There is currently a bottle of 60 gummies being sold as a Loss Belly Fat Product sponsored by Shark Tank for $70 a bottle and more, although Amazon has them for less.  The main ingredient is Apple Cider Vinegar.  You can buy 32 ounces of Organic Apple Cider Vinegar for $6 and there are 32 servings of 1 tablespoon in a bottle.

The Gummies come in different varieties.  Some have Beet Root Juice, B6, B12 or Calcium and Magnesium, etc.  The main ingredient they all are pushing is Apple Cider Vinegar, promising, weight management control, fat burning for fuel, reduces appetite.

Apple cider vinegar is made by fermenting the sugar from apples. This turns them into acetic acid, which is a main active ingredient in vinegar and may be responsible for its health benefits.

The main substance in apple cider vinegar — acetic acid — can kill harmful bacteria or prevent them from multiplying. It has a history of use as a disinfectant and natural preservative.  You can pour it on wounds to disinfect, pour on toenail fungus to kill it, it is amazing stuff.

Several human studies show that vinegar can increase feelings of fullness. This can lead to eating fewer calories and losing weight.

For example, according to one study, taking vinegar along with a high carb meal led to increased feelings of fullness, causing participants to eat 200–275 fewer calories throughout the rest of the day (Study 1, Study 2).

Furthermore, a study in 175 people with obesity showed that daily apple cider vinegar consumption led to reduced belly fat and weight loss (Study 3):

taking 1 tablespoon (15 mL) led to a loss of 2.6 pounds (1.2 kg)
taking 2 tablespoons (30 mL) led to a loss of 3.7 pounds (1.7 kg)

Over 3 months of time.

My point is that while taking a tablespoon of vinegar a day will have some good effects for you, don’t buy gummies on the click bait.  Always look at what they are selling you to lose weight.  There isn’t any fast quick easy solution or we would all be thin.
