Supplements & GLP-1 medication
A balanced, plain-English overview of what people typically weigh up when considering weight-loss medication and supplements alongside ADHD or peri-menopause support.
Speak to your GP first. This page is for education only — it isn't medical advice. Please talk to your GP, pharmacist or a qualified clinician before starting, stopping or changing any medication, supplement or weight-loss programme, especially if you are pregnant, breastfeeding, take other medication or have an existing health condition.
GLP-1 weight loss medication (e.g. semaglutide, tirzepatide)
Pros
- Clinically significant weight loss for many people when combined with lifestyle changes.
- Reduces appetite and 'food noise', which can be especially helpful with ADHD-related impulsive eating.
- Improved blood sugar control and cardiometabolic markers for some patients.
- Prescribed and monitored by a clinician, with dose titration.
Cons & risks
- Common side effects: nausea, constipation, reflux, fatigue, especially during dose increases.
- Rare but serious risks: pancreatitis, gallbladder issues, severe dehydration.
- Muscle mass loss if protein intake and resistance training aren't prioritised.
- Weight regain is common if the medication is stopped without a sustainable plan.
- Not suitable in pregnancy, with certain thyroid histories, or alongside some medications.
- Cost, availability and interactions with HRT or ADHD medication should be reviewed with your GP.
Supplements (vitamins, minerals, adaptogens)
Pros
- Can help fill gaps if intake drops on a GLP-1 (e.g. protein, fibre, electrolytes, B12).
- Targeted support for peri-menopause symptoms (e.g. magnesium, omega-3, vitamin D).
- Some evidence for cognitive and mood support in ADHD (e.g. omega-3, iron if deficient).
- Non-prescription and widely available.
Cons & risks
- 'Natural' does not mean safe — supplements can interact with prescribed medication.
- Quality varies widely; unregulated dosages and contaminants are a real risk.
- Fat-soluble vitamins (A, D, E, K) and iron can be harmful in excess.
- May mask symptoms that need proper investigation (e.g. anaemia, thyroid issues).
- Cost adds up, and marketing often overstates the evidence.
Combining GLP-1, HRT and ADHD medication
Pros
- Many people report that treating peri-menopause, ADHD and weight together improves quality of life.
- A single clinician overseeing the picture can spot interactions early.
Cons & risks
- Absorption and side-effect profiles can shift when appetite and gut motility change.
- Stimulant appetite suppression + GLP-1 can compound under-eating and dehydration.
- Mood changes during peri-menopause can be mistaken for medication side effects and vice versa.
- Requires regular review — don't self-adjust doses.
Questions to bring to your GP
- Is this medication or supplement appropriate for my health history?
- How does it interact with anything else I take (HRT, ADHD meds, contraception)?
- What side effects should prompt me to stop or call for help?
- How will we monitor progress — bloods, weight, mood, muscle mass?
- What's the plan if I want to stop, and how do we protect against rebound?
