Antioxidant Seed Mix
Leafea Antioxidant Seed Mix — six ingredients, one jar, 315g.
"Eat the rainbow" isn't just a saying — colour in food is often a direct sign of antioxidant content. Deep reds, purples and oranges in berries and seeds usually point to the plant pigments and compounds doing the antioxidant work. This guide covers what antioxidants actually do, which foods are richest in them, and how Leafea Antioxidant Seed Mix — pumpkin kernels, goji berries, cranberries, basil seeds, flax seeds and sunflower kernels — makes it easy to add more of them to your day.
What are antioxidants, really?
Antioxidants are compounds that help protect your cells from free radicals — unstable molecules produced naturally by the body, and increased by things like pollution, UV exposure and processed food. Left unchecked, free radicals contribute to oxidative stress, which research links to ageing and a range of chronic health issues. Antioxidants work by neutralising free radicals before they can do that damage.
The body makes some antioxidants on its own, but a large share comes from food — which is why "antioxidant foods" and "foods high in antioxidants" are such consistently popular search terms. Fruits, vegetables, nuts, seeds, herbs and spices are the main dietary sources, and the most antioxidant-dense foods tend to be the most vividly coloured.
Why colour is a clue
Deep red, purple and orange pigments in plant foods usually come from flavonoids and carotenoids — two major antioxidant groups. Goji berries get their bright red-orange colour from carotenoids including zeaxanthin and beta-carotene. Cranberries owe their tartness and colour to polyphenols. It's not a coincidence that the most talked-about antioxidant foods — berries, in particular — are also some of the most colourful items in the produce aisle.
Antioxidant-rich foods beyond fruit: seeds and nuts
Berries get most of the attention, but nuts and seeds are a genuine source of antioxidants too — particularly vitamin E, a fat-soluble antioxidant vitamin. Sunflower seeds are regularly singled out as one of the more concentrated plant sources of vitamin E, and basil and flax seeds contribute their own antioxidant and anti-inflammatory plant compounds. Combining antioxidant-rich berries with antioxidant-rich seeds in one mix covers more ground than either on its own.
What's in the jar
Six ingredients, nothing hidden. Pumpkin kernels make up the largest share at 25%, and the other five are blended evenly at 15% each.
Net weight 315g. Gram amounts are approximate, based on the percentages on the jar. Bars are scaled to the largest ingredient.
Why each ingredient is in the mix
Pumpkin kernels (25%)
The crunchy base of the mix. Pumpkin kernels contribute plant protein, magnesium and zinc alongside their satisfying, nutty bite.
Goji berries (15%)
One of the most recognisable antioxidant foods. Goji berries are known for carotenoids like zeaxanthin and beta-carotene, which give them their deep red-orange colour.
Cranberries (15%)
A tart, fruity lift that balances the richer seeds. Cranberries are a well-known source of polyphenols, a group of plant compounds with antioxidant activity.
Basil seeds (15%)
Small seeds with a distinctive texture. Basil seeds are a source of dietary fibre and plant-based omega-3 (ALA), alongside their own antioxidant plant compounds.
Flax seeds (15%)
Another plant source of omega-3 (ALA) and fibre, with a mild, earthy flavour that blends easily into almost anything.
Sunflower kernels (15%)
Mild, slightly sweet and naturally rich in vitamin E — an antioxidant vitamin repeatedly highlighted by nutrition researchers as one of sunflower seeds' standout qualities.
Easy ways to add antioxidant foods to your day
You don't need a dramatic diet change to eat more antioxidant-rich foods — small, consistent additions add up. A spoonful of Antioxidant Seed Mix works in:
- Breakfast: over yoghurt, porridge or cereal
- Smoothie bowls: scattered on top for colour, crunch and antioxidants in one go
- Salads: tossed through for crunch and a little natural sweetness
- Baking: stirred into homemade granola, muffins or bread
- Snacking: by the spoonful, straight from the jar
A simple habit, not a strict diet
The research is consistent on one point: a varied diet rich in plant-based foods is the most reliable way to get a broad spectrum of antioxidants, rather than relying on any single "superfood." An antioxidant seed mix isn't a replacement for vegetables and fruit — it's an easy, no-prep way to add another layer of colourful, antioxidant-rich ingredients to meals you're already eating.

What are antioxidants and why do they matter?
Antioxidants are compounds that help protect cells from free radicals, unstable molecules linked to oxidative stress and ageing. The body makes some on its own, but a large share comes from food, particularly colourful fruits, vegetables, nuts and seeds.
What foods are highest in antioxidants?
Berries such as goji berries and cranberries are commonly cited among the highest antioxidant foods, alongside nuts and seeds like sunflower kernels, which are a notable source of vitamin E.
Why are goji berries considered a superfood?
Goji berries contain carotenoids such as zeaxanthin and beta-carotene, along with unique polysaccharides, giving them a concentrated antioxidant profile that's well documented in nutrition research.
Do seeds have antioxidants, or just berries?
Seeds contribute antioxidants too, particularly vitamin E. Sunflower kernels are a frequently cited plant source of vitamin E, and seeds like flax and basil add their own antioxidant and anti-inflammatory plant compounds.
Can I eat Antioxidant Seed Mix every day?
Yes — it's designed as an everyday addition to meals such as breakfast, smoothie bowls, salads and baking, rather than a one-off product.
