Description
PEScience Exotic Reds & Blues
A reds and blues powder — concentrated fruit and berry extracts, rather than the vegetable-based greens formulas that dominate this category.
Reds versus greens: a genuine difference
These are not interchangeable, and the distinction is worth understanding before you buy either.
| Greens powders | Spinach, kale, broccoli, spirulina, grasses | Chlorophyll, sulforaphane, vitamin K |
| Reds and blues | Berries, cherries, beets, grapes, pomegranate | Anthocyanins, polyphenols, nitrates |
The pigments are the point. The compounds giving fruit its deep red, blue and purple colour — anthocyanins — are the polyphenols the research focuses on. They are a genuinely different class of compound from what greens supply, which is why the two are complementary rather than duplicative.
What the research on this area looks at:
- Exercise recovery. Tart cherry in particular has research behind reduced muscle soreness and improved recovery markers after hard training
- Antioxidant capacity, since polyphenols are the compounds behind those measurements
- Blood flow, where beet and pomegranate contribute through nitrate and polyphenol pathways
- Cognitive markers, where blueberry anthocyanins have some interesting preliminary work
⚠ The mouthwash point, if it contains beet
Reds formulas frequently include beet, and this matters if you take it before training.
Nitrate has to be converted to nitrite before it becomes nitric oxide — and that first step is performed by bacteria on your tongue, not by your own cells.
Antibacterial mouthwash kills those bacteria and substantially blunts the effect. Skip it on training days if the pump or blood flow side is why you are taking this.
The honest position
Same as we take on greens, because it is the same category.
A reds powder is not a substitute for eating fruit and vegetables. Real produce brings fibre in meaningful quantities, volume, water content and the full whole-food matrix that drying and processing strip out.
What it is genuinely good for is insurance — if your fruit and vegetable intake is honestly poor, this supplies polyphenols you would otherwise miss entirely. Something beats nothing.
And one genuine advantage over greens: reds powders generally taste considerably better. That sounds trivial, but the greens powder abandoned in a cupboard does nothing at all — palatability is a large part of whether any of this works.
⚠ One caveat worth knowing for athletes
Worth flagging, since it applies to concentrated antioxidants generally.
Exercise-induced oxidative stress is part of the signal that drives adaptation. Some research suggests high-dose antioxidant supplementation taken around training may blunt some of those adaptations.
The evidence is mixed and the effect is not established at typical supplemental doses — but the cautious approach is to take concentrated antioxidants away from your training window rather than immediately before or after. Same reasoning we apply on our NAC page.
How to read the label
- ⚠ Check for a proprietary blend. A label listing twenty fruits under one 2,000mg total averages 100mg each, which is a dusting
- Where the ingredient list starts — ingredients are ordered by weight
- Standardised extracts beat raw fruit powders, since the polyphenol content is what matters rather than the total weight
- Sugar content, since concentrated fruit carries some
Specs
| Type | Fruit and berry polyphenol powder |
| Distinct from | Greens powders — different compound class |
| Stimulants | None |
How to take it
- Once daily, mixed into water.
- Away from your training window if you are being cautious about the antioxidant point.
- Alongside fruit and vegetables, not instead of them.
- Skip antibacterial mouthwash on training days if it contains beet.
- Alongside a greens powder rather than instead of one, if you want both compound classes.
Who this is for
- Anyone whose fruit intake is genuinely poor
- People who have tried greens powders and could not stomach the taste
- Anyone interested in polyphenols specifically rather than general micronutrients
- People training hard, where recovery is the priority
- Anyone already taking a greens powder who wants the other half
Who this is not for
Anyone eating plenty of fruit and vegetables already. The incremental benefit is small, and we will say so.
Anyone treating it as a replacement for produce. Fibre, volume and satiety come from real food.
Anyone expecting it to replace a greens powder. Different compounds — they are complementary.
Anyone taking it immediately around training, if you are cautious about antioxidants and adaptation.
Not for anyone under 18, pregnant or nursing without medical advice.
Stack it with: a greens powder for the other compound class, and actual fruit and vegetables before either.
Frequently asked questions
How is a reds powder different from greens?
Different compounds. Reds supply anthocyanins and polyphenols from berries and fruit; greens supply chlorophyll, sulforaphane and vitamin K from vegetables. Complementary rather than duplicative.
What are anthocyanins?
The pigments giving fruit its deep red, blue and purple colour — and the polyphenols most of the research focuses on.
Can it replace fruit and vegetables?
No. Real produce brings fibre, volume and the full whole-food matrix. This is insurance for when intake is genuinely poor.
Should I take it around training?
The cautious approach is away from your training window, since high-dose antioxidants may blunt some exercise adaptations. The evidence is mixed at typical supplemental doses.
Does it help recovery?
Tart cherry in particular has research behind reduced soreness and improved recovery markers after hard training.
Why does mouthwash matter?
If it contains beet, bacteria on your tongue perform the first step converting nitrate to nitrite. Antibacterial mouthwash kills them.
Does it taste better than greens?
Generally, considerably — which matters, because an abandoned tub does nothing at all.
Do I need both reds and greens?
If your produce intake is poor, they cover different compound classes. If you eat well, neither adds much.
