Supplements Studio Vegan Daily Multivitamin for Women with Iron, Biotin, Probiotics, Enzymes & Superfoods Review

For energy, the best support in this multivitamin comes from vitamin D, given here at a full studied dose. It eased tiredness mainly in people low in vitamin D: one trial saw 72% improve versus 50% on placebo ^[1], and 2,000 units daily lowered fatigue in active men ^[2]. A very large trial using a lower dose found no change in energy ^[3]. Iron reduces tiredness in people low in iron ^[4][5], but not in people with normal iron ^[6]. Magnesium results are mixed. Oral magnesium helped some groups with health conditions ^[7][8], while other trials found no benefit ^[9]. Selenium, at half the studied dose per capsule, showed modest gains in some groups ^[10] but none in a large trial of healthy adults ^[11]. Vitamin A, vitamin E, thiamine and vitamin B6 are well below the doses studied. Vitamin B12, folate, niacin and zinc showed little or no energy benefit in controlled trials ^[12][13][14]. The probiotics and enzymes are hidden in blends, with only small trials showing weak or no effect ^[15][16]. Animal and cell studies are never counted.

Magnesium is the main ingredient, and the panel leans favorable: four of the ten take it themselves, one recommends it for sleep, and the rest mention it neutrally or with a caution. Sleep is the most common reason, with others citing stress resilience, muscle recovery, workout performance, and calming hunger around a fast. Preferred forms are glycinate and threonate, with one panelist taking 400 mg of threonate before bed and another using a 30 milligram electrolyte drink in the morning. One panelist notes that magnesium alone does not fix waking up during the night, and another warns that labels can make the dose look larger than it really is. Vitamin D, vitamin C and zinc are smaller ingredients in this product that several panelists also recommend, while one panelist said that no form of iron ever raised his levels.

The tier rests on an 80% improvement figure that comes from one small trial of weekly magnesium sulphate injections in chronic fatigue syndrome, not oral magnesium like this capsule, and the magnesium studies overall are mixed (7 improved, 9 no effect). So it is graded Tier 3, lower than the rules alone gave.

Combine with: For mood support, pair this multivitamin with a high-EPA omega-3 fish or algal oil (1-2 g EPA+DHA daily), which has the best evidence for supporting emotional balance. Add vitamin D3 with K2 if levels are low, and magnesium glycinate for nervous system and mood regulation. Saffron extract (about 30 mg daily) or L-theanine can offer targeted mood and calm benefits, and methylfolate with methylcobalamin supports neurotransmitter synthesis if the multivitamin's amounts are modest. Ashwagandha or rhodiola may help if stress is driving mood changes. Women who are not iron deficient should check ferritin levels before long-term supplemental iron, and should separate iron from calcium, zinc or coffee to improve absorption.
