SUPPLEMENT DECISION FRAMEWORK
A Simple Way to Understand What You Actually Need
Researched and organized by Joshua Roiland, BS, CSCS, FNS
INTRODUCTION
Supplements are not one category—they are different tools with different levels of evidence, regulation, and purpose.
Most confusion comes from skipping the most important step:
Understanding what type of supplement you are actually looking at before deciding if you need it.
This guide breaks supplements into four clear categories so you can make safer, more informed decisions.
HOW TO USE THIS
Do not start by picking a product.
Start by identifying the category that matches your goal:
Evidence-based foundation (Kreider), (VanDusseldorp), (Park)
Clinical / deficiency correction (Amjera)
Organic / wellness-focused (USDA)
Performance blends (Saldanha), (Vibrant Health)
Each category answers a different type of question.
1. FOUNDATIONAL EVIDENCE-BASED SUPPLEMENTS
WHAT THIS IS
These are simple-ingredient (sometimes single-ingredient) supplements with the strongest scientific support and most consistent results across populations.
Examples:
WHY IT MATTERS
These are the baseline tools of supplementation.
They are:
heavily researched (Kreider), (VanDusseldorp), (Park)
consistent across brands
not dependent on marketing or formulation tricks
KEY IDEA
If you are unsure where to start, this category is the reference point for everything else.
There will be a future article for MY personal experience with Foundational Evidence based supplements
2. CLINICAL / MEDICAL-GRADE SUPPLEMENTS
WHAT THIS IS
Supplements used to correct or address identified deficiencies or clinical needs, often guided by bloodwork or healthcare professionals. There are even resources that can help determine if your current medications are possibly causing problems due to interactions in your body! You may actually benefit from STOPPING a supplement that is inappropriate for your current health, and medical status (as I have in the past. Drug interactions with supplements are not fun)
Examples:
KEY IDEA
These are not performance supplements.
They are corrective tools used when the body shows a specific need. (Amjera)
There will be a future article with MY personal experience with Clinical/ Medical Grade supplements
3. ORGANIC / WELLNESS SUPPLEMENTS
WHAT THIS IS
Supplements focused on sourcing, farming standards, and reduced synthetic processing.
Often certified organic or “clean label.”
KEY IDEA
Organic standards regulate how ingredients are produced, not how effective they are for performance.(USDA)
These are best for:

These may be best for this type of person: sourcing-conscious consumers
4. PROPRIETARY BLEND / PERFORMANCE SUPPLEMENTS
WHAT THIS IS
Multi-ingredient formulas where ingredients are listed, but exact dosages are partially hidden.
Common in:
KEY IDEA
Quality varies widely.
Some are highly engineered, others are underdosed marketing products.(Saldanha), (Vibrant Health)
The difference comes down to:
company credibility
testing standards
dosing transparency
manufacturing quality (cGMP, third-party testing)

SIMPLE DECISION RULE
Instead of asking:
“What supplement should I take?”
Ask in order:
Do I need foundational support first? (evidence-based) (Kreider) (VanDusseldorp) (Park)
Do I have a clinical deficiency? (Amjera)
Do I care most about sourcing and wellness? (USDA)
Am I choosing a performance blend knowingly? (Vibrant Health), (Saldanha)
IMPORTANT CONTEXT
All supplements should be viewed through the lens of:
training consistency for goals (Total Package (Men, Women), Individual goals, Fat loss, Strength)
Supplements support physiology—they do not replace it.
