Your Vitamin D May Be FAKE (Try This Test)

I always recommend to take vitamin D3, not vitamin D2. It's not as potent. It's made synthetically. I would avoid it. And I would definitely avoid taking any synthetic vitamin D3. You want to get a natural source of vitamin D3. Many manufacturers, when they make their vitamin D, have hidden maltodextrin. Or they might put in glucose syrup. They

put the starch as a filler. They use it because it's a very cheap ingredient. And most companies that sell vitamin D3 use these fillers. There's a very simple way you can test this. You open up the capsule, mix it in some water, add a few drops of iodine, and if it turns dark

purple, suspect a starch. This is called the starch test. And you can detect hidden maltodextrin and other starches in your supplements. If it doesn't have it in there, it'll just turn yellow or just slightly clear.
