VISTRA Astaxanthin 8 mg Ultra Plus

The ingredient list on the label answers this. VISTRA softgels declare the capsule shell as INS 428, which is the international code for gelatin, so it is animal-derived. Products declaring INS 464 use hydroxypropyl methylcellulose, which is plant-derived. Some products also use the colour INS 120, carmine, which is obtained from insects, so anyone avoiding animal-derived material should read both points on the label.

Every dietary supplement sold in Thailand must show a 13-digit food registration number on the label, for example 13-1-00449-5-0243, and it can be checked against the Thai FDA public register at porta.fda.moph.go.th by searching that number. Each product page on this site shows the registration number for that product, so it can be compared directly against the pack you have.

This site is a brand information site and does not sell products directly. Each product page carries a Where to buy button showing the outlets that stock that product. Price and availability are set by each retailer, and some products and pack sizes are not available in every outlet.

Keep them in the original sealed container, away from sunlight and heat, as stated on the label. Humidity and heat affect the stability of several ingredients: astaxanthin degrades with light, heat and oxygen, and fish oil reacts readily with oxygen. Do not refrigerate unless the label says to, because moving a container in and out of a fridge causes condensation inside it.

Astaxanthin is a red-orange xanthophyll carotenoid obtained from the microalga Haematococcus pluvialis, and it is the same pigment that makes salmon flesh and shrimp pink. In chemical terms it is classified as an antioxidant carotenoid.

Yes — every VISTRA product is a dietary supplement registered with the Thai FDA. The registration number appears on the label and on this page.

No. This is a dietary supplement, not a medicine — it has no effect in preventing or treating any disease. Read the label before use.
