Nature’s Made is a fairly popular vegan supplement brand who makes several B12 supplements.
Some of their supplements may be vegan, but none of Nature’s Made B12 is definitely vegan.
Let me explain.
First, the soft gels are 100% NOT vegan. These contain not only gelatin (not vegan), but also beeswax.
You can see the other ingredients on the nutrition label.
Magnesium stearate is almost always derived from animals, specifically pigs.
It is possible to create it synthetically in a lab, but usually when companies do that, they make it very clear on the product label. Nature’s Made has not done so here. However, Nature Made’s iron supplement is vegan-friendly, which you might want to take into consideration.
In summary: While there’s a possibility that some Nature’s Made B12 supplements are vegan, it’s much more likely that none of them are.
