The vitamin is found in the germ and aleurone layer of grains, so there is more in whole wheat bread compared to white bread wheat, and more in brown rice compared to white rice.Most values shown in the table are rounded to nearest tenth of a milligram:

Fortification
As of 2019, fourteen countries require food fortification of wheat flour, maize flour or rice with vitamin B6 as pyridoxine hydrochloride. Most of these are in southeast Africa or Central America. The amounts stipulated range from 3.0 to 6.5 mg/kg. An additional seven countries, including India, have a voluntary fortification program. India stipulates 2.0 mg/kg. Dietary supplements
In the US, multi-vitamin/mineral products typically contain 2 to 4 mg of vitamin B6 per daily serving as pyridoxine hydrochloride, but a few contain more than 25 mg. Many US dietary supplement companies also market a B6-only dietary supplement with 100 mg per daily serving. While the US National Academy of Medicine sets an adult safety UL at 100 mg/day, the European Food Safety Authority sets its UL at 25 mg/day. Health claims
The Japanese Ministry of Health, Labour, and Welfare (MHLW) set up the Foods for Specified Health Uses (特定保健用食品; FOSHU) regulatory system in 1991 to individually approve the statements made on food labels concerning the effects of foods on the human body. The regulatory range of FOSHU was later broadened to allow for the certification of capsules and tablets.
Second-line treatment is the same as for nonseminomas.Stage 3 seminoma is characterized by the presence of metastasis outside the retroperitoneum—the lungs in "good risk" cases or elsewhere in "intermediate risk" cases. This is treated with combination chemotherapy. Second-line treatment follows nonseminoma protocols. References
