Supplements That May Be Worth Considering
A High-Quality Multivitamin
One of the most common side effects of Concerta is a reduced appetite. If you're eating less than usual or struggling to maintain a varied diet, a well-formulated multivitamin can help support your overall nutritional intake. Look for one that uses bioavailable nutrient forms and avoids unnecessary fillers.
(TRINITY is pharmacist formulated, uses bioavailable nutrient forms and separates nutrients across Morning, Day and Night formulations.)
Protein
If reduced appetite means you're missing meals or eating smaller portions, prioritising protein can help support muscle maintenance and overall nutrition. While whole foods should come first, a protein supplement may be a practical option if you're struggling to meet your daily requirements.
Omega-3
If you don't regularly eat oily fish, an omega-3 supplement may be worth considering. Omega-3 fatty acids contribute to normal heart function and form part of a healthy, balanced diet.
Functional Mushrooms
Some people choose functional mushrooms such as lion's mane, cordyceps and chaga to support focus, cognitive performance and overall wellbeing. They aren't a replacement for ADHD medication but may complement a healthy lifestyle.
(MYCO Morning contains organic lion's mane, cordyceps and chaga mushroom extracts, with no fillers or unnecessary additives.)
Magnesium
Magnesium isn't routinely recommended because you're taking Concerta, but it may be appropriate if your dietary intake is low. It contributes to normal psychological function, normal nervous system function and the reduction of tiredness and fatigue.
(Magnesium Complex contains magnesium bisglycinate and magnesium taurate with no magnesium oxide.)
Supplements to Avoid (or Use with Caution)
Most supplements can be taken safely with Concerta (methylphenidate). However, some may increase stimulant-related side effects or interact with your medication.
| Supplement | Recommendation | Why? |
|---|---|---|
| High-caffeine supplements | ⚠️ Use with caution | Combining high doses of caffeine with Concerta may increase side effects such as a racing heart, anxiety, jitteriness or difficulty sleeping. |
| Pre-workout supplements | ⚠️ Check the ingredients | Many contain high amounts of caffeine or other stimulants that may have an additive effect with Concerta. |
| Weight-loss supplements | ⚠️ Avoid unless advised | These often contain stimulants that may further suppress appetite or increase heart rate and blood pressure. |
| Herbal stimulant supplements | ⚠️ Use with caution | Ingredients such as guarana and yohimbe may enhance stimulant effects and aren't suitable for everyone taking methylphenidate. |
If you're considering a supplement to improve energy, focus or concentration, check the ingredients carefully. Products containing multiple stimulants may increase the risk of unwanted side effects without providing additional benefit.
