Just a couple of minutes ago (which, by the time I finish writing this post, will have turned into a couple of hours…at least…), I came across an interesting study published in March 2010. Luckily for us, it is fully available online: http://goo.gl/RoC45
First, what is astaxanthin? It’s a carotenoid, which means it’s a tetraterpenoid (=contains 40 carbon atoms) organic pigment…eeeeh? Oh, forget it…Let’s try to find a simpler explanation…
Okay, we know what carrots look like, right? Well, their bright orange color is caused by a carotenoid. Another carotenoid is lycopene, which can be helpful in preventing the onset of prostate cancer and is found in tomatoes and other red fruit/veggies (not strawberries or cherries, though).
This article actually gives us some fascinating titbits, such as the fact that flamingos are really born white, and it is astaxanthin that gives them their “pink look”: http://goo.gl/C5ruc After reading the above-mentioned study, though, I would like to state that the astaxanthin dosage mentioned here by Dr. Mercola seems a bit too high to me (I wouldn’t go above 2 mg, for reasons we will see in a sec…)…
Let’s see. I read on other websites that the highest levels of astaxanthin can be found in algae. I also read that some commercial sources of astaxanthin include shrimp processing waste…ewww! And here is another ewww!: it can also be produced synthetically (much cheaper, this way), which means that it might contain some extra stuff that might not be so good for us. So, if we decide to give this substance a whirl, we must be careful when choosing our sources…
Okay, here is what we know thus far: astaxanthin is a powerful antioxidant with powerful anti-inflammatory activity. As such, it might be useful to treat heart, immune, inflammatory and neurodegenerative diseases. More to the point, it might be useful in the prevention and perhaps even treatment of cancer…
I didn’t find any astaxanthin and myeloma studies in PubMed, but that didn’t keep me from doing a bit of research on astaxanthin, which seems to hold some promise as an anticancer substance…
If you check out PubMed, you will find, in fact, that astaxanthin has been studied in other types of cancer, e.g. breast cancer, where it delayed tumor growth and modulated immune response: http://goo.gl/CHMp8 This study is interesting, since it shows that astaxanthin was useful in the prevention of breast cancer. However, when administered after the onset of cancer, it seemed to be harmful. This reminds us that we should always be super careful, do our research carefully and talk to our doctors before taking anything…and always monitor our blood test results…
Administration of astaxanthin was shown to be beneficial in canine osteosarcoma: http://goo.gl/SVlnE
Last but definitely not least: http://goo.gl/qxcJG This study shows astaxanthin decreased the levels of MMPs (2-9), ERK-2 and Akt. These three proteins are involved in myeloma, too…quelle surprise. You can do a search of my blog for all three…but, for example, MMPs are enzymes involved in bone destruction and cancer growth…need I say more? Astaxanthin decreased the serum levels of these three proteins in rats with colon cancer…and it also lowered their levels of NF-kappaB, which is one of the big criminals in myeloma, too…So this finding is verrrrry interesting…
Okay, there are other PubMed studies, but I will stop here before this post looks more like a laundry list than a proper post. Let’s now have a look at the randomized, double-blind, placebo-controlled study that prompted this post in the first place (see the first link in this post…).
Results that I thought were interesting and possibly relevant to MGUS, SMM and MM folks:
- C-reactive protein levels decreased in the volunteers taking 2 mg of astaxanthin. Good news. Note that the higher, = 8 mg, dosage didn’t have a further lowering effect on CRP, which just goes to prove once again that too much of a good thing might not necessarily be…a good thing.
- Astaxanthin increased the activity of Natural Killer cells, and also T and B cells. It increased the immune response in these healthy college-age women.
- Concentrations of something called “8-OHdG” (=a DNA-damage biomarker that could be a risk factor for cancer and atherosclerosis, among other nasty things) were significantly lower in the 2 mg group. Not sure how relevant this bit of news would be to folks who already have cancer…but surely it would be a good thing to decrease those DNA-damaging levels, no?
- Those taking 8 mg of astaxanthin had increased levels of IL-6…Not good. Again, too much of a good thing blablabla…So, if I were to decide to take astaxanthin, I would keep to a low dosage, not the 10 mg one suggested by Dr. Mercola.
- A 200-g serving of salmon provides approximately 1 to 7 mg astaxanthin.
In conclusion, it seems that 2 mg of astaxanthin might be a good thing to test, but I have so many other substances gathering dust on my cabinet shelf that I probably won’t be buying anything new for a while…
Still, it’s good to know about these new discoveries…and keep an eye on ‘em!
