Today we will be talking about a product you may have heard of. This product is L Carnosine. Now I just want to point out that in this blog I will be talking about L Carnosine not Carnitine. While these nutrients sound similar they are quite different and have different uses.  Having said that lets get into it, shall we? So what exactly is L Carnosine? Basically it is an amino acid that is naturally produced by the body. (1)

L Carnosine has been found to be anti- cataractogenic. One theory is that this ability is because of the antioxidant properties that L Carnosine has. Additionally studies have found that L Carnosine offers a “new prospective treatment for diabetic cataracts”. (2) Other studies have found that the antioxidant benefits of L Carnosine may help to “improve the quality of vision and length of life” for diabetics. (3) Other studies have that the ability of L Carnosine to act to restrict glycation may help with reducing diabetic eye disease. (4)

Moving on from diabetic eye disease and cataracts studies have found that L Carnosine can help with other eye conditions. In fact one study found that formulas that contain L Carnosine can statistically reduce eye pressure as well as improve both light and contrast sensitivity. (5) Other studies have found that in those with glaucoma L Carnosine may have a neuroprotective effect. (6)

In addition to helping with the eye concerns previously mentioned studies have found even more visual benefits for L Carnosine. In fact studies have found that L Carnosine has neuroprotective potential especially for those who have macular degeneration. (7)

While Invite Health’s L Carnosine Plus obviously does have all these benefits of L Carnosine there’s that little word at the end, Plus. What does the added Plus really mean? It means that there is more than just L Carnosine in our formula! First let’s talk about Quercetin. Now I know your most likely thinking but Dr. Claire isn’t that just for allergies?  When you heard the word quercetin you probably thought of allergies. But it does much more than just help with the things you may have heard about in the past. What even is quercetin? It is a natural antioxidant. It also has powerful anti- inflammatory and anti-fibrous properties. Studies have found that it can be helpful in corneal diseases such cataracts and keratosis (this is where the cornea becomes thin and bulging). Many people with the thyroid disorder Graves’ disease experience what is known as Graves’ ophthalmopathy (in laymen’s terms this is where the eyes seem to “pop out”). Studies have found that quercetin may help with this condition. Additionally studies have found that quercetin may help with dry eye, retinopathy and even conjunctivitis. (8)

The next nutrient is rutin. Rutin is a nutrient that is well known to help regulate blood flow and even help to support blood vessels. This is critical for eye health since blood flow to the retina is so important. One disorder rutin is thought to protect against is diabetic retinopathy. Rutin can also help prevent what is called subconjunctival hemorrhage. One study found using formulas that contain rutin for 40 days can reduce eye pressure an average of 20%! In another study eye pressure dropped by 10% after just 3 weeks of use! As you can see rutin is an excellent eye nutrient. (9)

Lastly L Carnosine Plus also has B1 which has been found to help with dry eye. (10) L Carnosine Plus has so many health benefits. In this blog I just focused on eye health. But L carnosine has so many additional benefits that it totally rates as a “top seller”!  Our next topic will be Diabetic Retinopathy.
