Withanly Vanilla Whey Protein Isolate tub on cream linen

Bottle, label, capsule, and packaging appearance may vary slightly from images shown.

You've been mixing the same sucralose-bomb tub for so long you forgot a vanilla shake can taste like vanilla. 22 grams of whey protein isolate per serving, sweetened with stevia leaf extract, flavoured naturally, smoothed with sunflower lecithin so it actually mixes. No artificial sweeteners, no artificial dyes, no chemical aftertaste at the bottom of the shaker.

Genuinely clean vanilla. I was tired of sucralose-bomb proteins.

The formula

Six things to know about what's in the bottle.

  • Organic ashwagandha root, 650mg
  • Black pepper for absorption
  • Vegan pullulan capsule
  • Standardised for potency
  • No fillers or flow agents
  • Bottled in the USA, GMP-certified

A quieter system

Three ways the shift shows up.

22g — without the filler.

Macro

22g — without the filler.

Most cheap proteins pad the scoop with maltodextrin and fillers. This is the actual 22 grams the label promises, in the form your muscle actually uses.

Smooth in a shaker, clean in cold water.

Mixability

Smooth in a shaker, clean in cold water.

Sunflower lecithin acts as a natural emulsifier — the reason this mixes without clumps in 10 seconds, not 60. MCT oil powder adds a light creaminess without separating.

Vanilla. Like the actual flavour.

Taste

Vanilla. Like the actual flavour.

Stevia leaf extract and natural vanilla flavouring, no sucralose chemical sting, no neon-yellow dye, no artificial coffee-creamer aftertaste at the bottom of the shaker.

What's inside

The label is the whole story.

Every ingredient, the form we use, the dose per serving, the mechanism that makes it relevant, and the peer-reviewed study that backs it.

Proprietary blend

MCT Oil Powder

Form: Included in 34 g serving (exact mg not disclosed on label)

Medium-chain triglycerides derived from coconut or palm kernel oil. Adds a light creaminess to the powder and may support sustained energy; rapidly absorbed compared to long-chain fats.

Proprietary blend

Apple Pectin Powder

Form: Included in 34 g serving (exact mg not disclosed on label)

A soluble dietary fibre derived from apples. Used as a natural thickener and texture agent in the powder matrix; contributes to the smooth mouthfeel.

Proprietary blend

Sunflower Lecithin

Form: Included in 34 g serving (exact mg not disclosed on label)

A natural phospholipid emulsifier sourced from sunflower seeds. Improves powder dispersibility in water and prevents clumping — the main reason this formula mixes cleanly in a shaker without a blender.

Proprietary blend

Stevia Extract (leaf)

Form: Included in 34 g serving (exact mg not disclosed on label)

A plant-derived, zero-calorie sweetener extracted from stevia rebaudiana leaves. Provides sweetness without spiking blood sugar, used as a cleaner alternative to artificial sweeteners like sucralose.

Proprietary blend

Sea Salt

Form: Contributing to 115 mg Sodium per serving

Provides sodium (115 mg per serving), an essential electrolyte for muscle contraction, nerve function, and hydration balance during training.

Proprietary blend

Silicon Dioxide

Form: Trace anti-caking agent in 34 g serving

A naturally occurring mineral used as an anti-caking agent to maintain powder flowability and prevent clumping during storage.

Proprietary blend

Vitamin D

Form: 4 mcg (160 IU) per serving — 18% Daily Value

Fat-soluble vitamin essential for calcium absorption, bone mineralisation, and immune function. Naturally present in whey at trace levels; supports the calcium provided in this formula.

105 mg per serving

Calcium

Form: 105 mg per serving — 8% Daily Value (naturally occurring from whey)

An essential mineral for bone density, muscle contraction, and nerve signalling. Naturally occurring from the whey protein isolate source.

63 mg per serving

Phosphorus

Form: 63 mg per serving — 5% Daily Value (naturally occurring from whey)

Works with calcium to build and maintain bone structure. Also integral to ATP production — the energy currency of muscle cells during exercise.

21 mg per serving

Magnesium

Form: 21 mg per serving — 5% Daily Value (naturally occurring from whey)

An essential mineral involved in over 300 enzymatic reactions, including muscle relaxation and protein synthesis. Naturally present from the whey source.

110 mg per serving

Potassium

Form: 110 mg per serving — 2% Daily Value (naturally occurring from whey)

A key electrolyte for fluid balance, muscle contraction, and post-exercise recovery. Naturally occurring from the whey protein isolate.

Honest answers

Questions you actually asked

Is it lactose-free?

Whey isolate has dramatically less lactose than concentrate (typically under 1 g per scoop), but it's not strictly lactose-free. Most people who tolerate dairy at all tolerate whey isolate. Strict lactose-intolerance: skip this and look at a plant-based option.

How much protein is actually in each serving?

22 grams of protein per serving (2 scoops / 34 g). That's what the Supplement Facts panel states — no protein spiking, no amino acid inflation.

How does it mix?

Cleanly with a shaker — 10 seconds, no clumps, thanks to the sunflower lecithin emulsifier. Smoother still in a blender if mixing with frozen fruit or oats.

Why sunflower lecithin instead of soy lecithin?

Sunflower lecithin achieves the same emulsification without the soy allergen concern. It's cold-pressed from sunflower seeds — a cleaner option for people avoiding soy.

What does apple pectin powder do in the formula?

It's a natural, soluble fibre from apples used as a texture agent. It contributes to the smooth, slightly thick mouthfeel rather than the chalky grit you get from cheaper filler-loaded powders.

How does it taste?

Natural vanilla — closer to a French-vanilla custard than a candy-store vanilla. Less aggressively sweet than sucralose-loaded proteins because it's sweetened with stevia leaf extract.

When should I take it?

Post-workout (within 60 minutes) is the classic timing for muscle-protein-synthesis applications. Otherwise, any time of day — daily protein totals matter more than precise timing for most people.

Is it vegetarian?

Yes — it carries the Vegetarian dietary tag from the manufacturer. It is not vegan, as whey protein is a dairy-derived ingredient.

Can I take it with my ashwagandha?

Yes — they don't conflict. Common stack for active adults: whey post-workout + ashwagandha daily + creatine.

Is it safe to take daily?

Yes for most healthy adults. Protein needs scale with body composition and training volume. If you have kidney conditions or are unsure of your protein needs, talk to a registered dietitian.

What if it doesn't work for me?

Email contact@withanly.com within 30 days of delivery and we'll refund the full amount — you don't need to send the tub back.

How fast does it ship?

From our US warehouse, USPS Ground typically arrives in 2–4 business days within the contiguous US.
