Analysis

The formula pairs 200 mg of pure trans-resveratrol with 180 mcg of vitamin K2 as MK-7, creating a clear cardiovascular and antioxidant focus. A 2.5-gram hydrolyzed collagen serving adds connective-tissue support and reaches a useful beauty-oriented amount.

Ingredient forms and amounts are easy to assess, particularly for resveratrol and K2. Collagen quality is less transparent because its animal source, type, amino acid profile, and any standardization are not provided, and the dry tablet format offers no stated absorption support for the fat-soluble K2.

Six tablets per serving may be inconvenient for daily use, but the actives are more focused and transparent than many broad blends. The strongest fit is for adults seeking targeted cardiovascular support who can safely use vitamin K2 and resveratrol alongside their medications.

Who is it for
  • Adults seeking combined resveratrol and vitamin K2 support
  • People interested in cardiovascular and connective-tissue support
  • Users comfortable taking six tablets per serving
Best for
  • Cardiovascular support
  • Trans-resveratrol supplementation
  • A combined collagen and K2 routine

Pros

  • Uses clearly identified pure trans-resveratrol
  • Provides vitamin K2 in the MK-7 form
  • Discloses meaningful amounts for all three actives
  • Keeps the formula focused without an opaque proprietary blend

Cons

  • Requires six tablets per serving
  • Collagen source and type are not stated
  • No advanced resveratrol delivery feature is identified
  • No guidance is supplied about taking K2 with a fat-containing meal

Warnings

  • Vitamin K2 can counter vitamin K antagonist medicines such as warfarin; use requires clinician-guided consistency.
  • Resveratrol may add to bleeding risk when combined with anticoagulant or antiplatelet medicines.
  • The collagen animal source is undisclosed, so people with dietary or source-specific restrictions cannot verify suitability.

Nutrient quality

89 Highest impact

Pure trans-resveratrol, MK-7, and hydrolyzed collagen are credible forms supplied at useful amounts. Collagen lacks source and type details, and its role is less direct in a heart-focused formula.

Ingredient transparency

84 Highest impact

Every active ingredient has a specific amount and no proprietary blend obscures the formula. Missing collagen source details, non-active ingredients, and fuller use directions leave avoidable gaps.

Customer satisfaction

67 High impact

The average rating is strong and the review count gives it reasonable support. No review excerpts or complaint patterns are supplied to assess recurring problems or purpose-specific experiences.

Value for money

76 High impact

Three purposeful actives in useful forms give the formula reasonable substance. The six-tablet serving and incomplete collagen sourcing limit convenience and keep value from standing out.

The formula combines structural support, antioxidant signaling, and healthy calcium handling. It provides 2.5 g of collagen, 200 mg of pure trans-resveratrol, and 180 mcg of MK-7 vitamin K2 for the stated purpose.

Collagen is below stronger daily skin amounts and long-term resveratrol outcomes remain uncertain. Vitamin K2 can reduce warfarin’s effect, while resveratrol may add to bleeding tendency with anticoagulant medicines.

Collagen and MK-7 address the bone protein matrix and mineral placement, while resveratrol adds antioxidant support. The combination is relevant, although evidence for resveratrol as a bone active is less established.

The collagen amount is meaningful but below common higher-dose structural servings, while MK-7 is well supplied. Vitamin K2 can oppose warfarin and other vitamin K antagonist anticoagulants, making this a specific medication interaction.

Trans-resveratrol and MK-7 vitamin K2 support endothelial signaling, antioxidant defense, and calcium handling. Collagen contributes structural protein but has less direct cardiovascular relevance.

The resveratrol and K2 amounts are substantial and their forms are clearly identified. K2 opposes warfarin, while resveratrol may add to bleeding tendency with anticoagulant or antiplatelet medicines.

MK-7 and trans-resveratrol support arterial calcium handling and endothelial antioxidant pathways. The evidence is stronger for K2 biology than for hard cardiovascular outcomes from resveratrol.

Both heart-relevant actives are meaningfully dosed and clearly identified, while collagen is mainly structural support outside this goal. MK-7 can counter vitamin K antagonist medicines such as warfarin, making this formula unsuitable with that drug class unless specifically managed.

Trans-resveratrol provides antioxidant and cellular-signaling support, while hydrolyzed collagen may support connective tissue. Human inflammatory evidence is moderate and more relevant to markers than broad symptom relief.

Both main actives are supplied at meaningful supportive amounts. The six-tablet serving and lack of advanced resveratrol delivery reduce practicality.

Report overview
C+ Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyF Value

MK-7 provides the preferred vitamin K form, though its generic source is not branded or all-trans verified. The dry tablet lacks stated fat-meal guidance, limiting absorption support. The MK-7 amount is well aligned with the clinical target range; the high serving cost and generic source limit value.

C+ Active Ingredient Quality & BioavailabilityC+ Dose, Safety & Label TransparencyD- Value

Pure trans-resveratrol is clearly identified at a supportive 200 mg dose. Six pressed tablets are required and provide no advanced delivery support, though the non-knotweed presentation avoids the specific emodin concern. Cost efficiency is moderate, with the substantial collagen dose supplying separate value.

Collagen · 2500 mg OverallScore40
D+ Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyF Value

Hydrolyzed collagen supports absorption, and the 2,500 mg amount reaches the skin-focused dose range. Animal origin, collagen type, branded standardization, protein matching, and an amino acid profile are not disclosed. The cost per gram sits just inside the weak-value tier.
