About Manitoba Harvest

Manitoba Harvest is a brand specializing in hemp and protein products. Founded in 1998, the company has been in operation for 28 years. Manitoba Harvest is now owned by parent company Tilray and headquartered in the US.

Product Specialization

Manitoba Harvest focuses on hemp and protein products. They are known for offering a variety of hemp-based foods, including hemp seeds, hemp protein powder, and hemp oil. These products cater to consumers seeking plant-based protein and nutritional supplements.

Testing & Certifications Explained

Manitoba Harvest carries USDA Organic certification. This means that their products meet specific standards set by the USDA regarding how they are grown and processed. However, no third-party testing certifications were found. This means that there is no readily available evidence of independent labs verifying the purity, potency, and safety of Manitoba Harvest products.

How Manitoba Harvest Compares

Compared to competitors like Nutiva (Trust Score: 78/100) which has third-party testing certifications, Manitoba Harvest's lack of such certifications is a notable difference. Another competitor, Garden of Life (Trust Score: 82/100), also demonstrates a higher level of transparency and testing. These brands may offer consumers more assurance through their commitment to independent verification.

Buying Guidance

Given Manitoba Harvest's Trust Score of 65/100 and the absence of third-party testing certifications, consumers should carefully consider their options. Look for the USDA Organic certification on product packaging. Purchasing from reputable retailers may also provide some additional assurance.
