Sisu Vitamin B12 5000 mcg


Low energy is one of the most prevalent health complaints. If you have tried various ways to boost your energy and still feel lethargic, you may be suffering from vitamin B 12 deficiency. Vitamin B12 is a key factor in the formation of red blood cells and the production of energy in the cells; yet this nutrient is often overlooked. In the short term, insufficient vitamin B12 levels can result in deep fatigue, weakness, problems concentrating, shortness of breath, and mood changes, which prevent you from feeling and performing at your best. In the long term, vitamin B12 deficiency can lead to more severe nerve-damage symptoms, including numbness or tingling of hands and feet, poor sense of balance, depression, dementia, and loss of mental abilities.
Vitamin B12 supplementation is recommended at any age, but can be beneficial for people who have a vegetarian or a vegan diet and older people who suffer from age-related degenerative conditions. Supplements are a convenient way to ensure adequate vitamin B12 levels and high-potency formulas are an ideal alternative for people currently receiving injections.


    • Vitamin B12 in its active form methylcobalamin for accelerated absorption
    • High-potency tablets, ideal for those who require high doses and want to avoid vitamin B12 shots
    • Vitamin B 12 is essential for the formation of red blood cells, for the production of energy in the cells, and is a key factor in the making of DNA
    • In combination with vitamins B6 and folic acid, vitamin B12 helps normalize homocysteine levels to support cardiovascular health
    • Vitamin B12 levels can be negatively affected by a variety of substances, including alcohol, oral contraceptives, and certain medication

Directions: Take 1 tablet 1 time per day or as directed by a health care practitioner.

Great product

Karen Lorentz
Vitamin B12

I didn’t receive my vitamin B12, a mistake was made and I got vitamin D which I didn’t want, but I really like the vitamin B12 my husband has a vitamin B12 deficiency which helps keep his energy levels consistent

Romina Costantini
Very good.

I have seen a great improvement in my energy since using this product. I had been taking a regular slow release B12 for almost a year with no results. After 3 weeks of the Sisu B12, I can feel a significant difference.

Nancy Porter-Steele

Very satisfactory.


Like that it melts in the mouth and has a pleasant taste. I feel it is helping with my B12 levels.
