No good human study has tested folic acid on its own for constipation. A national survey of about 13,900 United States adults found that people eating the most folate had lower odds of constipation, but a survey cannot show that folate caused this [1]. Hong Kong preschool children with constipation ate less folate, and also less fiber and fewer plant foods [2]. A small 10-day pilot in 40 women found that a kombucha drink with folic acid, the fiber inulin and other vitamins improved bowel movements, so the benefit cannot be credited to folate [3]. In pregnancy and after childbirth, iron and folate tablets often caused constipation, likely from the iron [4][5][6]. This product has 70 milligrams of calcium, far below the studied doses. Large trials using 1 to 1.2 grams of calcium a day found more constipation than placebo [7][8]. A trial in men found no difference from placebo [9]. Small trials using 500 milligrams a day found no change in stool frequency [10][11]. Benefit appeared only with calcium polycarbophil, a bulk-forming fiber, which is not the plain calcium in this product [12]. Animal and cell studies are never counted.

Biohacker Summary

Members Only0 of 10 recommend it
0 of 10 biohackers on our panel recommend it

The product is folic acid, and the panel spoke about folate (the natural form) more than the supplement itself, with most of them backing it or treating it as useful. Four of the ten recommend folate, mostly for lowering homocysteine, and also for mitochondrial function, hearing health in older people, and IVF preparation, while one more likes it as a way to correct a low level and one credits folate supplementation with sharply reducing spina bifida. The clear preference is methylfolate, the active form the body can use directly, and two of them say it is better than synthetic folic acid; one suggests getting it through a prenatal vitamin, and dark leafy greens are named as a food source. Cautions are limited: two note that birth control pills or a med can deplete folate, and no one said they stopped taking it. Calcium, listed as a smaller ingredient in this product, drew mixed views, with several backing it for bones and others warning about calcium carbonate and supplements.

RAL Summary

Members OnlyTier 4 for Regularity: Long-Term Relief

The folate evidence for constipation comes from surveys and a mixed-ingredient drink, not trials of folate alone, and there are no reviews, so the evidence is thin [1][3]. The small calcium dose is well below doses that were studied, which did not help [8].

  • Emerging: not enough evidence to rank higher yet.

Where the evidence disagrees: 14 of the 26 human studies found no effect.

More Details

Members OnlyBody systems · Combine with · Possible side effects

Body systems: Digestive system

Possible side effects: No major side effects reported for folic acid alone in these studies. Constipation was seen with iron and folate tablets, likely from the iron, and with high-dose calcium far above this product's 70 milligrams.
