What is astaxanthin powder?

Astaxanthin bulk powder is a naturally occurring carotenoid pigment that is found in certain types of microalgae, yeast, salmon, trout, krill, shrimp, crayfish, crustaceans, and some types of seaweed. It is a red-orange pigment that is responsible for the pink color of salmon and the red color of cooked lobster. astaxanthin has been studied for its antioxidant properties, and it is believed to have a variety of health benefits, including reducing inflammation, protecting the skin from UV damage, and improving cardiovascular health. astaxanthin is commonly available in supplement form as a bulk powder, which can be added to food or drinks or taken as a standalone supplement. It is also used as a natural food coloring agent in certain products.

Astaxanthin bulk powder specification

Astaxanthin for Fish

Astaxanthin is a powerful natural antioxidant widely used in aquaculture to support fish health, growth, and pigmentation. It is commonly added to the feed of salmon, trout, shrimp, tilapia, ornamental fish, and other species to improve overall performance.

Key Benefits for Fish

Enhances Pigmentation: Astaxanthin gives salmon, trout, shrimp, and ornamental fish their bright red–orange color, improving appearance and market value.

Boosts Immune System: Helps fish resist infections, stress, and environmental challenges.

Supports Growth & Survival: Improves feed efficiency, metabolic activity, and overall vitality.

Powerful Antioxidant: Protects cells from oxidative stress, improving health during high-density farming.

Improves Reproductive Performance: Supports egg quality and fry survival in broodstock.

Recommended Inclusion Rates

*Actual inclusion rates should be adjusted according to the astaxanthin concentration (e.g., 1%, 2%, 5%, or 10%) and local feed regulations.

Best Practices

Mix evenly to ensure consistent intake.

Avoid prolonged exposure to high temperatures during feed processing whenever possible.

Combine with other antioxidants, vitamins, and nutritional additives for enhanced performance.

Follow the manufacturer's specifications for the specific astaxanthin product being used.

Note: If you are using natural Astaxanthin Powder from Haematococcus pluvialis, the dosage will differ from synthetic astaxanthin because products vary in astaxanthin content (e.g., 1%, 2%, 5%, or 10%). Always calculate the inclusion rate based on the active astaxanthin concentration.

Astaxanthin powder use

Astaxanthin bulk powder PH value: Rhodococcus lives in fresh water and has a weak buffering capacity for pH. during the cultivation process, the pH value of the solution will rise rapidly with the absorption of nutrients, and the pH value is often >10. pH becomes the limiting factor for Rhodococcus growth. Controlling pH is one of the keys to solving the slow growth of Rhodococcus. Haematococcus pluvialis, especially its green swimming cells, is more sensitive to changes in environmental pH, and its growth state is closely related to the pH stability of the medium.

Astaxanthin bulk powder is added to shrimp feed to help shrimp add color. astaxanthin also helps to enhance the anti-stress ability of crustaceans, is a potent antioxidant, and is an additive that improves growth performance and color stability in many aquatic animals.

Crustaceans can convert many carotenoid pigments, such as beta-carotene, into astaxanthin. for example, lutein, a natural carotenoid that is much cheaper than astaxanthin, can be extracted from some vegetables such as marigolds. In support of this idea, a recent study by the HJHERB R&D team showed that the addition of 200mg/kg lutein to the feed improved the growth performance, immunity, and total carotenoid content of different tissues of macro brachium japonicus.
