How to Use Your Bioptimizers Discount Code at Checkout
- Step 1. Add your product to the cart at bioptimizers.com. The site lets you toggle between one-time purchase and Subscribe-N-Save. Pick one-time purchase, because FDN10 only applies to one-time orders.
- Step 2. Click the cart icon and hit “Check Out.” You land on the checkout page with three sections, contact, shipping, and payment.
- Step 3. Find the “Discount code or gift card” field on the right side of the checkout page above the order summary. Paste FDN10 and click Apply.
- Step 4. Confirm the 15% line item shows in the order summary before you pay. The discount appears as a negative number labeled “FDN10.”
If the field rejects the code, refresh the page, switch your cart back to one-time purchase, and try again. The most common failure happens when shoppers leave Subscribe-N-Save toggled on.
What FDN10 Applies To (and What It Does Not)
FDN10 works on every one-time product page at bioptimizers.com, including Magnesium Breakthrough, Sleep Breakthrough, MassZymes, Probiotic Breakthrough, Cognibiotics, and all bundle SKUs.
The code applies before tax and shipping. No minimum order.
FDN10 does NOT stack with Subscribe-N-Save. Subscribe-N-Save already applies a 25% recurring discount, and Bioptimizers blocks promo codes on that pricing tier.
FDN10 also does not stack with bundle-page promotions that already show a struck-through price, since those bundles run on a pre-applied discount that conflicts with promo code logic.
You can use FDN10 even if you have ordered from Bioptimizers before. The code carries no first-time-customer restriction.
Real Savings With FDN10 on Bioptimizers Top Sellers
The numbers below pull from current bioptimizers.com pricing as of May 2026. Your final price after FDN10 looks like this.
| Product | Regular Price | Price With FDN10 | You Save |
|---|---|---|---|
| Magnesium Breakthrough (60 caps) | $40.00 | $34.00 | $6.00 |
| Sleep Breakthrough (60 caps) | $58.00 | $49.30 | $8.70 |
| MassZymes (250 caps) | $80.00 | $68.00 | $12.00 |
| Probiotic Breakthrough (60 caps) | $50.00 | $42.50 | $7.50 |
| Cognibiotics (60 caps) | $69.00 | $58.65 | $10.35 |
| Magnesium Breakthrough 5-bottle bundle | $390.00 | $331.50 | $58.50 |
| Sleep Breakthrough 5-bottle bundle | $325.00 | $276.25 | $48.75 |
The 5-bottle bundles deliver the biggest dollar savings because the discount scales with cart total. If you plan to use a Bioptimizers product for 4+ months, the bundle path saves you more than re-ordering single bottles even when you stack FDN10 on each single order.
FDN10 vs Subscribe-N-Save: Which One Saves You More
Subscribe-N-Save gives you 25% off plus 1.5% BIObucks back on every recurring shipment. FDN10 gives you a flat 15% off on a one-time order with no recurring commitment.
The right answer depends on how long you plan to take the product.
Run the math on Magnesium Breakthrough at $40 a bottle. Subscribe-N-Save drops it to $30 per shipment, and 12 monthly shipments cost you $360 plus $5.40 in BIObucks back.
FDN10 drops a one-time bottle to $34, and 12 one-off orders cost $408. Subscribe-N-Save wins by $48 a year if you stay committed.
Subscribe-N-Save loses when you forget to skip a shipment, end up with 14 bottles in a closet, and cancel after three months. If you want to test a product first, FDN10 protects you from auto-renewal lock-in.
- Pick FDN10 for first-time trials and bundle purchases.
- Pick Subscribe-N-Save once you know the product belongs in your daily routine.
Free Shipping Thresholds at Bioptimizers
Bioptimizers gives you free shipping on US orders above $90, Canadian orders above $150, and international orders above $200.
The free-shipping check runs on your post-discount cart total. Applying FDN10 to a $99 cart drops it to $84.15, which falls below the US threshold and triggers a shipping fee.
Add a low-cost item or pick a bundle to clear the threshold after the discount applies. A single $40 Magnesium Breakthrough plus a $58 Sleep Breakthrough lands at $83.30 after FDN10, still short of the $90 line. Add a third single bottle, or swap to a 3-bottle bundle, to ship free.
BIObucks Loyalty Program (Stack It With FDN10 Smartly)
Bioptimizers runs a free loyalty program called BIObucks. You earn 1% back on one-time orders and 1.5% back on Subscribe-N-Save orders, redeemable as store credit on future purchases. The program also pays $10 in BIObucks for each friend’s one-time order made through your referral link and $15 for each friend’s subscription order.
BIObucks calculate on your post-discount total. A $40 bottle of Magnesium Breakthrough at $34 after FDN10 earns you $0.34 back. The earnings stay small on single orders, but a $331.50 bundle purchase after FDN10 earns $3.32 back, plus you keep the 15% upfront savings.
Sign up for BIObucks before you place your first FDN10 order so the credit posts to your account automatically.
Is FDN10 Legit? Why Coupon Viking Verifies This Code
Coupon Viking partners with Bioptimizers directly and requests codes that do not expire. FDN10 came from that partnership.
The code displays “FDN10” at checkout but applies 15% off, because the brand assigned the discount value to the code name independently. The name does not match the discount percentage, and that confuses some shoppers into thinking the code is broken.
Coupon Viking lists one verified code per brand instead of stuffing the page with 30 dead codes. You spend less time guessing and more time at checkout.
The verification date stamp on this page updates every 30 days. If FDN10 ever stops working, you can report it through the contact form and Coupon Viking will replace it within 48 hours.
Best-Selling Bioptimizers Products Worth the 15% Off
Magnesium Breakthrough delivers 500mg across 7 forms of magnesium per serving, including glycinate, malate, citrate, orotate, sucrosomial, taurate, and chelate. Each form targets a different tissue, so the blend covers sleep, muscle relaxation, and stress response in one capsule. This product drives 60%+ of Bioptimizers sales.
Sleep Breakthrough pairs GABA, L-tryptophan, and magnesium glycinate in a non-habit-forming formula. The drink version comes in chocolate or mint and dissolves in water 30 minutes before bed. The capsule version skips the flavoring for shoppers who travel.
MassZymes packs 17 digestive enzymes per capsule, including a high dose of protease for protein breakdown. Active gym-goers and high-protein eaters use it to reduce bloating after 40g+ protein meals.
Probiotic Breakthrough uses Lactobacillus Plantarum OM, a heat-stable strain that survives stomach acid without enteric coating. Each bottle holds 60 capsules at 25 billion CFU per serving.
Cognibiotics targets the gut-brain axis with 10 probiotic strains plus 9 nootropic herbs. Shoppers stack it with Magnesium Breakthrough for mood and focus support.
