Asta-Marine® (Marine Astaxanthin)

Evidence Level
Limited
1 Clinical Trial
3 Documented Benefits
2/5 Evidence Score

Asta-Marine® is a marine-source astaxanthin, the red carotenoid antioxidant produced by microalgae and concentrated up the marine food chain. The research cited on this page is about skin: a 2021 review pooling 11 studies of generic astaxanthin reported improvements in skin moisture, elasticity and wrinkle depth. No published study has tested the Asta-Marine brand itself, and the cited review measured no eye or exercise recovery outcome.

Studied Dose Studies of generic astaxanthin have commonly used 4 to 12 mg per day. There is no published trial of Asta-Marine itself, so no brand specific dose has been tested.
Active Compound Astaxanthin, a red carotenoid antioxidant, typically from Haematococcus pluvialis microalgae.

Benefits

Skin health

This is the one benefit with cited support. A 2021 review pooled 11 astaxanthin studies in adults (9 randomized controlled trials and 2 uncontrolled open-label studies) and reported improvements in skin moisture, elasticity and wrinkle depth. Those studies used generic astaxanthin, not Asta-Marine.

Antioxidant power

Astaxanthin is a red carotenoid that behaves as an antioxidant in laboratory testing. The single review cited on this page measured skin moisture, elasticity and wrinkle depth, not antioxidant levels in the body, cell protection, eye protection or UV protection, so those specific effects are not shown by the research cited here.

Eye and muscle claims: not supported by the cited research

No research is cited on this page for eye comfort or exercise recovery. The one study behind this page looked only at skin, and it contains no eye, vision, muscle or exercise measurement of any kind. Treat these uses as untested here.

Mechanism of action

1

Singlet-oxygen quenching

In laboratory testing, astaxanthin's structure lets it sit across cell membranes and neutralize singlet oxygen and free radicals. This is test tube chemistry. It has not been shown to translate into a measured health effect in the one human review cited on this page.

2

Anti-inflammatory action

Researchers propose that astaxanthin lowers oxidative stress and in turn quiets inflammatory signaling in tissues such as skin. This is a proposed explanation drawn from laboratory work, not something the cited human review measured.

Clinical trials

1
Astaxanthin and Skin Ageing: Review of 11 Studies (Skin Outcomes Only)
PubMed

Systematic review and meta-analysis of generic astaxanthin, not Asta-Marine, on human skin ageing. It pooled 11 studies: 9 randomized controlled trials and 2 uncontrolled open-label studies. (Zhou et al. 2021, Nutrients)

Adults across 11 pooled studies. Every study used generic astaxanthin supplements; none tested Asta-Marine.

Astaxanthin was linked to improvements in skin moisture, elasticity and wrinkle depth. Skin was the only thing measured: there is no eye, vision, muscle or exercise recovery outcome anywhere in this review. Two of the 11 pooled studies had no control group, so their results cannot be separated from normal variation.

Side effects and drug interactions

Common Potential side effects

Generally well tolerated in the studies done so far, with side effects reported infrequently.
High doses can give a slight reddish skin tint (harmless).
Mild digestive upset is occasionally reported.

Important Drug interactions

Blood thinners: a mild additive blood thinning effect has been suggested, so check with your doctor before combining.
No other interactions have been established, though astaxanthin has not been widely tested alongside medications.
Tell your doctor if pregnant or breastfeeding.
