When to take it
There's no strong evidence that one time of day is better. Choose a time you'll remember daily. Taking garlic with food may reduce stomach upset for some people.
The VitalFlush dose
The seller's directions are a few drops under the tongue once a day, held for about 10 seconds. The exact drop count and mg of garlic per serve aren't published, so you can't directly compare it with doses used in research.
