How to Choose the Right Supplement When Your Energy and Immunity Need a Boost
Feeling tired, foggy, or just off? You’re not alone. Many people in Los Angeles deal with low energy, poor sleep, or frequent colds—and often wonder whether supplements can help. Three of the most commonly searched and asked-about nutrients are magnesium, vitamin D, and zinc. But what do they actually do, and how do you know which one you might need?
At Olympia Plaza Pharmacy, we help patients build smarter supplement routines that actually work. Here’s a breakdown of magnesium, vitamin D, and zinc—plus how to know when you might be low, and what to take to feel better fast.
Magnesium is involved in over 300 biochemical reactions in your body, including muscle relaxation, nerve function, and energy production. If you’re constantly stressed or struggling with sleep, a magnesium deficiency could be part of the problem.
Trouble falling or staying asleep
Muscle cramps or restless legs
Anxiety, irritability, or mood swings
Low energy despite sleeping enough
Headaches or migraines
Magnesium glycinate – gentle on the stomach, great for relaxation and sleep
Magnesium citrate – helpful for digestion and occasional constipation
Topical magnesium sprays – for muscle soreness and tension
Talk to our pharmacists to find the right form and dosage for your needs.
Even in sunny Los Angeles, vitamin D deficiency is surprisingly common—especially if you work indoors, wear sunscreen (as you should!), or have darker skin, which naturally blocks UV absorption.
Vitamin D supports your immune system, bones, and mood regulation. Low levels can leave you feeling tired, foggy, and more prone to illness.
Frequent colds or infections
Bone or joint discomfort
Fatigue and brain fog
Seasonal depression or mood dips
Hair thinning or loss
Vitamin D3 (cholecalciferol) – more effective than D2 for raising blood levels
Often combined with vitamin K2 to support bone and heart health
Available in gummies, softgels, and drops
We recommend getting your vitamin D levels checked with a blood test before taking high doses—ask our pharmacy team for more info.
Zinc is a trace mineral that plays a huge role in immune function, wound healing, and enzyme activity. It’s one of the most important supplements to have on hand when you’re feeling under the weather or trying to shorten the duration of a cold.
Frequent colds, sore throats, or slow recovery
Loss of taste or smell
White spots on nails
Slow wound healing
Low appetite
Zinc picolinate or gluconate – well-absorbed and gentle on the stomach
Zinc lozenges – helpful at the first sign of a cold
Zinc + vitamin C combos – great for immune system support year-round
Zinc works best in short bursts—taking too much long-term can lower copper levels and affect digestion, so ask us about safe dosing.
Every body is different, and the answer depends on your specific symptoms, lifestyle, and diet. Here’s a quick guide:
