With nearly two decades of experience, the brand offers many products, including vitamins, minerals, plant-based supplements, devices, and more. Now reaching multiple countries, the focus remains on developing products that evolve with changing needs while staying true to the values that started it all.
NON-GMO & GLUTEN-FREE: WeightWorld's Vitamin B12 Supplements are made in the UK under GMP guidelines and are vegan-friendly. These carefully formulated vitamin B12 tablets are gluten-free, non-GMO, and formulated to support various dietary needs.
MULTIPLE USES OF VIT B12 SUPPLEMENTS: Vitamin B12 contributes to normal energy-yielding metabolism. Vitamin B12 contributes to normal functioning of the nervous system. Vitamin B12 contributes to normal homocysteine metabolism. Vitamin B12 contributes to the reduction of tiredness and fatigue (EFSA Claims).
LONG-LASTING SUPPLY: WeightWorld's Vitamin B12 1000mcg Tablets contain Methylcobalamin, an active form of Vitamin B12. Easy to swallow, each 6mm micro tablet delivers 1000mcg of Methylcobalamin (40,000% NRV). Each bottle contains 450 tablets, providing a supply that lasts well over a year.
KEY VITAMIN FOR VEGANS: Since vitamin B12 cannot be stored in the internal system, it must be obtained through diet. Naturally present in shellfish, meat, and dairy, maintaining adequate B12 levels can be challenging for vegans and vegetarians. WeightWorld's Vitamin B12 Supplement is vegan-friendly and thoughtfully formulated to suit any lifestyle.
