Follow BiOptimizers on social media
This helps you catch time-sensitive discounts once they are available. For example, during this year's Prime Day, BiOptimizers posted discounts of up to 35% on select supplements. Plus, you can turn on notifications if you really don't want to miss out on their promotions. Although they have other accounts available, for savings, we recommend their Instagram and Facebook. You don't have to follow both since their postings are pretty much the same. This is mostly really useful for repeat shoppers or those who plan to buy again from them.

Frequently asked questions about BiOptimizers
BIOptimizers rewards program
This program works best for repeat buyers who reorder supplements often. We don't recommend it for one-time shoppers since the return is quite small. For one-time orders, you'll only receive 1% back, and even for Subscribe 'N Save orders, you'd only get a 1.5% return.
The fastest way to collect BIObucks would be referrals. You get $15 in BIObucks each time your friend places a subscription order. But of course, finding people who are willing to subscribe could be a difficult task in itself.
The good thing is, becoming a member is easy; go to their BIObucks page and enter your email in the sign-up field. Then, when you want to redeem your BIObucks, log in to your account and apply them at checkout. It works similarly to a discount code.
How to use a coupon code on BiOptimizers
Follow these steps:
Browse and add the products you want to your cart.
Click the cart icon to start reviewing your items.
Make sure your subtotal meets any minimum spend required by the coupon code you plan to use.
Click "Proceed to Checkout" to move to the payment page.
Find the field with "Coupon Code" in it.
Enter your coupon code in this field.
Click "Apply" to activate the discount. Your savings will appear in the order summary.
Review your updated total, then complete your purchase.
Since only one code can be used per purchase, try and apply the codes to see which gives you the best savings. Also, for members, rewards are only calculated on the amount you actually pay. This means that you will not earn reward points on any portion of an order covered by coupon codes.
Wait for one of BiOptimizers' seasonal sales
This is one of the best tips to save on their supplements. Based on past sales over the last two years, discounts tend to fall in these ranges:
Themed wellness events, such as Sleep Week or International Women's Day, offer discounts up to 20% on select products.
Major shopping holidays bring the best value with each purchase. During last year's Black Friday and Cyber Monday events, we saw up to 25% off sitewide, free shipping on orders over $99, and tiered free gifts. Gift thresholds started around $150 and increased at $250 and above.
