Gut health

gives my mind at ease to take additional pre and post probiotics for gut health. At times when feeling a bit backed up these may help to release

Good, But Sweet

I liked the gummy format and found the flavor pleasant, although they were a little sweeter than I expected. They’re certainly easier to take than traditional probiotic capsules, and I appreciate that they’re designed with teens in mind. Overall, a convenient option, but I’d prefer a less sweet taste.

Easy Daily Probiotic

These probiotics are really easy to incorporate into a teen’s daily routine. The gummies have a pleasant flavor and texture, which makes them much more appealing than swallowing a capsule. I also like that they’re specifically formulated for teens. Overall, a convenient option that’s easy to stay consistent with.

Seems unnecessary for teens/kids

These are fine magnesium gummies. My kids don't really need these so I mostly just bought because of the Social Nature promotion. I like the packaging. In general I don't think kids need probiotic supplements unless they have a medical issue.

The overall experience has been positive, and it’s a convenient option for teens who want to include a probiotic in their routine. Definitely a product I’d consider buying again.

I love Social Nature. It has changed the way that I shop and the products that I buy. Things that I would have walked right past, I now consume on a regular basis. I make healthier and more conscious choices.

Almost all of the products I have been given the opportunity to try are products I've never heard of or would have bought. Now that I have tried these products, I have found new items that I will continue to buy for myself and my family. The website is so easy to use, and you get your cash back within a day or two of submitting the receipt! I love Social Nature!
