Our vitamin supplements

Yes – as long as you stay within the recommended guidelines. Vitamin supplements are subject to strict regulations that define how much of each vitamin may be included. The number one rule? A supplement must be safe. If you're thinking about exceeding the suggested intake, it’s always best to check in with a healthcare professional first. Because even with vitamins, one thing always holds true: it’s the dose that makes the difference.

Hardly – and definitely not enough to impact your daily intake. Unlike fats, carbs, or protein, vitamins themselves don’t provide energy. Most supplements contain little to no calories. Some capsules or tablets may include tiny amounts of carrier or filler substances, but these are so minimal they don’t make a difference in your calorie balance.

So if you're keeping an eye on your calorie intake, no worries – your vitamins have your back without tipping the scales. Just pure support for your body, no extra energy on the side.

The answer depends on your life situation. In general, a well-rounded diet provides most of the essential nutrients your body needs. But there are times when your nutrient needs go beyond what food alone can cover – like during pregnancy, intense physical activity, growth phases, or when following a plant-based diet.

Take folic acid and iron, for example: pregnant people often need significantly more of both – and it’s nearly impossible to get those amounts through food alone. The same goes for vitamin B12 in vegetarian or vegan diets, or calcium if you're lactose intolerant. In these moments, targeted supplements can be a smart way to give your body exactly what it needs – nothing more, nothing less.

Surprisingly well – because for the most part, your body doesn’t know the difference. Synthetic vitamins are usually identical in structure to the ones found in nature (with a few exceptions, like folic acid). That means your body processes them the same way – whether they come from a carrot or a capsule. In short: same vitamin, same effect.

Good news: our products are moving to Green PE packaging – and you can be part of the change. The BIOGENA eco-tube is made from renewable sugarcane, a plant that naturally binds CO₂ and helps reduce our environmental footprint. When you're done with your supplement, simply dispose of the Green PE bottle in plastic recycling. It’s a small step with a big impact – for your health and the planet.
