COMPARISON
Nula vs OLLY Goodbye Stress — which should you pick?
olly goodbye stress is a swallowed gummy with gaba, l-theanine and lemon balm, plus sugar and gelatin. nula is a sugar-free, vegan gum with l-theanine and gaba that you chew and discard. both publish their ingredient amounts; format, base ingredients and how you prefer to take a supplement help distinguish them.

different jobs, not better or worse
olly goodbye stress is a daily gummy — its label says take two a day as needed, swallowed like any gummy. olly's own page says its gaba 'starts working within 30-60 minutes', the timeline you would expect from anything that has to clear the stomach and gut first. that is the routine end of the shelf: something you build into a day.
nula is the other end. a gum you chew and hold in the mouth for a few minutes, made for the ten minutes before something starts rather than a daily slot, with the contents against the lining of the mouth instead of taking the long route through the gut. same category on paper, opposite use in practice — and that is the difference that actually decides between them.
the doses, side by side
both brands print their amounts, and they land close. nula's label says l-theanine 100mg and gaba 50mg per serving. olly's supplement facts list gaba 100mg, l-theanine 50mg and lemon balm extract 75mg per two-gummy serving.
they lean opposite ways — nula puts more into l-theanine, olly more into gaba and adds lemon balm — but the totals sit in the same range. dose is not what separates these two. format and base are.
what is in the base
olly's other ingredients, as listed on their page, include glucose syrup, sugar and gelatin. the gelatin means the gummies are not vegan, and the sugar is real sugar — two grams a serving.
nula's base is xylitol, natural chicle gum base, erythritol, peppermint powder and plant-derived binders, with monk fruit and stevia for sweetness. no sugar, no gelatin, no aspartame. it is worth noting that xylitol is toxic to dogs, so keep it away from pets.
olly's product carries nsf certification, which nula does not currently claim. if independent certification is your deciding factor, that one goes to olly.
common follow-ups
100mg per two-gummy serving, listed on its supplement facts. it also lists 50mg l-theanine and 75mg lemon balm extract per serving.
no. its listed other ingredients include gelatin, which is animal-derived. nula's gum is vegan.
closer than the pack prices suggest. count one piece as a serving and nula is $36.21 for 56 — about $0.65 each — against olly's $13.99 for 21, about $0.67 each. so per serving nula is a touch cheaper; olly only wins if you chew two pieces at a time.
