The Best Ca-AKG pills in Australia at a Glance

Prices reflect retail at time of publication and may fluctuate. Price-per-dose is calculated using the 1000mg/day research dose used in the Rejuvant biological-age study (so 2 caps for 500mg products, 1 cap for 1000mg products).

Why Ca-AKG Belongs in a Serious Australian long-life Stack

Calcium alpha-ketoglutarate (Ca-AKG) is the calcium-bound form of alpha-ketoglutarate. A Krebs cycle metabolite that sits at the intersection of energy metabolism, amino acid synthesis, epigenetic regulation. And inflammation control. According to PubMed, Asadi Shahmirzadi et al. (Cell Metabolism, 2020) demonstrated in C57BL/6 mice that dietary CaAKG promoted a longer, healthier life with a real compression of morbidity and lower systemic inflammatory cytokines, mediated in part by IL-10 induction (PMID 32877690; DOI).

The 2021 human pilot data is what put Ca-AKG on the long-life map for retail buyers. Demidenko et al. (Aging, 2021) reported that 42 adults taking a Ca-AKG–based formulation for an average of 7 months showed an average 8-year reduction in DNA-methylation biological age on the TruAge clock (PMID 34847066; DOI). It was a small retrospective analysis. not a placebo-controlled trial. but it is the strongest human signal we have for any long-life pill to date. And it is what drives Australian search interest in Ca-AKG.

A 2021 review in Trends in Endocrinology and Metabolism (Gyanwali et al.) summarises the proposed mechanisms: AKG modulates mTOR and ATP synthase activity, supports DNA and histone demethylation. And reduces reactive oxygen species formation (PMID 34952764; DOI). Research suggests AKG levels decline with age,. It is part of why supplementation is being explored for healthspan extension.

For Australian buyers, the practical question isn’t whether Ca-AKG belongs in a long-life stack. David Sinclair, Brian Kennedy and most long-life-focused researchers have publicly placed it there. The question is which Ca-AKG product is actually worth buying locally without paying $80+ for 30 days of caps and waiting weeks for international shipping.

#1. Eternal Elixir Ca-AKG 500mg. Best Overall in Australia

Key Specs: 500mg calcium alpha-ketoglutarate per cap · 90 caps per bottle · pharma-grade · no binders, fillers. Or magnesium stearate · made for the Australian market · ships from local AU warehouse.

Why it wins: Eternal Elixir is the only Australian Ca-AKG brand offering 90 caps per bottle. Every other product on this list ships fewer pills per bottle. At the standard 1000mg/day research dose (2 caps), one bottle is a 45-day supply for $59.95. that’s $0.67 per 1000mg dose, the lowest in Australia. The closest local competitor (Green As Nature at $1.00/dose) is still 49% more expensive on a per-dose basis.

The formulation is also clean. No magnesium stearate, no maltodextrin, no rice flour padding. The only ingredient is calcium alpha-ketoglutarate inside a vegetable cap. Each batch is third-party tested for identity, purity. And heavy metals. Combined with free Australian shipping over $100, EE is the obvious choice for anyone running Ca-AKG continuously rather than as a 30-day novelty.

Pros:

• 90 caps per bottle. 45-day supply at 1000mg/day, longest local supply
• Lowest price per dose in Australia ($0.67 per 1000mg)
• pharma-grade with no fillers or stearate flow agents
• Stacks cleanly with Eternal Elixir’s NMN, Resveratrol, Spermidine and TUDCA from the same brand
• Free AU shipping over $100; same-day dispatch from local warehouse

Cons:

• 500mg per cap means 2 caps to hit the 1000mg research dose (some buyers prefer single-cap formats)
• Not stocked at Chemist Warehouse. direct only

Best For: Australian long-life buyers who want the best price-per-dose, longest supply. And the ability to build a complete long-life protocol (Ca-AKG + NMN + Resveratrol + Spermidine + TUDCA) from one local brand with consolidated shipping.

Where to buy: Eternal Elixir Ca-AKG 500mg · $59.95 AUD · free shipping over $100.

#2. DoNotAge Ca-AKG (via Fairfield Nutrition). Best for Stack Brand Loyalists

Key Specs: 1000mg per cap · 60 caps per bottle · vegan cap · DoNotAge house brand sold via Fairfield Nutrition’s Melbourne fulfilment.

