Zinc is a supplement Tim Liu, CSCS, an online fitness and nutrition coach and member of our Medical Expert Board, takes, because believe it or not, many individuals are zinc-deficient. In fact, according to March 2022 research published in Frontiers in Nutrition, zinc deficiency impacts approximately two billion individuals worldwide.

If you're wondering what makes zinc so beneficial, Liu explains it gives your testosterone and immune system a solid boost. Incorporating a zinc supplement into your diet can help you ward off illnesses. Some research even suggests that zinc can help reduce the amount of time you deal with cold symptoms.

Magnesium is another supplement Liu regularly works into his diet; it's also something many of us are deficient in. If you haven't heard of the pros associated with this nutrient, it's time to get familiar. Foods like beans, seeds, nuts, fish, avocados, dark leafy greens, and bananas are all stellar sources of magnesium. You can also reap the benefits of magnesium in supplement form.

Protein Powder

"The benefits of protein powder on muscle repair, muscle growth, and recovery are scientifically proven," says Anthony J. Yeung, CSCS, a fitness expert and the founder of GroomBuilder. He personally recommends preparing a post-workout shake to help with the recovery process, even if you're trying to slim down. "If you need extra protein in your diet, have a shake daily, but don't rely on them," he says. "Focus on getting most of your protein from real food. Nowadays, there are many varieties from whey to hemp to rice so see what feels best for you."


omega 3

There are plenty of Omega-3 supplements on the market. But what exactly are Omega-3 fatty acids and their benefits? According to Yeung, "These have a powerful anti-inflammatory effect and have a lot of scientific support behind their benefits for fat loss, heart health, joint health, and more. Whether it's fish, krill, flax, etc., a little goes a long way." Omega-3s also offer hormonal and mood-boosting benefits.

Last but not least, Yeung takes probiotics but stresses "the jury is still out" on them. You can find probiotics in yogurt, fermented foods like kimchi and kombucha, and dietary supplements. If you've browsed the vitamin aisle at your local health or food store, you're likely quite familiar with probiotics. "These are healthy gut bacteria that can aid in digestion," Yeung adds. "In certain cases, [taking probiotics] can help. If you're curious, start with a smaller number of CFUs and see how it feels."
