How To Read Supplement Labels Like an Informed Consumer
Insider guidance from a 34-year supplement veteran
Bruce Brightman
Founder, LifeSource Vitamins • Since 1992
Most people spend only a few seconds reading a supplement label before buying. That’s understandable — but it can lead to disappointment and wasted money. Learning how to read labels properly is one of the most valuable skills you can develop as a consumer.
After more than 34 years in the supplement industry, I’ve seen how labels can be written to sound impressive while hiding important details. Here’s what I wish more consumers knew.
- Serving Size — Is the recommended dose realistic?*
- Amount of Each Ingredient — Are the dosages clinically meaningful?*
- Proprietary Blends — Do they hide exact amounts?*
- Form of Ingredients — Are they high-quality, bioavailable versions?*
The Most Important Things to Check on a Label
• Serving Size — Is the recommended dose realistic?
• Amount of Each Ingredient — Are the dosages clinically meaningful?
• Proprietary Blends — Do they hide exact amounts?
• Form of Ingredients — Are they high-quality, bioavailable versions?
• Other Ingredients — Any unnecessary fillers or allergens?*
Common Red Flags on Supplement Labels
• “Proprietary Blend” with no individual dosages listed
• Very low dosages of key active ingredients
• Long lists of “other ingredients” with artificial colors or fillers
• Vague health claims that sound too good to be true
• No mention of third-party testing*

Safety & Considerations
Always consult with your healthcare provider before starting any new supplement regimen, especially if you are pregnant, nursing, taking medication, or have a medical condition.
Frequently Asked Questions
Q: What does “proprietary blend” mean?
A: It means the manufacturer doesn’t have to list the exact amount of each ingredient — only the total weight of the blend.*
