About Only Natural

Product Specialization

Only Natural focuses on supplements in the fish oil and herbal categories. They offer a variety of products, including herbal extracts and fish oil capsules.

Testing & Certifications Explained

Only Natural does not have any third-party certifications on record. This means there is no independent verification of the quality, purity, or potency of their supplements. Consumers should be aware that the absence of certifications means there's no external assurance that the product contains what the label claims and is free from contaminants. Therefore, it's difficult to definitively answer 'is Only Natural third-party tested'.

How Only Natural Compares

Compared to other brands in the fish oil and herbal supplement categories, Only Natural's Trust Score of 50/100 is lower than brands that prioritize third-party testing. For example, Nordic Naturals (Trust Score 85/100) and NOW Foods (Trust Score 78/100) both have higher scores due to their commitment to certifications and testing. These brands may provide greater assurance of product quality and safety.

Buying Guidance

Given Only Natural's Trust Score, consumers should carefully consider their options before purchasing. While 'is Only Natural a good brand' is subjective, it's advisable to look for third-party tested supplements from brands with higher trust scores for greater assurance of quality. Purchase from reputable retailers and carefully review product labels.
