Editorial score and research-dose calculations
These calculations describe our scoring method. They are not a recommended dose or proof of benefit from this product.
The ingredient was tested in an RCT at the same dose this product sells.

Vitamin C umbrella review 2022 (76 meta-analyses)(Vitamin C)An umbrella review of 76 meta-analyses found that higher vitamin C intake (50-100 mg/day increment) was associated with reduced all-cause mortality and cardiovascular disease risk. Studied at 100 mg. This product: 180 mg.
Vitamin C + telomere length 2023 (NHANES)(Vitamin C)In 7,094 NHANES participants, higher dietary vitamin C intake was significantly associated with longer telomere length after adjusting for age, sex, race, and BMI.
Vitamin C and CVD 2020 (Antioxidants)(Vitamin C)This review of clinical and preclinical studies summarizes evidence that vitamin C's antioxidant and endothelial-protective properties may benefit coronary heart disease, heart failure, and hypertension, while noting inconsistent trial results.
How we scored this productShow the full breakdown▾
Dose vs. studies (50%)iWhy 6.9 of 10. Primary ingredient is Vitamin C (evidence grade A). It delivers 180 mg, 90% of the studied range low edge (200 mg). Below what the trial used. Read the rule →6.9
Transparency (20%)iWhy 5.0 of 10. Earned points for all doses disclosed. Lost points for no public certificate of analysis and no independent third-party testing. Read the rule →5.0
Value (10%)iWhy 6.2 of 10. One day at the trial dose costs about $2.78. That is more expensive than average (229 of 313 by cost per effective day). Read the rule →6.2
Formulation (10%)iWhy 5.0 of 10. No published absorption advantage or disadvantage on file. The default of 5 is not a criticism. Read the rule →5.0
Default. No absorption data on file.
Safety (5%)iWhy 5.0 of 10. Baseline 5.0. Third-party testing adds 2.0. Public lab certificate adds 1.5. NSF, USP or Informed Choice certification adds 1.5. Active safety signal subtracts 3.0. Read the rule →5.0
Community sentiment (5%)iWhy 3.7 of 10. No external reviews found, so community sentiment defaults to neutral. Community never counts as clinical evidence. Read the rule →3.7

Evidence gates dose: the evidence grade sets the ceiling, and the dose decides how much of that ceiling the product reaches. Value = inverse of price-per-trial-dose-day. Community = mean sentiment of external reviews. Safety caps applied after weighting.
This score is our editorial judgment, not a scientific standard. We combine published evidence, dose, price, transparency, and consumer signals into one composite: this is our method, not a peer-reviewed clinical rating. A higher score means a product does better on the factors we weight, not that it is medically proven to work.
This Vital Proteins Vital Proteins Beauty Boost Capsules scores 6.0, making it below the site average. It delivers 0mg of Selenium, inside the studied range of 0–0mg with grade A evidence (strong human trial data). The quality transparency (5.0) is limited by the lack of third-party testing. At $2.78/day it's among the more expensive options in Vitamin.
What drives the score up
Dose-evidence score of 6.9 shows decent alignment with trial doses.
Selenium is dosed at the full research level with grade A evidence (strong human trial data).
Vitamin C has grade A evidence and is dosed at 90% of the trial dose.
Vitamin C adds grade A evidence at 90% of the trial dose.
What drags it down
Vitamin C (180.0mg is 36% of the 500mg trial dose) is significantly under-dosed.
NR (5.0mg is 2% of the 300mg trial dose) is significantly under-dosed.
Vitamin B6 (P-5-P) (3.3mg is 16% of the 20mg trial dose) is significantly under-dosed.
No third-party testing, which caps the quality transparency.
Quality transparency of 5.0 is below the site average.
Why you'd choose it
You want Selenium from a Vital Proteins product.
Why you might skip it
You want third-party verified purity.
You want a product with a publicly available CoA.
You need a full trial dose of vitamin c (this product under-doses it).
Question 1
Does the molecule work?
The science behind each active ingredient, independent of which brand sells it.
Every active in this formula, its declared dose per serving, the dose used in the primary human trial, how much of that trial dose this product delivers, and the evidence grade for the ingredient itself.
Percentages are dose per serving ÷ primary trial dose. Below 50% means the formula is unlikely to reproduce the trial outcome for that active. Grade A = multiple large human RCTs. Grade F = no human evidence. How grades work. Full glossary →

Editorial notes
A standard high-dose B-vitamin/antioxidant multivitamin marketed for beauty, not a collagen product itself, doses are generous multiples of DV (biotin 500% DV) with no clinical trial on the finished blend; unremarkable versus any generic hair/skin/nail multivitamin.
