Antioxidants and Natural Extracts

What are antioxidants and natural extracts, and why will your body appreciate them?

To understand why antioxidants are useful, you only need one term: oxidative stress. During normal cell function, but also due to stress, pollution, smoking, or intense training, free radicals are generated in the body. Think of them as sparks flying around that damage cellular structures, proteins, and DNA. Antioxidants are substances that extinguish these sparks before they can cause damage.

The body has its own antioxidant defense, but it can also be supported from the outside. That's where natural extracts come in—concentrates of active ingredients obtained from plants, algae, and mushrooms. They differ from standard vitamins in that they usually contain a full spectrum of phytonutrients: polyphenols, carotenoids, flavonoids, or specific plant molecules that work together.

It is important to distinguish between two levels:

• Authorised health claims. Vitamin C, vitamin E, riboflavin, and minerals like selenium, zinc, copper, and manganese are proven to contribute to the protection of cells from oxidative stress. This is one of the few claims in this area approved by the European Food Safety Authority (EFSA, Regulation No. 432/2012).
• Traditional use and current research. For most natural extracts and adaptogens, we rely on centuries of experience and modern clinical studies. These substances do not have official EFSA health claims, but research into their effects is vibrant and, for some, very compelling.

Who are antioxidants and natural extracts for?

The beauty of this category is that almost everyone can find something for themselves. Natural extracts are not just for "herbalists". They are used by:

• Active athletes, for whom intense strain increases oxidative stress and recovery needs.
• People under chronic stress, looking for a natural way to calm their busy mind, typically through adaptogens.
• People who care about health and longevity.
• Supplement beginners, who want a simple and understandable first step, often through superfoods like supergreens.
• Experienced users, who build sophisticated protocols from specific, standardised extracts.

Adaptogens: Natural helpers against stress and fatigue

Adaptogens are plants that help the body better "adapt" to stress, whether physical or mental. They act gently and comprehensively, often via the axis that manages our stress response. They are among the most sought-after natural extracts of all.

Ashwagandha

Ashwagandha is the star of this entire category, and scientific evidence backs it up. A systematic review and meta-analysis of randomised trials confirmed that standardised ashwagandha extracts significantly reduce perceived stress, anxiety, and cortisol levels, the primary stress hormone (Arumugam et al., 2024).

In one of the most cited studies, morning cortisol levels dropped significantly in stressed individuals compared to a placebo (Lopresti et al., 2019). Newer research shows that a measurable effect on stress management occurs with a dose of just 125 mg per day (Pandit et al., 2024).

What to look for when choosing:

• Prefer standardised and patented extracts like KSM-66, where you know exactly how many active withanolides you are getting.
• Common dosage ranges between 300 and 600 mg of extract per day.
• Ashwagandha is available in capsules, powder, and convenient gummies.

Ginseng (Panax ginseng)

Ginseng is a pillar of traditional Eastern medicine and is popular in Europe as natural support for vitality, mental freshness, and physical performance. It is often combined with other adaptogens, which is why you will also find it in complex blends along with ashwagandha and green tea.

For supplementation, go for Korean ginseng (also referred to as true or red ginseng), ideally with a standardised content of active ginsenosides. Distinguish this from Siberian ginseng, which is botanically different.

Maca

Maca root grows high in the Peruvian Andes and is traditionally used to support energy, mood, and libido. Clinical studies suggest that maca may have a positive effect on mood, energy, and perceived well-being (Gonzales-Arimborgo et al., 2016), and systematic reviews point to a potential influence on sexual function, although authors call for further research (Shin et al., 2010).

It is available as a powder or in capsules, typically in a dose of 1.5 to 3 g per day. An interesting aspect is the colour variation of the root (yellow, red, black), which can influence the active substance profile.

Rhodiola rosea

Rhodiola is an adaptogen particularly popular during moments of mental fatigue and exhaustion. It is often a component of pre-workout and "anti-stress" formulas, and you will appreciate it as a supplement to ashwagandha if you are dealing with short-term periods of increased load rather than long-term stress.

Seaweed and Superfoods: Nutrients in concentrated form

Superfoods are foods with an exceptionally high concentration of nutrients and antioxidants in a small volume. They often come as a superfood drink mix, known as super greens or simply greens—a green powdered drink that packs what you would otherwise look for in a whole bowl of vegetables into one glass. These green superfoods combine algae, young grasses, fruit and vegetable extracts, and often fibre and probiotics.

What is Spirulina?

Spirulina is a blue-green algae packed with protein, vitamins, and the pigment phycocyanin, which is credited with antioxidant action. Meta-analyses of randomised trials show that spirulina increases the overall antioxidant capacity of the body and reduces markers of oxidative stress and inflammation (Mousavi et al., 2025). A bonus is its favourable influence on lipid profiles. It is used in tablets and powder, usually in doses of 1 to 8 g per day.

What is Chlorella?

