In a recent interview with Fox News Digital, Texas‑based clinical pharmacist and metabolic‑medicine specialist Jim LaValle cautioned residents against the popular habit of “stacking” numerous dietary supplements without first confirming a genuine need through blood testing.
Why a one‑size‑fits‑all approach falls short
LaValle explained that while supplements such as zinc for immune health, ashwagandha for stress relief, fish oil for heart support, and magnesium for sleep can be beneficial, indiscriminately taking them all may be “problematic.” He noted, “A lot of people take one of everything and then stack peptides on top of it — and then they’re going and doing 18 different things.” The expert emphasized that each individual’s biochemistry is unique, and supplement regimens should reflect actual deficiencies rather than trends seen on social media.
Blood work as the first step
According to LaValle, the most reliable way to determine which nutrients are lacking is a comprehensive blood panel. “Low iron and ferritin are common among people complaining of fatigue,” he said, adding that many turn to adaptogens like ashwagandha or rhodiola without first confirming an iron shortfall. “They’re buying some kind of stimulant adaptogen to try to get their energy up. That’s pretty basic — you’re low in iron, and you never got a blood test,” he warned.
He also highlighted that low magnesium levels have been linked to metabolic syndrome, suggesting that a targeted magnesium supplement could help balance those levels when a deficiency is confirmed.
Risks of over‑supplementation
LaValle stressed that excess intake can lead to adverse effects. For example, while zinc is essential for immune function, cell growth, and metabolism, too much can cause digestive upset and even copper deficiency, which may result in anemia and neurological issues. Similarly, excessive vitamin A or vitamin D can become toxic if not monitored.
“You can overdo zinc, you can overdo vitamin A, you can overdo vitamin D easily,” LaValle said. “That could be potentially toxic if you’re taking too much of it.”
Balancing supplements with medications and health conditions
The pharmacist advised that anyone taking prescription medications or managing chronic health conditions should consult a doctor or pharmacist before adding new supplements. He noted that the number of biomarkers measured is less important than how well the results are interpreted and applied to specific health goals.
LaValle also acknowledged that athletes or fitness enthusiasts may benefit from certain supplements to improve performance or reduce injury risk, but he cautioned that this does not mean they need to be taken continuously.
Practical takeaways for Texans
For readers seeking to optimize their wellness routine, LaValle recommends the following steps:
- Schedule a comprehensive blood test to identify any nutrient deficiencies.
- Discuss the results with a qualified health professional before starting any supplement.
- Target supplements to address specific, documented gaps rather than using a blanket approach.
- Monitor for potential side effects, especially when taking fat‑soluble vitamins like A and D.
By taking a measured, individualized approach, Texans can avoid the pitfalls of over‑supplementation while still reaping the benefits of nutrients that truly support their health.
