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

The Foundation1,000mg

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.

Bone Support50mcg + 60mcg

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.

Cell Nutrients20mg + 50mg

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.

Energy & Fatigue125mg

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.

Olive Polyphenol50mg

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.

Wheat Germ Extract50mg

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.

Maritime Pine100mg

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.

Questions & Answers

Everything You Need to Know

Ca-AKG is Calcium Alpha-Ketoglutarate — a form of a molecule your body already makes. Its job is to sit in the Krebs cycle and help turn the food you eat into usable energy. Here's the catch: your body makes less of it as you get older. By the time you hit your 50s and 60s, you have already lost a meaningful amount — and the decline keeps going from there. Ca-AKG+ simply puts it back, along with six other ingredients that support the same energy pathways.

Think of it as your cell's power station. It's a chain of chemical reactions inside your mitochondria that converts the food you eat into ATP — the energy currency your body runs on. AKG sits at a key step in that chain. When AKG drops, the whole line slows. That's why topping it back up matters.

Regular AKG (often sold as ornithine AKG) is acidic and harder for your body to hold onto. The calcium salt form is absorbed better, lasts longer in your system, and is easier on your stomach. Plus you get the calcium itself — which supports bone maintenance. Most of the published research on AKG and ageing used the calcium form specifically.

They are different compounds that have been studied in different contexts. NMN is a precursor the body converts into NAD+. Ca-AKG is a form of alpha-ketoglutarate, a compound the body produces and uses directly. Some people choose to take both; others prefer a single product. If you are unsure which suits you, we suggest discussing it with a healthcare professional.

Take 2 capsules daily with water, preferably with a meal. Each bottle contains 60 capsules — a 30-day supply. Food supplements work best as a consistent daily habit alongside a varied, balanced diet and a healthy lifestyle.

Give it two to four weeks before you judge it. Some people feel a difference sooner — more consistent energy, less afternoon slump. For others it takes longer. The published studies ran for three to six months, so that is the real timeframe to think about. It is not a stimulant. You won't get a caffeine-style rush. The change is quieter: you just keep going when you used to flag.

Yes. Your body already makes AKG every day. You also get it from food — spinach, meat, dairy. The 1,000mg daily dose in Ca-AKG+ is within the range researchers have studied in human trials. That said, Ca-AKG+ is a food supplement, not a medicine. It is not intended to diagnose, treat, cure, or prevent any disease. If you are unsure, talk to your doctor first.

Most people handle it fine. A few get mild stomach adjustment in the first few days — taking it with food usually sorts that out. If you are on prescription medication, pregnant, breastfeeding, or have a health condition, check with your doctor before starting. And if something does not feel right, stop taking it and get advice.

It plays well with most things — vitamin D, omega-3, magnesium, probiotics. The one caveat is blood-thinning medication: the K2 in our formula can interact with those, so speak to your doctor if that applies to you. Otherwise, if you are on regular medication, a quick check with your doctor or pharmacist is sensible.

Adults 18 and over who want to support their energy, bones, and general vitality. It is especially relevant from your 40s onward — that is when AKG levels really start to drop. Not for children. Not if you are pregnant or breastfeeding. And if you have a medical condition, talk to your doctor first.

Most AKG supplements contain only alpha-ketoglutarate. Ca-AKG+ uses the calcium salt form and adds six co-factors: vitamin D3 + K2 (vitamin D and vitamin K contribute to the maintenance of normal bones), magnesium glycinate (magnesium contributes to normal energy-yielding metabolism and the reduction of tiredness and fatigue), plus PQQ, CoQ10, hydroxytyrosol, spermidine and French maritime pine bark — nutrients studied for their roles in cellular processes. No proprietary blends. Every dose listed. Every ingredient justified.

Ca-AKG+ is manufactured in a GMP-certified facility. Every batch is third-party tested for purity, potency, and contaminants before it reaches you. We do not cut corners on quality.
