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.

Good fiber supplement
Flavor Name: Unflavored, Size: 1.1 Pound (Pack of 1)
Good supplement, wish it came with a scoop. Sometimes there might be a “chunk” that doesn’t dissolve so you get to chew something with your drink, it happens rarely but does happen. Took a while but feel regular and easy to take if you do protein shakes everyday. No taste and mixes well.
