Thorne’s “No List”

Ingredients That Will Never Be in Thorne's Supplements

At Nutrition Capital, we proudly stock Thorne, a brand that stands firm on uncompromising purity and transparency.
When it comes to nutritional supplements, not all products are created equal. Many brands cut corners with fillers, preservatives, and artificial additives that do nothing for your health – and may even put it at risk. Thorne takes a bold stance with their No List, a strict blacklist of ingredients that will never appear in their supplements.

This commitment ensures that every Thorne product delivers clean, high-quality formulations without hidden compromises. Athletes, health professionals, and everyday individuals choose Thorne because of their dedication to safety, integrity, and science-backed excellence.

Why Thorne’s No List Matters

Unlike many supplement brands, Thorne refuses to include artificial sweeteners, harmful preservatives, banned substances, and controversial fillers. This makes their products a trusted choice for those who want supplements free from unnecessary and potentially dangerous compounds.

Key reasons the No List is non-negotiable:

• Protects against toxins, carcinogens, and endocrine disruptors.

• Avoids artificial colours, flavours, and preservatives linked to allergies and hyperactivity.

• Provides peace of mind for athletes by excluding over 200 banned substances.

• Ensures better absorption and bioavailability by avoiding additives that interfere with nutrient uptake.
