Your liver converts it to 25-hydroxyvitamin D, the form a blood test measures, and your kidneys turn that into calcitriol, the active form that helps your gut absorb calcium (from the \u003ca href=\"https:\/\/ods.od.nih.gov\/factsheets\/VitaminD-HealthProfessional\/\"\u003eNIH fact sheet on how vitamin D is activated and how much adults need\u003c\/a\u003e).

In a 12-week randomized, placebo-controlled trial, 335 healthy women aged 20 to 64 took a placebo or 15 mcg a day of D2 or D3, in juice or a biscuit, through a UK winter. Blood vitamin D in the D3 groups rose about 15 to 17 nmol\/L more than in the D2 groups (\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/28679555\/\"\u003ea daily-dose trial comparing D2 and D3\u003c\/a\u003e). It's one trial, in women, using fortified food at a lower dose than ours, so read it as direction, not a number.\u003c\/p\u003e\n\u003cp\u003eHow much does a daily dose move blood levels? In a winter study of 67 healthy men in Omaha given 0, 25, 125 or 250 mcg of D3 a day for about 20 weeks, blood 25-hydroxyvitamin D settled in direct proportion to the dose, about 0.7 nmol\/L higher for every extra microgram a day (\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/12499343\/\"\u003ea dose-response study of daily vitamin D3\u003c\/a\u003e). The response to vitamin D also varies widely from person to person (the dietary fat study below opens with that point), so the only way to know your own level is a 25-hydroxyvitamin D blood test.\u003c\/p\u003e\n\u003ch3\u003eVitamin D and calcium\u003c\/h3\u003e\n\u003cp\u003eIn a Creighton University study, people absorbed 65% more calcium from a 500 mg dose when their blood vitamin D averaged about 86 nmol\/L than when it averaged about 50 nmol\/L, and both numbers sit inside the normal reference range (\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/12672710\/\"\u003ea study of calcium absorption at two vitamin D levels\u003c\/a\u003e).

The \"1200 GDU\/g\" on the label is a strength rating: GDU means gelatin digesting units, a measure of protein-digesting activity. At 200 mg per capsule, that works out to about 240 GDU.\u003c\/p\u003e\n\u003cp\u003eIn a study of 19 healthy men taking 3 grams of bromelain a day (15 times the amount here), small amounts of intact bromelain showed up in the blood and kept part of its enzyme activity (\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/9252520\/\"\u003ea study of bromelain absorption in healthy men\u003c\/a\u003e). So some bromelain makes it through digestion in one piece.

In a randomized study of 50 healthy older adults who took a single 50,000 IU dose of D3 with breakfast, peak blood vitamin D3 was 32% higher when the breakfast contained fat than when it was fat-free, and the mix of fats in the meal didn't change the result (\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/25441954\/\"\u003ea study of dietary fat and vitamin D3 absorption\u003c\/a\u003e).

In Good C, the vitamin C comes as calcium poly ascorbate, a buffered form in which vitamin C is bound to calcium as a mineral salt (a calcium ascorbate) instead of being a free acid. That's why the bottle says acid free, and it's where the 57 mg of calcium on the panel comes from. That calcium is a small extra (4% of the Daily Value), not a calcium supplement.\u003c\/p\u003e\n\u003cp\u003eDoes the form change anything inside your body? Early evidence says possibly, a little. \u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/39408325\/\"\u003eA 2024 preliminary study comparing calcium ascorbate with ascorbic acid\u003c\/a\u003e ran two small crossover trials in 93 healthy adults, one at 250 mg and one at 500 mg, giving each person a single dose of both forms. At 250 mg there were no differences. At 500 mg, compared with ascorbic acid, calcium ascorbate raised blood levels of dehydroascorbic acid (an oxidized form of vitamin C), increased neutrophil activity over the first 8 hours, and was linked to more natural killer cells.† It tested single doses of calcium ascorbate in general, not this exact ingredient, so read it as an early signal rather than proof.\u003c\/p\u003e\n\u003ch3\u003eHow much your body actually absorbs\u003c\/h3\u003e\n\u003cp\u003eYour gut absorbs vitamin C well in moderate amounts and less efficiently in big single doses.

A single 200 mg dose was completely absorbed. At single doses of 500 mg and higher, the share absorbed dropped and the extra was passed in urine. White blood cells were saturated at 100 mg a day. At 500 mg, each Good C capsule is in the range where absorption starts to taper, so if you take more than one, spread them across the day. More isn't automatically better.\u003c\/p\u003e\n\u003ch3\u003eCitrus bioflavonoids, hesperidin and rutin\u003c\/h3\u003e\n\u003cp\u003eBioflavonoids are plant compounds that come packaged with vitamin C in citrus fruit.

