1. Excessive vitamin K/potassium
While potassium is essential for various bodily functions (including heart health) and a supplement can be helpful and perfectly safe in many instances, excessive levels can be detrimental—especially for those taking certain medications. "ACE (angiotensin-converting enzyme) inhibitors and angiotensin II receptor blockers (ARBs), approved to treat high blood pressure, may increase blood potassium levels by blocking aldosterone. Aldosterone is a hormone that is responsible for removing potassium through the urine," Ngo-Hamilton says, noting that "If you take any of these medications, you should avoid potassium supplements unless your doctor advises you to take them." Noted!
2. Excessive Vitamin D and Calcium
Deficiencies in vitamin D and calcium are prevalent, often stemming from inadequate sun exposure. Consequently, many turn to supplements to meet their nutritional needs. However, excessive intake of these nutrients may heighten the risk of cardiovascular diseases. HaVy Ngo-Hamilton warns, "Too much vitamin D and calcium can increase the risk of cardiovascular diseases, especially if these supplements are purchased from non-credible sources." Before incorporating these supplements into your routine, it's crucial to consult with your healthcare provider and assess your blood levels to determine if supplementation is necessary. When in doubt, getting these nutrients straight from the foods you eat is your best bet.
3. Omega-3 Supplements (When Taken With Certain Medications)
Omega-3 fatty acids are renowned for their cardiovascular benefits, but their interaction with certain medications warrants caution. HaVy Ngo-Hamilton highlights the potential interaction with platelets, crucial blood cells involved in clotting. "If you are taking clopidogrel (Plavix) or Coumadin (warfarin), you should talk to your doctor before taking omega-3 supplements." It's essential to exercise caution, especially when combining supplements with prescription medications.
4. Vitamin E (When Taken With Beta-Blockers)
Often touted for its antioxidant properties, vitamin E is another supplement that requires careful consideration—particularly for individuals on beta-blockers for high blood pressure management. HaVy Ngo-Hamilton explains, "Vitamin E is believed to interact with beta-blockers, affecting how the medication is absorbed in the body." As such, it's important to discuss potential interactions with your healthcare provider before supplementing with vitamin E.
Bottom line
Ultimately, while supplements can play a valuable role in supporting overall health, they also come with risks. Consulting with healthcare professionals and prioritizing evidence-based supplementation practices are crucial steps to take. Remember, your heart deserves the best care—so approach supplementation with caution and informed decision-making.
