The final stretch of your summer internship is here. You’ve gotten into the rhythm, learned the tools, and figured out where the coffee is, but now it’s time to shift from settling in to standing out. Whether you’re aiming for a return offer, a killer reference, or just want to walk away feeling proud of your work, how you finish is just as important as how you started. 

This is the moment to sharpen your focus, fine-tune your routine, and show up like someone who belongs. In other words, it’s time to show up not just as an intern, but as a future hire. From the way you work to the tools that support you, a few smart moves can make all the difference. This list features 13 game-changing essentials (from mindset help to muscle recovery) that’ll help you wrap your internship like a pro.

1. Give Your Cellular Health a Boost With Fatty15

The days left in your summer internship program are numbered, which is why it’s more important than ever to make sure you’re caring for your overall wellness. With Fatty15’s C15:0 supplement, you can boost your cellular health and finish out your time feeling as energized and alert as possible.

As you might have guessed, cellular health refers to how well your cells are functioning overall. Given that cells are susceptible to oxidative damage, they naturally become more fragile and break down over time. When this happens, the metabolism slows, the immune system becomes unbalanced, and waste buildup occurs in the cells. Although this is an inevitable process, there are things you can do to help your cells resist the effects of oxidative stress and stay resilient.

One strategy involves incorporating C15:0, an essential fatty acid, into your diet. Although there are ways to get sufficient amounts of this fat from your food, the move toward plant-based eating has made this difficult. That’s why the revolutionary supplement from Fatty15 is a game-changer. Taking this supplement daily can improve your immune, metabolic, and red blood cell health as well as your liver fitness, so you can end your internship feeling your best.

2. Stay Comfy in Mac Duggal's Casual Dresses

Dressing for your internship can be tricky, especially when you're balancing office dress codes, summer heat, and back-to-back meetings. Mac Duggal’s casual dresses make it easy to look put-together without feeling overdressed or uncomfortable.

This collection includes options with flattering silhouettes that can transition seamlessly from morning coffee runs to afternoon presentations. You get all the formality of professional attire with the ease of something you actually want to wear. With these dresses, you can leave behind stiff blazers and awkward hemlines.

If you’re heading into your final weeks and want to make a lasting impression, showing up polished is key. Mac Duggal gives you that effortless, work-appropriate style that says, “Yes, I belong here.”

3. Seek Out PMS Relief With FLO From O Positiv

There’s no reason your period and PMS symptoms should negatively affect the end of your internship experience. To make sure they don’t, consider incorporating the FLO PMS relief vitamins from O Positiv into your wellness routine. These vitamins are packed with powerful natural ingredients that help uncomfortable PMS symptoms like period breakouts, hormonal bloating, cramps, and mood swings.

For less than $1 a day, you can experience period relief that’s sugar-free and scientifically designed for women’s needs during this time of the month. For example, one of the ingredients in FLO is dong quai, which has been shown to soothe the feeling of menstrual cramps. Another superstar ingredient is chasteberry, which can help ease the emotional swings that often come with PMS.

This is the product for you if you experience bloating with your period, mood swings, or cramping. Keep in mind that it takes about two full menstrual cycles to feel the full results, and prepare for your last month at work with ease.

4. Keep Cool and Confident With Salt & Stone’s Aluminum Free Deodorants

Nerves? Big presentations? Endless commutes? You need a deodorant that holds up without harsh ingredients. Salt & Stone’s aluminum free deodorants check all the boxes. They are effective, gentle, and made with ingredients that actually work.

11. Replace the Crash With Everyday Dose’s Mushroom Coffee
