No study has tested this B-complex, or any single B vitamin in it, for fast relief of occasional heartburn. The strongest human evidence is indirect. A large diet survey linked more riboflavin, vitamin B6 and folic acid from food to lower odds of one type of reflux, but this shows only an association [1]. A smaller study linked more riboflavin and folate from food to less inflammation of the food pipe [2]. A trial in people with reflux found a blend of melatonin, vitamin B6, folic acid, vitamin B12 and other nutrients worked better than an acid-reducing drug over about 40 days, but this product has no melatonin and the vitamins' own share is unknown [3]. Other studies disagree: one linked more vitamin B6 to more reflux [4], and folic acid did worse than an herbal remedy for upper-stomach pain [5]. Thiamine helped indigestion only when injected into acupuncture points [6]. Vitamin B12 here is 100 micrograms, below the 1000 micrograms studied for indigestion [7]. Choline evidence is from animals only [8]. Animal and cell studies are never counted.

Biohacker Summary
Members Only0 of 10 recommend it
0 of 10 biohackers on our panel recommend it
Folate is the main ingredient, and the panel leans positive: five of the ten recommend it and the other five are neutral, with no one warning against it or stopping it. The two who named a form both prefer methylfolate, described as an active form the body can use directly, and one links it to mitochondrial function. People mainly take it to lower homocysteine, to cover low intake from food, and to support brain health during pregnancy, with one noting it helped reduce spina bifida and another using it to correct a child's low folate levels. No one gave a folate dose, and the only pairing mentioned was a prenatal vitamin for women preparing for IVF. Among the smaller ingredients in this product, inositol drew the most attention, with several panelists taking 900 mg before bed for sleep.

- States that Nrf2 activators, when combined with something like niacin, may have a good effect on plaque progression.
- Addresses her MTHFR gene by taking choline rather than high doses of methylolate.
- Recommends bioavailable folate, not synthetic folic acid, as folate deficiencies seem to impact hearing health in older individuals.
- Recommends getting vitamin B12 tested and supplementing if deficient, as B12 deficiency can cause damage to the myelin coating around nerves, including cochlear nerves, and improve tinnitus severity scores.
- Mentions nicotinamide as an ingredient found in many NAD products and notes that niacinamide and nicotinamide are structurally the same.
- Recommends introducing methylfolate into the diet to address high homocysteine levels.
- Believes the niacinamide approach, along with the NAMPT/salvage pathway angle, is underrated and deserves more attention.
- Takes 900 mg of Inositol before bed for sleep.
Thomas DeLauer · Folate · recommends
- Recommends taking methylfolate as a methylated form of B vitamin for mitochondrial function.
- Recommends Vitamin B12 for mental health and mood, explaining its role in myelination and neurotransmitter production. They specifically recommend a liposomal and micellar form of methylcobalamin B12 for better absorption and to avoid toxicity.
- Mentions that choline from avocado (and eggs) contributes to the liver's ability to tag and process toxins, focusing on phase II detox.
- Uses niacin as part of their detoxification protocol, taking enough to flush about half an hour before a sauna session.
- Warns against conventional cereal, describing it as extruded, sugared, and then sprayed with vitamins that were destroyed during its making.
- Warns against conventional cereal, describing it as extruded, sugared, and then sprayed with vitamins that were destroyed during its making.
- Mentions that a single serving of sardines provides vitamin B12 at something like three to four times the daily needs.
- Recommends taking methylcobalamin as a methylated form of B vitamin for mitochondrial function.
- Discusses niacin as an essential vitamin involved in NAD production and known for its flushing effect as a vasodilator. He also mentions its role as an agonist for GPR109A receptors, which could potentially block fat mobilization.
- Thinks biotin is a little overhyped, suggesting that consuming adequate protein is probably more effective for hair, skin, and nails. He notes that some people might be deficient, especially if consuming a lot of eggs with avidin, but doesn't consider it the 'Mecca of perfect hair'.
- Recommends methylfolate as a runner-up for insulin resistance, especially for individuals with the MTHFR variant, as it directly enters the methylation cycle without conversion.
- Recommends ensuring adequate vitamin B6 intake, as it is a required cofactor for cells to use absorbed magnesium and improves central nervous system relaxation when combined with magnesium.
- Explains that choline is the direct precursor to acetylcholine, a neurotransmitter tied to memory, attention, and learning speed, and that most adults don't get enough of it.
- Recommends vitamin B6 to support GABA production and find balance for mental clarity.
Siim Land · Folate · neutral

- Created Microvitamin, a supplement that bundled all the supplements he was taking, to help fund his a med trial.
- States that vitamin B12 deficiency is the most common reason for premature graying of hair and recommends fixing B12 status if it is deficient, as it gives a greater likelihood of reversing gray hair.
- Suggests that in the mornings, NAD supplements like niacinamide can help kickstart the circadian rhythm.
- Recommends Niacinamide for skin protection, explaining it works partly through NAD metabolism that the body uses against DNA damage and is found in protein sources.
- Mentions that only specific therapies like niacin can meaningfully reduce Lp(a).
- Likes inositol, stating it helps with neurotransmitters, mood, and blood sugar regulation, placing it in the 'good tier'.
- Notes that Niacin notoriously raises HDL cholesterol, but this increase does not lower the risk of heart disease events, and while it can be good in many cases, very high doses can affect liver function.
- Places Thiamine, Vitamin B1, in the 'good' tier for its benefits in blood sugar regulation and energy metabolism, noting that he personally takes bentothiamine occasionally, especially when consuming many carbohydrates.
Andrew Huberman · Folate · recommends

- Takes 900 mg of Inositol before bed for sleep.
- Mentions inositol for PCOS, stating it decreases insulin resistance and offers a huge benefit.
- Mentions biotin.
Peter Attia · Folate · recommends
- Highlights folate supplementation as a significant practical progress in nutrition science, which has radically reduced spinabifida.
- Peter Attia's AVIA Skincare vitamin C serum also contains niacinamide, which is useful to apply to the skin right after washing.
- Warns that biotin, found in many supplements, can completely obscure findings and render a non-LCMS test for estradiol and testosterone irrelevant due to interference with ELISA-based assays.
- Notes that deficiencies in certain vitamins and minerals, such as B12, can be a cause of hair loss in women.
- States that for choline deficiencies, which are sometimes measurable and seen in people post-bariatric surgery, they are not terribly aware of any downsides to taking choline supplements, but cautions about quantifying what's in supplements.
- Advises that if taking a biotin supplement, one should discontinue it for at least a few days, if not a week, before a blood test, as it can dramatically skew thyroid values.

- Personally takes methylfolate to help get homocysteine into the desired zone and prefers the Jarrow brand.
- Used to prescribe niacin to many patients, primarily to raise HDL, lower APO B, triglycerides, LDL, and LP(a), but stopped after clinical trials showed minimal or disappointing effects on reducing cardiovascular events.
- Notes that niacin lowers LP little a but was not shown to have clinical benefit in outcome studies, and they are not currently using it.
- Recalls that a flush from niacin typically occurred with doses of a few grams.

RAL Summary
Members OnlyTier 4 for Occasional Heartburn: Fast Relief
The tier rests on a diet survey linking folate from food to lower reflux odds, which is only an association and did not test folate supplements, and the one trial tested a blend with melatonin, so no study shows a clear improvement from these vitamins for heartburn. So it is graded Tier 4, lower than the rules alone gave.
- Emerging: not enough evidence to rank higher yet.
Where the evidence disagrees: 7 of the 17 human studies found no effect.
