Good
I love these! They have a little smell to them but my stomach favors these types of vitamins rather than the chalky ones.

Good pain relief. Fair price and no side effects.
Size: 30 Count (Pack of 1)
I take this for its ability to block interleukin 1b and interleukin 6 and cox 1 and 2 enzymes without side effects or harm to liver or kidneys.
This brand seems to be working well.
I tried the Hawaii brand BioAstin 90 caps for $48 and this brand seems to be about the same price per cap. I have not noticed any difference in quality.
Information:
Astaxanthin works as an anti-inflammatory through multiple pathways. The various mechanisms
of action for Astaxanthin as an anti-inflammatory have been demonstrated in several studies
(Lee, et al, 2003; Ohgami, et al, 2003; Choi, et al, 2008; Kishimoto, et al, 2010). This research
has consistently shown that Astaxanthin works on a variety of different causes of inflammation.
In fact, there is evidence that it works on six different inflammatory markers, but that it works in
a gentle, broad-spectrum manner. This is in distinct contrast to anti-inflammatory drugs such as
Celebrex® and Vioxx® as well as over-the-counter anti-inflammatories such as Non-Steroidal
Anti-Inflammatory Drugs (NSAIDs including Tylenol®, Motrin®, Alleve®, etc.) and aspirin, all
of which target a single inflammatory marker, but in an intense manner. Inflammatory markers
gently reduced by Astaxanthin include:
• Prostaglandin E-2
• Interleukin 1b
• Interleukin 6
• Tumor Necrosis Factor-A
• Nitric Oxide
et al, 2010)
• Cox 1 & 2 enzymes (Lee, et al, 2003; Ohgami, et al, 2003; Choi, et al, 2008; Kishimoto,
Natural Astaxanthin has never been reported to have any side effect or contraindication in
hundreds of medical research studies as well as over 15 years of commercial consumer use.

Astaxanthin
Size: 30 Count (Pack of 1)
1 week - I've been taking this 12mg Astaxanthinand I've experienced no side effects. I've made sure to take this with food. My husband tried it twice and had a stomach ache afterwards, but I've been fine! I'm looking forward to seeing if this supplement helps with my dry eyes & gives me a glow/tan. Will provide an update in a month.

Works very well on my face.
Size: 30 Count (Pack of 1)
I am totally amazed with his supplement. I wish I had taken a before picture. After only a couple of weeks the wrinkles on my face are disappearing. Time will tell if it helps with the ones on my mouth area and near my mouth. The wrinkles on my face and cheeks are completely gone.
