In short
SDAI BioAge is a premium sustained-release calcium alpha-ketoglutarate supplement with gender-specific cofactor blends, aimed at Asia-Pacific markets. The delivery format addresses a real pharmacokinetic problem. The underlying ingredient has early-stage human evidence. It suits people whose lifestyle fundamentals are already handled, and does not suit people looking for a shortcut past them.
Disclosure. This site is brand-operated. We have written this review to state limitations alongside strengths, because an unqualified positive review from the brand's own property is worthless to a reader and obvious to anyone paying attention. Weigh it accordingly and run the checks in our verification guide.
What it is
A calcium alpha-ketoglutarate supplement in a sustained-release format, with separate men's and women's formulations that share the same active compound and differ in supporting micronutrients. The supporting blend includes B-group vitamins, folate, vitamin A and vitamin D3. Sold at a premium price point, with distribution focused on Asia-Pacific markets.
What the formulation gets right
The delivery problem is real
Alpha-ketoglutarate clears quickly. An immediate-release dose produces a short plasma peak, which is a poor fit for a compound whose proposed benefit involves acting as an enzyme cofactor. Sustained release is a rational engineering answer, not an invented differentiator.
The verification step: ask for the dissolution profile. Release behaviour is measurable in a laboratory, and a manufacturer confident in the format can produce the curve. We would apply that standard to any brand making this argument, including this one.
Cofactor rationale is coherent
The B-vitamin and micronutrient additions are a defensible formulation choice rather than an arbitrary one, though whether cofactor addition improves outcomes has not been separately established.
Where a buyer should apply scrutiny
The ingredient's evidence is early stage
This is not specific to SDAI, it applies across the entire category. The human evidence for calcium AKG is one retrospective uncontrolled analysis of 42 self-selected people, plus observational cohort associations, plus good mouse data. No randomised controlled trial has reported biological age outcomes for any Ca-AKG product.
Any brand in this category presenting the compound as clinically proven is overstating it. Our full read is on the evidence page.
No study exists on this specific formulation
SDAI BioAge™ has no published research on its own product. Nor do most brands in the category. The exception is Rejuvant, which was the product in the 2021 analysis, and that association carries its own heavy caveats. A comparison is at SDAI BioAge vs Rejuvant.
Premium pricing needs premium documentation
A premium price is justifiable when it buys verifiable things: a documented release profile, batch-specific third-party testing, certified manufacturing, and a dose at the researched level. It is not justifiable on positioning alone. Ask for the documents before you accept the price.
Who it suits
- People whose fitness, sleep, body composition and smoking status are already in good shape, and who are looking at genuinely marginal options
- Buyers who accept the sustained-release argument and want regional supply rather than international shipping
- People comfortable spending discretionary money on an early-stage intervention with eyes open
Who it does not suit
- Anyone looking for a substitute for the lifestyle levers. On every biological age model we know of, those dominate anything a supplement contributes, and it is not close.
- Buyers who want proven clinical efficacy. That does not exist for this compound yet, from any brand.
- Anyone for whom the cost is not genuinely discretionary.
- People who would get better value from a standard blood panel and a gym membership. That is a large group.
The verdict, stated honestly
This is a well-formulated product in a category whose evidence base is thinner than its marketing generally implies. The sustained-release approach addresses a real problem. The ingredient is a plausible early-stage candidate, not a demonstrated intervention.
If you buy it, buy it as an adjunct to fundamentals you already have handled, not as a replacement for fundamentals you do not. That is the only recommendation the evidence currently supports, and it is the one we would give about any product in this category.

Common questions
Does SDAI BioAge work?
The honest answer is that the compound has a coherent mechanism, good animal data and thin human data, and no randomised controlled trial has reported biological age outcomes for any Ca-AKG product. Nobody can currently tell you it works in the sense that word usually implies.
How long before I notice anything?
Subjective changes people report in the early weeks are not measurable biological age change and should not be read as such. The only way to know whether a biological marker shifted is to measure before and after, allowing at least several months, and even then a single methylation reading carries substantial noise.
Is it worth the premium price?
Only if the premium buys documented things: a real dissolution profile, batch-specific third-party testing, certified manufacturing, and a dose at the researched level. Ask for those before accepting the price. If they are not forthcoming, the premium is buying positioning.
Should I take this instead of exercising more?
No, and no reading of the evidence supports that trade. Cardiorespiratory fitness is among the largest modifiable inputs on every biological age model we are aware of. A supplement does not substitute for it.
