Vitamins to boost immunity: Astaxanthin

Vitamins to boost immunity: Astaxanthin

18 Feb 2022

There’s an exhaustive list of supplements you can take for various health goals, and sometimes we might be a little spoiled for choice! One nutrient in supplement form that often goes unnoticed is astaxanthin. It has various functions in our bodies, some of which include being a natural antioxidant, acting as an anti-inflammatory agent that reduces free radicals formed in the body, and supporting the immune system.

Astaxanthin is also one of the key vitamins that can support healthy immune system function, and you can take it regularly through diet or supplementation. It is naturally found in organisms that feed on it, such as salmon, and prawn - which is what gives them their red color (1). Let’s get to know the role of astaxanthin in preserving our immune health.

Benefits of astaxanthin in supporting immune health

Here are some of the ways astaxanthin can help support your immunity:

Supports muscle performance

A great way to boost your immune system is by keeping your body healthy through exercise. Astaxanthin can be useful to your exercise regimen as it can support muscle performance and edurance (1). With the effects that astaxanthin has on our muscles, you could improve your exercise performance as well as help your immunity system get stronger.

How to boost your immunity with Astaxanthin

Helps reduce inflammation

Inflammation is part of your immune system response. It  occurs when your body tries to heal itself from things like injuries, toxins, and infections. Whenever you see a wound swelling up or turning red, it’s your body’s immune system’s response to an irritant like a germ or bacteria (2).  

However, too much inflammation can cause damage to the body. Inflammation is related to a long list of health ailments (6, 8).

Astaxanthin supports your immune health by acting as an antioxidant which can decrease oxidative stress (3, 4).

It has also been shown that because of its anti-inflammatory properties, astaxanthin has been used in clinical trials to treat metabolic syndrome, atherosclerosis, cognitive impairment, muscle damage, visual fatigue, and dermatological diseases with hopeful results (3).

Maintains immune system health

Astaxanthin maintains immune system health by helping mitigate tissue damage that may occur due to excessive immune system response (8).

Astaxanthin modulates the production of various immune system cells, without causing significant cytotoxic effects (7). It can also support healthy immune system function by stimulating the production of immune cells. Because of this astaxanthin may help in treating or preventing immune diseases.

Other vitamins to boost immunity

Besides astaxanthin, here are other vitamins that can support immune health which you can include as part of your everyday diet:

Vitamin C

Vitamin C helps maintain healthy immune system function (9). This vitamin is found in citrus fruits, spinach, brussel sprouts, and papaya.

Vitamin D

Vitamin D helps support the immune system by maintaining absorption of dietary nutrient intake (9). You can get this from the sun, as well as eating salmon, tuna, and sardines.


Iron is an antioxidant that reduces free radicals formed in the body, and helps the immune system to fight illness. Its main function in the body is to help carry oxygen to your cells (9). Iron can come from chicken, sardines, mussels, and broccoli.

*Iron should only be taken if prescribed by your doctor.

When paired with a healthy diet and regular exercise, astaxanthin can help support immune health.
