Looking for one supplement that works on several different pathways? You might want to take another look at astaxanthin.
I used to take astaxanthin with my testosterone boosting supplements because of a study showing that it can increase T levels (when taken along with saw palmett0). I’ve switched to taking taking astaxanthin along with my NAD boosters in the morning because of recent research showing that it activates AMPK and autophagy,. See article: NAD boosters
Astaxanthin is naturally present in products such as wild (not farmed) salmon and krill. However, much of it has been removed from commercial krill oils.
It’s sold in both powdered and liquid forms. I buy BioAsta’s liquid astaxanthin, (in capsules) and have found it to be much more effective than the powdered kinds.
One interesting side effect is that if you take it for several weeks, it will give your cheeks a slightly rosy color. In nature, it’s what gives salmon its bright orange hue, and makes pink flamingoes pink. It’s also thought to give salmon the endurance they need to swim upstream when spawning.
- One of astaxanthin’s most striking effects is that it improves learning and cognition, and might possibly prevent or slow the progression of demential “Xue and co-authors evaluated the efficacy of AST treatment after repeated cerebral IR injury in a mouse model. These researchers demonstrated that astaxanthin improved learning and decreased memory impairment and neuronal damage. Astaxanthin treatment increased the number of pyramidal neurons of the hippocampus and restored normal neuron morphology….” See full article: On the Neuroprotective Role of Astaxanthin: New Perspectives?
- Astaxanthin protects against UV light damage, including sun damage, in healthy individuals (human study). “To the best of our knowledge, this is the first report to show the effects of dietary supplementation with astaxanthin on MED and the maintenance of moisture in an irradiated area in healthy subjects. The beneficial role of astaxanthin for skin has been analyzed in several human studies [22,23]. Especially for UV-induced skin deterioration, the protective role of astaxanthin against UV ray have been reported both in vitro and in vivo. Furthermore, the effects of dietary supplementation with astaxanthin on UV-induced skin color change were previously reported . Although a relatively late stage of UV-induced change of skin condition including darkening was analyzed, the effects of dietary supplementation with astaxanthin on the early stage of UV-induced skin change including MED was not reported. We found that dietary supplementation with astaxanthin increased the MED and attenuated the UV-induced decrease of moisture in healthy human. These results demonstrated the protective role of dietary supplementation with astaxanthin against UV-induced stimuli and its usefulness for the maintenance of healthy skin. ” See article: The Protective Role of Astaxanthin for UV-Induced Skin Deterioration in Healthy People—A Randomized, Double-Blind, Placebo-Controlled Trial
- Astaxanthin activates the AMPK pathway, suppresses mTOR and stimulates mitochondrial biogenesis. See article: Astaxanthin stimulates mitochondrial biogenesis in insulin resistant muscle via activation of AMPK pathway
- Astaxanthin activates autophagy (in animal studies). See article: Effect of Astaxanthin on Activation of Autophagy
- Astaxanthin suppresses myocardial injury and is cardioprotective. See article: Astaxanthin suppresses lipopolysaccharide‑induced myocardial injury by regulating MAPK and PI3K/AKT/mTOR/GSK3β signaling
- Astaxanthin protects against organ injury from sepsis (in lab animals) See article: Protective effect of astaxanthin against multiple organ injury in a rat model of sepsis
- There’s evidence that it protects the eyes against UV damage and can be effective as a treatment in ocular diseases. See article: Clinical Applications of Astaxanthin in the Treatment of Ocular Diseases: Emerging Insights
- There’s evidence that it’s effective in reducing fine-line skin wrinkling. See article: Fight The First Signs Of Aging With Astaxanthin
