M98 Resveratrol Complete: Resveratrol PICEID (Polydatin), the Solution to Resveratrol's Bioavailability Problem (2026)
In short: Standard trans-resveratrol is well absorbed but barely dissolves in water, and what does get in is converted so fast that only trace amounts of free resveratrol reach the blood (Walle 2004). M98 Resveratrol Complete uses Resveratrol PICEID (Polydatin, Trans-Resveratrol-3-O-glucoside), the natural glucoside form of resveratrol. It is up to 25x more water-soluble, it is taken up in part by the SGLT1 glucose transporter, and in animal studies it was the main form of resveratrol circulating in the blood, raised SIRT1 activity on its own, and outperformed resveratrol on antioxidant enzymes.*
Resveratrol PICEID (Polydatin) vs Standard Resveratrol: Complete Comparison (2026)
The choice between polydatin (Trans-Resveratrol-3-O-glucoside) and standard resveratrol comes down to one question: which form does your body actually work with? Every row below is tied to a published study, numbered to the references at the end of this page.
M98 Polydatin vs Standard Resveratrol: Head-to-Head Comparison
| Feature | M98 Resveratrol PICEID (Polydatin) | Standard Resveratrol |
|---|---|---|
| Water Solubility | About 0.5 to 0.7 mg/mL: up to 25x higher [10] | About 0.015 to 0.05 mg/mL [11] |
| Intestinal Uptake | SGLT1 glucose transporter plus passive diffusion [2] | Passive diffusion only [2] |
| Main Circulating Form After Oral Dosing | Polydatin (animal study) [4] | Trace free resveratrol in human plasma [9] |
| Time in Circulation | Oral half-life about 3 to 4.5 hours (rats) [12] | Free resveratrol cleared in minutes (rats) [13] |
| Sirtuin Activity | Raised SIRT1 activity on its own (rats); restored SIRT3 activity (human cells) [14][16] | Activates SIRT1 [8] |
| Antioxidant Enzymes (SOD, CAT, GSH) | Outperformed resveratrol (animal study) [4] | Effective, but less than polydatin [4] |
| Molecular Form | Glycosylated (glucose-attached) | Free aglycone |
The glucose molecule attached to polydatin makes it far more water-soluble and lets intestinal glucose transporters recognize it. Recent peer-reviewed papers describe polydatin as having higher intestinal absorption and improved bioavailability compared with resveratrol [15].
Solubility math: published baselines put polydatin near 0.5 mg/mL (measured at 0.56 to 0.71 mg/mL [10]) and trans-resveratrol at about 0.015 to 0.05 mg/mL [11]. Using 0.02 mg/mL as a practical midpoint gives the 25x comparison.
Short version: Polydatin is the glucoside form of resveratrol. It is up to 25x more water-soluble, it is taken up partly by the SGLT1 glucose transporter, and in animal studies it was the main form circulating in the blood, stayed in circulation for hours, raised sirtuin activity on its own, and beat resveratrol on antioxidant enzymes.*
6 Steps to Selecting a Bioavailable Resveratrol Supplement (2026)
Resveratrol products vary a lot. Here is what we look at when comparing them:
What to Check
- Check the Molecular Form: Look for Resveratrol PICEID (Polydatin, Trans-Resveratrol-3-O-glucoside) rather than standard trans-resveratrol. The glycosylated form is far more water-soluble and is recognized by intestinal glucose transporters [2][10].
- Verify Absorption Claims: Ask for the study behind any number. Absorption and bioavailability are different things: standard resveratrol is largely absorbed, but only trace amounts of free resveratrol reach the blood [9]. Be wary of any brand quoting a single absorption percentage without a citation.
- Consider Time in Circulation: Free resveratrol is cleared within minutes in animal studies [13]. Oral polydatin had a half-life of roughly 3 to 4.5 hours in rats [12], and polydatin was the main form circulating after oral dosing [4].
- Evaluate the Transport Mechanism: Better solubility helps, but transport matters too. In intestinal cell studies, polydatin is taken up partly through the SGLT1 glucose transporter as well as passive diffusion, while resveratrol relies on passive diffusion alone [2].
