Myths vs. Facts - Metabolism Support Supplements

There is a lot of misleading information about food supplements online. Here we address common misconceptions with factual, evidence-based context.

MYTH

"Food supplements can guarantee weight loss or specific body changes."

FACT

No food supplement is authorised to make such a claim. Supplements support nutrition as part of a varied diet and healthy lifestyle - they are not treatments and do not guarantee results. Individual results vary.

MYTH

"All plant extracts are automatically safe at any dose."

FACT

Plant extracts are included in food supplements at safe, regulated levels. It is important to follow recommended daily doses and consult a healthcare professional if you have a pre-existing condition or take medication.

MYTH

"Chromium supplements treat diabetes or blood sugar disorders."

FACT

Chromium is an EFSA-noted nutrient associated with the maintenance of normal blood glucose levels at adequate dietary intake. This is a nutrient-level role in the context of normal physiology - not a claim that any product treats, cures or prevents any disease.

MYTH

"You need to take high doses to see any benefit from B vitamins."

FACT

B vitamins are water-soluble and the body uses what it needs. EFSA-registered claims for B vitamins relate to their contribution at normal dietary levels - megadosing is not necessary and may not be appropriate. Follow the stated NRV on the label.
