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.

Good value for 12mg Astaxanthin

Size: 30 Count (Pack of 1)

Long time user of Astaxanthin so can’t say if this particular one made a difference but I can say it’s a good value compared to a majority of other brands considering you get 12mg; like most the capsules are easy to swallow. I feel like since this is Amazon’s own brand there’s less risk of receiving an imposter product as can be an issue with some brands. I suggest stocking up when there’s a promotion.