- Compare Solubility as Well as Milligrams: A large label dose of a compound that barely dissolves is not the same as a dose that disperses. Polydatin dissolves at up to 25x the rate of trans-resveratrol [10][11], which is why M98 is built on it.
- Review Quality Standards: Choose supplements from manufacturers who provide third-party testing, transparent labeling, and evidence-based claims with citations. RevGenetics has published Certificates of Analysis since 2007.
Quick Decision Guide: Which Resveratrol Supplement?
Choose M98 Resveratrol Complete if you:
- ✓ Want the water-soluble glucoside form of resveratrol (up to 25x more soluble)
- ✓ Want the form that circulated longest and raised sirtuin activity on its own in animal studies
- ✓ Prefer powder format for flexible dosing
- ✓ Value research-backed formulations
- ✓ Understand effective dose matters more than label dose
Standard resveratrol might suit you if you:
- ✗ Prioritize lowest cost over effectiveness
- ✗ Prefer capsules regardless of absorption limitations
- ✗ Want to match exact doses used in cell culture studies (not meaningful for human use)
Why Most Resveratrol Supplements Underperform: The Absorption Problem
Resveratrol drew a lot of attention when lab studies showed it could activate sirtuins and extend lifespan in simple organisms. Plenty of people started taking it, and many noticed little.
The reason is not that resveratrol fails to get in. In a human study using labeled resveratrol, at least 70% of a 25 mg oral dose was absorbed, yet only trace amounts of unchanged resveratrol (under 5 ng/mL) showed up in plasma [9]. Resveratrol dissolves poorly, and the portion that is absorbed is converted almost immediately.
That gap between absorption and bioavailability explains the disconnect between promising laboratory results and underwhelming real-world outcomes. Cells in a petri dish receive the full dose researchers apply. Cells in your body receive mostly metabolites.
Why Standard Resveratrol Absorption Fails
Three things work against standard resveratrol:
Poor Solubility: Trans-resveratrol dissolves poorly in water. Since your digestive tract is an aqueous environment, the compound clumps together rather than dispersing for absorption. Reduced surface area means reduced uptake.
Rapid Metabolism: Any resveratrol that does get absorbed faces immediate attack. Enzymes in your intestinal wall and liver convert the compound into metabolites before it can reach circulation. This first-pass metabolism destroys most of what the gut absorbs.
Brief Time in Circulation: Free resveratrol is cleared within minutes in animal studies [13]. Polydatin, by contrast, had an oral half-life of roughly 3 to 4.5 hours in rats [12], and in a head-to-head animal study it was the main form circulating in the blood after oral dosing [4].
What is Resveratrol PICEID (Polydatin)?
Resveratrol PICEID (Polydatin), chemically Trans-Resveratrol-3-O-glucoside, is a naturally occurring glycoside form of resveratrol. It is the same compound some red grape supplements list on their labels as "piceid resveratrol" or "resveratrol piceid". The compound consists of a resveratrol molecule bonded to a glucose molecule at the 3-position.
This structural change gives resveratrol a sugar handle. It makes the molecule far more water-soluble [10], and in intestinal cell studies it allows uptake through the SGLT1 glucose transporter in addition to passive diffusion [2]. Polydatin and resveratrol interconvert in the body, and in animal studies polydatin was the predominant form in the blood [4].
Polydatin occurs naturally in Japanese knotweed (Polygonum cuspidatum), grapes, peanuts, and several other plants. Traditional Chinese medicine has used Japanese knotweed extracts containing polydatin for centuries, long before modern science understood the absorption advantages.

How Does M98's Dual Transport Technology Work?
M98 Resveratrol Complete is designed to enter your body through two pathways at once: passive diffusion, helped by much higher water solubility, and active uptake through glucose transporters. Standard resveratrol relies on passive diffusion alone [2].