A 2012 meta-analysis of head-to-head randomized trials found D3 raised blood 25-hydroxyvitamin D more than D2 overall. The gap was clearest with large, infrequent doses and wasn't significant in the daily-dosing trials, so D3 works at least as well as D2, and better overall in the pooled trials (\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/22552031\/\"\u003eTripkovic 2012\u003c\/a\u003e).\u003c\/p\u003e\n\u003cp\u003eVitamin D also reaches past bone: B cells, T cells and antigen-presenting cells all carry vitamin D receptors, and these immune cells can make active vitamin D themselves, which is part of how vitamin D supports normal immune function (\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/21527855\/\"\u003eAranow 2011\u003c\/a\u003e).†\u003c\/p\u003e\n\u003cp\u003eWhat the research doesn't show: that more vitamin D on top of adequate levels builds extra bone. A 2014 meta-analysis of 23 trials in 4,082 adults (average age 59) found a small bone density benefit at one hip site, about 0.8%, and none elsewhere. The authors concluded that routine vitamin D for bone density isn't supported in adults without risk factors for low vitamin D (\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/24119980\/\"\u003eReid 2014\u003c\/a\u003e).\u003c\/p\u003e\n\u003ch3\u003eVitamin K2 (all-trans MK-7), 120 mcg\u003c\/h3\u003e\n\u003cp\u003eVitamin K is a switch.

In a study in healthy volunteers, vitamin K1 and MK-7 were both absorbed well, but MK-7 stayed in the blood far longer, gave steadier levels, built up to 7- to 8-fold higher levels with prolonged daily use, and activated more osteocalcin (\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/17158229\/\"\u003eSchurgers 2007\u003c\/a\u003e).

For a 154-pound (70 kg) adult, that works out to roughly 2.5 to 2.6 grams of lysine a day, so one capsule's 400 mg covers about 15 to 16% of it. Both studies were tiny, as these studies usually are, but their numbers line up.\u003c\/p\u003e\n\u003cp\u003eHere's the candid part: if you eat enough protein, food likely covers most or all of that.

Among them are the glutathione peroxidases, which help break down hydrogen peroxide and protect the fats in cell membranes from oxidation. Others turn thyroid hormone into its active form, and selenoprotein P is one of the two main selenoproteins in your blood. \u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/22381456\/\"\u003eA 2012 review of selenium and human health in The Lancet\u003c\/a\u003e describes selenoproteins as having effects that range from antioxidant activity to the production of active thyroid hormone.†\u003c\/p\u003e\n\u003ch3\u003eWhy L-selenomethionine\u003c\/h3\u003e\n\u003cp\u003eSupplements use selenomethionine, selenium yeast, sodium selenite or sodium selenate. Your body absorbs up to about 90% of the selenium from all of them, so the difference is what happens next.\u003c\/p\u003e\n\u003cp\u003eSelenomethionine is the main form of selenium in food, and the \"L\" means it matches what food contains. Your body can use it right away or tuck it into its own proteins in place of the amino acid methionine, then release it as those proteins turn over (\u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/10867031\/\"\u003ea review of selenomethionine's metabolism\u003c\/a\u003e). That gives you a reserve instead of a quick pass-through.\u003c\/p\u003e\n\u003cp\u003eIn \u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/8490010\/\"\u003ea 32-week trial in 33 young New Zealand women\u003c\/a\u003e with marginal selenium status, participants took 200 mcg of selenium a day as selenium yeast (selenomethionine), as selenate, or a placebo. Selenomethionine raised blood selenium more than selenate did, while both forms raised glutathione peroxidase activity in the blood about equally. Translation: both forms feed the enzymes, and selenomethionine also builds the stockpile.\u003c\/p\u003e\n\u003ch3\u003eImmune support\u003c\/h3\u003e\n\u003cp\u003eYour immune system needs selenium to work normally.† The Lancet review notes that low selenium status has been linked with poorer immune function. In \u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/11575678\/\"\u003ea 120-day study in 11 healthy men\u003c\/a\u003e, participants ate diets naturally high (297 mcg a day) or low (13 mcg a day) in selenium. In lab tests, lymphocytes (immune white blood cells) from the high-selenium group multiplied more by day 45 and stayed that way, while the low-selenium group's didn't rise until day 100. Blood antibody and complement levels didn't change. It's a clue about how selenium works, not a promise.\u003c\/p\u003e\n\u003ch3\u003eThyroid hormone metabolism\u003c\/h3\u003e\n\u003cp\u003eYour thyroid holds more selenium for its size than any other organ. It mostly makes T4, the less active form of thyroid hormone, and selenium-containing enzymes convert it into T3, the active form your cells respond to. Selenium enzymes also help shield the thyroid from the hydrogen peroxide it produces while making hormone.†\u003c\/p\u003e\n\u003cp\u003eCandidly, more selenium doesn't mean more thyroid hormone. In \u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/18565425\/\"\u003ea 48-week trial in 42 healthy men\u003c\/a\u003e who already got enough selenium, 300 mcg a day as selenium yeast left thyroid hormone levels unchanged compared with placebo. Selenium supports normal thyroid hormone metabolism.† It isn't a thyroid stimulant.\u003c\/p\u003e\n\u003ch3\u003eWhat the research does and doesn't show\u003c\/h3\u003e\n\u003cp\u003eMore isn't automatically better. In \u003ca href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/20181815\/\"\u003ea 12-week trial in 119 healthy UK adults aged 50 to 64\u003c\/a\u003e, whose usual diet supplied about 55 mcg a day, selenium yeast at 50, 100 or 200 mcg raised blood selenium in step with the dose (from about 96 to 177 ng\/mL at 200 mcg). Selenoprotein P, a marker of whether the body's needs are covered, topped out with about 50 mcg extra a day.\u003c\/p\u003e\n\u003cp\u003eThe 2012 Lancet review calls the link between selenium status and health U-shaped: extra selenium may help people whose status is low, while people whose status is already adequate to high could be affected adversely and shouldn't add more. This tablet is for filling a gap, not for stacking on a selenium-rich diet. If you eat Brazil nuts most days, you probably don't need it.\u003c\/p\u003e\n\u003ch2\u003eHow to take Selenium 200 mcg\u003c\/h2\u003e\n\u003cp\u003eThe label's directions: \"One tablet daily, as a dietary supplement.\"\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOne tablet is the whole serving; don't take more unless your practitioner says so.\u003c\/li\u003e\n\u003cli\u003eAdd up your selenium.

