Experts caution that taking supplements without prior blood tests can lead to health issues, emphasizing the importance of individualized assessments for nutrient needs.
Supplements have become a daily wellness habit for many Americans, but experts warn that more isn’t always better. Common nutritional supplements include zinc for immune function, ashwagandha for stress relief, fish oil for heart health, and magnesium for improved sleep. These products have gained popularity, especially on social media platforms.
In an interview with Fox News Digital, Jim LaValle, a clinical pharmacist and metabolic medicine expert based in Texas, emphasized the need for balance when it comes to supplements, particularly in relation to other medications and existing medical conditions. “I’ve never met a supplement I didn’t like under the right circumstances,” he stated. “There’s some evidence around what it’s doing in the body.”
While certain nutrients can be beneficial, LaValle cautioned that overdoing it can be “problematic.” He noted that many individuals take a variety of supplements, sometimes stacking them with peptides, leading to a regimen that can include as many as 18 different products. “It’s important to first assess what the body needs from an individualized approach,” he advised.
For instance, low magnesium levels have been linked to the development of metabolic syndrome. In such cases, a magnesium supplement could help balance nutrient levels. LaValle pointed out that many people assume a healthy diet will provide all necessary nutrients, but questioned whether the foods they choose are indeed rich in those essential elements.
LaValle recommends using supplements to address specific needs, starting with a blood test to identify any deficiencies. He noted that low iron and ferritin levels are common among those who complain of fatigue. However, many individuals may turn to supplements like ashwagandha or rhodiola in an attempt to boost their energy without first checking their iron levels. “They’re buying some kind of stimulant adaptogen to try to get their energy up,” he explained. “That’s pretty basic—you’re low in iron, and you never got a blood test.”
According to LaValle, the number of biomarkers measured is less important than how well the results are interpreted. After appropriate blood testing, the results can help identify “functional highs and lows” and establish specific health goals. “If you’re somebody who has a goal to get out there and get after it and do a Hyrox or an LT Games or a Tough Mudder, there could be supplements that would help improve your performance or reduce your risk of injury,” he said. “It doesn’t mean you have to take them all the time.”
LaValle reiterated the ease with which individuals can “overdo it,” particularly given the influence of online health and wellness advice. “When people are getting barraged with marketing between social media and friends telling them, ‘I did this and it worked,’ they’ll lean in and go, ‘Hey, if two is good, four is better, and why not do 10?’”
One example LaValle provided is the role of zinc in the body. Low levels of this essential nutrient can disrupt key functions, as zinc is crucial for immune health, cell growth, and metabolism. However, excessive zinc supplementation can lead to digestive distress and copper deficiency, which may result in anemia and other neurological problems. “So having low zinc is not good, but you can overdo zinc,” LaValle cautioned. “You can overdo vitamin A. You can overdo vitamin D easily, and that could be potentially toxic if you’re taking too much of it.”
Experts advise that individuals should consult with a doctor or pharmacist before starting or combining supplements, especially if they are taking prescription medications or have underlying health conditions. Blood testing may also be appropriate prior to supplementing certain nutrients, according to health professionals.
In summary, while supplements can play a role in enhancing health, it is crucial to approach their use thoughtfully and based on individual needs, ideally starting with a blood test to inform decisions.
According to Fox News Digital, understanding one’s specific nutrient requirements can prevent potential health risks associated with improper supplementation.