Chlorella is a freshwater algae that people have grown to love as a supplement for "detoxification" and nutrient replenishment. It is often combined with spirulina because both algae complement each other in their profiles. If you are looking for a simple entry into the world of superfoods, the spirulina and chlorella duo is a proven choice.

Green Barley and Wheatgrass

Green barley and wheatgrass juice are classic green superfoods rich in chlorophyll, enzymes, and antioxidants. They are perfect for a morning smoothie and form the basis of many complex superfood drink mixes that, besides algae, also contain fruit and vegetable extracts, fibre, and probiotics.

Tip: The complete range of super greens and green superfood powders can be found in the Superfoods subcategory.

Plant extracts and carotenoids

While adaptogens work on overall resilience and superfoods replenish nutrients, this group of natural extracts targets specific areas.

Ginkgo biloba

Ginkgo biloba is among the oldest and most researched plant extracts. It is traditionally associated with supporting brain circulation, memory, and concentration. Review papers summarise that standardised leaf extract from ginkgo has antioxidant properties and supports cerebral circulation (Barbalho et al., 2022), with the best-researched dosage being around 120 to 240 mg of standardised extract per day (Tan et al., 2015).

Always reach for a standardised extract, not an unspecified "leaf powder".

Astaxanthin

If you are looking for one of the strongest antioxidants in this category, astaxanthin is a hot candidate. This red carotenoid from seaweeds has, according to a review of clinical studies, an exceptionally high ability to scavenge free radicals, orders of magnitude higher than, for example, vitamin E (Donoso et al., 2021).

Human studies confirm that astaxanthin increases total antioxidant capacity and reduces markers of oxidative damage (Choi et al., 2011), and a systematic review describes its benefits for the skin, particularly hydration and elasticity, and hair (Ng et al., 2021). Common dosage is 4 to 12 mg per day.

Tip: Combine beauty antioxidants from within with the selection in the Skin, complexion, and hair category.

Resveratrol

Resveratrol is a polyphenol that occurs naturally in grape skins and red wine. It is the focus of research aimed at healthy ageing and protecting cells from oxidative stress. On the market, you will find biologically active trans-resveratrol in capsules.

Curcumin

Curcumin is a yellow pigment from turmeric, valued for its antioxidant and anti-inflammatory properties. It has one weakness: it is poorly absorbed on its own. Therefore, reach for formulas of curcumin with piperine (an extract from black pepper), which significantly increases its absorption.

Saw Palmetto and other specialised extracts

Saw palmetto is an extract from palm fruit, sought after particularly by men in relation to prostate and urinary tract health. You will find it in our range both individually and in combination complexes. Alongside it, you will encounter other targeted plant extracts in this category:

• milk thistle (traditionally associated with liver support – you can also find it in products like Liv.52),
• echinacea,
• green tea,
• ginkgo, or
• grape seed extract.

Cellular and thiol antioxidants: NAC and Alpha-lipoic acid

A special group consists of substances that the body uses directly in its own antioxidant defence:

• NAC (N-acetylcysteine) is a precursor to glutathione, often referred to as the body's master antioxidant.
• ALA (alpha-lipoic acid) is a universal antioxidant soluble in both water and fat, allowing it to act across different environments in the cell.

Both substances are appreciated by advanced users who want to specifically support cellular antioxidant capacity.

How to choose the best antioxidants and natural extracts?

Before putting a product in your basket, go through this simple checklist. It will help you separate quality from empty marketing.

• Start with the goal, not the ingredient. Are you dealing with stress? Ashwagandha can be a good choice. Do you want to replenish nutrients? Reach for superfoods. Are you looking for cell protection and skin health? Opt for astaxanthin or resveratrol.
• Watch for standardisation. For extracts, the content of the active ingredient is key (e.g., withanolides in ashwagandha, ginsenosides in ginseng). Patented extracts like KSM-66 give you peace of mind regarding the formulation.
• Consider the form and bioavailability. Some substances are poorly absorbed on their own. Therefore, look for curcumin with piperine; fat-soluble carotenoids like astaxanthin are best absorbed with a meal containing fat.
• Read the ingredients. Less is sometimes more. A short list with a high dose of active ingredient is often better than a long list of plants in negligible amounts.
• Choose vegan products or products without specific allergens if you need to. A large portion of natural extracts are suitable for vegans and vegetarians; you can also find them gluten-free and lactose-free.

Antioxidants and natural extracts: what not to forget

Antioxidants and natural extracts are one of the most diverse ways to support your body and mind in a natural form. Whether you are seeking calm in the middle of a demanding period with ashwagandha, boosting energy with maca, strengthening antioxidant defence with spirulina and astaxanthin, or just want a simple daily dose of greens from superfoods, the key is always the same: choose based on your goal and quality.

And we must mention: Dietary supplements are not a substitute for a varied diet or medication. If you are taking medication, are pregnant, or breastfeeding, discuss the introduction of natural extracts with your doctor.
