PharmaLinea, a private label food supplement manufacturer from Slovenia, is proud to announce that its manufacturing facility has been officially certified by the THE GOOD PILL CO. certification programme, recognising the company’s commitment to the highest standards for quality, safety and transparency in supplement manufacturing.
Recent reports have exposed serious safety concerns, with nearly 40% of supplements tested in 2023 either failing to meet label claims or containing harmful contaminants.
These issues have created a sense of mistrust among consumers and raised concerns about industry accountability.
For example, a recent case involving UK brand Nutrition Ignition has revealed that the company’s magnesium glycinate gummies intended for children aged 4 and older contained 1.5–1.7 mg of melatonin, which was not disclosed on the product label.
Another 2025 investigation by Niagein Bioscience highlighted that only 24% of the 21 best-selling NAD+ supplements on Amazon contained the advertised amount of NAD+, with 11 of
analysed products showing no detectable NAD+ at all.
“Several factors are contributing to the quality challenges in the supplement industry, economic pressure being among the most prominent ones,“ explained PharmaLinea’s Technical Director, Denis Đalapa.
“For certain raw materials, where there’s a large number of suppliers on the market, cost optimisation often comes at the expense of quality. The biggest quality issue we’re encountering during our production process is with plant extracts, which are often exposed to contamination."
"In some markets, low environmental and regulatory awareness can worsen the issue of substandard production environment, allowing contaminants to enter the supply chain. Additional factors include a lack of high-quality raw materials and limited access to advanced testing technologies.“
In response to these industry wide concerns, PharmaLinea’s manufacturing facility has adopted a comprehensive quality control approach and implemented several rigorous testing protocols throughout the production cycle, including
- incoming inspection and identification of raw materials
- specific contaminant testing, including PAHs (polycylic aromatic hydrocarbons) and PA (pyrrolizidine alkaloids)
- testing of intermediates
- microbiological and heavy metal analysis on all finished products
- stability studies to ensure safety and efficacy throughout shelf-life.
“THE GOOD PILL Co.’s mission aligns closely with ours: ensuring consumers have access to safe, efficient and science-backed supplements,“ commented PharmaLinea’s Marketing Director, Matevž Ambrožič.
“This certification validates what we already implement internally and allows us to contribute to setting higher industry benchmarks for transparency and trust.“
