Standardized Extract

What is a Standardized Extract?

A standardized extract is a form of herbal extract that guarantees a specific amount of active substance. This means that each batch of the extract contains a consistent dose of the active compounds responsible for its health-promoting properties. This standardisation is crucial to ensure that the user receives a reliable and effective dose of the substances considered beneficial.

Standardized extracts are often used in dietary supplements and health products to provide consumers with confidence that they are getting exactly what they pay for. Without standardisation, the amount of active ingredients can vary greatly between batches, which may lead to undesired results and lack of effects.

How does it work in the body?

When standardized extracts are ingested, the active substances are absorbed into the body and interact with various biological systems. Depending on the type of extract, these substances can affect everything from inflammation and immune function to brain function and digestion.

The active compounds in these extracts can act in different ways. Some may function as antioxidants, while others may support the body's natural processes. The standardized dose ensures that the effect is predictable and that the user achieves the desired results.

Scientific benefits

Several studies have investigated the effects of standardized extracts. Here are some examples of scientifically supported benefits:

• Green tea extract: Research has shown that standardized extracts of green tea can increase fat burning and support weight loss through their natural antioxidants, especially epigallocatechin gallate (EGCG).
• Ginseng: A study published in The Journal of Alternative and Complementary Medicine demonstrated that standardized ginseng extract can improve physical performance and reduce fatigue.
• Curcumin: Standardized curcumin extract has been shown to have anti-inflammatory properties and may help support joint health, according to a review article in Journal of Medicinal Food.

Dosage and recommendations

The dosage of standardized extracts varies depending on the type of extract and the active substance. It is important to follow the recommendations on the product label or consult a health specialist. Generally, the following guidelines can be used:

• For green tea extract: 250-500 mg per day with a standardisation of 50% EGCG.
• For ginseng: 200-400 mg per day of a standardized extract containing at least 5% ginsenosides.
• For curcumin: 500-1000 mg per day of a standardized extract with high bioavailability.

Best sources and forms

Standardized extracts are available in several different forms, including capsules, tablets, powders, and liquid extracts. Some of the most popular sources of standardized extracts include:

• Green tea extract: Available as capsules and powder.
• Ginseng extract: Available in capsules and as liquid extract.
• Curcumin extract: Available in capsules and powder, often combined with black pepper for increased absorption.

Side effects and warnings

Although standardized extracts are often considered safe, some individuals may experience side effects. Common side effects may include:

• Gastrointestinal discomfort, such as nausea or diarrhoea.
• Allergic reactions in sensitive individuals.
• Interactions with certain medications, especially blood thinners.

It is always important to consult a doctor before starting a new dietary supplement, especially if you have underlying health conditions or are taking medications.