The people who formulate, make and test this selenium work under one roof, and the owners, who have run the company since 2017, work in the same building.

The Daily Value for selenium is 55 mcg, the same as the adult RDA. The label's serving is one tablet a day, so a 60-tablet bottle lasts 60 days.\u003c\/p\u003e\n\u003ch3\u003eIs 200 mcg of selenium too much?\u003c\/h3\u003e\n\u003cp\u003eIt's half the U.S. upper limit for adults of 400 mcg a day, but that limit counts every source. The average U.S. man gets about 132 mcg a day from food and the average woman about 94 mcg, so one tablet plus a typical diet lands at roughly 295 to 330 mcg. In 2023, the European Food Safety Authority set a more cautious adult upper limit of 255 mcg a day, one more reason to add things up.\u003c\/p\u003e\n\u003ch3\u003eShould I take selenium with food?\u003c\/h3\u003e\n\u003cp\u003eThe label doesn't say either way. Its direction is simply one tablet daily, so take it at the time you're least likely to forget.\u003c\/p\u003e\n\u003ch3\u003eHow long does it take to notice selenium?\u003c\/h3\u003e\n\u003cp\u003eYou probably won't feel it, since selenium works quietly inside enzymes. What changes is your selenium status: in the 12-week UK trial, blood selenium climbed for weeks and leveled off by about week 10. It's a daily habit, not a quick fix.\u003c\/p\u003e\n\u003ch3\u003eCan I take it with one of your multivitamins?\u003c\/h3\u003e\n\u003cp\u003eYes, but count the selenium. Our \u003ca href=\"https:\/\/www.mtangelvitamins.com\/products\/mens-multi-vitamin-60-capsules\"\u003eMen's Multi\u003c\/a\u003e has 70 mcg per 2-capsule serving and our \u003ca href=\"https:\/\/www.mtangelvitamins.com\/products\/womens-multi-cap-60ct\"\u003eWomen's Multi\u003c\/a\u003e has 50 mcg, both as L-selenomethionine. Add this tablet and you're at 250 to 270 mcg from supplements before any food, so ask your practitioner whether you need both.\u003c\/p\u003e\n\u003ch3\u003eWhy L-selenomethionine instead of sodium selenite or selenate?\u003c\/h3\u003e\n\u003cp\u003eBecause it's the main form of selenium in food and your body can hold it in reserve in its proteins. Your body absorbs all of these forms well, but in the 32-week trial above, selenomethionine raised blood selenium more than selenate at the same 200 mcg dose.\u003c\/p\u003e\n\u003ch3\u003eIs selenium safe with medication or during pregnancy?\u003c\/h3\u003e\n\u003cp\u003eAsk your healthcare practitioner first. Some medications can affect selenium levels, and pregnancy and nursing change how much you need (the RDA is 60 mcg during pregnancy and 70 mcg while nursing).
