Three concerns. Three complete formulas.



Blood sugar · 11 ingredients
For people who eat sensibly and want a supplement that pulls its weight.
300 mg berberine phytosome and 200 mg Gynura divaricata lead eleven ingredients, with chromium, which contributes to the maintenance of normal blood glucose levels.
Made for you if
- You want to keep your blood sugar in the normal range
- You've tried plain berberine and want a fuller formula
- You'd rather take one bottle than six
Energy & healthy ageing · 9 ingredients
For people who used to have more in the tank at 4pm.
Magnesium contributes to the reduction of tiredness and fatigue. Ca-AKG+ pairs magnesium glycinate with 1,000 mg Ca-AKG, 120 mg ubiquinol CoQ10, spermidine, PQQ, vitamin D3 and K2.
Made for you if
- You're flagging by mid-afternoon
- You take several supplements and can't tell what's doing what
- You want D3 and K2 without buying them separately
- You want to enjoy healthy, active ageing
Joints & mobility · 10 ingredients
For people who aren't ready to give up the long walk.
40 mg UC-II collagen, the amount used in the published research, with PEA, eggshell membrane, Boswellia and astaxanthin. Ten ingredients, two capsules.
Made for you if
- You walk, run, garden or lift, and want to keep at it
- You've tried glucosamine and chondroitin and want a broader joint formula
- You'd rather take one bottle than four
Why the shelf keeps growing
It isn't you. It's the half-solutions.
Most supplements hold one ingredient. So you buy a second, then a third, and end up with a shelf of bottles, a dozen capsules a day and no idea which of them is doing anything.
Each Brittica formula puts the whole set in one bottle, at doses you can read before you buy.
Side by side
The shelf, or the bottle.

| Doses on the label | Often hidden in blends | Every one |
| Research | Marketing claims | Linked studies, limits stated |
| Cost a day | £2 to £3 | From 82p |

Questions
Straight answers.
Which formula is right for me?
Start with what matters most to you. Blood sugar: GlycoShift, our berberine phytosome formula, whose chromium contributes to the maintenance of normal blood glucose levels. Energy: Ca-AKG+, whose magnesium contributes to the reduction of tiredness and fatigue. Staying active: Supple X, with 40 mg UC-II, PEA and Boswellia.
How long does the offer price last?
Every formula is £29.50 a bottle, or £24.50 a bottle on the 90-day plan (£73.50 for three). The offer price runs until 31 December 2026, then prices go back to £39 to £49 a bottle.
Why a 90-day plan?
One bottle lasts 30 days, which is a start rather than a fair test. Three bottles give the routine time to settle in, cost 82p a day and save £15 against buying them one at a time. At day 90 you reorder or pause.
Can I take two formulas together?
Yes, each is two capsules a day. GlycoShift and Ca-AKG+ both contain CoQ10 and PQQ, so check the combined amounts on the labels.
What if it isn't for me?
You can return unopened bottles within 14 days. On the 90-day plan you can also pause at day 90 instead of reordering.
I take medication. Can I use these?
Speak to your GP or pharmacist before starting any supplement if you take medication, are pregnant or breastfeeding. GlycoShift contains berberine, which can interact with some medicines.
Where do you deliver?
Free to UK mainland. Northern Ireland and Ireland £4.95, EU £9.95, US £15.95.
