Nutraceuticals – Guide
KINGRAY nutraceuticals: compare composition, nutrient claims and categories
Welcome to the KINGRAY Nutraceuticals Buying Guide. Compare 22 products in the blue range in one table: what they contain, which authorised health claims we use for their nutrients, and which topics they belong to. Choose a product to view its complete composition, daily amounts and warnings.
How to read the table
Product names link to composition, recommended intake and complete warnings. The ingredient summary is not a replacement for the full label.
Health claims refer to specific nutrients and their conditions of use. They do not establish the combined effect of the whole formula or superior efficacy of a chemical form.
Categories help you browse topics. Longevity, biohacking and mitochondria do not promise a longer life, rejuvenation or mitochondrial repair. Evening-routine placement alone does not establish an effect on sleep.

Simply put
Choose by composition and the nutrients involved, rather than the product name alone. Two products containing the same vitamin may use the same authorised claim despite having different other ingredients. Taking more products together is not necessarily a better choice.
Before combining supplements
Check the total intake of vitamins and minerals across all supplements. Products containing green tea may instruct you not to take other green-tea products on the same day or use them on an empty stomach. Follow the particular product label.
If you take medicines affecting blood clotting, pay particular attention to vitamin K, Q10 and enzyme complexes. With iron, consider total intake and possible excess. Consult a doctor or pharmacist if you take diabetes medication, have liver or kidney disease, or are planning a procedure.
Full contraindications, allergens and age restrictions are provided with each product. Several formulations are not intended for children or for pregnant or breastfeeding women.
Frequently asked questions
Which product extends life?
No product in this guide is presented as having a proven life-extending effect. The longevity category links interest in composition with healthy-ageing topics.
Why do some products have no health claim?
Not every ingredient has an applicable authorised EU claim. For those products we describe composition and form without attributing health effects. Research on an ingredient does not permit arbitrary health promises in advertising.
Does “on hold” mean approved?
No. This guide does not use botanical claims under the “on hold” regime. Selected authorised nutrient claims are used subject to their conditions.
Does KING Beauty Collagen Synergy contain collagen?
Not according to the declared composition. It contains vitamin C, which contributes to normal collagen formation for the normal function of skin.
Should I take every product in a category?
No. This is a comparison of options. Consider your diet, medicines, other supplements and the manufacturer’s warnings.
