Thyroid Support Complex may help fill nutrient gaps relevant to normal energy and hormone functions. Its ashwagandha preparation is not clearly matched to those behind stress-related findings, making those effects uncertain.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality38

Most ingredient forms are named, but their quality remains uncertain. The tyrosine form is not specified, adding a further gap in comparison.

Ingredient Transparency77

All amounts and most forms are listed, helping you compare the named ingredients. The tyrosine form and split between the vitamin D declarations are not specified.

Value For Money36

The tyrosine contribution offers limited value at the full serving cost. The value of the other ingredients remains uncertain.

Customer Satisfaction72

Customer ratings are very positive. The smaller review base limits confidence in how widely that satisfaction is shared.

Product Focus53

The formula spans stress, energy and several other purposes, but many benefits depend on nutritional need or a particular extract. The ashwagandha preparation does not clearly match the extracts behind the stress and cognitive findings.

Vitamin D · 5 mcgAshwagandha · 400 mgVitamin C · 150 mg

Ashwagandha has direct perceived-stress findings, but this declaration does not match the preparations retained as studied here. Tyrosine’s situational role concerns cognition under intense demands rather than calmness. Zinc has conditional nutritional-status and clinical-anxiety support rather than a broad stress-relief effect. The small vitamin C and vitamin D amounts make no contribution in the saved findings.

How this product is rated for Stress Relief

Ingredient fit61

Ashwagandha provide the main stress-related focus, with the serving amounts determining their contribution.
Goal fit
Stress-related ingredients sit within a broader formula, reducing its focus on this goal.
Dose adequacy
The serving supplies partial or uneven comparison amounts, limiting the strength of its contribution.

Pathways88

The strongest retained area is stress-hormone regulation. Other areas have uneven or limited coverage.
Depth
The strongest retained area is stress-hormone regulation. This describes ingredient roles rather than proven relief.
Breadth
The main retained areas are stress-hormone regulation, neuroinflammation and resilience, sleep recovery.

Evidence67

Ashwagandha has direct perceived-stress findings, with applicability dependent on extract, outcomes and duration.
Evidence strength
Ashwagandha has direct perceived-stress findings, with applicability dependent on extract, outcomes and duration.
Studied preparation
The preparation match is incomplete for Ashwagandha. This limits direct transfer of the findings.

Formulation logic100

The retained ingredients have their specified partner support, and no configured conflict was identified.
Partner coverage

Vitamin D · 5 mcgAshwagandha · 400 mg

Ashwagandha may help with stress-related emotional strain. The extract preparation matters: an unspecified extract can't be assumed equivalent to KSM-66, so the size of any mood benefit is uncertain. Its relevance is to feeling less stressed, rather than treating depression or improving everyone's mood.

How this product is rated for Mood Support

Ingredient fit58

Ashwagandha, L-Tyrosine, Vitamin D give the main mood-related ingredient connections.
Goal fit
Ashwagandha, L-Tyrosine, Vitamin D connect with mood-related functions.
Dose adequacy
Zinc 20 mg, L-Tyrosine 500 mg, Vitamin D 5 mcg; other declared nutrients vary in amount.

Pathways16

The ingredients relate most directly to neuroinflammation and neuroplasticity. This describes their roles, not a promise of a particular emotional effect.
Depth
The closest ingredient connection is neuroinflammation and neuroplasticity.
Breadth
Different biological roles do not guarantee broader or stronger mood benefits.

Evidence48

The ashwagandha preparation is unidentified, limiting how confidently benefits from a named extract apply.
Evidence strength
The ashwagandha preparation is unidentified, limiting how confidently benefits from a named extract apply.

Iodine · 150 mcgVitamin D · 5 mcg

Vitamin C can help address fatigue caused by low vitamin C intake. Iodine supports thyroid-hormone production, but deficiency correction is a separate application from routine energy enhancement. Ashwagandha's supplied stress trial did not establish a clear standard fatigue benefit, and tyrosine's cold-stress findings concern working memory rather than everyday vitality. Vitamin D is present below the saved comparison's inclusion threshold.

