No, those TikTok-famous collagen gummies aren't a healthy meal replacement

TikTok, the addicting short-form video app akin to the dearly departed Vine, has its pros and cons. The latest trend on health TikTok is homemade gelatin gummies, which greatly resemble the gelatinized cockroach protein bars eaten by the Tailies in "Snowpiercer." Per Stephany Victoria — a holistic private chef, certified yoga instructor and fitness enthusiast — gelatin gummies promote "tighter skin, healthier hair, stronger nails, healthy gut, healthy joints, better quality sleep, stronger bones and a healthy heart." The gummies are also said to "help your digestion, support joint health, reduce inflammation and a great source of protein," according to holistic health and fitness enthusiast Jules Cassano. There's videos of influencers glorifying extreme weight loss, promoting restrictive diets and "healthifying" specific foods, like substituting bread for lettuce and French fries for carrots.
