Bought the capsules for myself. The day and night combination. Saw results after the 2nd month

- Djay T.

We have tried several different supplement brands, and Shiydf is by far the best tasting.

- Michelle R.

So far so good, two of my kids are taking these so we will see in 6 months if there is any change

- Brandi B.

My daughter Angela was doubtful to try shiydf but gave it a shot. We havent looked back since. After nearly 6 months, she has grown almost 3 inches. Apart from the obvious height gain, her overall demeanor and health have improved. Shes more energetic, and her posture has significantly improved, which her doctor also commented on during our last visit

- Elina M.

I see a real difference in my son’s height in a short period of time, unlike the other supplements we had tried in the past.
