Vital Functional Medicine is now selling pharmacy grade supplements! What’s the hype??
The difference between a retail supplement and a professional or "pharmacy-grade" supplement comes down to three key factors: purity, potency, and absorption.
1. Quality Control and Third-Party Testing
The biggest difference lies in oversight. The FDA regulates supplements more like food than drugs, meaning they don't have to approve them before they hit the shelves.
* Retail/Store Brands: These often rely on self-regulation. Studies frequently find that what is on the label doesn't match what is in the bottle. They can contain things like hidden allergens, heavy metals, or other unknown substances. You don’t *actually* know what’s in a supplement if it’s NOT pharmacy grade. ��
* Professional/Pharmacy-Grade: These brands are almost always required to adhere to Good Manufacturing Practices (GMP) and undergo third-party testing. This testing verifies three things:��
* Purity: Guaranteed to be free of contaminants like lead, mercury, and microbial growth.
* Potency: Guaranteed that the dose listed on the label is actually the amount contained in the pill.
2. Bioavailability and Formulation
A high-quality ingredient doesn't matter if your body can't use it. Professional supplements use superior, bioavailable forms of nutrients.
* Retail/Store Brands: Often use the cheapest, least active forms of a nutrient (e.g., magnesium oxide or synthetic folic acid). These forms are difficult for the body to absorb and can pass through your system without being utilized.
* Professional/Pharmacy-Grade: They use forms your body is designed to absorb, such as:
* Chelated Minerals (like magnesium glycinate) which are bonded to an amino acid for easy absorption.��
* Methylated Vitamins (like L-methylfolate), which are already in the active form, making them usable even for people with common genetic variations (like MTHFR) that struggle to convert standard vitamins.��
3. Exclusion of Fillers and Additives
Pharmacy-grade supplements focus on the active ingredient, not manufacturing cost.
* Retail/Store Brands: Often contain cheap fillers, synthetic dyes, artificial colors, and unnecessary binding agents (like titanium dioxide or hydrogenated oils) to make the pills cheaper to produce and last longer on the shelf.�
* Professional/Pharmacy-Grade: These supplements prioritize clean formulations, minimizing or eliminating unnecessary binders, fillers, and allergens, which is crucial for individuals with sensitivities or chronic health conditions.