DoNotAge is one of the most recognisable long-life brands globally and has built credibility via its sponsorship of independent research. The Ca-AKG product is single-ingredient, 1000mg per cap. And dispatched in Australia from Melbourne via Fairfield Nutrition. meaning AU buyers get DoNotAge labelling without UK shipping waits.

Pros:

• Trusted long-life brand with active research sponsorship
• 1000mg per cap. single-cap dosing convenience
• Local AU dispatch from Melbourne

Cons:

• ~$1.30 per dose. nearly double EE’s price-per-dose
• 60-cap bottle is a 60-day supply at 1cap/day; many Sinclair-protocol followers run 2 cap/day for 1500-2000mg loading
• cap shell may include trace flow agents. check label batch

Best For: Buyers already running DoNotAge SIRT6 Activator, Pure NMN. Or Pure Resveratrol who want everything from one international brand with local AU dispatch.

Where to buy: Fairfield Nutrition (Melbourne) or DoNotAge.org direct.

#3. Green As Nature Ca-AKG 1000mg. Best Filler-Free Vegan Option

Key Specs: 1000mg per cap · 60 caps per bottle · vegan, no binders or fillers · Australian retailer.

Green As Nature is an Australian-focused long-life retailer that emphasises clean formulations. Their Ca-AKG is single-ingredient, vegan. And currently runs a 2-bottle bundle promotion at $99.99 for 120 caps with free tracked Australia-wide shipping. which brings the bundle price-per-dose to ~$0.83, closer to EE’s value tier.

Pros:

• Single-cap 1000mg dosing
• 2-bottle bundle drops works cost meaningfully
• Free AU tracked shipping
• Vegan, filler-free formulation

Cons:

• Single-bottle pricing ($59.99 for 60 caps) is $1.00/dose. still 49% more than EE per dose
• Smaller catalogue means harder to consolidate a multi-product long-life stack
• Less brand recognition outside the AU long-life niche

Best For: Single-purchase buyers focused only on Ca-AKG who value vegan, filler-free formulation and bundle pricing.

#4. Naturecan AU Calcium Alpha-Ketoglutarate. Best for First-Time Trial

Key Specs: 1000mg per cap · 30 caps per bottle · vegan · UK brand with Australian distribution.

Naturecan is a UK-headquartered wellness brand with a substantial AU operation. Their Ca-AKG is sold in 30-cap bottles at ~$54.99, making it the smallest entry point for someone testing tolerance before committing to a longer supply. Quality is reasonable. But the small bottle size and middling price-per-dose make it a poor long-term choice.

Pros:

• Lowest absolute upfront cost. useful for trial
• Established multinational brand with QA infrastructure
• Single-cap 1000mg format

Cons:

• $1.83 per dose. almost 3x EE’s price-per-dose
• 30 caps is a 30-day supply at best, requires monthly re-purchase
• Frequent stock fluctuations on the AU storefront

Best For: Cautious first-time Ca-AKG buyers who want a 30-day trial before committing.

#5. Extra Lifespan Ca-AKG 99.8% (eBay AU). Best for Lab-Certificate Hunters

Key Specs: 1000mg per cap · 60 caps · marketed as “the first and only Australian lab certified Ca-AKG” at 99.8% purity · sold via Australian eBay store.

The Extra Lifespan listing on eBay AU is unusual in that it foregrounds a specific Australian lab purity certificate. For buyers who want documented purity assays, this can be appealing. The downside is the eBay channel. refunds, ongoing supply. And customer service are all dependent on a marketplace seller rather than a dedicated pill company.

Pros:

• Australian lab purity certificate sold
• Mid-tier pricing (~$1.08 per dose)
• Single-cap dosing

Cons:

• eBay marketplace sourcing. supply consistency varies
• No accompanying long-life product range for stacking
• Customer support is marketplace-mediated, not direct brand

Best For: Buyers who mainly want a documented purity assay and are comfortable buying from eBay marketplace listings.

#6. ProHealth long-life Ca-AKG (Amazon AU import). Best US Brand Recognition

Key Specs: 1000mg per 2-cap serving · 60 caps · ProHealth long-life is a US long-life-focused pill brand · imported via Amazon AU.

