ANTIOXIDANT SUPERFRUITS
Nature’s most colourful chemistry.
Açaí, goji, blackcurrant, red-grape skin. Some of the most celebrated superfoods on earth — prized for the deep purples and reds that signal an exceptional concentration of plant antioxidants.

ULTIMATE brings açaí, goji and grape skin. MUSCLE-AID pairs goji with blackcurrant — the Northern Hemisphere’s powerhouse berry and a favourite of sports-recovery researchers. Each one adds its own family of polyphenols: anthocyanins, stilbenes, carotenoids and polysaccharides. ULTIMATE’s green tea and grape seed have their own page.

Açaí — the Amazon’s purple powerhouse
Açaí is the deep-purple palm berry of the Amazon rainforest, and one of the world’s most famous superfoods. Its reputation is built on remarkable antioxidant chemistry.
When researchers measured freeze-dried açaí pulp and skin across a series of antioxidant assays, they found exceptional activity against the superoxide radical — and, against the peroxyl radical, the highest ORAC value of any food reported at the time.
THE HIGHEST PEROXYL-RADICAL ORAC OF ANY FOOD REPORTED TO DATE

Açaí has also been studied in people with everyday aches. In a 12-week clinical pilot, 14 adults with pain-limited range of motion drank an açaí-pulp-rich fruit and berry juice daily. Researchers reported reduced pain and improved range of motion over the study.

Goji — a superfood with centuries of tradition
Goji berries — Lycium barbarum — have been treasured in traditional Asian herbal practice for centuries and are now one of the world’s best-known superfoods. Their signature compounds are the Lycium barbarum polysaccharides, alongside carotenoids such as zeaxanthin and a rich mix of polyphenols.
In a randomised, double-blind, placebo-controlled study, healthy adults drinking standardised goji juice for 14 days reported significant increases in energy level, athletic performance, sleep quality, ability to focus, calmness and feelings of overall wellbeing.
More energy. Better athletic performance. Greater wellbeing.

Goji’s polysaccharides have also been studied directly in skin biology, where they protected skin cells against UVB-induced photoageing and oxidative damage.

Goji’s polysaccharides reach joint biology too. A systematic review highlighted Lycium barbarum polysaccharides’ anti-ageing, antioxidant and anti-inflammatory activities as a promising fit for ageing joints, and in a 2025 experimental osteoarthritis model, LBP slowed osteoarthritis progression by protecting chondrocytes from ferroptotic cell death.

Goji is in both ULTIMATE and MUSCLE-AID.
Blackcurrant — the recovery berry
Blackcurrants are one of the richest natural sources of anthocyanins — the deep-purple pigments behind their intense colour — and New Zealand blackcurrant has become a favourite of sports scientists.
In a double-blind, randomised, placebo-controlled trial, blackcurrant extract taken before and after strenuous resistance exercise improved recovery from exercise-induced muscle damage. Further research has found blackcurrant extract enhanced muscle oxygenation during repeated forearm contractions in advanced and elite rock climbers.
Faster recovery from exercise-induced muscle damage.

A separate randomised placebo-controlled study found blackcurrant nectar, taken for eight days around a bout of high-intensity eccentric knee extensions, reduced creatine kinase — a blood marker of muscle damage — and the inflammatory cytokine IL-6, while boosting blood antioxidant capacity.

Blackcurrant is in MUSCLE-AID.
Grape skin — the colour of red grapes
The skin of the red grape is where the vine concentrates its most famous protective chemistry: the deep-red anthocyanins behind its colour and the stilbenes led by trans-resveratrol. In human articular chondrocytes, resveratrol suppressed IL-1β-driven inflammatory signalling and the cartilage-degrading enzymes MMP-3 and MMP-9 — and in a randomised, double-blind, placebo-controlled trial of 110 adults with knee osteoarthritis, resveratrol supplementation significantly reduced knee pain.

Grape skin is in ULTIMATE.
A spectrum of colour, a spectrum of chemistry
Each superfruit brings a different family of polyphenols. Anthocyanins from açaí, grape skin and blackcurrant. Stilbenes from grape skin. Polysaccharides and carotenoids from goji. Together they create a broad, complementary antioxidant spectrum — and they partner beautifully with the pomegranate, mangosteen and liposomal vitamins C and E elsewhere in the formulas, and with ULTIMATE’s green tea and grape seed.
