Analysis

Chromium chloride is supplied at 400 mcg, but it is a less compelling form than common organic chromium complexes. The dose may support glucose metabolism, yet that does not establish meaningful weight loss by itself.

Trans-resveratrol is clearly identified from Polygonum cuspidatum, though 10 mg is a small amount and the capsule offers no stated absorption support. The 810 mg proprietary blend is the dominant part of the formula, but its ingredients and individual doses are unavailable.

The formula is therefore difficult to assess for appetite, thermogenesis, or sustained metabolic support. Its costly serving further weakens the case for choosing it over a transparent, goal-specific product.

Who is it for
  • Adults specifically seeking chromium-based metabolic support
  • Users whose clinician has reviewed the high chromium amount
  • People comfortable with a proprietary formula
Best for
  • Chromium supplementation
  • Limited carbohydrate-metabolism support
  • Short trial use with glucose monitoring when appropriate

Pros

  • Clearly discloses 400 mcg chromium
  • Identifies the trans form of resveratrol
  • Uses a simple capsule format

Cons

  • The main 810 mg blend is fully proprietary
  • Chromium chloride is a less compelling form
  • Resveratrol is limited to 10 mg
  • Serving value is weak

Warnings

  • Chromium may add to the glucose-lowering effects of insulin or diabetes medicines, increasing the chance of low blood sugar.
  • Polygonum-derived resveratrol may retain emodin when removal is not verified, which can cause loose stools or cramping.
  • The proprietary blend prevents a full interaction and tolerance review because its ingredients are not disclosed.

Nutrient quality

40 Lower impact

Trans-resveratrol is identified, while chromium chloride has weak absorption and the larger blend has no form detail, and chromium is substantial, but 10 mg resveratrol is minimal and the proprietary blend cannot be judged. The chromium amount is high for general use, while hidden blend contents prevent a complete safety assessment, while chromium and resveratrol have limited weight-management relevance, while the hidden blend prevents a strong fit assessment.

.

Ingredient transparency

41 Lower impact

Several core ingredients have amounts, but a proprietary blend hides important component doses, and a proprietary blend hides the amounts of its individual components. Serving count is supplied, but complete daily-use directions are not provided, while inactive ingredients and excipients are not included in the supplied label details.

.

Customer satisfaction

60 Moderate impact

The supplied average rating is weak, and moderate review volume provides a reasonable evidence base. Specific review themes are unavailable, so repeated negatives and real-world fit remain uncertain.

.

Value for money

27 Situational impact

Major dose or disclosure problems make the formula difficult to justify on quality alone, and the very high serving cost substantially weakens value. The proprietary blend prevents assessment of low-value additions, while dose, disclosure, or serving-value limitations make it less competitive than similar products.

Resveratrol · 10 mg

Chromium can support insulin action and carbohydrate metabolism, but most of the formula is hidden in a proprietary blend. The small resveratrol amount is unlikely to add meaningful mitochondrial support.

Breadth appears wide on the label, yet undisclosed ingredient amounts prevent a reliable potency assessment. Chromium chloride is a less compelling form than better-studied organic chromium complexes.

Report overview
Chromium (Chromium Chloride) · 400 mcg OverallScore42
F Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyD- Value

The chromium dose is substantial, but chromium chloride has poor absorption compared with organic forms. No trademarked chromium source is identified, and the label gives only one amount for the compound. The normalized cost is relatively high despite the formula containing additional blends.

Resveratrol (Polygonum cuspidatum (root) extract) · 10 mg OverallScore34
C Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyF Value

The trans isomer is explicitly disclosed, but its daily amount is too small to align well with the collection goal. A standard capsule provides no absorption enhancement, and the larger proprietary blend does not clarify resveratrol extract yield or purity. Polygonum cuspidatum root extract lacks emodin-removal verification, which may create mild laxative effects, while the low active amount also makes value poor.

Chromium Picolinate

Swanson
Branded chromium picolinate provides a more appropriate form and practical amount than the original high-dose chromium chloride. The focused formula is transparent, although direct effects on weight remain modest.
84 Performance

Resveratrol 250 mg with Red Wine Extract

Solgar
A meaningful trans-resveratrol amount in a fat-containing softgel provides far more antioxidant depth and better delivery potential than the original minimal dose. It omits chromium and may add bleeding risk with anticoagulant or antiplatelet medicines.
88 Performance

Optimized Chromium with Crominex 3+ 500 mcg

Life Extension
Branded Crominex chromium provides a clearly characterized form at a targeted amount without an opaque weight-management blend. It may support glucose handling but does not directly raise metabolic rate and can add to glucose-lowering medicines.
91 Budget

Albion Chelated Chromium 200 mcg

Swanson Ultra
A fully identified chromium chelate provides a practical metabolic-support amount at far lower recurring cost. The focused label is much easier to assess than the original proprietary blend, though chromium alone should not be expected to produce substantial weight loss.
86 Budget

Tri-Chromium 500 mcg

NOW
Multiple absorbable chromium sources plus cinnamon offer coherent glucose-metabolism support at lower recurring cost. The form-level amounts are somewhat ambiguous, but the formula is substantially more transparent than the original blend.
84 Budget

Chromemate Chromium GTF 200 mcg

Source Naturals
Chromium polynicotinate provides a well-absorbed form at a meaningful amount for much lower recurring cost. It omits the original resveratrol and hidden weight-management blend, while chromium alone has limited weight-loss depth.
89 Value

Chromium Picolinate 200 mcg

Best Naturals
Chromium picolinate provides a useful, clearly identified form at a highly economical serving cost. The simple formula lacks resveratrol but offers a much stronger transparency-to-cost balance than the original.
82 Value

Resveratrol 100 mg

Life Extension
Trans-resveratrol from grape and knotweed plus quercetin provides meaningful antioxidant coverage at low recurring cost. Duplicate source entries blur the total active amount, but the formula offers far more resveratrol depth than the original.
90 Value

Chelated Chromium 200 mcg

Carlson
Chromium nicotinate glycinate provides a favorable form at a practical amount with a long, economical supply. It is better suited to glucose handling than direct weight loss, but its quality-to-cost balance clearly exceeds the original opaque blend.
