Supplements and Morning Coffee: Timing Iron, Zinc, Calcium, B Vitamins, and Vitamin D: Nutritionist Leyla Muedin explains that coffee (and tea) can interfere with nutrient absorption and digestion, so certain supplements shouldn’t be taken with morning coffee. Coffee’s tannins and polyphenols can significantly reduce non-heme iron absorption (decaf doesn’t prevent this), and similar binding issues may affect zinc; she recommends taking iron with water at least 1–2 hours away from coffee and pairing it with vitamin C. Because caffeine may increase urination, B vitamins (especially thiamine) may be lost more readily, so she suggests taking them with food but not with coffee. Vitamin D is best taken with a fat-containing meal (not washed down with coffee), and calcium supplements should be separated from coffee since caffeine can slightly increase calcium loss. She also notes interactions such as green tea reducing folate absorption, spinach oxalates limiting mineral absorption, phytates in bran/legumes reducing iron and zinc absorption, and calcium (milk or supplements) cutting iron absorption, emphasizing timing rather than eliminating these foods.

Natalie Ochoa, president of Jigsaw Health, details widespread magnesium insufficiency and why it occurs (soil depletion, low plant intake/processed foods, stress-related loss, aging, and medication effects including diuretics and proton pump inhibitors). They discuss the poor reliability of standard serum magnesium testing, the limitations of RBC magnesium testing, and using symptoms such as cramps, twitches, constipation, fatigue, and sleep trouble as clues. Ochoa explains Jigsaw’s sustained-release magnesium malate (MagSRT) designed to reduce GI side effects and how to read labels for elemental magnesium, with typical intake around 500 mg/day. She reviews the 2018 placebo-controlled Scottsdale Magnesium Study (91 participants) showing increases in RBC and serum magnesium and reduced deficiency symptoms, and a Korean study linking higher magnesium intake to less sarcopenia and lower CRP. They also cover MagSoothe (magnesium glycinate) and an Oura Ring-based sleep trial reporting reduced perceived stress and improved sleep quality, plus mention Jigsaw’s potassium drink, electrolyte product, and cod liver oil.
