"Probiotics put good bacteria back into the body, and that helps you to digest, break down, and absorb nutrients in the small intestine," says celebrity holistic nutritionist and author Sally Pansing Kravich, MS, PhD. And, as we all know, gut health is not something to be overlooked.

"Omega-3 fatty acids are highly important, because it's a protector against all the radio currents we are bombarded with, and it's great for brain development," Kravich tells TotalBeauty. She also says that it helps curb other fat cravings, which is always a plus in our book.

"Having a good B50 or B100 will help feed your nervous system and help with stress," says Kravich. And when combined with fish oil, she says it can also help keep your hormones balanced.

Kravich says that vitamin D is also an essential nutrient that we need since we often aren't exposed to enough natural light. "Getting vitamin D is important for the synthesis of calcium and our structural health," she explains.

"Take calcium at night at bedtime in liquid or powdered capsule form," suggests Kravich. She elaborates that it acts like the best sleeping pill in the world (and we could all use a little help sleeping, no?). Plus, it can help with weight management, since it relaxes and helps you get into a deeper sleep, which in turn allows your body to repair itself.