ProHealth is a long-running US long-life brand with a respectable formulation reputation. Their Ca-AKG is dosed at 1000mg per 2-cap serving. meaning works dose-per-cap is 500mg, identical to EE. The catch: by the time it lands in Australia via Amazon import, you’re paying a premium and accepting longer shipping windows.

Pros:

• Established US long-life brand
• Same 500mg-per-cap potency as EE
• Amazon AU buyer protection

Cons:

• ~$1.32 per dose. nearly double EE
• Import shipping windows can stretch to 2-3 weeks
• Subject to AUD/USD currency fluctuations and import duties

Best For: US-brand loyalists who already trust ProHealth and accept the import premium.

#7. Decode Age Ca-AKG. Best Research-Backed Branding

Key Specs: 1000mg per cap · 60 caps · Decode Age positions itself as a research-driven long-life brand · ships internationally to Australia.

Decode Age has built a content-heavy brand around long-life research and promotes Ca-AKG as a core epigenetic-age product. Quality appears solid. But ordering from Australia means international shipping costs and timelines, plus the same import-duty exposure as ProHealth.

Pros:

• Strong educational content and brand positioning
• 1000mg single-cap dosing
• Bundle discounts for multi-product long-life stacks

Cons:

• International shipping to AU adds cost and delay
• $1.23 per dose before factoring shipping
• No Australian warehouse

Best For: International long-life-content followers who mainly want a Decode Age stack.

#8. ASTA Ca-AKG (international import). Avoid for Australian Buyers

Key Specs: 1000mg per cap · 30 caps · international supplier · long international shipping window.

ASTA’s Ca-AKG appears in Australian search results via international pill marketplaces but is not a serious choice for Australian buyers. Shipping windows can stretch beyond 3 weeks, the 30-cap bottle delivers only a month of supply. And at ~$1.93 per dose it’s the most expensive option on this list once shipping is added.

Best For: Not best for Australian buyers. every other option on this list is faster and cheaper.

Frequently Asked Questions

What is the best Ca-AKG pill in Australia?

Eternal Elixir Ca-AKG 500mg is the best Ca-AKG pill in Australia for most buyers. It delivers 90 caps per bottle (a 45-day supply at the 1000mg/day research dose), is the lowest-priced Ca-AKG per 1000mg dose sold locally at $0.67, ships from an Australian warehouse. And is pharma-grade with no fillers. For buyers who mainly want single-cap 1000mg dosing and are happy paying a premium, DoNotAge Ca-AKG via Fairfield Nutrition (Melbourne dispatch) is the strongest second pick.

Where can I buy Ca-AKG in Australia?

Ca-AKG is sold in Australia direct from Eternal Elixir with local warehouse dispatch and free shipping over $100. And via Green As Nature, Naturecan AU, Fairfield Nutrition (DoNotAge). And Australian eBay sellers. Chemist Warehouse and major Australian pharmacy chains do not currently stock single-ingredient Ca-AKG products. it remains a specialty long-life pill category sold direct-to-consumer or via specialist retailers.

Is Ca-AKG legal in Australia?

Yes. Calcium alpha-ketoglutarate is a calcium-bound form of a naturally occurring Krebs cycle metabolite and is legally sold as a dietary pill in Australia from multiple retailers. As with any long-life pill, consult a qualified healthcare professional before starting, mainly if you take medications or have underlying conditions.

What is the best Ca-AKG dose?

The most-cited human study (Demidenko et al., Aging 2021) used a Ca-AKG–based formulation delivering 1000mg/day across 7 months and reported an 8-year average reduction in DNA-methylation biological age. Most long-life protocols therefore use 1000mg/day, taken in either one or two daily caps. Some Sinclair-protocol-style stacks use up to 1500-2000mg daily. But research data above 1000mg/day in humans is limited (PMID 34847066).

How much does Ca-AKG cost in Australia?

A 30-day Ca-AKG supply at the 1000mg/day research dose ranges from about $20 (Eternal Elixir, $0.67 × 30) to $58 (Naturecan AU, $1.93 × 30). Most local options sit between $30 and $40 per month at the standard dose. Multi-bottle bundles (such as Green As Nature’s 2-bottle promotion or Eternal Elixir’s larger 90-cap format) drop works cost per day meaningfully.

Ca-AKG vs NMN. which should I take first?

