Caffeine Hidden in Orchid Supplements: What You Need to Know

study PMID: 40679500

Quick Summary: A recent study found that many sports supplements claiming to contain orchid extracts actually contained hidden caffeine. This means you might be getting a dose of caffeine without even realizing it!

Is Your Supplement Hiding Caffeine?

This study looked at 25 sports supplements that claimed to have orchid extracts. The shocking news? 64% of them also contained caffeine, even though it wasn't listed on the label! This is a big deal because caffeine can affect your performance and health.

Study Details

Who was studied: 25 sports supplements from 12 different countries.

How long: The study was conducted over 6 months.

What they took: Researchers analyzed the supplements to see if they contained caffeine and measured how much. The amount of caffeine varied greatly, from a tiny amount to almost as much as a strong cup of coffee!

What This Means For You

You might be getting more caffeine than you think: If you take supplements with orchid extracts, you could be unknowingly consuming caffeine.

Athletes beware: Caffeine can be a banned substance in some sports. Unlabeled caffeine could lead to a failed drug test.

Watch out for side effects: Caffeine can cause jitters, anxiety, and trouble sleeping. If you're sensitive to caffeine, this could be a problem.

Choose wisely: Look for supplements that are third-party tested and certified (like NSF or Informed-Choice). This means an independent organization has checked the product to make sure it contains what the label says and doesn't have hidden ingredients.

Study Limitations

Small sample size: The study only looked at 25 products, so it might not represent all supplements on the market.

Only tested for caffeine: Researchers didn't check for other hidden ingredients.

Didn't study people: The study didn't look at how the caffeine affected people's health.

No regulatory check: The study didn't check if the products followed FDA or WADA guidelines.

The Bottom Line: Be a smart consumer! Read labels carefully, and consider choosing supplements that have been independently tested to ensure you know exactly what you're putting into your body.

Key Findings

The study detected caffeine in 64% (16/25) of sports supplements marketed as containing orchid-derived ingredients, despite caffeine not being listed on product labels. Quantified caffeine levels ranged from 8.2–198.5 mg per serving, with 40% of contaminated products exceeding the recommended daily intake of 400 mg caffeine per 100g of body weight. Researchers concluded that mislabeling and undeclared caffeine presence pose risks for athletes subject to doping regulations and consumers seeking stimulant-free products.

Study Design

This cross-sectional analysis tested 25 commercially available sports supplements labeled as containing orchid extracts (e.g., Orchis mascula). Using high-performance liquid chromatography (HPLC), researchers quantified caffeine and orchid-specific compounds. The study spanned 6 months (2024–2025) and included products from 12 countries. No demographic data on users were reported, as the focus was on product composition rather than human outcomes.

Dosage & Administration

The study did not involve human administration. Caffeine content was measured in existing supplements. Detected doses varied widely: 8.2 mg in one product to 198.5 mg in another, equivalent to 0.05–1.2 cups of coffee per serving. Orchid compounds were present in all products but at inconsistent concentrations (0.5–12.3 mg/g).

Results & Efficacy

Caffeine was identified in 16 supplements with 95% confidence intervals (CI) for contamination rates ranging from 42.3%–78.9%. The highest caffeine concentration (198.5 mg) exceeded the European Food Safety Authority’s acute safety threshold (200 mg/serving). Label claims for orchid content aligned with measured levels in only 58% of products (p < 0.01). No correlation was found between caffeine presence and orchid compound concentrations (r = 0.12, p = 0.56).

Limitations

Sample Scope: Limited to 25 products from 12 countries, potentially underrepresenting global markets.
Analytical Focus: Tested only caffeine and orchid markers, excluding other stimulants or adulterants.
Lack of Clinical Data: Did not assess physiological effects of detected caffeine levels in humans.
No Regulatory Context: Did not evaluate compliance with FDA or WADA guidelines for labeling accuracy.
Future research should expand testing to include diverse products and investigate health impacts of chronic low-dose caffeine exposure in susceptible populations.

Clinical Relevance

Supplement users, particularly athletes, may unknowingly ingest performance-enhancing stimulants like caffeine, risking anti-doping violations or adverse effects (e.g., tachycardia, insomnia). The findings underscore the need for third-party certification programs and stricter regulatory oversight. Consumers seeking orchid-based supplements should prioritize products with transparent ingredient panels and NSF/Informed-Choice certifications to avoid unintended caffeine exposure.
