Master the biochemistry and clinical pathology of Niacin with our U01.01.076 Vitamin B3 question set. This practice collection covers high-yield medical topics including NAD+ and NADP+ as essential cofactors for redox reactions, glycolysis, and the HMP shunt. Learn to identify the classic "4 Ds" of Pellagra and the role of Tryptophan as a precursor. Designed for medical students, these free medical questions on mymedschool.org provide essential preparation for USMLE Step 1 and clinical nutrition exams.
So, I've been on the #TartCherryJuice kick for maybe a year now... I drink a little (maybe 4 ounces) before bedtime (followed by a turmeric tea chaser for inflammation. More about that in another post). The tart cherry juice has been helping my sleep (both quality and quantity), and I would highly recommend it over OTC drugs!
What Happens to Your Sleep When You Drink Tart Cherry Juice Before Bed
By Daphne Yao
Published on January 23, 2026
Highlights:
- You can drink tart cherry juice to improve your sleep due to its #melatonin and #tryptophan content.
- Drinking 8-12 ounces of tart cherry juice or 1-2 ounces of concentrate may help you sleep.
- Tart cherry juice may also help lower your blood pressure and improve your immune response.

Tryptophan, an essential amino acid, has been found to exist on #Bennu, a small #asteroid that swings by our #planet about every six years.
The discovery stems from an unprecedented sample collected by the OSIRIS-REx mission, which landed a #spacecraft on the asteroid in 2020, captured 121.6 grams of rocks and dust, and safely returned the cache to Earth in 2023.
Studying Bennu is important because its composition reflects that of the early solar system, giving scientists a glimpse into the beginnings of #life.
Finding tryptophan in the Bennu asteroid is a big deal, because #tryptophan is one of the more complex amino acids, and until now it had never been seen in any #meteorite or space sample.
The presence of tryptophan in an asteroid supports the idea that the recipe for life might not have begun only on Earth. Seeing it form naturally in space tells us that these ingredients were already being made out in the early Solar System. That would have made it easier for life to get started.
