One vegetarian capsule a day from Jarrow Formulas with all eight B vitamins plus choline, pantethine and inositol; 100 capsules a bottle. Folate is (6S)-5-MTHF, B12 is methylcobalamin, and B6 is split between pyridoxine and P-5-P.
All eight B vitamins run from 156% to 4,167% of the Daily Value. Niacin is in the nicotinic-acid form that can flush, and B6 totals 35 mg, a third of the US upper limit. Choline, at 9% of the DV, is a token amount.
Adults past forty who eat little animal food, take a common blood-sugar or acid-reducing medicine that can lower B12 status, or simply want one capsule of B vitamins in active forms, taken with breakfast.
Do not stack it on a multivitamin that already carries high B's: B6 and niacin totals climb past the limits fast. Expect bright-yellow urine and a possible warm flush. Tell any lab that you take biotin. Antiepileptic and methotrexate users should ask first.
What the label shows
We read the Supplement Facts panel on Jarrow Formulas' own product page and the ingredient text on the Amazon listing for the 100-capsule bottle (ASIN B0016003Z0) on September 30, 2026 [1]. They match. Amounts below are per capsule; the Daily Values are the FDA's current adult values [2], and every recommended intake and upper limit comes from the NIH Office of Dietary Supplements fact sheet for that vitamin.
| Ingredient | Amount per serving | What to know |
|---|---|---|
| Thiamin (B1, as thiamine mononitrate) | 25 mg — 2,083% DV | RDA 1.2 mg (men) / 1.1 mg (women). No upper limit set. The NIH notes that up to 20% to 30% of older adults have laboratory signs of some degree of low thiamin [3]. |
| Riboflavin (B2) | 25 mg — 1,923% DV | RDA 1.3 mg / 1.1 mg. No upper limit set. Riboflavin is yellow and the absorbed surplus leaves in urine, which is why urine turns bright yellow [4]. |
| Niacin (B3, as nicotinic acid) | 25 mg NE — 156% DV | RDA 16 mg NE / 14 mg NE. Upper limit 35 mg for niacin from supplements. Nicotinic acid, unlike niacinamide, can cause a temporary skin flush, more so on an empty stomach [5]. |
| Vitamin B6 (25 mg pyridoxine HCl + 10 mg pyridoxal 5-phosphate) | 35 mg — 2,059% DV | RDA 1.7 mg (men 51+) / 1.5 mg (women 51+). US upper limit 100 mg; a European panel set 12 mg in 2023. The one number on this label to respect [6]. |
| Folate (400 mcg as (6S)-5-MTHF glucosamine salt) | 680 mcg DFE — 170% DV | RDA 400 mcg DFE. The 1,000 mcg upper limit applies to folic acid; the NIH says a DFE conversion for 5-MTHF has not been formally set, so the 680 figure borrows the folic-acid factor [7]. |
| Vitamin B12 (methylcobalamin) | 100 mcg — 4,167% DV | RDA 2.4 mcg; no upper limit set. The stomach's binding protein carries only 1–2 mcg per dose; the rest is absorbed at a much lower rate [8]. |
| Biotin (as d-biotin) | 300 mcg — 1,000% DV | Adequate intake 30 mcg; no upper limit set. Biotin above recommended intakes can distort certain blood tests [9] [10]. |
| Pantothenic acid (B5, as calcium D-pantothenate) | 100 mg — 2,000% DV | Adequate intake 5 mg; no upper limit set because no toxicity has been reported [11]. |
| Choline (as choline bitartrate) | 50 mg — 9% DV | Adequate intake 550 mg (men) / 425 mg (women). Eggs and meat, not this capsule, are where choline comes from [12]. |
| Pantethine | 25 mg — DV not established | A B5 derivative studied at around 900 mg a day for blood lipids; 25 mg is a token amount [11]. |
| Inositol | 50 mg — DV not established | No reference intake exists. |
Other ingredients: the capsule (hydroxypropylmethylcellulose and water), microcrystalline cellulose, silicon dioxide, calcium phosphate, and magnesium stearate and stearic acid of vegetable source. The label states the product contains no wheat, gluten, soybeans, dairy, egg, fish or shellfish, peanuts or tree nuts, or sesame. The "vegan" and "gluten free" icons on the bottle and the "Non-GMO" wording on Jarrow's site are the maker's own statements; no USP, NSF or other third-party certification mark is printed on the label. Directions are one capsule once a day with a meal. The label warning is unusually specific and worth quoting in substance: biotin may interfere with lab and blood tests; nicotinic acid may cause a flush, especially on an empty stomach, with burning, tingling, itching or redness and possibly dizziness or shortness of breath; and anyone pregnant, nursing, under 18, on medication (especially antiepileptic or chemotherapy drugs) or managing a medical condition should consult a professional first [1].
What the evidence shows
What "energy" means here. Jarrow's label says the formula "supports cellular energy" [1]. In the NIH fact sheets, the B vitamins are coenzymes: thiamin, riboflavin, niacin, B6, pantothenic acid and biotin each sit inside the reactions that release energy from carbohydrate, fat and protein [3] [4] [5]. That is biochemistry, not a feeling. Those reactions need adequacy, and the fact sheets describe benefits of supplementation in people who were short of a vitamin; none of them describes a lift in energy from taking twenty times the RDA when you were not. If you are tired, the honest questions are sleep, iron status, thyroid and medicines, which a clinician can check.
