vitamin B
Verified Purchase
Excellent, the package contains 100 tablets, just enough for a course for three people. I took them in the morning and had no discomfort. Within a month, my husband and I definitely lost less hair. The tablets are a convenient size and easy to swallow. The packaging contains mica. I've become more energetic and sleep well. Affordable and high-quality.

I'll write the result later. The quality is good, by the way, I noticed that when I don't take B vitamins, I'm drawn to liver and nuts, when I do, I don't notice such preferences.

Serving Size: 1 Softgel Amount Per Serving • Thiamine (as thiamine hydrochloride) — 1.5 mg • Riboflavin — 2 mg • Niacin (as niacinamide) — 10 mg • Vitamin B6 (as pyridoxine hydrochloride) — 0.1 mg • Pantothenic acid (as d-calcium pantothenate) — 1 mg • Brewer's Yeast — 100 mg • Liver (defatted Liver) — 70 mg What's good about it: • Natural sources of B vitamins — brewer's yeast (100 mg) and defatted liver (70 mg). These are not just synthetic supplements, but natural products that contain the B-vitamin complex in its natural form, plus additional beneficial substances (e.g. trace elements, amino acids, folic acid, etc.). • Brewer's yeast and liver are traditionally considered “superfoods” for B vitamins — they provide high natural concentrations of B12, folic acid (B9), and other B vitamins that are often lacking in the diet. • Helps with energy, metabolism (converting food into energy), nervous system, heart, and immune support. • Very low doses of synthetic B vitamins (e.g., B6 only 0.1 mg) — this means that the complex does not “overload” the body with high doses, but relies more on natural sources. Good for those who want gentle support without the risk of overdosing. • Softgels form — convenient, easy to swallow, no liver or yeast smell/taste. • Budget-friendly, large volume (100 capsules), often praised for its price/quality ratio on iHerb. Is there B12? Yes, there is vitamin B12, but it is not listed separately in synthetic form on the label (which is why it is not listed in mg). It comes naturally from brewer's yeast and liver - these components are rich in B12 (liver in particular is one of the best natural sources of B12). Many product descriptions directly write: “Brewer's yeast and liver provide high potencies of B12 and folic acid”. That is, B12 is present there in its natural form (probably a few mcg per capsule, depending on the quality of the raw material), but it is not synthetic cyanocobalamin or methylcobalamin with a high dose (like in many other B-complexes at 50–1000 mcg).

Mason Natural, B-Complex. Working B-complex
Verified Purchase
I took it to support energy and the nervous system. The composition is basic, but the dosages are adequate and not excessive. After a week of taking it, daytime drowsiness disappeared, and energy appeared. The capsules are soft, easy to swallow, although a little large. They smell of B vitamins, which is normal.
