Supplement stack checker

This checker is a fixed table of pairs that the page was coded with. It is not a drug-interaction database, not an FDA listing, and not a review of your medications. You tick ingredients. If two of them are marked avoid or caution in that table, the page prints the note that was stored with the row. If the table has no mark, it says it found no known interaction in this list. Absence from the list is not evidence of safety.

The pairs the table actually flags

Yohimbine is marked avoid with caffeine and with a generic pre-workout, and the stored note calls it a cardiovascular stimulant that should not be combined with caffeine. Caffeine's own row repeats that avoid. Citrulline is marked caution with arginine, with a note that citrulline is the one the page prefers for nitric oxide. Creatine, whey, beta-alanine, zinc, magnesium, and vitamin D are marked safe with each other in this table. Beta-alanine's note only mentions the harmless tingling called paresthesia. Magnesium's note says to take it at night. Zinc's note says to take it with food. Vitamin D's note says to take it with a meal that contains fat. Those are the opinions baked into the buttons. They are not new trials.

What to do with a green result

A clear result means the two names were not on each other's avoid or caution arrays. It does not mean the doses are the ones in a position stand, and it does not mean the tub is free of undeclared stimulants. Read the Supplement Facts panel, and for anything you will be tested on, prefer a certification such as NSF Certified for Sport. The FDA health-fraud notices live at FDA health fraud and scams. Ingredient background for creatine, caffeine, and protein as food is on the supplements guide. If you take a prescription drug, a pharmacist beats this grid. The same buttons are on the tools hub.
