Why Herbal Supplement Quality Matters

When you choose an herbal supplement, you want to feel confident that it contains the right ingredient, from the right plant, and the right part of that plant. That matters because herbal ingredients can be complex, and in some cases, lower-quality products may be adulterated with cheaper or unwanted plant materials.

You should be able to trust that the supplement you choose is made with carefully selected ingredients and tested with precision. Advanced herbal testing helps support:

• Confidence that the ingredient is what it claims to be
• Assurance that the correct plant part is used for the intended health benefit
• Protection against common forms of adulteration
• Greater trust in the quality, purity, and potency of the finished product

How Does Jamieson Test Herbal Supplements?

At Jamieson, quality testing is a key part of our 360 Quality Program. For botanical ingredients, we use an advanced testing method called High Performance Thin Layer Chromatography, or HPTLC, to help verify the identity and purity of herbal ingredients.

What Is HPTLC?

HPTLC stands for High Performance Thin Layer Chromatography. HPTLC is a specialized step-by-step technique used to separate and identify the natural compounds found in plant-based ingredients. Think of it like a fingerprint test for herbs: it helps confirm that the ingredient matches an authenticated reference and that it has not been replaced or diluted with something else. 

How Does It Work?

Imagine you asked for an apple and were handed a tomato. Both are red, round, and healthy—but they are clearly not the same. Herbal ingredients work in a similar way. Plants can look alike or come from related species, but their natural compounds may be very different.

HPTLC helps Jamieson look beyond appearance and verify the ingredient at a deeper level. It can also help confirm whether the correct part of the plant is being used, such as the root, fruit, leaf, or flower, because different plant parts can provide different health benefits.

What Does HPTLC Verify?

Using HPTLC, Jamieson can gather detailed information about botanical raw materials, including:

• Identity: confirming the botanical ingredient matches an authenticated reference.
• Purity: checking for known adulterants or substitute plant materials.
• Correct plant part: helping verify that the expected root, leaf, fruit, or other plant part is being used.
• Consistency: supporting reliable quality from formulation to finished product.
