Not Just Ca-AKG
One Capsule.
Seven Ingredients.
Most AKG supplements give you one ingredient and call it a day. We built something bigger: 1,000mg of 99% pure Ca-AKG, plus six co-factors, each at a clearly stated dose — no proprietary blends, nothing hidden. Calcium, vitamin D, vitamin K and magnesium contribute to the maintenance of normal bones. Magnesium contributes to normal energy-yielding metabolism and the reduction of tiredness and fatigue. Vitamin D contributes to the normal function of the immune system. And around that core: PQQ, CoQ10, hydroxytyrosol, spermidine and French maritime pine bark — the nutrients at the centre of today's most-watched ageing research.
No proprietary blends. Every dose listed. All seven ingredients justified.
Full Ingredient Breakdown
Calcium Alpha-Ketoglutarate (Ca-AKG)
Here's what most supplement brands won't tell you: your body makes AKG naturally — and by mid-life, those levels are in decline. It's a compound your cells use in the Krebs cycle, the engine that turns food into energy. We put 1,000mg of it back, at 99% purity, in every daily serving. It's the foundation everything else builds on.
Vitamin D3 + K2 (MK-7)
The pairing that makes the calcium count. Vitamin D contributes to normal absorption of calcium, and both vitamin D and vitamin K contribute to the maintenance of normal bones. We use K2 in its long-lasting MK-7 form — the detail cheaper formulas skip.
PQQ + CoQ10 (Ubiquinol)
Two of the most-watched compounds in ageing research. CoQ10 lives inside your mitochondria — the structures where your cells produce energy — and we use its active ubiquinol form. PQQ is the nutrient researchers keep writing papers about. Most brands make you buy them separately. We built both in.
Magnesium Glycinate
The mineral behind over 300 processes in your body — and one most people in the UK don't get enough of. Magnesium contributes to normal energy-yielding metabolism and the reduction of tiredness and fatigue. We use the glycinate form: gentle on the stomach, well absorbed, no shortcuts.
Hydroxytyrosol (Olive Leaf)
The compound behind the Mediterranean diet's reputation. Hydroxytyrosol is the prized polyphenol in olive oil — we concentrate it from the olive leaf, so you get 50mg without drinking a bottle of oil a day.
Spermidine (Triticum aestivum)
The compound that put wheat germ on the research map. Spermidine is found in mushrooms, aged cheese and fermented foods — and it's become one of the most-studied nutrients in the science of ageing. We include 50mg per serving, so you don't have to live on natto.
Pine Bark Extract (PCOs)
From the forests of southwest France. Maritime pine bark extract has been a staple of European phytotherapy for decades — 100mg of standardised extract rounds out the formula.
About Brittica Vitality
We Go Beyond Symptoms
Most supplements treat the surface. We built Brittica Vitality to go deeper. Every formula starts with one question: what does the cell actually need? Not what is trending on social media. Not what sounds impressive on a label. What the peer-reviewed literature says works — at the dose it says works.
Science-Backed. Clinically Dosed.
Every ingredient in Ca-AKG+ is present at the dose shown effective in human studies. No pixie dust. No proprietary blends hiding suboptimal quantities. We publish our full formulation because we have nothing to hide. The starting point is the research. The end point is how you feel.
The Whole Picture
Your body is not a collection of isolated systems. It is an integrated network — when one pathway slows, the rest feels it. That is why Ca-AKG+ combines seven ingredients in one daily formula: calcium, vitamin D, vitamin K and magnesium contribute to the maintenance of normal bones; magnesium contributes to normal energy-yielding metabolism and the reduction of tiredness and fatigue; and vitamin D contributes to the normal function of the immune system. Alongside these, PQQ, CoQ10, hydroxytyrosol, spermidine and pine bark complete the formula — one bottle, the whole picture.
“We design formulas that dive deep — targeting the root processes that keep your body thriving, not just functioning.”
— The Brittica Vitality Commitment
Ca-AKG+ is our first formula. It will not be our last. Every product we release will meet the same standard: transparent labelling, clinical doses, and ingredients that do something real. Your body deserves better than hope.
The Science
The Research Behind Every Capsule
Alpha-ketoglutarate (AKG) is a compound your body produces naturally, and it plays a role in the Krebs cycle — the process your cells use to convert nutrients into energy. Research has shown that natural AKG levels decline with age, particularly from mid-life onwards.
Ca-AKG+ delivers 1,000mg of 99% pure Calcium AKG, supported by six co-factors. Calcium, vitamin D, vitamin K and magnesium contribute to the maintenance of normal bones. Magnesium also contributes to normal energy-yielding metabolism and the reduction of tiredness and fatigue, while vitamin D contributes to the normal function of the immune system. Alongside these, the formula includes PQQ, CoQ10, hydroxytyrosol from olive leaf, spermidine from wheat germ, and French maritime pine bark extract — nutrients studied for their roles in cellular processes. Every ingredient is included at a clearly stated dose, with no proprietary blends.
