Last updated: · By the Slimqa Slim Coffee Booster Guide editorial team

This is general safety information, not medical advice. Because the full ingredient amounts are not published, the cautious approach is to ask a professional before you start if any of the points below apply to you.

  • Not for under 18s, and a food supplement is not a replacement for a balanced diet and activity
  • Ask a GP or pharmacist first if you are pregnant, breastfeeding, on medication or have a medical condition
  • Stimulants: caffeine and bitter orange (if present) matter for sensitive people

Safety: our short view

Do not rely on the seller's pages for safety information. We could not find amounts per sachet, so the risks cannot be properly judged. If any of the groups below apply to you, speak to a GP or pharmacist first. If you feel unwell after taking it, stop and seek advice.

Who should ask a professional first

Slimqa is a food supplement, not a medicine. It is not for under 18s. Please speak to a GP or pharmacist before using it if any of the following apply:

  • You are pregnant, breastfeeding or trying to conceive.
  • You take any prescription or over-the-counter medicine.
  • You have a medical condition, including diabetes or a heart or blood-pressure issue.
  • You have an eating disorder or a history of one. Please speak to a GP before using any weight-control product.

If you are unsure whether a medicine you take interacts with any of the ingredients, a community pharmacist can usually check quickly and without an appointment.

Our general information cannot replace advice that takes your own history into account.

Ingredients that call for extra care

The seller's pages name different ingredients and give no amounts, so we can only describe the general concerns.

  • Berberine is named on both pages. People who take diabetes or other prescription medicines, or who are pregnant or breastfeeding, should ask a GP or pharmacist about it.
  • Green tea extract has been linked to rare liver problems at high intakes. Do not combine several green tea products without advice.
  • Bitter orange, which the offer page names, and caffeine from coffee and green tea ingredients matter for people sensitive to stimulants or with heart or blood-pressure issues.
  • Anything else on the pack: if you have an allergy or intolerance, read the allergen information on the label and ask the seller if it is unclear.

Some people notice jitteriness, a fast heartbeat, trouble sleeping or an upset stomach from stimulants. If you notice anything like that, stop and seek advice.

Using any supplement sensibly

A few habits apply to every supplement, including this one.

  • Read the whole label when the pack arrives and follow the directions printed on it.
  • Count the caffeine you already have from coffee, tea and other drinks.
  • Do not use it as a replacement for a balanced diet, activity or medical care.
  • Tell a healthcare professional what supplements you take, especially before an operation or a new prescription.
  • Keep it out of reach of children.

When to stop and get advice

Stop using it and seek advice if you feel unwell. Contact a GP, pharmacist or NHS 111 if symptoms are worrying, and seek urgent help in an emergency. You can also report a suspected side effect of a food supplement to your local authority's trading standards or the Food Standards Agency.

Remember that the seller's return policy only covers unopened packs, so decide on safety before you open it. For more on the seller see our scam or legit guide and the main Slimqa guide.