Passive Diffusion Pathway
Like standard resveratrol, polydatin can cross cell membranes by passive diffusion. Because polydatin is up to 25 times more water-soluble than trans-resveratrol [10][11], more of it can dissolve in the watery environment of the gut and become available for uptake.
Active Transport via SGLT1
In studies using human intestinal cells, the uptake of polydatin was linked to the sodium-dependent glucose transporter 1 (SGLT1), which recognizes the glucose attached to polydatin. Standard resveratrol has no glucose and enters only by passive diffusion [2]. SGLT1 is found mainly in the small intestine, where it absorbs dietary sugars.
Once inside intestinal cells, part of the polydatin is converted to resveratrol and its conjugates [3]. The two forms continue to interconvert after absorption, and in animal studies polydatin was the main form circulating in the blood [4].
What the Research Says
Recent peer-reviewed papers describe polydatin as having "higher intestinal absorption due to the presence of its sugar groups" and "improved bioavailability" compared with resveratrol [15], and as having better water solubility and stability than resveratrol [17].
Research Background
From the published studies: Henry et al. (2005, J Agric Food Chem) found that trans-piceid (polydatin) uptake in human intestinal Caco-2 cells is likely active and involves SGLT1, while trans-resveratrol uses passive transport [2]. Henry-Vitrac et al. (2006, Eur J Nutr) showed that polydatin crossing intestinal cells is converted to resveratrol and its conjugates [3]. Wang et al. (2015, Phytomedicine) found polydatin was the main form in the blood after oral dosing in animals, and that it outperformed resveratrol on antioxidant enzymes [4].

What Are Sirtuins and Why Does Sustained Activation Matter?
Sirtuins are a family of seven proteins (SIRT1-SIRT7) that regulate core processes inside cells. They influence DNA repair, inflammation, metabolism, stress resistance, and aging pathways. They are often called longevity genes because of their link to lifespan in studies ranging from yeast to mammals.
Resveratrol gained fame as a sirtuin activator. Laboratory studies showed the compound could trigger SIRT1 activity and produce effects resembling caloric restriction, the only intervention consistently shown to extend lifespan in diverse organisms.
The Timing Problem
Polydatin does more than turn into resveratrol. In a rat study, polydatin itself increased SIRT1 enzyme activity, and its effects disappeared when SIRT1 was blocked [14]. A 2024 mouse study likewise found polydatin's effects depended on SIRT1 [17]. In human fibroblasts with impaired mitochondrial function, polydatin restored SIRT3 enzyme activity in the mitochondria, and its benefits were lost when a SIRT3 inhibitor was added [16]. A 2024 review of sirtuin modulators lists polydatin as an activator of both SIRT1 and SIRT3 [18].
Why we believe polydatin extends the window: Polydatin engages SIRT1 on its own [14], stayed in circulation for hours after oral dosing in rats [12], and converts over time to resveratrol [3], the best-known SIRT1 activator [8]. Engaging sirtuins both as polydatin and as the resveratrol it becomes is the design rationale for M98. A head-to-head human study of sirtuin activation duration has not yet been published.
Downstream Benefits of Sustained Sirtuin Activation
- Enhanced Mitochondrial Function: SIRT1 activation promotes mitochondrial biogenesis through PGC-1α, improving cellular energy production
- Improved Metabolic Health: Sirtuin signaling influences glucose metabolism, insulin sensitivity, and lipid handling
- DNA Repair Support: SIRT6 participates directly in DNA damage response and genomic stability
- Inflammation Modulation: Sirtuin activity helps regulate inflammatory pathways through NF-κB interactions
- Cellular Stress Resistance: Activated sirtuins enhance cellular defenses against oxidative and metabolic stress

Can M98 Resveratrol Complete Be Combined with Other Longevity Supplements?
M98 Resveratrol Complete pairs well with several other longevity supplements. Many customers take it alongside the products below.
Complementary Combinations
With NMN Supplements: NMN boosts NAD+ levels while resveratrol activates sirtuins that require NAD+ as a cofactor. This combination provides both the fuel (NAD+) and the activation signal (resveratrol) for sirtuin activity.
