5-HTP May Benefit Fibromyalgia Sufferers By Assisting with Pain Relief, Sleep Quality, and More

Take 5-HTP for fibromyalgia as a way to boost serotonin levels and help relieve pain.

5-htp supplements offer benefits

One of the 5 htp benefits for treating fibromyalgia is boosting serotonin levels and relieving pain.

For reasons yet to be fully understood, people with fibromyalgia feel more pain than normal. Fibromyalgia sufferers’ brains show activation patterns in pain processing areas when only mild pressure or heat is applied.[1] Researchers believe that part of what contributes to fibromyalgia is an imbalance of the neurotransmitter serotonin. This is why 5-hydroxytryptophan (5-HTP), a precursor to serotonin, is one of the more effective fibromyalgia supplements. 5 HTP benefits for fibromyalgia include boosting serotonin levels and helping to relieve pain.

Fibromyalgia and serotonin

Serotonin is an important neurotransmitter with a major role in sleep, pain, and appetite, and it affects conditions like depression and anxiety. It influences pain thresholds through interacting with other compounds involved in the sensation of pain, like substance P and endorphins.[2] Serotonin is also important for getting restorative sleep.[3] Disruptions in serotonin metabolism have been reported as a hallmark characteristic of fibromyalgia, with fibromyalgia patients showing marked reductions in serotonin levels.[2,3]

Common drugs used to effectively treat fibromyalgia include those that increase the activity of serotonin, including tricylic antidepressants and selective serotonin reuptake inhibitors (SSRIs).[1] However, the effects of these drugs can be far wider than just reducing pain, as they can alter mood and have other unpleasant physical side effects. So how else can you safely increase serotonin activity to help treat fibromyalgia?

5-HTP – a serotonin booster

The synthesis of serotonin in the body begins with L-tryptophan, one of the essential amino acids we get through diet. L-tryptophan is converted to 5-HTP, which is in turn converted to serotonin. While L-tryptophan is readily converted into substances other than serotonin, such as niacin, 5-HTP cannot be degraded or converted into other substances. It also crosses the blood-brain barrier easier than L-tryptophan itself.[2] This makes 5-HTP a valuable option for efficiently boosting serotonin levels in the body. What’s more, it is found naturally in seeds of the plant Grifonia simplicifolia.[2]

5-HTP Benefits

In a double-blind study in fibromyalgia patients, 100 mg of 5-HTP three times a day for 30 days led to a significant reduction in number of tender points and intensity of pain compared to placebo. Patients also experienced improvement in morning stiffness, sleep patterns, fatigue, and anxiety.[3] Similar results were found after only 15 days and up to 90 days using the same dosage.[4]

Using 5-HTP for fibromyalgia treatment

Studies show that effective dosages range from 200 to 1,000 mg of 5-HTP daily. Side effects are minimal, with mild nausea being the most common, so take it with meals. Consider taking vitamin B6 as well, because it helps to convert 5-HTP to serotonin.[2]

As always, talk with your doctor before beginning new supplements. Do not take 5-HTP with antidepressants that also increase serotonin activity, as too much serotonin can be dangerous.

  • Am currently taking 5-HTP but will up my dosage to 200mg to test. So far the best thing I have found for reducing fibro pain is a strict keto diet. Works great as long as I keep carbs really low and fats high.

  • Hello, I have just ordered 5-HTP for my severe fibromyalgia and ME. All the information online about dosage and how long it can be taken for, are very confusing. If this can only be taken for 12 weeks what will I do after that, the fibromyalgia is not going to disappear. Please can you help me I would be very grateful for some answers! Many thanks

    I was diagnosed with fibromyalgia for 3 years, and it was very painful some days. I was taken methocarbamol to relieve the pain. Sometimes it helps and other days it doesn’t. it was killing me for 3 years, doctor said there was no cure. So I tried to live with it and it wasn’t easy.My childhood friend introduced me to Dr George (Good health herbs home),Dr George fibromyalgia herbal remedy cured me within 6 weeks of usage ,am fibromyalgia free now 100%.

  • I am Allen Swift i was diagnosed with fibromyalgia. I have from moderate to severe pain in most parts of my body, been tested for a lot of things and all came back ok. I have had a lot of stomach pain, there was a day i received a message from my old time friend who has been away for many years he told me he heard about my illness and he directed me to Standard Herbs Home and i contacted them and purchased their herbal medicine and followed the instructions after 4 weeks i was cure from fibromyalgia. Thanks to STANDARD HERBS HOME.

  • I have been living with this condition for a long time. the 5htp has worked but the issue is that taking that along can throw off your other neurotransmitters and feel very painful spasms. I figured out that if you take Acetyl L-carnitine (500 to 1000mg) a day can help as it brings up the level of Norepinephrine. I also take L-Tyrosine, every other day along with PhosphatidylCholine. I am going to try that Best Herbal Centre, sounds promising
