Yes, astaxanthin is also considered as one of the best antioxidant for our body, I watched the video at http://products.mercola.com/astaxanthin/ which subjects tackles more about the advantages of astaxanthin through the whole body.
One of the *dangers* of being on this kind of regimen is that we are likely to ascribe an effect/lack of effect on the supplements that we are taking rather than looking at diet/lifestyle as a whole.
This may or may not apply to you, if not, surely others can benefit.
Too much D? not enough calcium? No means of calcium transport? food for thought...
Are you taking your cod liver oil? Do you use olive oil? Eat fatty fish?
This is from a book entitled "empty Harvest". I disagree with the emphasis on PUFAs here, but it's a good explanation on the importance of fatty acids in calcium transport(and the ability of the skin to resist solar radiation). Vitamin "F" refers to PUFAs. We all know that PUFAs suppress the thyroid... The most important sentence in the text:
~~~~~~ Thus, if you're eating margarine; if you're eating oleo products, hydrogenated oil products; if you're cooking the life out of your oils; you're not getting the vitamin "F" factors. Then, even if you have calcium, you're not going to put it into the skin to protect the skin against solar radiation." ~~~~~~~~~~~~~~~~
"The problem here is, we've torn holes in our own ozone layer- a good symbol of our current conciousness. One of the things to keep in mind is that to keep the flesh from being totally susceptible to the effects of ultraviolet radiation, the skin needs to be strong and hard. Skin is our body's most outer defense.
People have so little strength in their skin because of their vitamin, fatty acid & mineral deficiencies- which go all the way back to the soil...There are so few trace elements in the demineralized soil, the skin of the Earth, that likewise the skin of the people who live upon it is made even more susceptible to the effect of ultraviolet light...
...the vitamin that controlled calcium absorbtion into the blood had a natural antagonist, unofficially called vitamin "F". What vitamin do we get from the sun? Vitamin D. It is important to understand the relationship between vitamins and minerals because they are entirely different substances....Minerals obey one primary physical law: gravity..Vitamins help control the flow of minerals through the body. Vitamins help control the metabolism & utilization of minerals.
Calcium cannot get through the gut and into the bloodstream without vitamin D."
CALCIUM CONTROL, SUBURN, AND YOUR SKIN
"What makes vitamin D potentially toxic is that it is capable of elevating the blood calcium level so high that blood viscosity becomes dangerously high, laden with heavy calcium molecules. The bone-building mineral, calciuum, in excessive amounts, can thicken the blood and reduce capillary circulation. The reason calcium is in the blood, as with most nutrients, is for transportation...
Vitamin "F", which we now know consists of essential polyunsaturated fatty acids(linoleic, linolenic & arachidonic acid) ionizes the calcium to transport it OUT of the blood and INTO the tissue.
When the vitamin "F" complex is in the blood, it ionizes and polarizes the calcium molecules, then the calcium flows out of the blood into the tissue. Vitamin D deionizes calcium; Vitamin "F" ionizes it. This results in decreased blood calcium & increased tissue calcium.
Most people have limited amounts of ionizable calcium in the body because they depend on pasteurized dairy foods for their calcium. Then, when they take a vitamin D supplement, their blood calcium levels begin to build up. But the calcium has no means to be drawn into the skin. The skin, very deficient in calcium, has lost it's hardest mineral protection against the sun.
Calcium isn't just for the bones; calcium adds to every tissue exactly what it adds to the bone; strength and structure. Calcium adds strength and structure to every cell in the body, particularly the skin, which is the largest organ of the human body. The skin is a big user of calcium. Thus, if you're eating margarine; if you're eating oleo products, hydrogenated oil products; if you're cooking the life out of your oils; you're not getting the vitamin "F" factors. Then, even if you have calcium, you're not going to put it into the skin to protect the skin against solar radiation."
A new review of the medical literature indicates that omega-3 fatty acids can protect the skin from the inflammatory response caused after sun exposure and that these fish-derived nutrients can reduce the risk of non-melanoma skin cancer.
Researchers at Baylor College of Medicine in Houston Texas analyzed human and animal studies conducted over the past 15 years on the effect of fish oil or fish consumption on sun damage and sun exposure. Their findings indicated omega-3 fatty acids have an important role to play in reducing the damaging effects of sunburn.
In experimental animal studies, the reviewers noted, there is direct evidence that dietary omega-3 fatty acids inhibit the cancerous changes that occur after ultraviolet radiation, including decreasing tumor growth and reducing tumors’ ability to multiply. However, equivalent levels of omega-6 fatty acids increase the cancerous changes that occur after exposure to ultraviolet radiation. In mice and in human skin exposed to ultraviolet B radiation, dietary omega-3 fatty acids dramatically reduce levels of prostaglandin E synthase type 2 (PGE(2)), an inflammatory messenger chemical that suppresses immune response to pre-cancerous cell changes. Dietary omega-6 fatty acids increase levels of PGE(2). In humans, omega-3 fatty acids also increase the time it takes to become sunburned, the review concluded.
The review authors also outlined the negative effects of omega-6 fatty acids, which, when consumed in large quantities act as pro-inflammatory substances. Omega-6 fatty acids are found in margarine, vegetable oils such as corn oil, safflower oil, and salad dressing. Americans consume omega-6 fatty acids in amounts 20 to 40 times too high compared to their omega-3 intake. There are a number of good fish oils on the market, but one of the best new ways to get omega-3 polyunsaturated fats is from krill oil.
In toto, there is strong circumstantial evidence from both experimental and clinical studies to support a role for omega-3 FA in the prevention of non-melanoma skin cancer (NMSC). In experimental animal studies there is direct evidence that dietary omega-3 FA inhibits ultraviolet radiation (UVR) carcinogenic expression, with regard to both increased tumor latent period and reduced tumor multiplicity. Equivalent levels of omega-6 FA increase UVR carcinogenic expression. Dietary omega-3 FA dramatically reduces the plasma and cutaneous pro-inflammatory and immunosuppressive PGE(2) levels in mice. Dietary omega-6 FA increases prostaglandin E synthase type 2 (PGE(2)) level. Dietary omega-3 FA significantly reduces the inflammatory response and sustains, or enhances, the delayed type hypersensitivity immune response in mice when compared to an equivalent dietary level of omega-6 FA. Supplementary omega-3 FA significantly increases the UVR-mediated erythema threshold in humans. Supplementary omega-3 FA significantly reduces the level of pro-inflammatory and immunosuppressive PGE(2) levels in Ultraviolet B-irradiated human skin.
