Genexa’s mission is to be the leader in cleaner, safer, healthier over-the-counter (OTC) medicines and wellness products. Genexa is determined to create innovative products with a sustainable focus and a desire to contribute to a better world.


Genexa was founded by David Johnson and Max Spielberg, two dads who were looking for cleaner, healthier medicines for their kids, but couldn’t find any. Determined to create cleaner options for the whole family, they formed Genexa to deliver OTC medicines and wellness products made with organic and non-GMO ingredients, like Vitamin D3 for Infants.


Unlike many OTC medicines and supplements that contain potentially harmful inactive ingredients, Genexa Vitamin D3 for Infants is free of artificial dyes, flavors and preservatives, and does not contain allergens such as gluten and lactose. Vitamin D3 for Infants is USDA Certified Organic, Non-GMO Project Verified, Certified Gluten-Free and Certified Kosher.


Unlike many vitamin D supplements available today, Genexa Vitamin D3 for Infants contains a form of vitamin D3 (as cholecalciferol) derived from a kosher source. It is also free of gelatin and casein. Labeling Vitamin D3 for Infants as certified kosher gives parents peace of mind that they can choose a cleaner, healthier option for their child.

Receiving the kosher certification is important to Genexa in its mission to make cleaner, safer, healthier products more accessible. “Everyone deserves the opportunity to make a cleaner choice for their family, regardless of religious beliefs,” commented David Johnson, co-founder and CEO of Genexa. “Working with the Orthodox Union to add the OU kosher symbol to our packaging is an important milestone and creates an opportunity to give parents access to cleaner options for their families.”
