Lutein 20mg 60 softgels - lutein and zeaxanthin | Jarrow Formulas
Jarrow Formulas Lutein 20mg 60 softgels provides effective levels of the important eye-protecting nutrients lutein and zeaxanthin. Lutein and zeaxanthin concentrate in the eye's macula and lens, as well as in the skin, breast and cervical tissues. Both lutein and zeaxanthin protect the macula from degradation normally associated with aging and oxidative stress.
The macula is responsible for focus and color differentiation. Lutein and zeaxanthin are found in dark green, leafy vegetables. While the average American intake of lutein is only 2 mg per day, other population groups consume up to 20 to 25 mg per day.
who benefits from Lutein?
Adults of all ages who are concerned about maintaining healthy eyes.
what distinguishes Lutein?
• clinically documented eye support
• effective amounts of lutein (20mg lutein per serving) and zeaxanthin
• better stability and absorption with naturally occuring lutein esters
• marigold flower petals are an excellent source of lutein and zeaxanthin
how does each active ingredient function in Lutein?
• lutein is an integral component of luteal pigment found in the macula that must be obtained in the diet. They help protect the retina by absorbing UV radiation and neutralizing free radicals
Two “minor” carotenoids provide major protection
Jarrow Formulas Lutein is a blend of lutein and zeaxanthin extracted from marigold petals and then purified into crystalline form. These carotenoids (a family of brightly colored pigments in plant foods) are less common than their better-known relative, beta-carotene, but they appear to offer more and greater benefits to the body. In particular, lutein and zeaxanthin have been shown clinically to support visual function and to protect the health of eye tissues as we age. In addition, preliminary research suggests that lutein and zeaxanthin may protect the cardiovascular system and maintain normal cell differentiation in the tissues of the breast, cervix, colon and skin
What are lutein and zeaxanthin?
Lutein and zeaxanthin are important antioxidants used by the body for a number of physiological functions. Lutein is a carotenoid which does not supply vitamin A activity to the body. It is chemically distinctive in that it lacks part of the terminal “ring” structure of the other carotenoids. Like its close relative zeaxanthin, lutein is what is termed a xanthophyll carotenoid. Both of these related carotenoids are better antioxidants than is beta-carotene under normal oxygen conditions. Lutein can be metabolized into zeaxanthin and is therefore the more essential carotenoid. Zeaxanthin has been shown to be present in the center of the macula. Lutein and zeaxanthin are usually found together in leafy green vegetables, such as kale, broccoli, spinach and mustard greens.
One of the primary functions of lutein and zeaxanthin is to provide protection against oxidative and free radical damage. These yellow-colored carotenoids are found in high concentrations within the macula lutea (the yellow spot in the center of the retina) and in smaller amounts throughout the retina and the eye lens. They are also concentrated in the skin, breast and cervical tissues. These stores, however, appear to diminish with age if not regularly replenished through dietary means.
Scientists believe that lutein and zeaxanthin contribute to the density of macular pigment –– the component of the eye which typically absorbs and filters out 40 to 60% of damaging near-ultraviolet blue light (near-UV blue light) which strikes the retina. The denser the pigment, the more the inner retina is protected from light-induced damage. Lutein/zeaxanthin also helps limit blue light damage to the inner retina by inhibiting lipid peroxidation and by neutralizing free radicals.
Considerable evidence shows the importance of lutein and zeaxanthin in reducing changes in the opacity of the eye lens as we age. The results of a study published in the British Medical Journal showed that the consumption of spinach maintained eye lens health better than other vegetables, such as carrots, sweet potatoes and winter squash, which contain primarily beta-carotene and very little lutein. Similarly, according to a study published in the Journal of the American Medical Association, people who eat foods rich in lutein — particularly kale and spinach — are more likely to maintain optimal vision. Protection most likely comes from the scavenging of free radicals. Lutein/zeaxanthin prevents peroxidation in the lens, thus limiting damage to the opacity of this tissue.
As is true of vitamin E, but not of other carotenoids, lutein is found in blood plasma at levels correlated with the amount of cholesterol. Tests suggest that although lutein is relatively minor as a component of LDL cholesterol in comparison with vitamin E, its antioxidant protective effects may be ten times greater if compared on a one-to-one basis.
Regulated cell growth
Several studies have indicated that lutein and zeaxanthin may be helpful in protecting cells in various tissues of the body, such as the skin, breast, cervix and large intestine. A 1999 Harvard epidemiological study indicated that lutein is one of the nutrients which is associated with better breast health. Likewise, a study published in the American Journal of Clinical Nutrition found a similar positive association between the consumption of lutein and colon health. Lutein, like lycopene and a number of other carotenoids, would appear to influence the regulation of cell growth and repair.

Are eggs good or bad for diabetes?
Outside COVID-19 very little health news catches the attention of newspapers, unless it is something out of the ordinary.
One such news item was the result from an observational study among Chinese citizens of whom it was reported how those eating more eggs had a higher risk of diabetes 2.
Oh boy, here we go again was my first thought. First eggs were vilified due to their cholesterol content, and now that nonsense has been put to rest [link], they try to come up with another BS research. Yes, calling it BS.
Imagine, you are a notorious smoker and decide to give up smoking because your lungs are suffering and have developed COPD. Yet, it is too late and a lung tumour has been detected. Guess what? The clickbait headlines would go like "people that give up smoking, will develop lung cancer!".
That's how it works! Time and again we have to repeat: correlation is NOT the same as causation. This was an observational study, in which people were asked about their habits.
A much better research method is a clinical study in which people are meticulously followed after treatment.
Or a meta study in which several studies are lumped together and analysed.
Particulate matter and your healthAs the Dutch government decided to move away from natural fossilized energy sources, we are moving towards solar and wind energy.
Because solar and wind energy cannot provide all energy and a decision to also move away from natural gas, biomass plants seemed to be the perfect solution.
Biomass is plant or animal material used for energy production (electricity or heat). It can be purposely grown energy crops, wood or forest residues, waste from food crops (wheat straw), horticulture (yard waste), food processing (corn cobs), animal farming (manure, rich in nitrogen and phosphorus), or human waste from sewage plants.
Burning plant-derived biomass releases CO2, but it has still been classified as a renewable energy source in the EU and UN legal frameworks because photosynthesis cycles the CO2 back into new crops. In some cases, this recycling of CO2 from plants to atmosphere and back into plants can even be CO2 negative, as a relatively large portion of the CO2 is moved to the soil during each cycle.
However, over the past few months it has become clear how a lot of biomass comes from trees, that were previously pristine forests in the USA or the Baltics.
While in the best case, the use of biomass could even be CO2 negative, burning biomass will result in excessive CO2 output locally as well as of particulate matter.
This is why almost overnight, due to negative public opinion, politicians changed their mind. Too late though, there are already few hundred biomass plants that are being constructed due to substantial subsidies that were handed out, so we can expect a substantial worsening of air quality in the upcoming decade(s) because of the increased amount of particulate matter.
What causes night blindness?People with night blindness experience poor vision at night or in dimly lit environments, for which the medical term nyctalopia is used.
Although the term “night blindness” implies that you can’t see at night, this isn’t the case. You may just have more difficulty seeing or driving in darkness.
Some types of night blindness are treatable while other types aren’t. Once you know the cause of the problem, you can take steps to correct your vision.
