Vitamin B6 and Vitamin B12 (250 mg each)
Why exactly 250 mg
250 mg is a high therapeutic dosage, significantly exceeding the standard daily requirement (usually 1.3–2 mg). It is used in specialized nervous system support programs, for deficiencies, and to improve mood and restore energy.
Benefits of Vitamin B6 (Pyridoxine, 250 mg)
-
Reducing anxiety and depression. Clinical studies have shown that high doses of B6 enhance the action of GABA (gamma-aminobutyric acid), reducing anxiety states and symptoms of depression (ncbi.nlm.nih.gov [1]).
-
Strengthening immunity and the nervous system. B6 is involved in more than 140 enzymatic reactions, including the synthesis of serotonin, dopamine, and immune cells.
-
Supporting energy metabolism. Aids in the conversion of proteins, fats, and carbohydrates into energy, reducing fatigue and increasing endurance.
Benefits of Vitamin B12 (Cobalamin, 250 mg)
-
Energy, blood formation, and nervous system protection. B12 is critically important for red blood cell production, cell metabolism, nerve function, and DNA synthesis (mayoclinic.org [4]).
-
Improving cognitive function. According to reviews, B12 may slow memory decline in people with elevated homocysteine levels (alzdiscovery.org [3]).
-
Supporting psycho-emotional state. Low B12 levels are associated with an increased risk of depression, and supplements improve the effectiveness of therapy for mood disorders (consensus.app [5]).
Safety and Dosage
-
Vitamin B6: The standard recommended dose is about 1.3 mg, the maximum tolerable upper intake level (UL) is 100 mg per day. Taking 250 mg may lead to sensory neuropathy with long-term use (healthline.com [6], sciencedirect.com [7], wikipedia.org [2]).
-
Vitamin B12: No upper limit for dosage has been established. Doses up to 250 mg (250,000 mcg) are considered safe, especially for vegetarians, the elderly, or those with severe deficiency.
Who Should Pay Attention
-
People with chronic stress, anxiety, or depressive conditions

Efficacy confirmed by clinical studies and review data
Conclusion
A complex of vitamins B6 and B12 at a dosage of 250 mg each is a powerful tool for supporting psycho-emotional state, cognitive functions, and physical activity. It is especially relevant for people with high stress levels, in conditions of deficiency, and with age-related changes. With reasonable use and under a doctor's supervision, it can become part of a daily health care strategy.
