Supplement Storage and Expiry in Indian Conditions

Supplements degrade with heat, humidity and light, and Indian conditions supply all three. Whey and other powders absorb moisture and clump, and a sour or off smell means the tub is finished regardless of the printed date. Fish oil oxidises and a rancid smell is the sign. Probiotics often need refrigeration and the label says so. Vitamins lose potency in heat and light rather than becoming unsafe. Creatine is stable dry and degrades once mixed. A best-before date describes quality in an unopened, correctly stored pack, and an opened tub has a shorter life than the date implies. Store in a cool cupboard away from the stove and the bathroom, keep the desiccant sachet in, keep the scoop dry, close the lid fully, inspect a delivery on arrival in summer, and in monsoon buy tub sizes you will finish within a month or two.

1. Heat, humidity and light are the three enemies: Most supplement labels say store in a cool, dry place away from sunlight, which in an Indian summer kitchen at 40 degrees or a monsoon month at 90 percent humidity is not the default. The kitchen counter near the stove and the bathroom shelf are the two worst places in most homes; a cupboard in an interior room is usually the best. 2. Powders absorb moisture and clump: Whey, plant protein and pre-workout powders pull moisture from the air every time the lid is open. Clumping is the early sign; a sour, stale or off smell means the tub is finished, whatever the printed date. Keep the desiccant sachet in the tub, use a dry scoop, close the lid fully and quickly, and never scoop with a wet spoon. 3. Fish oil oxidises, probiotics need cold: Omega-3 capsules oxidise in heat and light, and a rancid or strongly fishy smell when the bottle is opened is the sign; keep them cool and dark, and refrigeration after opening is reasonable in summer. Many probiotic products need refrigeration and the label states it; a probiotic that travelled unrefrigerated has been through conditions its label did not assume. 4. Vitamins lose potency rather than becoming unsafe: Heat and light reduce the potency of most vitamins over time, so a bottle stored badly delivers less than the label states rather than something harmful. Creatine monohydrate is stable dry and degrades in liquid, so mix it when you use it. Gummies and softgels soften and stick together in heat and are the formats most affected by an Indian summer. 5. Best before is about quality, and the clock restarts on opening: A best-before date describes an unopened pack stored as the label directs. Once opened, the product is exposed to air and moisture each time, and its useful life is shorter than the date - for powders often a couple of months in humid conditions. Buy tub sizes you will finish, and in monsoon prefer smaller ones even at a higher cost per serve. 6. Transit is storage too: A courier van in May can exceed 50 degrees inside. Inspect a delivery on arrival: a powder that has clumped in transit, capsules that have fused, or a seal that has lifted are reasons to return it within the window. The genuine supplement guide covers the seal and batch checks; this is the additional summer check. 7. Read the storage line on the label: The supplement label guide covers the label as a whole. The storage instruction on it is the manufacturer stating the conditions the product was tested under, and a product kept outside them is not the product the label describes, whatever the date says.

Store supplements in a cool cupboard in an interior room, away from the stove, the bathroom and direct sunlight. Keep the desiccant sachet in, the scoop dry and the lid closed fully. Treat clumping as a warning and an off smell as the end of the tub, whatever the printed date. Keep fish oil cool and dark and refrigerate probiotics where the label says so. Inspect deliveries on arrival in summer and return anything that has clumped, fused or lost its seal. Buy sizes you will finish, and smaller ones in monsoon. This page is about keeping a product in the condition its label describes. It is not guidance on whether to take a supplement, in what amount, or whether one suits a medical condition, pregnancy or existing medication, which are questions for a doctor or a registered dietitian.