With EGCG 800: EGCG activates autophagy through AMPK and mTOR pathways. Combined with M98's sirtuin activation, this addresses both cellular cleanup (autophagy) and cellular repair (sirtuins) for cellular health.
With MetaCurcumin: Curcumin provides anti-inflammatory support through NF-κB modulation. Since chronic inflammation accelerates aging, combining curcumin's anti-inflammatory effects with M98's sirtuin activation addresses two major aging drivers.
With Senolytic Supplements: Senolytics clear senescent cells while M98 supports healthy cell function. This combination removes damaged cells while optimizing the cells that remain.
M98 fits alongside NMN (NAD+ support), EGCG (autophagy), curcumin (inflammation) and senolytics (senescent cells). Talk to a healthcare provider before starting any supplement routine.
Frequently Asked Questions About M98 Resveratrol Complete
What is Resveratrol PICEID?
Resveratrol PICEID, also called Polydatin or piceid resveratrol, is trans-resveratrol-3-O-glucoside: resveratrol with a glucose molecule attached. It occurs naturally in grapes, red wine and Japanese knotweed, and it is the form of resveratrol found in some red grape supplements. Some grape-based products list only a few milligrams of piceid per capsule; M98 provides 450 mg of 98% Resveratrol PICEID per serving, verified by a public third-party Certificate of Analysis.
What is the difference between Resveratrol PICEID (Polydatin) and standard resveratrol?
Polydatin (Trans-Resveratrol-3-O-glucoside) is resveratrol with an attached glucose molecule. That glucose makes it up to 25x more water-soluble [10][11] and lets intestinal glucose transporters (SGLT1) take it up, while standard resveratrol relies on passive diffusion alone [2]. In animal studies, polydatin was the main form of resveratrol circulating in the blood after oral dosing [4].
Is Resveratrol PICEID (Polydatin) better absorbed than resveratrol?
Peer-reviewed papers describe polydatin as having higher intestinal absorption and improved bioavailability compared with resveratrol, due to its sugar group [15]. It is far more water-soluble [10] and uses an additional uptake route through the SGLT1 glucose transporter [2]. Standard resveratrol is absorbed but converted so quickly that only trace amounts of free resveratrol reach the blood [9].
Is polydatin better than micronized resveratrol?
They solve different problems. Micronization shrinks particle size so resveratrol disperses better. Polydatin changes the molecule itself: it is up to 25x more water-soluble [10][11] and adds a glucose-transporter uptake route that free resveratrol does not have [2]. That is why we consider M98 a step beyond super micronized resveratrol.
Does polydatin activate sirtuins, or only after it turns into resveratrol?
Both. In a rat study, polydatin itself increased SIRT1 enzyme activity and its effects disappeared when SIRT1 was blocked [14]. In human cells it restored mitochondrial SIRT3 activity [16]. Polydatin also converts to resveratrol in the body [3], which is a well-established SIRT1 activator [8].
How long does polydatin stay in circulation?
In rats, oral polydatin had a plasma half-life of roughly 3 to 4.5 hours [12], while free resveratrol is cleared within minutes in animal studies [13]. Polydatin was also the main form circulating in the blood after oral dosing of either compound [4]. Human pharmacokinetic studies of polydatin have not yet been published.
Why is polydatin less common than trans-resveratrol?
High-purity polydatin costs considerably more to produce than 99% trans-resveratrol, so most brands use the cheaper free form. M98 uses 98% Resveratrol PICEID (Polydatin) with no other ingredients, verified by a public third-party Certificate of Analysis.
Will the powder dissolve completely in liquids?
M98 Resveratrol Complete may not dissolve completely, and you may see particles in your beverage. This does not indicate a quality problem. Polydatin is far more water-soluble than standard resveratrol, but at 450 mg some particles can remain visible.
Can I combine M98 Resveratrol with other supplements?
Yes. M98 is commonly paired with NMN (NAD+ support for sirtuins), EGCG, curcumin, and senolytics as part of a healthy aging routine. Consult a healthcare provider before combining multiple supplements.