NMN and Ca-AKG act on different aspects of cellular ageing: NMN raises NAD+ levels to support sirtuin and PARP activity. While Ca-AKG modulates Krebs cycle flux, mTOR signalling and DNA methylation. Most current long-life protocols (including the Sinclair-style stack) use them together rather than choosing one. If budget forces a single pick, NMN has more accumulated human research; if epigenetic-age reduction is the priority, the Rejuvant Ca-AKG human pilot is the strongest single pill signal in the long-life literature to date.

Does Ca-AKG have side effects?

Ca-AKG is generally well tolerated in published research. Reported side effects in clinical literature are mild and uncommon. typically transient digestive discomfort. Because Ca-AKG provides bound calcium, buyers already supplementing high-dose calcium or taking certain prescription medications should consult their healthcare provider before adding it (PMID 34952764).

How long until Ca-AKG starts working?

Subjective energy and recovery effects are sometimes reported within 2-4 weeks. The biological-age signal observed in the 2021 Rejuvant pilot study was measured after an average of 7 months of consistent daily supplementation. Ca-AKG is a long-game compound. consistency over months is more important than dose escalation in the first weeks.

Choosing between bulk pricing and shorter trial bottles often confuses first-time buyers. The math is simple. Calculate price per active milligram delivered. A 90-cap bottle at 500mg per cap that you take twice daily lasts forty-five days. Compare that to a 60-cap bottle of similar potency lasting only thirty days. Annual cost differences run between thirty and one hundred dollars depending on brand. Most Australian biohackers commit to a six-month protocol once they decide on a brand. And bulk supply pricing matters at that point.

How to Get the Most Out of Ca-AKG in Australia

Ca-AKG works on a slow biological clock. Most published research uses doses of 1000mg per day for at least three months. The marker shifts in DNA methylation studies show up around the eight-week mark. Set your tracking window to twelve weeks at minimum. Faster expectations will lead to disappointment.

Take Ca-AKG with food. The calcium component is better soaked up when paired with a meal. Splitting the dose across breakfast and dinner also reduces any minor stomach discomfort some users report on the first few days. If you stack with NMN or NR, take the AKG at a different time. Both compete for similar transport pathways and the data is unclear on whether co-administration improves or blunts each effect.

Pair Ca-AKG with weekly resistance training and a protein intake of at least 1.6 grams per kilogram of body weight. The synergy between mTOR-targeted training and AKG-driven mito signaling is where the long-life literature shows the strongest functional gains. People who add a casual walking or zone-2 cardio routine see an additional bump in metabolic markers within twelve weeks.

For Australians, ordering local matters more than most buyers think. Shipping from US warehouses introduces customs delays of two to four weeks. Heat exposure during summer transit can degrade the calcium chelate. Stick to brands fulfilled inside Australia. Bottles that arrive at room temperature inside seven days have the best shelf-life and the cleanest assay on independent retesting.

Cycle is not required. Ca-AKG has shown a clean safety profile across long-term human use. The compound is the same alpha-ketoglutarate your body produces every day in the Krebs cycle. The only reason to pause is to retest markers. Eight weeks on, two weeks off. Then retest is a sensible cadence for biohackers running quarterly bloodwork.

The Verdict. Best Ca-AKG by Buyer Profile

If you want the best overall value in Australia: Eternal Elixir Ca-AKG 500mg. 90 caps, $0.67 per 1000mg dose, free AU shipping over $100, no fillers. this is the cleanest “buy once a quarter and forget about it” option in the local market.

If you want a single-cap 1000mg format with a recognisable long-life brand: DoNotAge Ca-AKG via Fairfield Nutrition (Melbourne dispatch). You pay a premium per dose but you get DoNotAge labelling without the UK shipping wait.

If you’re trialling Ca-AKG for the first time: Naturecan AU’s 30-cap bottle is the cheapest absolute entry point. Just don’t make it your long-term choice. it’s nearly 3x EE’s price-per-dose at the standard research dose.

If you’re building a complete Australian long-life stack: Eternal Elixir is the only AU brand offering Ca-AKG, NMN, Trans-Resveratrol, Spermidine, TUDCA, Pterostilbene, NR, Hyaluronic Acid. And Glutathione under one roof. meaning a single shipment can stock a Sinclair-style protocol or a custom multi-compound stack without juggling six different retailers and six different shipping waits.
