Lion's Mane and Sertraline: Can You Take Them Together?

Quick Answer

Yes, in most cases, Lion's Mane can be taken alongside sertraline.

There are currently no well-established interactions between Lion's Mane (Hericium erinaceus) and sertraline. However, research on this combination is limited, so it's sensible to introduce any new supplement cautiously and discuss it with your GP or pharmacist if you have any concerns.

Many people taking sertraline are interested in Lion's Mane because of its reputation for supporting cognitive function, focus and overall wellbeing. While early research into Lion's Mane is promising, it shouldn't be viewed as a replacement for sertraline or any other prescribed antidepressant.

In this guide, we'll explain:

• Whether Lion's Mane interacts with sertraline.

• What the current research says.

• Who may wish to use extra caution.

• How to choose a high-quality Lion's Mane supplement.

Pharmacist's Verdict

Is It Safe to Take Lion's Mane with Sertraline?

For most healthy adults, there's currently no evidence of a clinically significant interaction between Lion's Mane and sertraline.

Unlike supplements such as St John's wort or 5-HTP, Lion's Mane isn't known to directly increase serotonin levels. This means it isn't thought to carry the same risk of serotonin syndrome when taken alongside SSRIs such as sertraline.

That said, the evidence is still developing. Most research on Lion's Mane has investigated its potential effects on cognitive function and nerve health rather than its use alongside antidepressants. Human studies specifically looking at people taking both Lion's Mane and sertraline are currently lacking.

For that reason, it's sensible to:

• Choose a high-quality Lion's Mane supplement from a reputable manufacturer.

• Introduce one new supplement at a time.

• Monitor for any unexpected side effects.

• Speak to your GP or pharmacist if you take multiple medicines or have a long-term medical condition.

In the next section, we'll look at why people taking sertraline are interested in Lion's Mane and what the current evidence says about its potential benefits.

Why Do People Take Lion's Mane with Sertraline?

People usually aren't looking to replace sertraline with Lion's Mane. Instead, they're often interested in whether it can complement their overall wellbeing while continuing their prescribed treatment.

Research into Lion's Mane is still emerging, but it has attracted interest because it contains naturally occurring compounds called hericenones and erinacines, which have been studied for their potential effects on nerve growth factor (NGF) and brain health. Much of this research has been carried out in laboratory and animal studies, so more high-quality human trials are needed.

Some people choose to take Lion's Mane alongside sertraline in the hope of supporting:

• Cognitive function and focus

• Memory and concentration

• Overall wellbeing

• Everyday productivity

At present, there isn't strong evidence to show that Lion's Mane improves depression or anxiety when added to sertraline, and it shouldn't be considered a substitute for prescribed treatment. However, current evidence also doesn't suggest that the two shouldn't be taken together in most healthy adults.

If you decide to try Lion's Mane, choose a high-quality product that uses 100% fruiting body extracts, clearly states its extraction method and avoids unnecessary fillers or proprietary blends.

Choosing a High-Quality Lion's Mane Supplement

Not all Lion's Mane supplements are created equal. The quality of the raw material, extraction process and formulation can vary considerably between brands.

When comparing products, look for:

• 100% fruiting body extracts rather than mycelium grown on grain.

• Clearly stated extraction methods, such as hot water extraction, to help release beneficial compounds.

• Transparent labelling showing exactly what's included.

• No unnecessary fillers, binders or proprietary blends that make it difficult to know what you're taking.

• Independent quality testing, where available.

If you're considering a blend rather than a single-mushroom supplement, think about whether the additional mushrooms complement your goals. For example, Lion's Mane is often paired with cordyceps and chaga in formulations designed to support cognitive function, energy and overall wellbeing.

(MYCO Morning contains organic hot water-extracted lion's mane and chaga, plus hot water and ultrasonic extracted cordyceps, using 100% fruiting body mushrooms with no fillers or unnecessary additives.)

Ultimately, the quality of the mushroom extract is likely to be more important than choosing the product with the highest advertised dose.

Who Should Use Extra Caution?

Although Lion's Mane is generally well tolerated, it isn't suitable for everyone.

Speak to your GP or pharmacist before taking Lion's Mane if you:

• Take multiple prescription medicines, particularly medicines that affect blood clotting or the immune system.

• Have a history of mushroom allergies.

• Are pregnant or breastfeeding, as there is limited safety data available.

• Have a long-term medical condition and are unsure whether supplements are appropriate for you.

If you start taking Lion's Mane alongside sertraline, introduce it gradually and monitor for any unexpected side effects. If you notice a rash, swelling, difficulty breathing or any other signs of an allergic reaction, stop taking the supplement and seek urgent medical attention.

For most people taking sertraline, the main priority is to continue taking their prescribed medication as directed and to view Lion's Mane as a supplement to a healthy lifestyle—not a replacement for evidence-based treatment.

Frequently Asked Questions

Can I take Lion's Mane with sertraline?

Yes. There are currently no well-established interactions between Lion's Mane and sertraline. Most people can take them together safely, but if you have a long-term medical condition or take multiple medicines, speak to your GP or pharmacist before starting any new supplement.

Does Lion's Mane increase serotonin?

There is currently no good evidence that Lion's Mane directly increases serotonin levels in the way supplements such as 5-HTP or St John's wort can. This is one reason why it isn't thought to carry the same interaction risk with SSRIs such as sertraline.

Can Lion's Mane cause serotonin syndrome?

There are no well-documented reports of Lion's Mane causing serotonin syndrome when taken with sertraline. However, research on this combination is still limited, so it's sensible to use reputable products and seek professional advice if you're unsure.

Can I take MYCO Morning with sertraline?

Yes. There are no well-established interactions between sertraline and the mushrooms found in MYCO Morning, including Lion's Mane, Cordyceps and Chaga. As with any supplement, introduce it gradually and speak to your GP or pharmacist if you have concerns or take multiple medicines.

Can Lion's Mane help anxiety or depression?

Research is still in its early stages. While some preliminary studies have investigated Lion's Mane and mood, there isn't enough high-quality evidence to recommend it as a treatment for anxiety or depression. It shouldn't replace prescribed medication.

Can I take Lion's Mane every day?

For most healthy adults, daily use is generally considered acceptable when taken as directed. Follow the manufacturer's instructions and speak to your healthcare professional if you're unsure whether it's appropriate for you.

Who shouldn't take Lion's Mane?

People with a mushroom allergy should avoid Lion's Mane. If you're pregnant, breastfeeding, taking multiple medicines or have a long-term medical condition, speak to your GP or pharmacist before starting it.

Should I stop taking sertraline if I start Lion's Mane?

No. Continue taking sertraline exactly as prescribed. If you're considering any changes to your antidepressant treatment, discuss them with your GP rather than relying on supplements.
