Supplements That May Be Worth Considering
Functional Mushrooms
Many people taking venlafaxine are looking for ways to support their focus, concentration and overall wellbeing alongside their prescribed treatment. Functional mushrooms such as lion's mane, cordyceps and chaga are increasingly popular for these reasons.
Although they aren't intended to treat depression or anxiety, they may be a useful addition to a healthy lifestyle for some people.
(MYCO Morning contains organic lion's mane, cordyceps and chaga mushroom extracts, with no fillers or unnecessary additives.)
A High-Quality Multivitamin
If you're looking to support your overall nutritional intake, a well-formulated multivitamin can be a sensible choice. Look for one that uses bioavailable nutrient forms, avoids unnecessary fillers and provides comprehensive nutritional support.
(TRINITY is pharmacist formulated, uses bioavailable nutrient forms and separates nutrients across Morning, Day and Night formulations.)
Magnesium
If your dietary intake of magnesium is low, supplementation may be worth considering. Magnesium 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.)
Vitamin D
If you have limited sun exposure, have been advised your vitamin D levels are low or are at increased risk of deficiency, supplementation may be appropriate. Vitamin D contributes to the normal function of the immune system and the maintenance of normal bones.
Omega-3
If you don't regularly eat oily fish, an omega-3 supplement may help support your overall nutritional intake. Omega-3 fatty acids contribute to normal heart function as part of a healthy, balanced diet.
Supplements to Avoid (or Use with Caution)
Most supplements can be taken safely with venlafaxine (Effexor XL). However, some can increase serotonin levels or affect how your medication works, so they're best avoided unless advised by your healthcare professional.
| Supplement | Recommendation | Why? |
|---|---|---|
| St John's wort | ⛔ Avoid | St John's wort can increase serotonin levels and should not be taken with venlafaxine due to the risk of serotonin syndrome. |
| 5-HTP | ⛔ Avoid | 5-HTP increases serotonin production and isn't recommended alongside venlafaxine. |
| L-Tryptophan | ⚠️ Avoid unless advised | L-tryptophan may increase serotonin levels and shouldn't routinely be combined with venlafaxine. |
| Mood support supplements containing multiple active ingredients | ⚠️ Check the label | Some products contain serotonin-boosting ingredients that may not be suitable to take with SNRIs. |
If you're thinking about taking a supplement to support mood, stress or anxiety, speak to your GP or pharmacist first. Choosing supplements that support your general health is usually a safer approach than combining venlafaxine with products designed to alter serotonin levels.
