Which antioxidant supplements are expected to see the highest growth, according to surveys?

The COVID-19 pandemic has exponentially increased the sales of supplements, especially immune-support products. Antioxidant ingredients can also be included in this category. As a manufacturer of nutritional supplements, we have also seen increased interest from private label owners in antioxidant supplements over a longer period. Let’s take a look at them.

1. Chlorella

This freshwater green alga is already well-known to end customers, as it is often referred to as a superfood. It contains fibre, omega-3 fatty acids, and a wide range of vitamins, minerals and other antioxidants. 

Health benefits of chlorella

Research suggests that it may contribute to the prevention of dementia, increase aerobic endurance or help remove heavy metals from the body. It may also have a beneficial effect on the immune system, as confirmed by a 2012 clinical study. It might be interesting for people who prefer a vegan diet, as chlorella contains vitamin B12, iron and a significant amount of protein

Chlorella market development

The chlorella market is expected to reach a value of $412.3 million by 2028, registering a CAGR (compound annual growth rate) of 6.3% from 2021 to 2028. Factors such as increased consumer interest in protein-rich diets, healthy lifestyle trends and a growing number of vegetarians contribute to the growth.


2. Spirulina

It contains vitamins, iron, magnesium and, like chlorella, is a source of protein. Their quality is comparable to that of eggs, as spirulina provides all essential amino acids

Health benefits of spirulina

Research suggests efficacy in preventing cardiovascular disease, regulating blood sugar or treating allergic rhinitis. Spirulina contains the substance phycocyanin, for which research shows antioxidant, anti-inflammatory and brain-protective properties. A 2016 meta-analysis suggests that spirulina can significantly reduce total cholesterol.

The spirulina dietary supplements market is expected to register a CAGR of 5.80% between 2021 and 2028. Factors contributing to the growth include rising disposable income and an increase in the vegetarian population.


3. Ashwagandha

The ashwagandha plant has a long history of use in traditional Ayurvedic medicine, where it is used as an adaptogen for many stress-related conditions. This substance is believed to help the body resist physical and mental stress.

Health benefits of ashwagandha

Scientific research into the effects on stress has revealed promising results. In a 2019 human study, researchers found that a daily dose of 240 mg of ashwagandha significantly reduced stress levels, including levels of the stress hormone cortisol, compared to a placebo. Other research suggests a positive effect on memory, blood sugar levels, or reducing inflammation in the body.

Ashwagandha market development

The global ashwagandha market is expected to grow at a CAGR of 11.4% from 2022 to 2029. A 2021 study shows that, according to Google Trends, global searches for ashwagandha have doubled over the past two years. The market for ashwagandha supplements saw a 65% year-over-year increase on Amazon.


4. Maca 

Maca is a cruciferous vegetable from the Peruvian Andes, where it has been cultivated for more than 2,000 years. The root of this plant contains, among other things, vitamins, minerals, amino acids and alkaloids. In recent years, however, there has been an increased global demand for products from maca root, also thanks to the claims that it can boost libido and fertility. 

Health benefits of maca root

Possible health benefits of maca root include improving energy levels or mood, but the most well-known is the potential to increase libido. A 2010 review of studies found that taking maca has the potential to improve sexual desire. However, the authors cautioned that more research is needed. A 2015 study revealed that maca root may help reduce sexual dysfunction in postmenopausal women who were taking antidepressants.

Maca root market development

The global maca powder market is expected to register a CAGR of 9.86% in the period to 2028. Increasing awareness among end-consumers about the medicinal benefits of maca powder contributes to the growth of demand for products containing it.

The mushroom is well-known in Asian countries, where it is used for both consumption and medicinal purposes. It contains bioactive substances that have a positive effect on the human body, especially the brain, heart and digestion

Health benefits of Lion’s mane mushroom

Animal studies suggest that Lion’s mane mushroom may improve cognitive function. For example, a 2016 study revealed the potential to treat or prevent diseases that cause cognitive decline, such as Parkinson’s or Alzheimer’s disease. Other potential health benefits include, e.g., relief of mild symptoms of anxiety and depression or suppressing the development of stomach ulcers.