How this product is rated for Energy

Ingredient fit63

The relevant ingredients provide a mixed connection to energy. Their declared amounts only partly meet the saved amount references.
Goal fit
The saved energy fit is diluted by broader product aims or ingredients outside the credited energy roles.
Dose adequacy
Several amounts provide partial contributions against the saved references rather than full amount coverage.

Pathways49

The strongest saved connection is stress-fatigue resistance. Only this pathway reached the breadth threshold.
Depth
The strongest saved connection is stress-fatigue resistance.
Breadth
Only the strongest pathway meets the saved breadth threshold; the other assessed pathways do not.

Evidence64

Ashwagandha provides the leading evidence contribution in the saved findings. Some included ingredients lack a matching studied preparation, limiting transfer of those findings.
Evidence strength
Ashwagandha supplies the leading evidence contribution; its specific population and outcome limitations still apply.
Studied preparation
The preparation check is partial; Iodine, Tyrosine lack a matching studied preparation.

The included ingredients have no missing required partners, and no configured conflict was matched. Each included amount clears the saved minimum comparison threshold.
Partner coverage
No required partner is missing from the included contributions.
Conflicts
No configured ingredient conflict was matched; this is not a comprehensive safety assessment.

Zinc · 20 mgVitamin D · 5 mcgAshwagandha · 400 mg

Zinc may help restore testosterone when low zinc is contributing to low levels. That benefit depends on a shortage; taking extra zinc doesn't imply a further increase when you already get enough. Zinc supplies a nutrient involved in normal hormone function, so its connection to this goal is primarily about correcting low intake.

How this product is rated for Testosterone Support

Ingredient fit59

Zinc has a conditional connection through correction of low zinc. The serving contains Zinc, Selenium, Vitamin D, Ashwagandha.
Goal fit
Zinc is most relevant when low zinc affects testosterone.
Dose adequacy
Zinc 20 mg; Selenium 200 mcg; Vitamin D 5 mcg; Ashwagandha 400 mg. These are label-serving amounts, not an assumed daily intake.

Pathways18

Zinc primarily relates to nutrient sufficiency rather than a direct hormone-boosting effect.
Depth
Zinc primarily relates to nutrient sufficiency rather than a direct hormone-boosting effect.
Breadth
The ingredients do not imply broad effects across testosterone production and regulation.

Evidence84

Zinc may help when deficiency lowers testosterone, rather than increase it above adequate levels.
Evidence strength
Zinc has a conditional connection through correction of low zinc.
Studied preparation
The ashwagandha preparation is unresolved, so benefits tied to particular extracts may not transfer.

Zinc · 20 mg

Ashwagandha has limited, short-term cognitive findings for a specific root-and-leaf extract; these do not establish sustained productivity or transfer directly to this declared preparation.

How this product is rated for Productivity Boost

Ingredient fit54

The saved findings count Ashwagandha, L-Tyrosine, Zinc. Ingredient amounts and the presence of other actives determine how focused the formula appears.
Goal fit
The formula includes ingredients counted for this goal alongside other active ingredients, so its focus is broader than productivity.
Dose adequacy
The counted amounts receive partial recognition overall; this describes the saved amount comparison rather than a proven productivity dose.

Pathways63

The saved pathway coverage describes how the counted ingredients are assigned to attention, memory, energy or stress-related mechanisms, without establishing improved work output.
Depth
The strongest recorded pathway is synaptic plasticity and neuroprotection, reflecting the saved ingredient assignments rather than proof of improved work performance.
Breadth
Two pathways reach the comparison threshold, indicating broader coverage of the selected mechanisms.

Evidence88

The saved evidence findings recognize ingredient amounts and preparations, while the scientific limits depend on the specific ingredient, preparation and population.
Evidence strength
Zinc leads the saved evidence comparison, but its contribution remains subject to the preparation and population limits described for that ingredient.
Studied preparation
The saved findings do not recognize studied preparations for L-Tyrosine; the other counted preparations are recognized.

Formulation logic100

The counted ingredients meet the saved amount thresholds and partner requirements. No configured conflict is recorded.
Partner coverage
The counted ingredients either stand alone in the saved findings or have their required partner present.
Conflicts
No configured ingredient conflict was matched.
Effective doses
All counted ingredients meet the minimum amount threshold used for comparison; that threshold is not proof of a clinically effective productivity dose.
