HelloPharmacist Scorecard of Portion Control by Higher Nature

Four independent checks of what is known — a summary of the available information, not a grade of the product itself.

Evidence for Intended Use
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

None of the active ingredients could be matched to our evidence database, so intended use can't be graded.

Why this rating?
  • None of the active ingredients could be matched to a HelloPharmacist monograph, so intended use can't be graded against our evidence data.
Ingredient Transparency
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (600 mg) without saying how much of each component you get.
Known Interaction Concern
Not assessable

None of the active ingredients could be matched to our interaction database.

Why this rating?
  • We couldn't match any ingredient to a HelloPharmacist monograph, so there was nothing to check interactions against.
Safety Information
Unable to assess

None of the active ingredients could be matched to our safety data.

Why this rating?
  • We couldn't match any ingredient to a HelloPharmacist monograph, so there was no safety data to measure.

HelloPharmacist summaryFormula with limited ingredient disclosure with no assessable stated purpose. Medication interactions could not be assessed, and safety information could not be assessed.

Assessment coverage: 0 of 1 active ingredient matched to our full ingredient reviews (monographs). Based on the product label dated Jan 23, 2015.

This Scorecard evaluates available label information, ingredient evidence, and known medication-safety considerations. It does not independently verify product identity, purity, potency, contamination, or manufacturing quality. How these ratings are computed

Proprietary Blend2 drug types · 7 drugs

Succinylcholine

In humans, consuming potatoes prior to preoperative fasting prolongs the duration of the succinylcholine-induced neuromuscular block and slows recovery from anesthesia. This interaction is possibly related to inhibition of the butyrylcholinesterase enzyme by potato glycoalkaloids.

Likelihood Probable Evidence B
Thrombolytic Drugs

Theoretically, concomitant use of potato may enhance the effects of thrombolytic drugs. A carboxypeptidase inhibitor isolated from potato tubers may have inhibitory effects on thrombin-activatable thrombolysis inhibitor, and thereby enhance the activity of thrombolytic agents.
