But vitamin B12 doesn\u2019t actually create energy. Instead, your body needs it to convert the food you eat into usable energy. That means a B12 supplement may support energy levels as part of an overall approach that also includes a balanced diet.\n<\/p>\n

Don’t combine magnesium with OTC sleep aids \ud83d\ude34 <\/p>\n Magnesium is a popular supplement for sleep, but doctors say you should avoid combining it with \u00a0over-the-counter sleep aids<\/a>. Taking magnesium and sleep aids together can intensify drowsiness, leaving you dizzy or fatigued the next day.\n<\/p>\n It\u2019s best to use only one sleep aid at a time. If you have persistent sleep problems, talk to your healthcare provider about proper treatment.\n<\/p>\n 3. These popular supplements could disrupt your sleep \ud83d\udca4 <\/p>\n While some supplements are marketed as sleep miracles, others can interfere with sleep if you\u2019re not careful about timing. Some common ones include vitamins D, C, and B12, calcium, coenzyme Q10, and any supplement that contains caffeine<\/a>.\n<\/p>\n Some of these may be necessary to treat or prevent a deficiency, so taking them earlier in the day can help protect your sleep. If others are optional and you suspect they\u2019re disrupting your rest, consider pausing them to see whether your sleep improves.\n<\/p>\n 4. Do you get extra benefits from combining magnesium and fish oil? \ud83d\udc85 <\/p>\n While magnesium and fish oil supplements may offer modest benefits for improving blood pressure, the evidence is limited on whether combining them provides extra protection.\n<\/p>\n In an explainer<\/a>, a registered dietitian breaks down how each supplement works, what the data shows, and who might (and might not) benefit from adding them to their routine.\n<\/p>\n 5. Time your multivitamin to reduce stomach upset \u23f0 <\/p>\n It\u2019s common advice to take a daily multivitamin first thing in the morning on an empty stomach, but swallowing it with just coffee can irritate your stomach. Taking your vitamin with breakfast is often a better option<\/a>.\n<\/p>\n Pairing your supplement with your first meal can help reduce gastrointestinal side effects and usually won\u2019t interfere with absorption. In fact, your body may actually absorb it better. You\u2019ll also avoid taking certain vitamins too close to bedtime, which can interfere with sleep.<\/p>\n![\"Healthcare](\"https:\/\/www.newsbeep.com\/ca\/wp-content\/uploads\/2025\/09\/norman-dd595cddde654266bd40199db77e316f.jpg\")
