Why Choose Our Antioxidants?

Want to boost your health and feel your best every day? VitaBright’s antioxidant supplements are packed with pure, high-quality ingredients, giving your body the ultimate defence against oxidative stress—no fillers, just powerful results!

What is Oxidative Stress?

A lack of antioxidants leads to a huge array of health problems and chronic diseases. Why is this?

We need to breathe in oxygen all the time, because our bodies use it to power all the chemical reactions that make up our metabolism. At the centre of these processes are Reactive Oxygen Species (ROS), also sometimes called Free Radicals. In the right amounts, these power-pack molecules drive our body processes. But when too many of them get out of control, they cause damage called oxidative stress to our body - the same process as metal rusting, fruit going brown and oil turning rancid.

To stop this happening, our body makes antioxidant molecules like glutathione and Superoxide Dismutase to keep these ROS under control.

Why choose VitaBright Antioxidant Supplements?

Don’t waste your money on low-quality antioxidants. They may contain ineffective doses, synthetic fillers, and poor absorption, giving you little to no health benefits.

Our Bioavailable Ingredients work faster

Our antioxidant supplements contain highly absorbable forms of activated “body-ready” vitamins, and absorption boosters like black pepper.

We’re Junk Free

Our clean formulations avoid unnecessary flavourings, fillers, artificial additives, synthetic ingredients and GMO crops. We keep our supplements allergen-free and vegan wherever possible.

We use Standardised Extracts

Our herbal antioxidants like Turmeric, Ashwagandha, and Cranberry Extract are standardised to guarantee high levels of active compounds like curcumin or with anolides.

Everything is Third-Party Tested

We provide independent lab testing to verify purity, potency, and safety.

Sustainable Sourcing

Our ethically sourced, certified organic ingredients ensure higher quality and better environmental impact.

The Best Antioxidant Supplements

NAC (N Acetyl Cysteine) - Antioxidant nutrient

N-acetyl cysteine is a vital and powerful antioxidant supplement that directly boosts glutathione, the human body's "master antioxidant" molecule. NAC feeds into our natural antioxidant enzyme system to create this powerful molecule which scavenges illness-causing free radicals throughout the body. 

Quercetin - Antioxidant botanical supplement

Quercetin is one of the most effective plant-based antioxidants called flavonoids, which neutralise harmful free radicals (oxygen molecules) in the body. It's also been studied for its anti-inflammatory effects and potential benefits for heart health, immune function, and overall well-being.

Zinc - Antioxidant nutrient

Zinc plays a core role in antioxidant activity as well as immune function, helping to protect cells from oxidative stress and supporting cellular repair.

Turmeric - Antioxidant botanical supplement

Curcumin, the active compound in Turmeric, is a powerful botanical antioxidant with anti-inflammatory properties. It helps neutralise free radicals and supports joint, brain, and cardiovascular health.

Antioxidant Supplements & Vitamins FAQs

What do antioxidant supplements do? +

Antioxidant supplements help protect the body from oxidative stress by neutralising free radicals, which can cause cell damage, premature aging, and chronic diseases. They may help the body build essential antioxidant substances like glutathione or superoxide dismutase, or contain ready-made antioxidant substances that can help.

What is the best antioxidant supplement? +

There isn't a single best antioxidant supplement—different antioxidants work in various ways to support the body, and it’s vital to have a variety of them. NAC (N-Acetyl Cysteine) is a direct precursor to glutathione, one of the human body’s most important antioxidant substances.

Botanicals like quercetin and turmeric (curcumin) have ready-made molecules that also help neutralise harmful free radicals, reducing oxidative stress and inflammation in the body.

Is it safe to take antioxidants every day? +

Yes, taking antioxidant supplements daily is safe, as long as they are taken at the correct doses indicated on the label. It's best to take a balanced approach, focusing on whole foods alongside high-quality antioxidant supplements to avoid over-supplementation.

Is there a downside to antioxidants? +

While antioxidants provide many benefits, over-supplementation above the recommended dose can sometimes be harmful—especially with fat-soluble vitamins like A and E. Some antioxidants may also reduce the effectiveness of chemotherapy or radiation therapy, so they may not be ideal for everyone.

Is vitamin B12 an antioxidant? +

Vitamin B12 is not a direct antioxidant, but it does play a role in reducing oxidative stress by supporting energy metabolism and nerve health. It helps the body produce red blood cells and maintain brain function, indirectly benefiting antioxidant defence systems. While B12 is not considered one of the best antioxidant supplements, it works alongside antioxidants like glutathione and vitamin C to support cellular health.

What happens when you start taking antioxidants? +

When you begin taking antioxidant supplements, you may notice increased energy levels, improved skin health, enhanced immune function, and better cognitive clarity. Over time, antioxidants help reduce inflammation, slow aging, and support organ function. The best antioxidant supplements can also aid in workout recovery and protect against environmental stressors like smoking and pollution.

Why take antioxidants at night? +

Taking antioxidant supplements at night allows the body to repair itself while you sleep. Antioxidants like NAC, quercetin, and Omega-3s support cellular detoxification, immune function, and tissue repair. Additionally, some of the best antioxidant supplements, like turmeric and resveratrol, have calming and anti-inflammatory effects, which can enhance restorative sleep.
