Nutritionist Reveals Which Supplements to Avoid and Which Ones to Take: Ensuring Quality Through Trusted Lab Testing

In recent years, dietary supplements have become a cornerstone of maintaining health and wellness. However, as highlighted by a nutritionist’s expert reveal, not all supplements are created equal. Some products carry hidden risks including contamination, unnecessary additives, and questionable efficacy. Ensuring safety and efficacy starts with stringent third-party testing—enter Qalitex, an ISO 17025–accredited microbiology and analytical chemistry laboratory based in Irvine, California.

Which Supplements Should You Avoid?

The nutritionist advises consumers to be cautious with supplements that lack transparent ingredient lists or certification. Common pitfalls include:

• Supplements with unverified heavy metals, such as lead or mercury
• Products without Certificate of Analysis (CoA) indicating thorough testing
• Over-promising supplements lacking scientific validation
• Supplements prone to microbiological contamination

These issues can result in health risks rather than benefits. Therefore, relying on supplements that have undergone rigorous testing ensures safety and compliance.

Recommended Supplements and Why Quality Testing Matters

Quality supplements typically display clear lab certifications, standardized dosages, and compliance with regulatory bodies such as the FDA. As per the nutritionist’s guidance, consumers should prioritize:

• Supplements with validated ingredients consistent with labeled claims
• Products tested for heavy metals and microbial contaminants
• Brands engaging in shelf-life and stability studies to ensure potency until expiration

Achieving these assurances requires partnering with trusted laboratories like Qalitex, which provides comprehensive analytical services including analytical chemistry lab testing and microbiology testing services.
