Glycine

Short answer

We found no documented interaction between DIM and Glycine in the sources below. That isn't proof the combination is right for you: check each one's cautions, and ask your pharmacist if you take medication.

DIM (diindolylmethane)

What it is: A compound formed from vegetables like broccoli and cabbage, sold for estrogen balance.

What the research says: It changes how estrogen is broken down, and lab studies suggest anticancer effects, but human data are limited. There's no evidence for 'detox' claims.

Cautions

  • Not for pregnancy, trying to conceive or breastfeeding, because of possible hormone effects.
  • Rare reports include vision problems after very high use, and rash.

Medicines to check

  • Birth control pills: check with a clinician first
  • Many prescription drugs processed by the liver: DIM may make them less effective

Glycine

What it is: An amino acid the body makes; it's a building block of creatine, glutathione and collagen.

What the research says: Some studies suggest it may improve sleep quality and recovery, but reviews say more good human trials are needed.

Cautions

  • No major safety concerns are reported at supplement doses; human research is limited.

Medicines to check

  • Talk to your clinician if you take any medicine

Balancing dosages across multiple different bottles is risky, inefficient, and expensive. Glycine is already lab-dosed and delivered daily in our Stress Pack — one less bottle to manage.
