Supplements

What I take every day, my target blood levels and selected supplements in detail.

Updated: October 2026

For most supplements, the evidence in Parkinson's comes only from lab and animal experiments or from small studies. There is not a single product with large studies that prove an effect on the course of the disease. High-dose coenzyme Q10 and creatine even showed no benefit in large Parkinson's studies. It does make sense, though, to correct real deficiencies, for example in vitamin D, vitamin B12 or omega-3. And even with vitamins you can take too much: in high doses, vitamin B6 can damage the nerves.

My most important advice: Have your blood levels checked and correct real deficiencies in a targeted way. And discuss everything with your doctor.

What I take every day

Amounts are given as morning-noon-evening.

Basics

Vitamin-B-Komplex active (Biogena): 1 capsule, every other day in the morning
Vitamin C: 1,000 mg, 2-0-1
Vitamin D3 (NatuGena Forte): 5,000 IU, 1 drop in the morning, only as needed depending on my blood level
Vitamin E (Tocomin SupraBio): 1 capsule in the morning
Omega-3 from fish oil (Vitality UltraPure, on the recommendation of Dr. Guschlbauer): 2 capsules a day, each capsule with 400 mg EPA and 300 mg DHA (before that, omega-3 from algae by Norsan)
Magnesium-Komplex 9 Ultra (Sunday Natural): 100 mg, 2-0-2
Magnesium L-threonate: 2,000 mg a day
Coenzyme Q10 (Sanomit): 12 to 20 drops in the morning
Creatine (powder): 8 grams in the morning (since July 2025, before that 4 grams)
Lithium (lithium orotate): 20 mg elemental lithium in the morning
Selenium (sodium selenite): 200 µg in the morning
Zinc: 25 mg in the evening
Astaxanthin: 12 mg in the morning
TUDCA: 500 mg, 2-0-0
Nicotinamide riboside (TRU NIAGEN), a precursor of NAD: 300 mg in the morning
Urolithin A: 500 mg in the morning on an empty stomach (since spring 2026)
N-acetyl-L-leucine: 2.5 grams, more on this under Tanganil

For longevity

Spermidine: 6 mg in the morning
Taurine (powder): 2 grams in the morning
Glucosamine and chondroitin: 1,400 mg in the morning

For the muscles

L-citrulline DL-malate: 5 grams before strength training

Only at times

Ashwagandha
Methylene blue

Vitamin D3, omega-3 and lithium are especially important to me. I keep taking coenzyme Q10 and creatine despite the disappointing Parkinson's studies, because they matter for the energy of the cells and for the muscles.

A lab study from 2024 found that TUDCA, coenzyme Q10 and creatine together protected nerve cells better than each one alone (Frontiers in Neuroscience). This has not been tested in humans.

My target blood levels

These values serve as a guide for me. They come from my own research and are in part stricter than the usual lab limits. Please discuss your own target levels with your doctor.

Vitamin D3: optimal 40 to 60 ng/ml (100 to 150 nmol/l). From about 160 ng/ml (400 nmol/l), vitamin D becomes toxic.
Lithium: 25 to 300 µg/l in whole blood.
Omega-3 index: above 8 percent. The ratio of omega-6 to omega-3 between 1:1 and 2.5:1. My value was clearly too low at first and is in the target range after the adjustment.
Magnesium: have it measured in whole blood, which tells you more than serum.
Selenium: Too much selenium can damage the nerves. The European Food Safety Authority has set the upper limit for adults at 255 µg a day, including food. My neurologist specifically pointed this out to me. If you take selenium, you should have your level checked regularly.

Which magnesium?

Magnesium oxide: hardly absorbed, usually a cheap filler. Not recommended.
Magnesium citrate: quickly and readily available to the body, good for muscle cramps, mildly laxative.
Magnesium glycinate: good for sleep and inner calm, not laxative, so good for the evening.
Magnesium taurate: good for the heart and nerves.
Magnesium L-threonate: gets into the brain especially well.

A combination of citrate and glycinate often makes sense.

Effort and costs

The costs depend a lot on how much you take and can add up to several hundred euros a year. In Germany, health insurers only pay when a deficiency has been proven.
