In the realm of herbalism and nutrition, the synergy of certain herbs, vitamins, and minerals is well-documented. However, the less frequently discussed topic of what combinations to avoid is equally important. As an herbalist, I often receive inquiries regarding multivitamins and supplements, and my response is often to advise caution rather than recommendations. This article outlines 11 combinations of herbs, foods, vitamins, and minerals that should be avoided to prevent adverse effects and ensure optimal health.
1. Magnesium and Calcium: A Counterproductive Combo
While magnesium and calcium are frequently included in multivitamin supplements, they can negate each other’s benefits. Calcium should ideally be taken in the morning, while magnesium is best taken at night as it aids in sleep.
Tip: Magnesium can enhance relaxation and relieve muscle cramps, like Charlie horses. It is most effectively absorbed by the skin through topical applications, such as creams rather than oral supplements.
2. Potassium and Calcium: Competing for Absorption
When taken together, potassium and calcium compete for absorption in the intestines, which can lead to deficiencies. It is advisable to space these minerals out by at least two hours.
Tip: Athletes in humid environments are particularly prone to potassium depletion. Consuming potassium-rich foods like bananas or kiwis before exercise can mitigate cramps.
3. Zinc and Copper: A Risk of Deficiency
According to the Mayo Clinic, approximately 30% of Americans are copper deficient, which is crucial for iron metabolism, nervous system function, and bone health. However, zinc interferes with copper absorption. Long-term high doses of zinc (50 mg or more daily for 10 weeks or longer) can lead to copper deficiency.
Tip: If consuming copper-rich foods or supplements, wait at least two hours before taking zinc to avoid absorption issues.
4. Vitamins A, D, E, and K: Optimal Absorption Requires Spacing
These fat-soluble vitamins are often found together in multivitamins, but for optimal absorption, they should be spaced out. Especially if a deficiency is present.
Tip: Many individuals are deficient in vitamin K; therefore, it is beneficial to take a vitamin K supplement or consume leafy greens at least two hours apart from other fat-soluble vitamins. Unless it is paired with vitamin D3, as together they work for maximum absorption.
5. Iron and Curcumin/Turmeric: Inhibited Absorption
Iron is essential for oxygen transport in the body; however, its absorption is significantly reduced when taken with green tea, black tea, turmeric, or curcumin supplements.
Tip: Waiting at least three hours between taking iron and these substances is recommended for optimal absorption.
6. Red Yeast Rice and Niacin: Liver Damage Risk
Both red yeast rice and niacin are effective for managing cholesterol levels, but taking them together can increase the risk of liver damage without enhancing cholesterol-lowering benefits.
Tip: Consult a healthcare provider before combining these supplements, especially if you are on cholesterol-lowering medications.
7. St. John’s Wort and Antidepressants: A Dangerous Interaction
St. John’s Wort is known to increase serotonin levels, but combining it with antidepressants categorized as SSRIs can lead to severe side effects, including fever, confusion, and seizures.
Tip: DO NOT mix St. John’s Wort with these antidepressants under any circumstances.
8. CoQ10 and Diabetes Medications: A Serious Concern
CoQ10 is beneficial for heart health but should not be taken with diabetes medications, as it may significantly lower blood sugar and blood pressure. This combination can elevate the risk of falls and injuries.
Tip: DO NOT mix CoQ10 with diabetes medications to avoid serious health risks.
9. Antibiotics and Iron: Ineffective Treatment
If prescribed antibiotics, it is crucial to discontinue all iron supplements, as iron can inhibit the effectiveness of antibiotics.
Tip: Iron supplements may be resumed one to two weeks after completing antibiotic treatment, but consult a healthcare provider first.
10. Blood Thinners and Various Supplements: A Cautionary List
Supplements such as fish oil, ginger, ginkgo biloba, garlic, feverfew, vitamin E, vitamin K, leafy green vegetables, and white willow bark all possess blood-thinning properties. Taking these together with blood thinners can lead to excessive bleeding and other complications.
Tip: Always inform your healthcare provider about dietary changes and supplements you are taking to avoid adverse interactions.
11. Blood Thinners and Echinacea: Increased Stroke Risk
Echinacea, known for its immune-boosting properties, should not be taken with blood thinners, as it can reduce their effectiveness and increase the risk of stroke.
Tip: Individuals with autoimmune diseases should avoid Echinacea, as it can provoke an overactive immune response.
It is essential to recognize that “natural” does not necessarily equate to “safe.” Whether using supplements, food, or pharmaceuticals derived from natural sources, it is imperative to exercise caution. Awareness of these potentially harmful combinations can help you make informed decisions on your wellness journey. Prioritizing your health involves understanding how different substances interact within your body.
For personalized advice regarding supplement use and interactions, consult a healthcare professional or nutrition specialist.
