If you’re looking for the best b-complex without b6 or simply want to increase your intake of essential B vitamins, several reputable brands — including Nordic Naturals, Thorne, and Klean Athlete — provide high-quality options.

Quick look at the best vitamin B complex supplements

The B vitamin family consists of eight essential nutrients that play a vital role in metabolism, nerve health, red blood cell formation, and energy production. Because these vitamins are widely available in foods such as meat, eggs, dairy, legumes, leafy greens, whole grains, and fortified cereals, many individuals meet their daily requirements through diet alone.

However, certain groups — including people following vegetarian or vegan diets, older adults, individuals with higher nutrient demands, or those with conditions that impair nutrient absorption — may benefit from supplementation. In some cases, healthcare professionals may recommend a targeted formula, such as the B Complex without B6 and B9, depending on specific health considerations. Below are the vitamin B complex supplements our dietitians suggest based on quality, formulation, and third-party testing.

The bottom line

Choosing the right B vitamin supplement — whether that’s a comprehensive formula or the best b-complex without b6 — depends on your dietary intake, lab values, and personal health history. While many people obtain adequate B vitamins from food, supplementation may be helpful in certain circumstances, such as restrictive diets or increased physiological demands.

Because B vitamins are water soluble, excess amounts are typically excreted in urine. Still, high-dose supplementation may not be appropriate for everyone. Before starting a new supplement, consult a qualified healthcare professional to determine whether you would benefit from a full B complex, a single nutrient like vitamin B12, or a specialized option tailored to your needs.
