How to Understand Supplement Labels: What to Check Before You Buy

 

If you’ve ever stared at a supplement label and felt confused, you’re not alone. With so many vitamins, minerals, blends, and scientific claims printed on a bottle, choosing the right product often feels overwhelming. But understanding supplement labels is one of the best ways to know exactly what you’re putting into your body and whether it’s worth your money.

At Buy Nutritionals, we believe clarity helps you make smarter, healthier choices. Whether you’re shopping for USANA CellSentials™, BiOmega™, Vitamin D, Probiotics, or any of our most trusted essentials, knowing how to read the label ensures you get quality, potency, and total transparency.

Here’s what to look for before hitting “add to cart.”

1. Start With the Supplement Facts Panel

This is the most important section of the label. It tells you:

• Serving size
• Amount per serving
• Percent Daily Value (%DV)
• Active ingredients

The serving size matters because all nutrient amounts are based on it. For example, if one serving is two tablets but you only take one, you’re only getting half the listed nutrients.

The %DV helps you understand how much of each nutrient contributes to your daily needs. Anything between 10–20% DV is moderate; above 20% is considered high.

2. Scan the Ingredient List Carefully

The ingredients list tells you what’s actually inside. High-quality supplements are transparent and avoid unnecessary fillers.

Look for:

• Active ingredients first (vitamins, minerals, antioxidants, omega-3s, probiotics, etc.)
• Minimal additives
• No artificial colors or preservatives
• No cheap fillers like talc, hydrogenated oils, or artificial sweeteners

USANA supplements are known for clean, science-backed formulations without harmful fillers. Their hybrid tablet technology and InCelligence ™ formulas are designed for superior absorption and bioavailability.

3. Check for Third-Party Testing or Certifications

This is one area where quality really matters. Supplements can differ widely in purity, potency, and safety, so always choose brands that undergo third-party testing. Trusted labels include:

• NSF International
• ConsumerLab
• USP (U.S. Pharmacopeia)
• Athlete-approved certifications

For example, USANA MagneCal D^TM has earned the ConsumerLab Seal of Approval, proving its purity and potency.

At Buy Nutritionals, every product is shipped directly from USANA, giving you 100% authenticity and 100% potency guarantee.

 

4. Look for the Expiration or “Best By” Date

Supplements don’t work if they’ve expired, especially probiotics, vitamins, and omega-3s. Always check the date printed on the label.

We proudly offer the latest expiration dates on all products, so you always receive supplements at peak potency.

5. Understand Proprietary Blends

Many supplements list “proprietary blends” without breaking down the exact amounts of each ingredient. That makes it harder to know what you’re actually getting.

USANA does not hide behind vague blends. They disclose ingredients clearly and formulate based on clinical research.

 

6. Check Allergen and Sensitivity Warnings

Before you buy, look for notes such as:

• Gluten-free
• Dairy-free
• Soy-free
• Shellfish-free
• Non-GMO

Many USANA products meet strict allergen standards, which makes them ideal for sensitive individuals or health-conscious families.

7. Look Beyond the Label: Who Makes the Product?

A supplement is only as good as the science behind it. This is where USANA stands out:

• PhD-led research team
• Exclusive technologies (InCelligence ™, Poly C®, Hybrid technology, Olivol®)
• GMP-certified manufacturing
• 40+ quality tests per product
• Global reputation for purity, safety, and potency

8. Buy From Trusted, Authorized Sellers

Not all online sellers are reliable. Counterfeit and expired supplements are common on marketplaces. Buying from Buy Nutritionals (Approved Authorized Distributor (ADV-154)) gives you:

• Shipping within 2–3 days
• Free shipping over $100
• Products shipped directly from USANA
• 100% money-back guarantee

Your health deserves nothing less.
