) is a dietary supplement made from pulverized grape seeds. It is yet another ingredient rich in antioxidants, which are essential for preventing oxidative stress, reducing tissue damage, and managing inflammation. To date, GSE has been found to improve blood flow, improve collagen levels, support the aging brain, improve kidney function, and combat bacterial buildup. Regarding eye health, an article that covered the relationship under question reported GSE’s ability to improve night vision, prevent or slow AMD, and prevent cataracts [9].


Lycopene is a carotenoid, like lutein and zeaxanthin. Based on the research found in one source, this ingredient naturally promotes eye health and visual acuity. In fact, lycopene’s anti-inflammatory properties and ability to reduce oxidative stress are attributed to the overall health and function of our eyes. Since this carotenoid accumulates in the eyes, it is generally believed to protect people from developing glaucoma, AMD, and cataracts.


Bilberry is a fruit that looks similar to blueberries but differs in numerous ways in terms of its overall composition. It includes a high concentration of antioxidants, which are thought to reduce inflammation and may be used to treat glaucoma, cataracts, dry eyes, AMD, eye weariness, night vision impairment, and retinitis pigmentosa (or a disease of light in the sensitive area of the eye). Keep in mind that these outcomes are primarily based on initial investigations, the majority of which lacks an adequate sample or replicability of results. Therefore, confirmations cannot be established until more research is available.
