Benefits & Description
Nature's Lab Perfect Iron helps improve iron levels to support healthy energy and red blood cell health.* This formula utilizes iron as bisglycinate chelate, a form of iron that is gentle on the stomach and more bioavailable than other types of iron.*
Key Benefits:
- Supports healthy red blood cells*
- Supports energy regulation*
- Gentle, non-constipating formula*
- Formulated with iron bisglycinate, a highly bioavailable form of iron*
The Benefits of Iron
Iron is required in larger amounts for certain individuals including vegetarians, menstruating or pregnant women, athletes, individuals with poor gastrointestinal health and those taking certain medications.* Approximately 10 million Americans are iron deficient due to poor iron absorption, low iron diets and other conditions.* Nature’s Lab Perfect Iron utilizes iron bisglycinate chelate for optimal absorption.* This form of iron is bound to the amino acid glycine and is absorbed more efficiently than other forms of iron (such as ferrous sulfate).* This also results in an iron supplement that is non-constipating and gentle on the digestive system.*
Suggested Use
As a dietary supplement, take 1 capsule one time daily, preferably with a meal, or as directed by a qualified healthcare practitioner.
Warnings: Pregnant or lactating women and people with known medical conditions and/or taking drugs should consult with a qualified healthcare practitioner prior to taking dietary supplements. Discontinue use and consult your doctor if any adverse reactions occur.

Six-dimension breakdown
Why this scored 65/100
Iron bisglycinate chelate at 25 mg is a preferred low-GI form for repletion (Milman 2014 showed bisglycinate at 25 mg matched ferrous sulfate 50 mg with fewer GI effects). Well-chosen form and reasonable maintenance dose. Approaches Verified but lacks third-party assay disclosure.
Evidence & sources
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

- 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
- 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
- 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
- 0–19: No credible evidence base or unverifiable claims.
