#2 of 9 · Highest Dose + Absorption✓ Label verified · Supplement Facts read Sep 7, 2026Real retailer photo, cut out. Label unedited.
Buy it. Dose and absorption in one bottle. The heaviest silymarin load in the set, paired with a Siliphos phytosome fraction and NSF-registered manufacturing.

Why It Scores 8.4 — And The Label Line Behind Each Number
Form & Bioavailability
30% of scoreA hybrid: high-dose standardized extract plus a 160 mg Siliphos silybin-phytosome fraction. You get the absorption hedge of a phytosome layered onto a genuinely large silymarin load — close to the top of the category on form.
- Form
- Standardized extract + Siliphos silybin-phospholipid (softgel)
Silymarin/Silybin Dose vs Clinical Range
25% of scoreAt ~480 mg silymarin / ~180 mg silybin per 2-softgel serving, this is the highest disclosed load in the set and lands squarely in the range used in clinical trials — the best score on this axis.
Third-Party Testing & Quality Assurance
20% of scoreNSF-registered GMP facility with a Certificate of Analysis available. Strong, well-documented QC — a notch below Thorne's certification reputation but clearly above the budget field.
- Testing
- NSF-registered GMP facility; CoA available
Value per Effective Serving
15% of scoreThe priciest-per-serving of the standardized options, and a two-softgel serving. The dose and dual-delivery justify it, but on pure cost-per-serving it trails the value picks.
- Supply
- 120 softgels = 60 servings
- Price
- ~$32 (~$0.53/serving)
Formulation Suitability & Tolerability
10% of scoreThe softgel and phospholipid contain soy, which rules it out for soy-avoiders. Otherwise well tolerated, but the allergen profile is the weak point that keeps it off the #1 spot.

Marketing Claims Vs. Reality
Provides ~480 mg silymarin / ~180 mg silybin per serving
The label discloses the standardized silymarin and silybin content per 2-softgel serving, and standardization to specific silybin isomers backs the number.
Up to 3× better absorption
The Siliphos fraction does raise silybin absorption in principle, but the specific '3×' multiplier is a manufacturer claim without a cited independent head-to-head against this exact formula.
Standardized to silibinins and isosilybin A & B
The label specifies standardization to defined silybin isomers rather than only total silymarin, which is a genuine formulation strength.
Supports healthy liver function
Dose is in the trial range, but high-quality RCTs and meta-analyses (Rambaldi 2005; Wah Kheong 2017) did not confirm a clinical benefit, so the functional claim is only partially supported.
What Our Test Actually Found
One serving hits the trial range
Several liver studies dosed around 420 mg/day of silymarin; this serving clears that at ~480 mg without asking you to count out four capsules. On the 25%-weighted dose axis it's the class leader.
The phytosome is a hedge, not the whole formula
Only 160 mg of the load is the Siliphos phytosome; the rest is standardized extract. You get an absorption boost on part of the dose — useful, but don't read it as a fully phospholipid-complexed product like Thorne.
Soy is the real disqualifier
The softgel and phospholipid contain soy. That single fact, plus the highest per-serving price of the standardized options, is why a formula that beats #1 on dose still lands at #2.
The 3× number is the brand's
Absorption enhancement from Siliphos is real, but the exact multiplier comes from the manufacturer. Treat it as directional, not a verified head-to-head result.
Full analysis: all pros & cons (7), buy if / skip if
- Highest disclosed silymarin load in the set — right in the clinical range per serving
- Adds a Siliphos phytosome fraction on top of high-dose standardized extract
- Standardized to specific silybin isomers, not just total silymarin
- NSF-registered manufacturing with a Certificate of Analysis
- Contains soy (softgel/phospholipid) — off-limits for soy-avoiders
- Two-softgel serving and the priciest-per-serving standardized option
- 'Up to 3× absorption' is a brand claim, not an independent head-to-head
- You want a clinical-range dose in a single serving
- You value both high dose and a phytosome absorption boost
- You want NSF-registered manufacturing with a CoA
- You avoid soy
- You want the lowest cost per serving
The heaviest silymarin load in the set, paired with a Siliphos phytosome fraction and NSF-registered manufacturing. It loses the top spot only on two real points: it contains soy, and it's the priciest per serving of the standardized options. For a soy-tolerant buyer, it's the strongest formulation on the page.
If your goal is to hit a trial-level silymarin dose without swallowing four capsules, this is the formula. One two-softgel serving delivers roughly 480 mg of standardized silymarin (~180 mg silybin) and stacks a 160 mg Siliphos phytosome fraction on top, so you get both dose and an absorption hedge in the same serving. The catches are soy content and top-of-set per-serving price.
The strongest formulation — soy and price aside
This is the pick if your goal is to hit a trial-level silymarin dose without counting out four capsules — one serving does it, and the Siliphos fraction hedges the absorption problem. The catches are real: it contains soy, it costs the most per serving of the standardized options, and the absorption multiplier is the brand's own number. For a soy-tolerant buyer who wants dose and bioavailability in one bottle, it's the strongest formulation on the page — it loses the top spot only on soy and price.
If This Doesn’t Fit — Try These
01Thorne Milk Thistle Phytosome
If you want the form the bioavailability science actually points to, from the brand with the strongest quality reputation in this list, this is it.
06Solaray Milk Thistle 350 mg
The easiest one-and-done pick — a single vegan capsule delivers the most silymarin per cap of any plain extract here, with a guaranteed-potency label.
04Nutricost Milk Thistle 300 mg
This is the value winner and the sane default for most people — a legitimate 80% extract at a price that makes daily use painless.
Quick Answers
How much silymarin do I get per day?
One serving is two softgels providing roughly 480 mg of standardized silymarin (~180 mg silybin), plus a 160 mg Siliphos phytosome fraction — the highest disclosed load in this lineup.
Does it contain soy?
Yes. The softgel and phospholipid components contain soy, so it isn't suitable if you avoid soy — consider the soy-free Thorne phytosome instead.
Is the '3× absorption' claim reliable?
Treat it as directional. The Siliphos fraction genuinely improves silybin absorption, but the specific 3× figure is the manufacturer's and isn't backed by a cited independent head-to-head.
