Ellie was founded in 2022 in Boston, Massachusetts by Dr. Eleanor “Ellie” Marcus, a nutrition scientist trained at Harvard School of Public Health, together with a team of 14 wellness entrepreneurs.
At Ellie, we believe daily wellness should be both clinically reliable and delightfully simple
Our mission was clear from the start: to solve the two biggest problems in supplements -pill fatigue and underperforming gummies. Capsules are effective but difficult to sustain in daily routines. Gummies promised a fun alternative, yet too often came with added sugar, low potency, and poor stability in heat or storage.
Ellie was built as the next generation of nutrition delivery. Powered by our patented BioShield™ Technology, Ellie jellybeans lock in nutrients by protecting them against oxygen, moisture, and time. The result is a supplement that delivers capsule-level effectiveness, remains 3X more potent than gummies, and is genuinely enjoyable to take every day.
