"Within medicine there is a growing body of evidence that suggests that our mind, gut, and skin communicate in important ways about our health," board-certified dermatologist Caroline Robinson tells Bazaar.com.

Here, we've pulled together the best hair, skin, and nail vitamins worth trying—from tasty gummies to mixable powders. Plus, more information on the topic, straight from Robinson and New York-based dermatologist Dendy Engelman.

Pros
Single-use packets- Sugar-free
Cons
For a vitamin boost, Engelman enjoys drinking collagen by mixing a powder, like this option from Love Wellness, in her daily beverages. "I like it in powder form. It is easy to mix into something you are already drinking," she says, adding that "if it is tasteless, then you don’t even know you are drinking something super healthy for you."

Magnesium Glycinate is everywhere as of late, and for good reason. Not only is it an absorbable form of magnesium (meaning it's easier on the stomach than other supplements), but it can help decrease anxiety, improve sleep, and promote muscle and bone health. We love this one from Vimergy because it also contains an anti-inflammatory blend of ginger and turmeric root.
One satisfied customer writes:
"This is the Best Magnesium I've found! I use it in combo with Melatonin before I sleep and it works great! ( And no tummy issues like I had with other magnesium :)" – Bernadette

Can using a supplement actually fortify your hair, skin, and nails?
According to Engelman, supplements can "definitely" be of service. "They are a great way to enhance your skincare, hair care, and other regimens because they can provide vital vitamins and minerals that our body needs to have healthy skin cells or hair follicles," says the derm. "As we age, many of our natural occurring proteins and vitamins deplete and supplements help to replenish this loss and support the building blocks of our body."
What are the best ingredients for hair, skin, and nail vitamins?
Collagen isn't just a beauty buzzword. "As we age, production of collagen, a naturally occurring protein in the body, decreases," says Engelman. "I find that taking collagen supplements to combat the effects of aging can be extremely beneficial. This helps to increase protein support, which can positively impact the skin, hair and nails."
Vitamins and supplements aren't regulated by the FDA in the same way drugs are, so one thing Engelman stresses is to look at the brand's clinical studies. "Not all proteins are sourced or tested in labs that are up to medical standards," she says. Therefore, "A brand should be transparent in where and how they source their proteins and vitamins."

When can I expect to see results?
"The timeline of seeing the benefits from supplements differs based on many factors," says Engelman. "Depending on the strength or dose of the supplement, the frequency of consumption, and the individual themselves, it can take anywhere from two to six months to start seeing results." However, if you don't see results after six months, don't get too worried: According to Robinson, it can take even longer. Plus, she adds, "Consistency with these changes matters more than anything."
