My 16-month theanine self-experiment

I finished one bottle of Theanine for occasional use and went to order a different combo as it was unavailable. It is Theanine Serene with Relora which also includes Magnesium, GABA, Taurine, and Holy basil in two large tablets. Helps relax and ease falling asleep.

Another option may be a pain/stomach relief/sleep aid concoction we found :

1tsp ginger

1tsp turmeric

1tsp cinnamon

1tsp fine black pepper

500ml milk

Boil for 10 minutes. Drink one cup warm and save the other for another day.

If you're not careful and diligent, this is a recipe for liver damage from coumarin and heavy metal toxicity. You can take all those things safely but it requires knowledge and care.

Hey, ok I get it for coumarin but just out of curiosity, what can introduce heavy metals in this mix?

Turmeric and cinnamon are both notorious for lead contamination.

In many locations it's legal to sell consumables that have disgustingly high ppm of heavy metals as long as the recommended daily dose is small so that the absolute amount of heavy metals stays below a fixed threshold. Also many companies just flagrantly violate the regulatory levels.

Getting clean turmeric extract is possible by knowing which brand to trust. Natural Factors is trustworthy, they are transparent with heavy metal testing and have third-party validation in academic studies and by consumerlab.com. But even if it's clean, you would still need to manage this risk: https://www.ncbi.nlm.nih.gov/books/NBK548561

For cinnamon, avoiding coumarin is possible by making sure it's ceylon cinnamon. But I don't know of any brand selling ceylon cinnamon that I would also trust to have low heavy metal levels. The intersection of reliable brands and ceylon cinnamon sellers is a very sparse set.
