We have compiled a list of the most frequently asked questions here, with answers by our panel of experts.

Modern lifestyles may require you to spend long periods of time focusing on objects right in front of you, such as computer screens, books, and televisions. Over time, this can cause vision to become weaker. It is natural for your vision to deteriorate with age, but Yuuto Nutrition have gone to great lengths to source high-quality eye formula supplement to help provide as much support to your eyes as possible.

Yuuto® CRYSTALLINE Vision Enhancement is a premium supplement that, when taken according to directions, will aid in helping infections and other vision related issues associated with the eyes. Packed with vitamins and minerals including Biotin and vitamin C there is an added bonus of a boost to the immune system.


Vitamin B12 – Helps nerve function by supporting the myelin sheath, which insulates nerves such as the optic nerve.* Vitamins C & E are antioxidants that support circulation and
the structures of the eye.*

Lutein and Zeaxanthin – for healthy macular pigment and vision*

Lutein and zeaxanthin are yellow and orange carotenoids found in significant quantities in the macula of the eye. The macula is located in the center of the retina and provides the sharp, central vision necessary for reading, driving and seeing fine detail.

High levels of these carotenoids promote macular pigment density, a key indicator of eye health.* Lutein and zeaxanthin work by filtering out potentially damaging blue light. They also help protect the eyes from unstable molecules (free radicals) that can cause tissue damage.*

Research shows it may help fight eye fatigue, particularly in people who work long hours viewing a computer screen.* Lutein and zeaxanthin also provide a full-spectrum antioxidant support throughout the body by supporting joint, skin and brain health.*

Bilberry Extract – supports the retina*

Bilberries may improve vision in people with glaucoma and reduce eye fatigue and dryness in people working with video display terminals. Bilberry extract may improve visual function by promoting the re-composition of rhodopsin, a compound in the retina that responds to light and communicates with the brain.* Bilberry is also a rich source of antioxidant anthocyanins, which may protect the delicate structures of the eye.* [1,2,3,4,5,6]

Grape Seed Extract – supports visual acuity*

Grape seed extract contains a high percentage of oligomeric proanthocyanidins (OPCs), a type of polyphenol. OPCs have been shown to help people experiencing visual stress from video display units such as computers, tablets and television sets. Studies also show OPCs support retinal sensitivity during dark adaptation, visual performance after glare exposure and visual acuity in healthy people.*

N-Acetyl Cysteine

Recent studies suggest that glutathione may help prevent eye diseases. This natural antioxidant produced by all living cells has an important role in protecting our eyes. This is true for people of any age, but especially for those approaching their 60’s or 70’s as levels of glutathione tend to diminish with age.*

Alpha Lipoic Acid (ALA)

This powerful antioxidant is the driving force behind keeping your eyes healthy as they age. Alpha-lipoic acid will prevent age-related eye diseases, most notably, cataracts and age-related macular degeneration.* Whether you are young or old, everyone can benefit from this antioxidant.*

Eyebright – Helps increase the rate of recovery from eye infections, inflammation and pink eye. Eyebright is an herb that improves microcirculation to the retina and helps maintain eye moisture and pressure.*

Quercetin and Rutin – Help support capillary integrity and work with Vitamin C to decrease bruising of the small capillaries in the eye.* Rutin has also been associated with maintaining healthy ocular pressure within the eye.* Quercetin helps support
histamine levels within normal ranges to help maintain eye health.*

  8. Marcelino (verified owner)

    I love CRYSTALLINE Vision Enhancement. So far so good. I’ve been using the product for a short time, but I am feeling more energized since I started my regiment. I am very pleased with this supplement. I notice a change in my vision whenever I forget to take it.

  9. Phoebe

    An affordable high-quality product, would recommend.

  10. David

    I am genetically predisposed to age-related macular degeneration, so I am trying to protect my eyes as much as possible. After a lot of research, to see what is out there, I decided Crystalline is what I was looking for. Thumbs up for Yuuto!

  11. Stephen (verified owner)

    I spend most of my day in front of the computer and I bought CRYSTALLINE to support my vision. I am taking it for 2 months now, and I’ve seen a massive difference: less eye strain tiredness and soreness. Definitely a good product and I will keep purchasing on a monthly basis.

  12. Lydia

    I bought CRYSTALLINE after a work colleague highly recommended. Super product and it really helps with my eye health. Well worth the money!

  13. Christian

    The best eye supplement I have used, reasonably priced.

  14. Paula

    Crystallin is part of my regimen after a treatment for macular degeneration. I will keep using it, very pleased.

  15. Mohammed

    My optician recommended I take this supplement. Already feeling the benefits after a few weeks, I would definitely stick with Crystalline!

  16. Archie Dawson (verified owner)

    I don’t know if this is a placebo effect or if the active ingredients are actually helping my eyes. Either way, I am very happy taking CRYSTALLINE supplement and will continue to take it. It has now been two weeks since I started using it and since I spend a lot of time on my computer, I know that my eyes are really affected by the glare. I use blue light reducing glasses but my eyes still end up dry and irritated. This supplement has made a noticeable difference in how my eyes feel at the end of the day. Thank you.
