So much better than the sugar version which has SOOOO much sugar it gave me heartburn. Yes, the sugar version is tasty like Tang, but that sugar gave me indigestion. The aspartame version was disgusting. This Stevia is awesome. Because it doesn’t have tons of sugar, you only need 2 heaping teaspoons instead of 2 tablespoons of the regular. I think it’s delicious and also has natural coloring, the sugar version has artificial dyes. I drink it everyday and my GI tract has never been happier. Only one small issue, this size container (~14 oz) is narrow, so buy the bigger bottle (23 or 34?) so you can reach in to scoop it easily. I have zero bloating or gas and sometimes take it more than once per day. It supposedly decreases appetite if taken before meals. It expands in your gut! Perfect. Just don’t take it within 2 hours of oral meds/vitamins as it can supposedly decrease gut absorption. Enjoy the results!!

Lower Cholesterol and Better Digestion, Even if the Taste Takes Getting Used To

Size: 2.32 Pound (Pack of 1), Style: New

I started using this fiber supplement after my doctor recommended it to help manage my cholesterol. I like that it’s plant-based and sugar-free, and it’s easy to mix into water. After taking it regularly, I’ve noticed a positive impact on my digestion, and I’m hopeful it will help with my cholesterol in the long run. The only thing is that the taste and texture aren’t quite what I expected — it’s a bit like protein powder. Still, the health benefits make it worth continuing