Vitamin B12 and the years past fifty. The strongest case in the capsule is B12. The NIH lists older adults among the groups more likely to run low on B12, and explains that B12 in food is bound to protein and must be freed in the stomach, while the B12 in supplements is already in free form and skips that step [8]. Metformin and acid-reducing medicines (proton-pump inhibitors and H2 blockers) can lower B12 levels over time, which is a reason to ask about supplementing, not a reason to self-prescribe [8]. Methylcobalamin is one of the two active forms; the NIH notes that cyanocobalamin is converted to those forms in the body and that no evidence shows absorption rates differ by form [8]. At 100 mcg, only a small fraction of the dose is absorbed, which is normal and is why B12 doses on labels look so large.
Folate as 5-MTHF. The NIH explains that 5-MTHF is the main form of folate in blood, that supplements containing it are available, and that people with a common variant of the MTHFR gene convert folic acid less efficiently and might benefit more from the 5-MTHF form; it also notes that the CDC still recommends folic acid, not 5-MTHF, for anyone who could become pregnant [7]. The NIH also describes a long-standing concern that large amounts of folate could hide or worsen the effects of a B12 shortfall [7]; this capsule carries B12 alongside, which is not a substitute for having B12 status checked if you are concerned.
Vitamin B6: the number to respect. The NIH describes severe, progressive nerve damage with loss of coordination in people who took 1–6 grams of pyridoxine a day for one to three years, notes reports of nerve symptoms at lower doses, and explains that the US upper limit of 100 mg was set by halving the 200 mg a day that studies of patients treated for up to five years had found no nerve problems with [6]. In 2023 the European food-safety panel went further and set 12 mg a day after its own review of nerve-symptom reports [6]. This capsule's 35 mg is a third of the US limit and nearly three times the European one. On its own, for an adult, that is inside the US guidance; stacked on a 50+ multivitamin with 20 mg (Report R-01), it is 55 mg a day for as long as you keep both bottles. The reports of harm involved much larger amounts, but they also involved exactly that kind of open-ended daily use, and the European limit reflects concern at far lower intakes.
Niacin as nicotinic acid. The NIH notes that supplemental nicotinic acid beyond nutritional need can cause skin flushing, and that niacinamide does not [5]. Jarrow chose nicotinic acid and says so on the warning. Twenty-five milligrams is under the 35 mg supplemental limit alone; a multivitamin's 35 mg of niacinamide on top makes 60 mg.
Biotin and blood tests. The FDA has issued guidance to test manufacturers because biotin in a patient's blood can distort assays that use biotin-streptavidin technology [10], and the NIH says intakes above recommended amounts can produce falsely high or falsely low results depending on the test, including some thyroid and vitamin D measurements [9]. Most reports involve far larger doses than 300 mcg, but the label's instruction to tell your clinician and lab is the right one, and you can ask whether to pause it before a draw.
Thiamin, riboflavin and pantothenic acid. These are the safe surpluses. The NIH lists no upper limits for any of the three and notes that riboflavin's limited absorption is why very high intakes show no observable toxicity [3] [4] [11]. Pantethine, the B5 derivative Jarrow highlights, was studied at a median of 900 mg a day for blood lipids in small trials; 25 mg is nowhere near that [11].
Count your B6 across every bottle. This capsule (35 mg) plus a typical 50+ multivitamin (20 mg) is 55 mg a day, still under the US limit of 100 mg but far above the 12 mg European limit, and the nerve symptoms reported at high doses came from months and years of daily use. Pick one B source, not two, and keep the total where your clinician is comfortable.
Who it may suit, and who should look elsewhere
It may suit adults past forty who eat little meat, fish, eggs or dairy; who take metformin or an acid reducer and have been told to watch their B12; or who prefer one capsule of B vitamins in the active forms and take no other multivitamin. Take it with breakfast: the flush is milder with food, and the yellow urine is harmless. Consider looking elsewhere, or asking first, if any of these apply:
- You already take a multivitamin with high B vitamins: the totals for B6 and niacin, not this label, decide whether you are over a limit.
- You take antiepileptic medicines or methotrexate: the label and the NIH both flag interactions with B6 and folate; ask the prescriber [6] [7].
- You have blood work scheduled: tell the lab about the biotin, or ask whether to pause the capsule beforehand [9].
- You would rather not flush: a niacinamide-based complex avoids it.
- You are pregnant, nursing or under 18, or take any prescription medicine: the label says consult a professional first.
Price, size and where it is sold
On September 30, 2026 the 100-capsule bottle (ASIN B0016003Z0) was $19.99 on Amazon.com, or $0.20 per capsule and per day, listed as in stock and shipped and sold by Amazon.com. One bottle is a little over three months at one capsule daily. The listing was marked non-returnable for food-safety reasons, so Amazon's general 30-day return window does not apply; our returns page explains what that means in practice. A second, older Amazon listing for B-Right (ASIN B0001VKCQA) still shows a previous formula with folic acid, PABA and a gelatin capsule and an expiry note from 2019; it is not the product described here, and we do not link it. Jarrow's own site is cited as a label source only, not as a place to buy [1]. Prices change; the figures above are observations on the date given.
