Molly Sims reveals one of the secrets to maintaining her incredible bikini body trends now

Molly Sims has an incredible bikini body as she heads toward the big 50.

And on Wednesday the Vegas actress revealed one of the tricks she uses to look so svelte and shapely.

The 49-year-old star shared on her Insta Stories that she drinks bone broth.

The looker - who was seen in Mexico last week - even showed her followers that she pours the brown liquid into a white mug with a red heart on front.

Over the photo of the mug of broth she wrote: 'Anti-ageing, good for digestions and gut, helps my joints after workouts, better sleep... this has been game changing for me.' 

According to webmd, 'Bone broth, sometimes called stock, is liquid made from boiling animal bones and connective tissue. Chefs use stock as a base for soups, sauces, and gravies. Some people drink it on its own.

'People have been making bone broth since the beginning of humankind. Anthropologists think people drank liquid infused with bones and other animal parts as early as prehistoric times.

'People all over the planet make bone broth from the animals that live nearby. The popular Japanese ramen dish tonkatsu — “pork bone broth” in English — is one example.'

It was also shared that most bone broth has at least trace amounts of several nutrients. 

'Adding vegetables to bone broth can also significantly enhance its nutritional benefits.'

It was also claimed it can help with weight management, hydration, sleep, nutrition.

This comes after she took to Instagram to show off her figure while on a beach vacation in Mexico.

The former Old Navy model was making the most of a tiny black string bikini that highlighted her trim tummy.

The 49-year-old star said she was on a Girls Trip with her longtime girlfriends.
