BioHealth Nutrition Precision ISO Protein Review: Pasture-Fed Whey Isolate

What It Is

Precision ISO is BioHealth Nutrition's flagship whey protein isolate, described by the brand as its bestseller. Each serving delivers 27g of protein sourced from pasture-fed whey, along with 1g of carbs and 0g of fat per serving (macros can vary slightly by flavor). The formula is sugar-free, low-carb, fat-free, sweetened with stevia, and free of synthetic fillers according to the product page. It comes in an extensive flavor lineup — Vanilla, Chocolate, Fruity Cereal, Cookies & Cream, Strawberry Shortcake, Chocolate Peanut Butter, Horchata, Peanut Butter Cookie, Mochaccino, Scout's Honor, Mochi Donut, and Hot Cocoa.

A Sizing Note

Worth flagging: the URL for this listing references a "2lb" size, but the actual size options shown on the live product page are 1lb, 1.5lb, and 4lb — there's no 2lb option currently listed. Shoppers should double-check the size selector directly on the page before ordering to make sure they're getting the quantity they expect.

Price and Reviews

Precision ISO is priced at $64.99, discounted from a regular $69.99. It carries a strong 4.7 out of 5 average across a substantial 308 reviews, which is a meaningfully large sample size and lends more confidence to the rating than many of the smaller-review-count products in this category.

Bottom Line

With a large, positive review base and an unusually wide flavor selection, this looks like a well-established option in BioHealth's protein lineup. The one thing to sort out before ordering is confirming the actual size you're purchasing, since the listing's "2lb" naming doesn't match the sizes currently offered on the page.

Pros: Strong 4.7-star rating from 308 reviews, wide flavor variety, sugar-free and low-carb formula.
Cons: URL/size naming mismatch (listed as "2lb" but page offers 1lb/1.5lb/4lb) — confirm size before ordering.
