This GEN product combines vitamin D3 with vitamin K2 MK-7 in one tablet. The D3 is sourced from lichen, not lanolin as in most D3 supplements. This makes it a completely plant-based variant. Per tablet, you get 5,000 IU of vitamin D3 and 200 µg of K2, making it a high-dose formula for those looking to specifically supplement their intake. This is ideal for informed consumers, vegans, or anyone who spends little time outdoors.
Most vitamin D3s on the market are extracted from lanolin, a waxy substance from sheep's wool. GEN opts for an alternative source: lichen. Chemically, the result is the same cholecalciferol, but the origin is plant-based. For those following a vegan lifestyle, this is a significant difference. Your body normally produces vitamin D3 in the skin under the influence of sunlight. In autumn and winter, or if you stay indoors a lot, this production drops sharply. This is precisely why so many people turn to a supplement during the darker months. Vitamin D3 contributes to the normal absorption and utilization of calcium and phosphorus. Furthermore, vitamin D3 contributes to the normal functioning of the immune system, the maintenance of normal bones and teeth, and normal muscle function. Vitamin D also plays a role in the process of cell division. Additionally, vitamin D is necessary for normal growth and bone development in children. This wide range of functions explains why vitamin D is one of the most supplemented vitamins, especially in countries with scarce winter sun.
What many people don't know: vitamin D3 and vitamin K2 work as a team. Vitamin D3 contributes to normal blood calcium concentrations. But calcium then needs to get to the right place, namely your bones. This is where vitamin K2 comes in. Vitamin K contributes to the maintenance of normal bones and normal blood clotting. MK-7 (menaquinone-7) is the form of K2 that your body retains longest in the bloodstream. The K2 in this tablet is K2VITAL®, a standardized raw material with 99.7% all-trans MK-7. This all-trans form is relevant because your body retains it better and longer than the cis form. The half-life of MK-7 is also longer than that of K1 or MK-4, resulting in more stable levels in the blood. Thus, the two vitamins complement each other in one tablet.
With 5,000 IU of vitamin D3 per tablet, you are well above the usual maintenance dose of 400 to 1,000 IU per day. This is a deliberate choice. The recommended use is indeed one tablet every five days. This way, you spread the high dose over a longer period, instead of taking it daily. The 200 µg of K2 per tablet corresponds to the amount often used in clinical studies. Both vitamins are fat-soluble. This means your body absorbs them better when you take them with a meal containing some fat. An avocado toast or a handful of nuts is already sufficient. Many wonder if 5,000 IU is not too much; by taking the dose only once every five days, the average daily intake remains limited. If you want to know exactly where you stand, you can have your vitamin D levels measured by a blood test at the doctor and adjust your intake accordingly.
The tablet has a short ingredient list. Besides vitamin D3 and K2, it only contains microcrystalline cellulose as a filler and stearic acid, nothing more. No gelatin, no shellac, no animal-derived additives. The entire formula is vegan and laboratory-tested. A jar contains 180 tablets. At one tablet every five days, you have enough for over nine months, which is convenient if you don't want to reorder constantly. Thus, with this D3 from lichen, combined with K2VITAL®, you maintain clear and fully plant-based supplementation. Good to know: since the product contains vitamin K2, it is less suitable if you are taking anticoagulant medication of the vitamin K antagonist type. In that case, consult your doctor first.
Most vitamin D3 supplements use lanolin from sheep’s wool. GEN extracts the D3 in this product from lichen. A chemically identical cholecalciferol, but entirely plant-based.
The K2 in this tablet is K2VITAL®, a raw material standardised to 99.7% all-trans menaquinone-7. This is the form with the longest half-life in the bloodstream. The dosage of 200 µg corresponds to what is often used in clinical studies.
With a recommended use of one tablet every five days, one jar will last you for over nine months. This makes it convenient if you don't want to keep reordering.
Excipients are limited to microcrystalline cellulose and stearic acid. No gelatin, no shellac, no additives of animal origin. The entire formula is vegan and laboratory tested.

Vitamin D is the collective name for two forms: D2 (ergocalciferol) and D3 (cholecalciferol). D3 is the form that your skin produces itself under the influence of sunlight and which your body generally converts more efficiently into the active form. That is why D3 is more often used than D2 in supplements.
Vitamin D3 contributes to the normal absorption of calcium. But the calcium must then go to the right place in your bones, and not in your blood vessels. Vitamin K2 activates proteins that direct calcium to bone tissue. So they complement each other: D3 makes calcium available, K2 helps to get it to the right place.
Compared to the standard maintenance dose of 400 to 1,000 IU per day, 5,000 IU is indeed high. This is why the recommended use for this product is one tablet every five days, not daily. This way, you spread the dose over a longer period. If you want certainty about your vitamin D level, you can have it measured by a blood test at your doctor's.
Vitamins D3 and K2 are fat-soluble, so their absorption improves if you take them with fats. In an oil capsule, this fat is already present. With a tablet, you solve this by taking it with a meal containing fats, such as an avocado sandwich or a handful of nuts. As long as you do this, a tablet can work just as well.
K2VITAL® is a raw material that is standardised to 99.7% all-trans menaquinone-7 (MK-7). This all-trans form is relevant because your body retains it better and for longer in the bloodstream than the cis form. MK-7 also has a longer half-life than vitamin K1 or the shorter K2 form MK-4, which results in more stable serum levels.
Chemically, the end result is identical: cholecalciferol. The difference lies in the source. Lanolin is extracted from sheep's wool, while lichen is a plant-based source. For your body, there is no difference; the substance works the same way. However, for those who follow a vegan lifestyle, the origin is indeed relevant. This product uses D3 from lichen.
