Best Value Pure and High Potency Astaxanthin 8mg 180 Capsules - Supports Antioxidant Health - Made in USA GMPC - Guaranteed Purity

excellent

I had earlier purchased Astaxanthin from Sports Research and the results were kinda in the face. I was quite impressed with it that I purchased another bottle when I finished the first one. It was my mistake to assume that all brands will have similar quality going by the dosage alone. This one does not show much of effect on skin or joints while with Sports Research Asta it was very noticeable. I've probably had 20 of the 180 caps. not sure if having the rest will help much ! Will not purchase this brand again.

When I first saw the price and amount of pills you get for the price, I was a bit skeptical, but it was so inexpensive compared to other brands I figured it was worth a shot. I am very glad I did, and I will continue to purchase. I am a lifelong martial artist in his 50's and experiencing aches and pains in the hips and back. I used to joke that I would keep training "until the wheels fell off". That time felt like I was about there. I've been using this supplement for about 2-3 weeks and I must say the pain has greatly diminished and "the limp" is reduced. The grinding pain does not wake me up at night anymore. I have noticed my head is clearer, I have more stamina, and I am in a better mood. I have a regimen of supplements I take, (C,D, Tumeric, MSM, shark cartilage, DMSO, Fish oil, MCT, ACV, CBD, C60 oil, and Aleve), but nothing has been as effective as Astaxanathin. I am taking less NSAIDs as a result, which I was taking daily. I am down to maybe a few times a week of Aleve. If I ever decide to stop taking the rest of the supplements, I will not stop the Astaxanathin. Great product.

I've taken only 5 and so far no noticeable lessening of specific symptoms or general sense of well being. it's early and i'll continue taking them. my beef is, and it is huge for me, is once I opened the lid the bottle was not sealed. and even more disturbing, when I closed the cap it was very loose and letting in air. I put some plastic wrap around the lid and closed the lid which helped seal and protect any air from the capsules, but this needs refigured. I'm used to supplements and vitamins having an initial seal under the cap and having an air tight sealed cap.

The product is misleading in its labeling (4 mg caps yet makes it look like 8 mg). The source is not clearly identified on line.Product description fails to describe whether the product is synthesized (as is nearly all commercial product used for aquaculture) or obtained from natural sources, micro algae, phaffia yeast or krill. Phaffia yeast exhibits 100% free, non-esterified astaxanthin, which is considered advantageous because it is readily absorbable and need not be hydrolysed in the digestive tract (of fish). In contrast to synthetic and bacteria sources of astaxanthin, yeast sources of astaxanthin consist mainly of the (3R, 3’R)-form, an important astaxanthin source in nature. Finally, the geometrical isomer, all-E, is higher in yeast sources of astaxanthin, as compared to synthetic sources. This contributes to greater efficacy because the all-E (trans) isomer has greater bio-availability than the cis isomer. Astaxanthin has two chiral centers, at the 3- and 3′-positions. Therefore, there are three stereoisomers; (3R,3′R), (3R,3′S) (meso), and (3S,3′S). Synthetic astaxanthin contains a mixture of the three, in approximately 1:2:1 proportions. Naturally occurring astaxanthin varies considerably from one organism to another. The astaxanthin in fish is of whatever stereoisomer the fish ingested; that produced by Haematococcus pluvialis, which is commonly used in animal feed destined for human consumption, is the (3S,3′S) stereoisomer. The primary use for humans is as a dietary supplement. Due to its higher bioavailability, the yeast source ((3R, 3’R)-form) is preferable. On careful close inspection of the fine print on the product label this product is identified as from haematococcus pluvialis. Based on a careful review of peer review literature its bioavailability appears to be inferior to the yeast product. This must be crtically evaluated as bioavailability (absorption) is also related to several other factors. My point is this is touted as highly available with no qualification. Currently the avg price of Haematococcus pluvialis astaxanthin is about $150/Kg, or $0.15/mg. The bottle contains 180, 4 mg caps or 720 mg at for a total product cost of $10.80. The product is recognized as a dietary supplement by the FDA, so there are no regulatory hurdles. At $18.99, that is a 90% profit. As a a businessman I recognize we are in business to make money, but I loath misleading labeling and marketing practices. If you have a quality product say so. Clearly identify its source and be open about its quality. I don't mind paying as long as I know what I am getting.
